The present invention relates to a fetal reprogramming effect of a PPAR δ agonist, and more particularly, to a new use of a PPAR δ agonist, which adjusts calcium ions during embryo genesis and a early fetal development period to increase slow muscle fibers and thus enhance muscle endurance, thereby improving lipid and glucose metabolism and reprogramming the metabolism of the entire body and thus preventing/inhibiting the occurrence of metabolic diseases, such as obesity and diabetes in an adult or adult body caused by high-fat diet and lack of exercise, and improving memory. According to the present invention, the PPAR δ agonist prevents/inhibits the occurrence of diabetes even in a mouse with congenital diabetes as well as controls fetal reprogramming in a normal mouse, and thus is effective in the prevention of metabolic diseases such as obesity, diabetes, and the like, and treatment of premature children through the fetal reprogramming in human beings and animals and also is effective in enhancing endurance and improving memory of human beings and animals.
Skeletal muscles may be divided into a slow muscle fiber and a fast muscle fiber based on the muscle contraction rate and metabolism characteristics (Schiaffino & Reggiani Physiol. Rev., 1996, 76, 371-423). The fast muscle fiber, which is Type II muscle fiber, uses glucose as an energy source, and is commonly present in the muscles needed for fast movement such as sprinting. On the other hand, the slow muscle fiber uses lipid as a main energy source, and are commonly present in the muscles needed for continuous movement. The slow muscle fiber has more mitochondria than the fast muscle fiber and thus appears redder than the fast muscle fiber, and has resistivity against fatigue due to lactic acid at the time of exercise and thus is appropriate in the exercise requiring endurance (Costill, D L. et al., J. Appl. Pysiol., 1976, 40, 149-154; Saltin B et al., Ann. N.Y. Acad. Sci., 1977, 301, 3-44). In addition, since the slow muscle fiber is greater than the fast muscle fiber in view of fatty acid oxidative capacity and insulin sensitivity, metabolic diseases such as obesity and diabetes were remarkably suppressed in spite of the intake of high-fat feedstuff (35% V/V lipid) (Wang, Y X. et al., Plos Biol., 2004, 2, e294; Vihang A. Narkar et al, Cell, 2008, 134, 405-415).
It has been known that there are Calcineurin (Serrano, A L. et al., Proc. Natl. Acad. Sci. USA., 2001, 98, 13108-13113), Calmodulin-dependentkinase (Wu, H. et al., Science., 2002, 296, 349-352), PGC-1α (Lin, J. et al., Nature., 2002, 418, 797-801), AMPK (Vihang A. Narkar et al, Cell, 2008, 134: 405-415), Sirt1 and Adiponectin (Masato Iwabu et al., Nature, 2010, 464, 1313-1319), and PPAR δ (Wang, Y X. et al., Plos Biol., 2004, 2, e294) in genes associated with fast-to-slow muscle fiber transformation. Of these, PPAR δ has been found to be a very important modulator in the fast-to-slow muscle fiber transformation through studies on overexpression or selective removal thereof. PPAR δ is a ligand-dependent transcription factor that is commonly expressed in the slow muscle fiber. It has been reported that muscle-specific PPAR δ transgenic mice showed a significant increase in generation of slow muscle fibers, and thus 67% and 92% increases in the running time and distance, respectively (Wang, Y X. et al., Plos Biol., 2004, 2. e294). Whereas, it has been reported that mice of which PPAR δ gene was selectively removed showed a 62% decrease in the running time and also a 66% decrease in the running distance as compared with normal mice (Wang, Y X. et al., Plos Biol., 2004, 2. e294). Therefore, it may be seen that PPAR δ is an important gene in generating the slow muscle fiber and controlling exercise capacity.
However, it has been reported that study results using PPAR δ agonist were completely different from the anticipation from the existing studies. GW501516 is the most effective in PPAR δ agonists as reported in documents until now (William R. Oliver, Jr. et al., Proc. Natl. Acad. Sci. USA., 2001, 98, 5306-5311). It has been reported that experiment results using this material were different from those using the existing PPAR δ transgenic mice. In other words, administration of GW501516 alone to an adult did not show improvement in slow muscle fibers and endurance, but only the simultaneous combination of exercise and administration of GW501516 generated slow muscle fibers and enhanced endurance (Vihang A. Narkar et al, Cell, 2008, 134, 405-415). Accordingly, few cases have been known until now where the PPAR δ agonist alone enhances endurance.
Fetal programming is a theory where the environment to which the fetus is exposed during a gestation period determines health of a fetus and an adult, which was first discussed in Southampton University and Kings College, UK, and is currently used with the term “developmental programming” and “fetal developmental programming” More specifically, this means that the environment to which the fetus is exposed during a development period influences generation of organs and viscera of the fetus, which then influences the whole life (Mc-Millen and Robinson, Physiol Rev., 2005, 85, 571-633; Plagemann, Horm Res., 2006, 65, 8389; Taylor and Poston, Exp Physiol, 2007, 92, 287298). Epidemiological investigation results reported that an excessive supply or an insufficient supply of nutrient during a fetal programming period causes an increase in the occurrence of serious diseases such as obesity, cardiovascular disease, diabetes, hypertension, arteriosclerosis, and cancer, as an adult. For this reason, various studies have been conducted to prevent them, and a representative example therefor is taurine or the like. It has been known that the intake of taurine during the development period suppresses the occurrence of diabetes (Chemf et al., J. Endocrinol., 1998, 159, 341-348), and it has been known that arginine improves diabetes and cardiovascular disorder (Wu et al., J. Nutr., 2004, 134, 2169-2172). In addition, it has been known that folic acid which pregnant women take a lot in order to suppress miscarriage is also effective in preventing the diabetes (Lillycrop et al., J. Nutr., 2005, 135, 1382-1386). Very interestingly, it has been reported that administration of exedin-4, which is a GLP-1 agonist and has a diabetes treatment effect, during a development period of a rat, can decrease oxidative stress and thus prevent fetal diabetes (Stoffers D A et al., Diabetes. 2003, 52, 734-740; Raab E L et al., Am. J. Physiol. Regul. Integr. Comp. Physiol., 2009, 297, 1785-1794).
The present inventors validated a fetal reprogramming effect of a PPAR δ agonist, and then completed the present invention. The present invention confirmed the effect of PPAR δ by using a method of administrating an agonist to a mother during a pregnant period and a lactancy period (maternal treatment). As a result, the PPAR δ agonist alone adjusted calcium ions and thus increased generation of slow muscle fibers. Mouse pups subjected to fetal reprogramming with the PPAR δ agonist had significantly enhanced endurance even though they were not administered with the PPAR δ agonist or did not exercise after growing to adults. Further, the occurrence of metabolic diseases such as obesity and diabetes, caused by the intake of high-fat and lack of exercise, was significantly prevented and suppressed, and new effects of improving memory was validated. Moreover, it was validated that the PPAR δ agonist alone prevents/suppresses the occurrence of diabetes from birth to adulthood even in the case of db/db mice, which is a congenital diabetes disease model, as well as, normal mice.
The present invention is directed to a fetal reprogramming effect of a PPAR δ agonist, and an object of the present invention is to increase activity of PPAR δ protein by using a compound during the development period of a human being and an animal and thus increase slow muscle fibers and enhance endurance, thereby fundamentally preventing or reducing the occurrence of metabolic diseases, and improving memory. In the present invention, the PPAR δ agonist alone was used without exercise, to increase slow muscle fibers of a human being or an animal and thus significantly enhance endurance; to reprogram the metabolism of the entire body and thus fundamentally prevent or suppress the occurrence of metabolic diseases; and to improve the memory, which are completely different from as reported by the existing inventions (WO 2009/086526, WO2008/083330). More progressive is that the fetal reprogramming effect of the PPAR δ is consistent with mice born with a congenital diabetes disease as well as normal mice.

Another object of the present invention is to provide a fetal reprogramming method of a mammal excluding a human being, including administering a PPAR δ agonist to the mammal except the human being.

Hereinafter, the present invention will be described in detail.
The present invention is directed to a fetal reprogramming effect of a PPAR δ agonist during a development period of a mammal, and the present invention is directed to effects of enhancing muscle endurance, preventing and suppressing metabolic diseases such as obesity, diabetes, atherosclerosis, and fatty liver, and improving memory, through fetal reprogramming of the PPAR δ agonist during development periods of all animals including a human being.
The present inventors used a method of administering medicine to a pregnant mother (maternal treatment) and a method of administering medicine to a lactating mother. However, the present invention is not limited to the two methods, and includes PPAR δ fetal reprogramming methods through other pathways except for the administration methods used in the present invention. The present invention includes, for example, a method of increasing expression and activity of PPAR δ in a fetus through a mother animal, and a method of directly increasing expression and activity of PPAR δ in a fetus by using a form of dry milk, baby food, and the like. In addition, the present invention includes an injection, a taker, a skin permeation ointment for a pregnant animal mother and a pregnant woman, containing agonists used in the present invention [CMDD 1111, 1112, 1226] as well as a PPAR δ agonist as an effective component, and fetal reprogramming method of PPAR δ using beverage and food containing a PPAR δ agonist.
According to the existing study result, the PPAR δ agonist was orally administered to the adult and then it was observed whether or not the muscle fiber was changed, but the generation of slow muscle fibers was not increased (Vihang A. Narkar et al, Cell, 2008, 134, 405-415). In the present invention, slow muscle fibers of a born fetus were significantly increased even though the PPAR δ agonist was administered to only a pregnant mother or a lactating mother. Therefore, it may be seen that the fetal reprogramming results by PPAR δ mainly results in an increase in slow muscle fibers and the most important acting time thereof is a myogenesis period.
The slow muscle fiber is characterized by oxidation of fatty acid, biosynthesis of mitochondria, and an increase in protein associated with slow myosin heavy chain and slow contraction. In the mice subjected to fetal reprogrammed by PPAR δ, all the gene groups were increasingly expressed. Further, it may be confirmed from the results of external shape comparison and tissue staining of the muscle that the slow muscle fibers were increasingly generated by the PPAR δ agonist. Taken together of the above two experiments, it may be seen that the fetal reprogramming by PPAR δ agonist can promote generation of the slow muscle.
Calcium has been known as an important regulator that promotes fast-to-slow muscle fiber transformation. According to results of a study by the present inventors, as the result of fetal reprogramming by the PPAR δ agonist, expression of genes such as RYR, ATP2A2, and PLN, which regulate concentration of cytosolic calcium, was remarkably increased in the mouse muscle whereby the retention time of cytosolic calcium ions was significantly increased. This increase in cytosolic calcium ions in the cell activated calcium signals and thus increased generation of slow muscle fibers.
In the present invention, mice with increased slow muscle fibers had 2.9 fold the exercise time as compared with control mice. In order to establish a mechanism thereof, a gene analysis (microarray) experiment using skeleton muscle tissues was conducted. As a result, it was confirmed that expression of genes such as RYR2, ATP2A2, PLN, and MYBPC3, which have been known to be commonly expressed in the heart muscle, was remarkably increased for an administered mice group. To sum the above results up, the fetal reprogramming by the PPAR δ agonist improved muscle functions as well as heart functions in the mice.
The largest meaning of the present invention is that the fetal reprogramming by the PPAR δ agonist compound can improve health and life quality of human beings or animals after growth. As for the mice subjected to fetal reprogramming by PPAR δ, even though the PPAR δ agonist compound was not administered or exercise was not made as adults, the generation of slow muscle fibers and the enhancement of endurance were remarkably increased when the mice became adults, and the occurrence of metabolic syndromes such as obesity and diabetes caused by intake of high-fat and lack of exercise was significantly suppressed.
Obesity is a direct cause of metabolic diseases such as hyperlipidemia, arteriosclerosis, and myocardial infarction as well as diabetes. Therefore, according to the present invention, mice having increased lipid metabolizing capacity through the fetal reprogramming by PPAR δ agonist can have an effect of preventing all metabolic syndromes including obesity.
The slow muscle fiber contains more mitochondria than the fast muscle fiber. The mitochondria are characterized by having maternal inheritance. Therefore, the mice having increased mitochondria through the fetal reprogramming by the PPAR δ agonist can influence mitochondria formation in the next generation, and in advance, enhance endurance and prevent the occurrence of metabolic syndromes of the next generation to which the PPAR δ agonist is never administered.
That is, the present invention provides a composition for fetal reprogramming of a mammal, containing a peroxisome proliferator activated receptor δ (PPAR δ) agonist as an effective component. Further, the present invention provides a fetal reprogramming method of a mammal excluding a human being, including administering a PPAR δ agonist to the mammal excluding the human being. Further, the present invention provides a composition for a food additive, a functional food supplement, or a functional beverage for enhancing muscle endurance, preventing metabolic diseases, or improving memory, of an object produced by a fetal reprogramming method of a mammal including a human being, containing a PPAR δ agonist. Further, the present invention provides a composition for feedstuff for enhancing muscle endurance, preventing metabolic disease, or improving memory, of an object produced by a fetal reprogramming method of a mammal, containing a PPAR δ agonist as an additive. Further, the present invention provides a composition for dry milk or baby food for enhancing muscle endurance, preventing metabolic disease, or improving memory, of an object produced by a fetal reprogramming method of a mammal, containing a PPAR δ agonist as an additive. Further, the present invention provides an endurance enhancer of an object produced by a fetal reprogramming method of a mammal including a human being, containing a PPAR δ agonist as an effective component. Further, the present invention provides an endurance enhancer of an object produced by a fetal reprogramming method of a mammal excluding a human being, containing a PPAR δ agonist as an effective component.

Hereinafter, the present invention will be described in detail by the examples.
The following examples are for merely exemplifying the present invention, and therefore, the scope of the present invention is not limited to the following examples.
1. Fetal Reprogramming Effect by PPAR δ Agonist
The structures of PPAR δ agonists used in the following examples are as follows:
The present inventors used a method of administering a PPAR δ agonist to a pregnant mother (maternal treatment) in order to investigate the role of fetal reprogramming of PPAR δ during mammalian development. For the fetal reprogramming, the PPAR δ agonist was orally administered to pregnant mice at a concentration of 10 mg/kg every day, and a specific experiment method was summarized in
(1) Confirmation on Whether or not PPAR δ Agonist Passes Through Placenta
Pharmacokinetic experiment was conducted in order to confirm whether or not a PPAR δ agonist used in the present study, CMDD1111, passes through the placenta. CMDD 1111 was administered to 16-day pregnant mice at a concentration of 10 mg/kg, and then concentrations of the compound distributed in the bloods of mother animals and fetuses were analyzed for 24 hours. As a result, in the case of the mother animals, the maximum blood concentration (Cmax) thereof was 38 μM, the time for reaching the maximum blood concentration (Tmax) thereof was 1 hour, and the half-time (t1/2) thereof was 9 hours. In the case of the fetuses, the blood concentration thereof tended to increase with the time, unlike the mother animals, and the maximum blood concentration thereof was 8.9 μM. This concentration enables PPAR δ to sufficiently activate in the fetuses, and thus it was confirmed that the compound used in the present example passed through the placenta (
(2) Reprogramming of Fetal Mouse Through Administration of PPAR δ Agonist to Pregnant Mother (Maternal Treatment)
Fertile female mice and male mice were bred, and then pregnancy or not was checked by plug confirmation. CMDD1111 was orally administered to pregnant female mice at a concentration of 10 mg/kg once per day every day for six weeks (gestation and lactation periods). Side effects due to the administered material were not observed during the gestation period. The weight of a fetus group administered with vehicle during the gestation period was 1.33±0.11 g, and the weight of a fetus group administered with CMDD1111 was 1.37±0.09 g. The weight difference between the two groups was not shown (
The slow muscle fiber has a lot of myoglobin, which is oxygen transfer protein, and thus appears redder than the fast muscle. When the skin of the fetus was removed and the muscle thereof was observed, it may be seen that administered mice group had redder muscle (
The present invention conducted the gene expression analysis to establish the cause of the increase in slow muscle fiber generation in the mice subjected to fetal reprogramming by PPAR δ Activation.
(1) Gene Expression Analysis Using Microarray
As for an animal, the gastrocnemius muscle of 3-week old mice fetal-reprogrammed by PPAR δ agonist (CMDD1111) was resected, and then total RNA was extracted by using the Trizol reagent (Gibco). The isolated RNA was subjected to quantitative and purity verification processes, and then used for gene expression analysis using a Mouse 430 2.0 (Affimatrix) chip.
Generally, the slow muscle fiber has more mitochondria than the fast muscle fiber, increased fatty acid oxidation, and a low contraction rate. It was confirmed from analysis results that all of the gene expressions associated with the above three kinds of regulations were increased (
There were increases in expressions of enzymes necessary for fatty acid oxidation and mitochondrial respiration, such as pantothenate kinase 1 (PANK1: 2.4 fold), carnitine palmitoyl transferase 1a (CPT-1a: 1.4 fold), acyl CoA dehydrogenase (ACAD: 1.7 fold), acyl CoA synthetase (ACSL: 1.5 fold), cytochrome 8a (COX8A: 1.7 fold), ubiquinone (2.0 fold), and uncoupling protein 2, 3 (UCP2, 3: 1.5 fold, 2.3 fold).
There were increases in expressions of PPARγ coactivator 1a (1.7 folds), CamIIb (1.4 fold), CamIId (1.8 fold), and Mef2a (1.4 fold), which have been known to increase generation of slow muscle fibers, and there was a decrease in expression of HDAC4 (−1.5 fold) known as a negative regulator.
The slow muscle fiber has more calcium than the fast muscle fiber, and slow subtype calcium regulating proteins. Interestingly, as for the mice with increased slow muscle fibers according to the present invention, there were increases in expression of slow type calcium regulating proteins such as myosin binding protein C3 (MYBPC3: 2.8 fold), Troponin T2 (2.3 fold), Troponin I (3.2 fold), myosin heavy chain 6 (Myh6: 2.7 fold), and myosin light chain 7 (Myl7: 2.9 fold), and there were increases in expression cytosolic calcium concentration regulators, such as ryanodine receptor 2, 3 (RYR2, 3: 2.8 fold, 2.0 fold), ATPase, Ca2+ transporting (SERCA: 1.4 fold), and phospholamban (PLN: 2.8 fold).
(2) Gene Expression Analysis Using Real-Time PCR
A gene expression analysis experiment using the real-time PCR was conducted to further verify Miroarray analysis results. As for mouse group subjected to fetal reprogramming by administration of PPAR δ agonist (CMDD1111) during a muscular development period, there were increases in expression of core regulators for fatty acid oxidation and thermogenesis, such as carnitine palmitoyl transferase 1a (CPT-1a: 1.5 fold), uncoupling protein 3 (UCP3: 4.2 fold), acyl Co-A synthetase (ACSL: 1.4 fold), acyl Co-A dehydrogenase (ACAD10: 2.0 fold), and NDUFA12 (1.3 fold). In addition, there was a remarkable increase in expression of Adiponectin (ADIPOQ: 2.5 fold), which are commonly expressed in the slow muscle fiber and has been known to increase fatty acid oxidation to improve diabetes (
PGC-1α is a gene that is turned out to be a co-activator of fatty acid oxidation as well as a core regulator to increase mitochondria synthesis and slow muscle fiber generation. Expression of this gene was increased by 1.6 fold due to PPAR δ agonist (CMDD1111). In addition, expressions of CaMKII B and D, which have been known to increase fast-to-slow muscle fiber transformation during a muscular remodeling procedure, were also increased by 4.5 fold and 3.2 fold, respectively. Whereas, expression of HDAC4, previously known to suppress the slow muscle fiber generation through the loss of function study, was decreased by 0.6 fold (
As for the skeleton muscle, the concentration of cytosolic calcium is necessary for excitation-contraction coupling, and the concentration thereof itself is an important regulator of regulating muscle plasticity. In the present invention, the mice with increased slow muscle fibers had increased expressions of factors, known to regulate the cytosolic calcium in the myocytes. RYR2 and RYR3 are genes regulating calcium efflux in the sarcoplasmic membrane, and expressions thereof were increased by 2.2 fold and 3.6 fold, respectively, as compared with the control group. ATP2A2 is gene regulating calcium influx from the cytoplasm to the sarcoplasmic reticulum, and expression thereof was increased by 2.2 fold. Expression of phospholamban, which is a gene regulating activity of ATP2A2 and specific to slow muscle, was increased by 3.2 fold. Also, there were increases in expressions of TNNI3 (5.8 fold), MYH6 (6.8 fold), and My17 (4.8 fold), which are combined with calcium to thereby be involved in muscle contraction (
(3) Primary Cell Culture and Gene Expression Analysis
It was found from the microarray analysis and real-time PCR analysis that expressions of RYR3, ATP2A2, and PLN, which are core genes for regulating concentration of cytosolic calcium, were significantly increased for the mice subjected to fetal reprogramming by the PPAR δ agonist (CMDD1111). However, it has not been reported that the PPARs response element (PPRE) is present at promoters of these three genes. Therefore, the present inventors resected the muscle of the mouse with the removal of PPAR δ gene and conducted primary culture, in order to verify whether or not the increases in expressions of the above three genes are PPAR δ-dependent. After hind legs of a five-day-old fetus was resected, primary culture was conducted by the same method as developed by Rando (Rando et al, J. Cell. Biol., 1994, 125, 1275-1287). Myoblast, after being cultured, was transferred to a 6-well plate, and then differentiated into myotube while being treated with 300 nM of PPAR δ agonist (CMDD1111). The differentiated myotube was further treated with 300 nM of PPAR δ agonist (CMDD1111) for 2 days, and then total RNA was extracted by using a TRIzol reagent (Gibco). The extracted RNA was subjected to reverse transcription, to synthesize cDNA, which was then used as a template for real-time PCR analysis.
As the result of real-time PCR analysis, expressions of PDK4 and CPT-1, known to be directly regulated by PPAR δ, were increased by 2.2 fold and 1.5 fold, respectively. However, there was no change in PPAR δ-deficient cells. This means that expressions of PDK4 and CPT-1 are PPAR δ-dependently regulated. This tendency was also shown in the same manner for RYR (2.2 fold), PLN (1.7 fold), TNNI3 (1.7 fold), and ATP2A2 (4.3 fold), as can be seen in
(4) Verification on Cardiac Muscle Cell Regeneration Effect
As for the mouse group subjected to fetal reprogramming by PPAR δ agonist (CMDD1111), it was confirmed that expressions of genes such as RYR2, ATP2A2, and PLN, known to be commonly expressed in the heart muscle, were remarkably increased.
(5) Analysis of Cytosolic Calcium
An experiment using a calcium-specific dye reagent, Flou4(Molecular probe), was conducted in order to confirm the effect on concentration of cytosolic calcium by the changes of RYR, SERCA, and PLN. The experiment method is as follows. The isolated muscle cells were grown on a culture plate with an attached glass slide through primary culture, and then differentiated into myotube while being treated with 300 nM of PPAR δ agonist (CMDD1111). Flou4 (final concentration: 5 μM) dye reagent was put into the differentiated muscle cells, which were then cultured for 30 minutes. The calcium-free Kreb solution was used as a culture medium to measure the change of cytosolic calcium, and treatment with 10 mM of caffeine was conducted to activate calcium channels. Intracellular calcium ion change was measured by using a confocal microscope. As the measurement result, the retention time of cytosolic calcium was increased by 43% (592±60 versus 847±77 sec) in the muscle cell to which PPAR δ agonist (CMDD1111) was added (
The slow muscle fiber has great lipolytic capacity and has tolerance to fatigue due to exercise, and thus is appropriate in the exercise needing endurance. The present inventors conducted an experiment using a treadmill in order to measure an endurance increase effect of mice subjected to fetal reprogramming by PPAR δ agonist.
Before the experiment, mice were exercised for 5 minutes at a speed of 7 meters/min for two days so as to be adapted to exercising equipment. On day 3, the main experiment was conducted. As for the method for experiment, the mice were made to run at a speed of 10 meter/min for 60 minutes, and after that, the speed was increased at 1 meter/min once every 15 minutes until the maximum speed reaches 15 meters/min. As for the male mice, the running time was increased by 2.9 fold (235±26 versus 677±78 min, P<0.0001, n=6) and the running distance was increased by 3.0 fold (9927±1168 versus 3303±394 m, P<0.0001) in the PPAR δ agonist (CMDD1111)-administered mouse group than the control mouse group. As for the female mice, the running time was increased by 2.0 fold (376±19 versus 761±17 min, P<0.0001, n=4) and the running distance was also increased by 2.1 fold (5419±291 versus 11194±261 m, P<0.0001), which showed the same tendency as the results for the male mice (
RER is a ratio of the amount of CO2 exhaled to O2 inhaled in one breath. The RER is 1.0 when carbohydrate is mainly used for energy production, while the RER is 0.7 when fat is used. In the present invention, the slow muscle fibers of the mice subjected to fetal reprogramming was increasingly generated. The RER experiment using Oximax (Columbus) was conducted in order to evaluate whether or not this increase in slow muscle fiber generation actually influenced mouse energy metabolism. As a result, it may be seen that, the vehicle-administered mouse group had a smaller RER value than the PPAR δ agonist (CMDD1111)-administered mouse group, and thus used more fat than carbohydrate (
The present inventors checked a difference in lipid oxidation capacity between the two groups by using the following equations.
Carbohydrate oxidation=(4.51·RER−3.18)·VO2
Lipid oxidation=1.67·(1−RER)·VO2
As the calculation result, it may be seen that the mouse group to which PPAR δ agonist (CMDD1111) was administered during the fetal programming period used more lipid by average 44% (6.6 mg/kgmin vs. 9.5 mg/kgmin) but less carbohydrate by 20% (48 mg/kgmin vs. 38 mg/kgmin), as compared with the control group to which vehicle was administered. Therefore, it may be seen that the mice in which PPAR δ was activated during the fetal programming period had increased slow muscle fiber generation and thus increased the lipometabolism.
Even though the mice subjected to fetal reprogramming by PPAR δ according to the present invention were administered with the PPAR δ agonist compound only during the gestation and lactation periods, lipometabolitic capacity thereof was continuously increased even as adults. Lipometabolism has deep correlation with the occurrence of obesity and diabetes. Therefore, the present inventors checked the fetal reprogramming effect of PPAR δ on the occurrence of metabolic syndrome. The control group and administration group of 13-week old mice were fed with high-fat feedstuff (fat content: 35%) over a total of 84 days while being weighed once per week. As a result, it may be seen that, the body weight gain was suppressed by 8% in the mice subjected to fetal reprogramming by PPAR δ agonist compound (CMDD1111) as compared with the control group, as shown in
The present researchers conducted the glucose tolerance test (GTT) after the mice were fed with high-fat feedstuff for 17 weeks to induce diabetes. The experiment was conducted following the method proposed by Kelly, and challenged with over-night fasting in order to confirm the role thereof in the muscle. Glucose (1 mg/kg) was administered by using intraperitoneal injection, and then the blood glucose level change was measured for 2 hours. As a result, the fasting blood glucose level was lower, the maximum blood glucose concentration was lower, and the glucose clearance time was shorter in the mice of the administration group as compared with the mice of the control group (
An animal experiment was conducted in order to verify a memory improvement effect of the mice subjected to fetal reprogramming by PPAR δ agonist. Pregnant mice were orally administered with PPAR δ agonist, CMDD1111, at a concentration of 10 mg/kg/day during the gestation and lactation periods in order to verify effects of the invented material at the brain formation stage. When the fetus became an 8-week old adult, the Morris water maze test was conducted to compare memory between the control group and the administration group. This test can check special learning and memory, and is a task that is mainly dependent on the hippocampus in the brain. As the experiment result, the average times required to find the flatform were 26 seconds and 22 seconds (male and female, respectively) for the control group and were 9 seconds and seconds (male and female, respectively) for the administration group. Therefore, it was verified that the PPAR δ agonist improved memory during the fetal programming period, and this effect was maintained until the adulthood.
In order to complete the present invention, the fetal programming effects of PPAR δ agonists having different chemical structures from the above-mentioned CMDD111 was checked.
(1) Verification on Fetal Reprogramming Effect Using PPAR δ Agonist, CMDD1226
The Experiment using pregnant C57BL/6 mice was conducted in order to verify an endurance enhancement effect by fetal reprogramming of CMDD1226. The pregnant mice were administered with CMDD1226 at a concentration of 10 mg/kg/day every day during the gestation and lactation periods, and the endurances of the fetuses when being 7-week old adults were measured by using a treadmill. As a result, the group subjected to fetal reprogramming had a 1.9-fold increase in the running time and a 2.0-fold increase in the running distance as compared with the control group, and the endurance increase effect by the PPAR δ agonist was verified (
(2) Fetal Programming Using GW501516 (verification of effect and determination of optimum administration period)
The experiment for verifying the fetal reprogramming effect of GW501516 and determining the optimum administration period thereof was conducted. The experiment method was shown in
(3) Fetal Programming Using PPAR δ Agonist, CMDD1112 (Verification of Effect and Determination of Optimum Administration Concentration)
In order to verify a fetal reprogramming effect of CMDD1112 having superior selectivity to PPAR δ as compared with GW501516 and determine the optimum administration concentration of the PPAR δ agonist, the experiment was conducted by using four kinds of concentrations (1, 2, 5, mg/kg/day). As the experiment result, it was confirmed that the endurance enhancement effect was not exhibited at the concentrations of 1 and 2 mg/kg/day and the endurance was enhanced (running time: 1.4 fold, running distance: 1.5 fold) only at the concentration of 5 mg/kg/day (
In the present invention, as the result of animal fetal reprogramming by PPAR δ agonist, the experiment was conducted for three kinds of materials having different structures in order to check the endurance enhancement effect. The experiment results showed that all of the three kinds of PPAR δ agonists exhibited an endurance enhancement effect, and thus, the PPAR δ agonists can have effects of increasing slow muscle generation, enhancing endurance, preventing metabolic syndromes such as obesity, diabetes, arteriosclerosis, and fatty liver, and improving memory. As the experiment results using GW501516, superior effects may be confirmed when PPAR δ agonist was administered during both of the gestation and lactation periods. In addition, as the experiment results using CMDD1112, the effect was observed only at the concentration of 5 mg/kg/day or more in the procedure of fetal reprogramming. However, since all the agonists have different activation concentrations, materials having different structures can have lower activation concentrations.
It was confirmed that the fetal reprogramming method of PPAR δ developed by the present invention prevented/suppressed the occurrence of diabetes even in db/db mice having congenital diabetes due to genetic defects. The present researchers have checked the fetal reprogramming effect of PPAR δ by using a leptin receptor-deficient mouse (db/db). After hetero type female and male mice were bred, the PPAR δ agonist (CMDD1111) was administered to the female mice only during the lactation period. The glucose tolerance test (GTT) was conducted using only homo type male fetuses having induced diabetes through gene analysis and blood glucose analysis. As the result, the glucose tolerance was improved by fetal reprogramming of PPAR δ as shown in
As described above, the PPAR δ agonist can increase slow muscle fiber generation of the fetus, enhance endurance, in advance prevent metabolic diseases such as obesity, diabetes, arteriosclerosis, and fatty liver, and improve memory, by fetal reprogramming mammals including human beings.
In addition, the present invention developed a new PPAR δ agonist for mammal fetal reprogramming, and verified in vitro and in vivo effects of this material.
2. Development of PPAR δ Agonist
