The invention relates generally to the field of carotenoids, and methods of using the same, such as for treating skin-related conditions, including collagen loss.
Decline in skin biological structure and function caused by aging, attracts huge attention primarily due to the elevation in the population average life span. Fibroblasts are major components of the dermis and are known for producing collagen and elastic fibers. The hallmark of a photo aged skin is solar elastosis, which is probably an end product of extracellular matrix (ECM) degradation. The ECM that supports cells in skin tissues includes collagen, elastic fiber and fibrillin.
Neutrophils have been reported to infiltrate the skin following exposure to erythemogenic doses of ultra-violate B (UVB), is a solar simulating radiation (SSR), and a part of the natural sunlight. Exposure of human skin to a certain threshold of UV, infrared radiation, or heat, leads to neutrophils influx. These neutrophils are packed with potent proteolytic enzymes capable of degrading collagen, and elastic fibers. Neutrophil-derived proteolytic enzymes are involved in the ECM damage observed in several non-dermatological conditions. Furthermore, it was suggested that neutrophils, rather than keratinocytes and fibroblasts, may be the key players in photoaging. It was reported that following exposure of white skin to erythemogenic doses of SSR, infiltrating neutrophils and not keratinocytes or fibroblasts were the major sources of proteolytic enzymes (matrix metalloproteases (MMPs) and elastase, in particular). Oxygen-derived metabolites induce activation of proteolytic enzymes, and/or prevent these enzymes from being inactivated by antiproteinases, therefore induce ECM damage which may eventually result in solar elastosis.
There is still a great need for compositions and methods for preventing the release of neutrophil-derived proteolytic enzymes and therefore protect from collagen damage.

Dry ground golden tomato (Lycopersicon esculentum Mill. (Fam. Solanaceae) or Solanum lycopersicum) pulp was extracted under follow conditions: extraction type-supercritical CO2 extraction, pressure 360 bar, and a temperature of 60° C. The amount of the crude extract from the raw material was 2.7% (w/w).
A non-limiting example for the compounds identified within a supercritical-extracted golden tomato, including their relative amounts, are specified hereinbelow (Table 1). The total extract weight was 7.55 gr.
Standardized to 10% of total carotenoids GTE extract is called Lumenato. Comparison of the active ingredients between Lumenato, Lycoderm and Lyc-O-Mato 6% are presented in Table 2.
Blood was drawn from healthy volunteers. Neutrophils, at 95% purity were obtained by Ficoll-Hypaque centrifugation, dextran sedimentation, and hypotonic lysis of erythrocytes within 1 hour after blood was drawn. Cells were counted and their viability was determined by trypan blue exclusion.
Normal human dermal fibroblasts (NHFD) adult donor (PROMOCELL, Heidelberg, Germany), were cultured in fibroblast growth medium-2 (PROMOCELL) supplemented with fibroblast growth medium-2 (final supplemental concertation in the medium: Fetal calf serum 0.002% (v/v), basic fibroblast recombinant human growth factor 1 mg/ml, and recombinant human insulin 5 μg/ml), 2 mM L-glutamine; 100 U/ml penicillin; 100 μg/ml streptomycin (Beit-Haemek, Israel). The cells were maintained at 37° C. in humidified atmosphere containing with 5% CO2. NHDFs were seeded on 24-well plates when reached more than 80% confluency.
For immunofluorescence detection, NHFD were fixed with methanol at 20° C. for 3 min followed by wash in phosphate buffer saline (PBS). Fixed NHFDs were incubated with anti-collagen-3 antibodies (Santa Cruz) 1:50 in 5% (w/v) BSA/PBS for 90 min at room temperature. The cells were washed three times in PBS and incubated with Cy3 anti-mouse, (1:100 in 5% (w/v) BSA/PBS; Jackson ImmunoResearch Laboratories, Inc, PA, USA) for 60 min at room temperature. The cells were washed three times in PBS and the nuclei were stained with DAPI. Then final wash was performed, and the cells were analyzed using fluorescence microscopy (Olympus, BX60, Hamburg, Germany). Fluorescence intensity was determined for Collagen-3 using CellProfiler Program. The % of fluorescence area was determined using CellProfiler program.
Cytochrome C reduction—The production of the superoxide anion by neutrophils was measured as the superoxide dismutase inhibitable reduction of ferricytochrome c by the microtiter plate technique. Cells (2.5×105/well) were suspended in 100 μl Hanks' Balanced Salts Solution (HBSS) containing ferricytochrome c (150 mM). The reduction of acetyl ferricytochrome c was followed by the change of absorbance at 550 nm at 2-minute intervals on a Thermomax Microplate Reader (Molecular Devices, Melno Park, Calif.). The maximal rates of superoxide generation were determined and expressed as nanomoles O2−/106 cells/min using the extinction coefficient E550=21 mM−1·cm−1.
Amplex red—Horse Radish Peroxidase (HRP)-dependent oxidation of the highly sensitive fluorescent biosensor Amplex red was utilized. The oxidation of Amplex red occurs outside the cells by HRP, which traps H2O2 as soon as it is generated by spontaneous dismutation of O2−, the first product of NADPH oxidase. Resting and activated neutrophils (2×104/well) were suspended in KRPG buffer (phosphate buffer, 145 mM NaCl, 4.86 mM KCl, 1.22 mM MgSO4, 5.5 mM D-glucose, 0.54 mM CaCl2, pH 7.35) containing HRP (0.1 unit/ml) and Amplex red (50 μM). Fluorescence was recorded in a microplate reader with 535 nm excitation and 595 nm emission wavelengths. Background fluorescence was measured in the absence of microglial cells.
100 μl of 37° C. O-dianisidine hydrochloride solution (1 mg O-dianisidine, 10 ml phosphate buffer pH 6.0+0.0015% H2O2) were added to 100 μl supernatant in a 96-well plate immediately before the optical density was followed by the change of absorbance at 450 nm at 2 minute intervals on a Thermomax Microplate Reader (Molecular Devices, Melno Park, Calif.).
Tocopherol and phytosterol were added to 5×105 human neutrophils 20 min before addition of 100 ng/ml TNFα and maintained overnight at 37° C. in a humidified atmosphere containing 5% CO2. MPO activity was measured in the supernatant of the cultured neutrophils.
Zeta carotene, phytoene, tocopherol, phytosterol, or combinations thereof, were added to 5×105 human neutrophils 20 min before addition of 100 ng/ml TNFα and maintained overnight at 37° C. in humidified atmosphere containing 5% CO2. MPO activity was measured as escribed above.
Human MMP-9 concentrations in cell culture supernatants were quantified by ELISA kits (R&D systems Minneapolis, Minn., USA).
Human MMP-8 concentrations in cell culture supernatants were quantified by ELISA kits (OriGene, Technologies, Inc. Rockville, Md., USA).
N-methoxysuccinyl-ala-ala-pro-Val-P-nitroanilide was added to 100 μl of supernatant to reach a final concentration of 0.5 mM, and thereafter incubated overnight at 37° C. The absorbance at 405 nm was measured on a Thermomax Microplate Reader (Molecular Devices, Melno Park, Calif.).
Peritoneal macrophages were collected from the peritoneal cavity of 6-8 weeks old male ICR mice (Harlan, Israel) after an intraperitoneal injection of 1.5 ml of thioglycollate broth (4%) 4 days before harvest. Peritoneal macrophages were washed three times with PBS followed by hypotonic lysis of erythrocytes, yielding a highly enriched (90-95%) macrophage cell population. Macrophages were identified by FACS analysis using FITC-conjugated rat anti-mouse F4/80 (MCA497F) (Serotec, Oxford, England) by flow microfluorimetry on FACS (Becton Dickinson, Mountain View, Calif.). For each sample, 10,000 light scatter-gated viable cells were analyzed. Peritoneal macrophages (1×106 cells/well) were cultured in 96-well plates at 37° C. in 5% CO2 atmosphere in RPMI 1640 medium containing 10% FCS, 2 mM L-glutamine; 100 U/ml penicillin; 100 μg/ml streptomycin (Beit-Haemek, Israel). Cells were stimulated with 100 ng/ml LPS from Salmonella enterica serotype typhimurium in the absence or presence of the ingredients. LPS was purchased from Sigma, Israel.
All compounds were dissolved in DMSO, the volume of DMSO did not exceed 0.1-0.2% in the test plates. To the control plates appropriate volumes of DMSO (0.1-0.2%) were added. The % inhibition in each tube test was calculated in relation to its control.
NO levels in the supernatant of cell cultures were determined by assaying nitrite concentration using Griess reagent and sodium nitrite as a standard.
Cell viability was assessed by cell count using trypan blue exclusion or by the colorimetric MTT ([3-4, 5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium) metabolic activity assay. For MTT measurement cells were cultured in 96 well plates. MTT was dissolved in medium (5 mg/ml) and added to each sample in an amount equal to 10% of the culture medium volume. After incubation for 4 h, the formazan crystals were dissolved in 100 mM HCl, 10% Triton X-100 all in isopropanol in equal volume to culture medium, the medium only served as a background. Absorbance intensity measured by a Thermomax Microplate Reader (Molecular Devices, Melno Park, Calif., USA) at 570 nm with a reference wavelength of 690 nm.
Human pro-collagen-3 concentrations in cell-culture supernatants were quantified by a Human PIIINP (N-terminal pro-collagen III propeptide) ELISA kit (Elabscience Biotechnology Inc. Houston, Tex., USA). Since the concentration of pro-collagen-3 in the supernatants of the fibroblasts was very low, the supernatants were concentrated by evaporation.
Human collagen-3 concentrations in cell-culture lysates and supernatants were quantified by a human collagen, type III, alpha 1 (COL3A1) ELISA kit (Cusabio Technology Inc., Houston, Tex., USA).
Cells were incubated with Lumenato for 24 h and then hydrogen peroxide (H2O2) was added, and cells were incubated for additional 24 h to induce oxidative stress. The incubation medium was collected and the levels of collagen 1 a 1 protein secretion to the medium were analyzed using a specific ELISA detection kit.
Significant differences between evaluated parameters were determined by ANOVA using GraphPad Prism 5 (GraphPad Software Inc., San Diego, Calif., USA) followed by multiple comparisons Bonferroni post hoc correction. P value of less than 0.05 were considered statistically significant. Significance: *—p<0.05 , **—p<0.001, ***—p<0.0001.
In order to study the effect of GTE on the release of enzymes that have a potential to cause damage to collagen, the inventors first determined the kinetics of the release of such enzymes from activated neutrophils. Neutrophils were activated by 100 ng/ml TNFα or 100 ng/ml IL8 that are released from the skin cells during exposure to UV and activated. In addition, neutrophils were activated with 5×10−7 fMLP for comparison. As shown in
Neutrophils were activated by TNFα or IL8 for 4 hr and by fMLP for 30 min, in order to study the effect of GTE on the release of MMP-9 or MPO. GTE was added to the neutrophils for 10 min at 37° C. before activation. As shown in
Next, the effect of GTE on superoxide release from neutrophils was analyzed by cytochrome C reduction. The analysis was performed immediately after addition of each of the aforementioned agonists (e.g., TNFα, IL8, etc.) since superoxide is unstable. As shown in
In order to study the effect of GTE on the damage of collagen-3 induced by activated neutrophils the inventors used optimal conditions of cultured fibroblasts and of neutrophils. 1×105 fibroblasts were plated for 24 hr to obtain confluent cultures. Addition of 2×105 activated neutrophils induced a significant collagen-3 damage of about 30% but did not ruin the cultures, as shown by immune-fluoresce staining of collagen-3 (
Treatment of NHDF cells with 50 μM H2O2 resulted in about 10-fold reduction in collagen 1a1 secretion (
The amounts/levels of released degrading enzymes under the aforementioned coculture system, (as described in
Macrophages were stimulated with LPS and thereafter incubated with increased concentrations of either filtered pulp or GTE. As shown in
The inventors examined the effect of multiple phytonutrients on MPO activity in in stimulated neutrophils. The sole addition of tocopherol or phytosterol had no effect on the release and activity of MPO from neutrophils activated with TNFα (
The inventors also examined the effect of adding zeta carotene with either phytoene, a tocopherol, or a phytosterol, on MPO activity. The sole addition of zeta carotene, a tocopherol, phytoene, or a phytosterol had no inhibitory effect to 5% inhibition of MPO activity, at most (
The inventors have examined the bioavailability of carotenoids delivered within Lumenato capsules. The following carotenoids were quantified in the plasma at 1 week, 2 weeks, 3 weeks, and 4 weeks post administration. Phytoene, phytofluene and zeta-carotene which are the main carotenoids in Lumenato (the golden tomato extract) were absorbed well (
The inventors then examined whether Lumenato, the golden tomato extract, enhances skin resilience and prevents oxidative stress induced-skin damage in human keratinocytes. Reactive oxygen species (ROS) such as H2O2 are known to induce inflammatory processes in the skin, increase the production of matrix metalloproteinase (MMPs) in skin cells, leading to collagen degradation.
The inventors used hydrogen peroxide, H2O2, to induce oxidative stress in KERTr human keratinocytes, and analyzed the effects on cell number (cell death) and the secretion of MMP1. Cells viability was determined using the XTT cell proliferation kit, and MMP1 levels were measured by ELISA. Treatment of the cells with H2O2 led to a dose dependent cell death (
One possible explanation for the above-mentioned protective effect is the activation of the antioxidant response element transcription system (ARE/Nrf2). Thus, the inventors measured the activation of this transcriptional system using a reporter gene assay. A dose dependent activation of ARE/Nrf2 transcriptional activity by Lumenato was observed (
The inventors assembled a baseline skin questionnaire which included 14 questions asking the participants about their skin condition and appearance before and after taking the study product, Lumenato, (e.g., at baseline and after 12 weeks). The results show (Table 3) significant improvement in levels of satisfaction in 11 out of 14 questions, (excluding questions numbers 3, 10, and 11).
Further, the inventors assembled a skin update questionnaire which included 14 questions which asking the participants about their skin condition and appearance while they were taking the study product, Lumenato (Weeks 4, 8, and 12). The results show (Table 4) a significant improvement in levels of satisfaction in 10 out of 14 questions (excluding questions number 3, 8, 11, and 12).
While the present invention has been particularly described, persons skilled in the art will appreciate that many variations and modifications can be made. Therefore, the invention is not to be construed as restricted to the particularly described embodiments, and the scope and concept of the invention will be more readily understood by reference to the claims, which follow.
