DNA Methylation

DNA methylation is a form of chemical modification of DNA, which can change genetic performance under no change of DNA sequence. Many studies have shown that DNA methylation can cause changes in chromatin structure, DNA conformation, DNA stability and the way DNA interacts with protein, thereby regulating gene expression.

DNA methylation is one of the earliest discovered and most deeply studied epigenetic regulatory mechanisms. Broadly speaking, DNA methylation refers to the chemical modification process in which a specific base in the DNA sequence is modified with a methyl by covalent bonding with S-adenosyl methionine (SAM) as methyl donor under the catalysis of DNA methyltransferase (DNMT). This DNA methylation can occur at position C-5 of cytosine, position N-6 of adenine and position N-7 of guanine. DNA methylation in general studies mainly refers to the methylation process that occurs at the carbon atom of position C-5 on cytosine in CpG dinucleotides, the product is called 5-methylcytosine (5-mC). The 5-methylcytosine (5-mC) is the main form of DNA methylation in eukaryotic organisms such as plants and animals. DNA methylation, as a relatively stable modification state, can be passed on to new generations of DNA during DNA replication process under the action of DNA methyltransferase, which is an important epigenetic mechanism.

There are two types of DNA methylation reactions. One type is that the two unmethylated strands in the DNA are methylated, which is called denovo methylation; the other type is that the unmethylated strand of double-stranded DNA with one methylated strand and one unmethylated strand is methylated, which is called maintenance methylation.

Typically, DNA methylation is the methylation of DNA CpG site. The distribution of CpG binucleotide is very uneven in the human genome, while CpG remains or is higher than normal level in some regions of the genome. The CpG site rich region (also known as CpG island) is mainly located in the promoter region and exon regions of the gene, which is a region rich in CpG dinucleotide. About 60% of the promoters of the gene contains CpG island. The CpG is the abbreviation of cytosine (C)-phosphate (p)-guanine (G).

Gene expression is regulated by various signaling pathways, transcription factors and epigenetic modifications in the cell. DNA methylation modification is an important way in which epigenetic modifications regulate gene expression. The level of DNA methylation in a specific gene region often affects the expression level of the gene. Compared to the regulation of gene expression by signal transduction pathways and transcription factors, the effect of DNA methylation modification on gene expression is more stable in epigenetic modification, which is not easily affected by the extracellular environment. DNA methylation modification can be easily and accurately detected using existing technologies, so the DNA methylation is an ideal biomarker.

Example 181

The promoter region of NNMT gene, the region from 1050 bp before the transcription start site to 499 bp after the transcription start site in NNMT gene and the region from 1050 bp to 193 bp before the transcription start site in NNMT gene were subjected to bisulfite sequencing to measure methylation level of DNA CpG site in four tumor cell lines (NCI-H82, G-401, MDA-MB-453 and SW48) sensitive to the compounds prepared in the Examples of the present invention and four tumor cell lines (786-0, CFPAC-1, GB-1 and SF126) insensitive to the compounds prepared in the Examples of the present invention. Firstly, genomic DNA was subjected to bisulfite, unmethylated cytosine was determined to form uracil, and methylated cytosine could not be determined, so the methylation sites could be determined by comparing the sequencing samples treated with bisulfite to the sequencing samples treated without bisulfite, and the result was shown in FIG. 4, FIG. 5, and FIG. 6.

As shown in FIG. 4 (the promoter region of NNMT gene), FIG. 5 (the region from 1050 bp before the transcription start site to 499 bp after the transcription start site in NNMT gene) and FIG. 6 (the region from 1050 bp to 193 bp before the transcription start site in NNMT gene), the compounds prepared in the Examples of the present invention had significantly stronger inhibitory effect on tumor cells with high methylation level of DNA CpG site in the promoter region of NNMT gene, the region from 1050 bp before the transcription start site to 499 bp after the transcription start site in NNMT gene and the region from 1050 bp to 193 bp before the transcription start site in NNMT gene, while the compounds prepared in the Examples of the present invention had significantly weaker inhibitory effect on tumor cells with low methylation level of DNA CpG site in the promoter region of NNMT gene, the region from 1050 bp before the transcription start site to 499 bp after the transcription start site in NNMT gene and the region from 1050 bp to 193 bp before the transcription start site in NNMT gene, indicating the methylation level of DNA CpG site in the promoter region of NNMT gene, the region from 1050 bp before the transcription start site to 499 bp after the transcription start site in NNMT gene and the region from 1050 bp to 193 bp before the transcription start site in NNMT gene was positively correlated with the sensitivity of tumor cell to the compounds prepared in the Examples of the present invention.

Example 182

The methylation of specific DNA CpG sites from 840 bp (i.e., site 114165695 on human chromosome 11) to 469 bp (i.e., site 114166066 on human chromosome 11) before the transcription start site in NNMT gene in three tumor cell lines (NCI-H82, G-401 and SW48) sensitive to the compounds prepared in the Examples of the present invention and three tumor cell lines (786-0, CFPAC-1 and SF126) insensitive to the compounds prepared in the Examples of the present invention was studied.

Firstly, genomic DNA was subjected to bisulfite, unmethylated cytosine was determined to form uracil, and methylated cytosine could not be determined, so the methylation sites could be determined by comparing the sequencing samples treated with bisulfite to the sequencing samples treated without bisulfite, then PCR amplification and sequencing analysis were performed on the region using corresponding primers to measure the methylation level of CpG site in the DNA region.

The study showed that almost all of the seven CpG sites (site 114165695, site 114165730, site 114165769, site 114165804, site 114165938, site 114166050 and site 114166066 on the human chromosome 11) were methylated in cell lines (NCI-H82, G-401 and SW48) sensitive to the compounds prepared in the Examples of the present invention, while none of the above seven CpG sites were methylated in cell lines ((786-0, CFPAC-1 and SF126) insensitive to the compounds prepared in the Examples of the present invention, the methylation of related sites was shown in FIG. 7.

Example 183

The methylation level of DNA in cell was maintained by DNA methylation enzymes DNMT3a, DNMT3b and DNMT1. The original methylation of DNA was performed with DNMT3a and DNMT3b, DNMT1 could replicate and maintain methylated DNA with the help of protein UHRF1 (ubiquitin-like with PHD and ring finger domain 1). The correlation between the expression of NNMT and the expression of DNMT1, UHRF1, DNMT3a and DNMT3b in tumor was determined in the Example.

Experiment Method and Result:

The expression of NNMT gene, DNMT1, UHRF1, DNMT3a and DNMT3b in various cells were obtained from a public database (Cancer Cell Line Encyclopedia, CCLE, 1019 cells in total). Then, the correlation between expression of NNMT and the expression of DNMT1, UHRF1, DNMT3a and DNMT3b in these cells was analyzed using bioinformatics, and the correlation between the expression level ofNNMT gene and the expression level of DNMT1, UHRF1, DNMT3a and DNMT3b in each cell was analyzed, the experiment result was shown in FIG. 8.

The FIG. 8 showed the expression of NNMT was negatively correlated with the expression of DNA methylase and UHRF1 in each cell.

Example 184

The activity of mitochondria permeability transition pore in related cell was investigated.

Experimental Background:

The mitochondria permeability transition pore (mPTP) was a non-specific channel on the inner membrane of mitochondria, which could allow small molecules with molecular less than 1.5 KD to pass freely, and its activity was affected by peroxides (such as H₂O₂), pH and calcium ions in mitochondria. Some cells had active mitochondria permeability transition pore, while some cells had inactive mitochondria permeability transition pore. For cells with active mitochondria permeability transition pore, adding peroxide (such as H₂O₂) could increase the activity of mitochondria permeability transition pore, resulting in a decrease in mitochondria membrane potential. For cells with inactive mitochondria permeability transition pore, adding peroxide (such as H₂O₂) had no significant effect on the activity of the mitochondria permeability transition pore, and the mitochondria membrane potential had no significant change. Based on this principle, whether the mPTP was active or inactive in specific cell could be determined by measuring the change of potential difference of the mitochondria membrane under peroxide stimulation

Experimental Method and Result:

Daoy cell (human medulloblastoma cell, ATCC no. HTB-186) were cultured in 10% fetal bovine serum-containing DMEM (+p/s), and then 1.5 μM Cyclosporin A (CSA, CSA could effectively inhibit the activity of mitochondria permeability transition pore) was added to the medium, and the cell cultured in medium without the addition of CsA were used as blank control.

The mitochondria membrane potential difference was detected by Tetramethylrhodamine (TMRM), the high fluorescence intensity of TMRM represented the high membrane potential difference, the result was shown in Table 4.

TABLE 4
Relative TMRM signal intensity (%) in
Daoy cell after different treatments
	Cell	Daoy cell
	CsA	−	−	+	+
	H2O2	−	+	−	+
	mean value	100	82	125	121
	Standard deviation	7	11	14	11
	Repeat times	3	3	3	3
	P value		<0.05	<0.01
	Remarks:
	“+” represented existence,
	“−” represented none.

It could be seen from Table 4 that as or normal Daoy cell cultured in medium without the addition of CSA, the membrane potential was significantly down-regulated under the action of H₂O₂, indicating that the mitochondria permeability transition pore was active in Daoy cell. However, as for normal Daoy cell cultured in medium with the addition of CSA (CsA could inhibit the activity of mitochondria permeability transition pore (mPTP)), the membrane potential was not down-regulated under the action of H₂O₂, indicating that active mPTP of Daoy cell was inhibited by CsA and the mPTP of Daoy cell become inactive, H₂O₂ did not cause a decrease in membrane potential in this case.

Therefore, Table 4 showed that the mitochondria permeability transition pore (mPTP) was active in Daoy cell.

Example 185

The inhibitory effect of the compounds prepared in the Examples of the present invention on the mPTP-active Daoy cell, and the mPTP-inactive Daoy cell which was constructed by transfecting the Daoy cell with shRNA that specifically induce the degradation of PPIF mRNA.

The peptidyl-prolyl cis-trans isomerase F was abbreviated as PPIF, the protein identification number was UniProtKB/Swiss Prot: R30405, and the gene identification number was NCBI Entrez Gene: 10105

1. Construction of Daoy Cell Having Inactive Mitochondria Permeability Transition Pore (mPTP)

1.1 Experimental Background:

The activity of mitochondria permeability transition pore (mPTP) was regulated by the PPIF protein. When PPIF protein was inhibited, mPTP activity was significantly decreased. PPIF protein activity was restricted by the expression level of PPIF protein in cell. The PPIF protein expression level in Daoy cell can be specifically decreased by transfecting the Daoy cell with shRNA that could specifically induce the degradation of PPIF mRNA, thereby constructing Daoy cell having inactive mitochondria permeability transition pore (mPTP) (abbreviated as mPTP-inactive Daoy cell).

1.2 Experiment Method and Result:

A viral vector carrying shRNA that could specifically induces the degradation of PPIF mRNA was obtained using cloning technology, the shRNA (the nucleotide sequence was GTTCTTCATCTGCACCATAAA (SEQ ID NO: 2)) carried by viral vector could specifically induce the degradation of PPIF mRNA, the Daoy cell was transfected with the viral vector carrying shRNA that could specifically induce the degradation of PPIF mRNA, and the Daoy cell transfected with empty virus vector without carrying shRNA that can specifically induce the degradation of PPIF mRNA was used as control. The expression level of PPIF protein in Daoy cell was detected using Western blot technique, and the result was shown in FIG. 9. The FIG. 9 showed the PPIF in the Daoy cell transfected with the shRNA that could specifically induce the degradation of PPIF (mPTP regulated protein) mRNA was not expressed (i.e. PPIF shRNA in FIG. 9), while the PPIF in the Daoy cell not transfected with the shRNA that could specifically induce the degradation of PPIF mRN was normally expressed (i.e. con shRNA in FIG. 9, as the control). The activity of mitochondria permeability transition pore was detected in the Daoy cell transfected with empty virus vector without carrying shRNA that could specifically induce the degradation of PPIF mRNA and the Daoy cell transfected with virus vector carrying shRNA that could specifically induce the degradation of PPIF mRNA was detected, and the mitochondria membrane potential difference was detected by Tetramethylrhodamine (TMRM) according to the method described in Example 184 above, the high fluorescence intensity of TMRM represented the high membrane potential difference, the results were shown in Table 5 and Table 6.

The mPTP-active Daoy cell refered to the Daoy cell transfected with empty virus vector without carrying shRNA that can specificly induce the degradation of PPIF mRNA; the mPTP-inactive Daoy cell refered to the Daoy cell transfected with virus vector carrying shRNA that can specificly induce the degradation of PPIF mRNA.

As was shown in Table 7, the compounds prepared in the Examples of the present invention had significant inhibitory effect on mPTP-inactive Daoy cell, while the compounds prepared in the Examples of the present invention had weaker inhibitory effect on mPTP-active Daoy cell. Decreasing the mPTP activity in Daoy cell could significantly improve the inhibitory effect of the compounds prepared in the Examples of the present invention on tumor, therefore, the compounds prepared in the Examples of the present invention had more significant inhibitory effect on mPTP-inactive Daoy cell, the mPTP-inactive Daoy cell was highly sensitive to the compounds prepared in the Examples of the present invention. Therefore, the compounds prepared in the Examples of the present invention had excellent precision treatment effect on mPTP-inactive Daoy cell. As mentioned above, when PPIF protein was inhibited, mPTP activity was significantly decreased, inhibiting the expression level of PPIF protein could decrease the mPTP activity in Daoy cell. Therefore, the compounds prepared in the Examples of the present invention had more significant inhibitory effect on Daoy cell with low expression of PPIF protein, while the compounds prepared in the Examples of the present invention had weaker inhibitory effect on Daoy cell with normal expression of PPIF protein, indicating that decreasing the expression level of PPIF protein could significantly improve the inhibitory effect of the compounds prepared in the Examples of the present invention on tumor. Therefore, the compounds prepared in the Examples of the present invention had more significant inhibitory effect on Daoy cell with low expression of PPIF protein, i.e, the Daoy cell with low expression of PPIF protein was more sensitive to the compounds prepared in the Examples of the present invention compared with the Daoy cell with normal expression of PPIF protein. The compounds prepared in the Example of the present invention had excellent precision treatment on Daoy cell with low expression of PPIF protein.
