| Outline of Final Research Achievements |
Methylation array analysis was performed using SSA/P samples and cancer in SSA/P samples, and we identified four genes(S100P, PKP3, MUC2, S100A2) as demethylation genes common to SSA/P. Each mRNA level was found to be increased by TaqMan PCR. Only Protein expression of S100P was markedly enhanced by immunostaining. We found that 30% of the promoter exist in exon 1 and intron 1 was demethylated. Knockdown experiments using siRNA of S100P gene were performed on the colon cancer cell line (HT29, WiDr) or SSA/P organoid culture cells, and cell proliferation and invasion ability were significantly suppressed in each cell.
