Outline of Final Research Achievements

Cell proliferation by addition of vitamin A and vitamin D to ovarian clear cell adenocarcinoma 4 strains showed cytostatic effect in OVISE, OVTOKO and TOV - 21G cell lines. It was thought that vitamin A and vitamin D receptor were bound and transcription of telomerase was suppressed, and cell proliferation inhibitory effect was seen. On the other hand, cell proliferation inhibitory effect was not observed in ES-2 cell line. Since ES-2 is a cell line with a mutation in the TERT promoter [-129 to -154 bp] region, it was thought that the inhibition of vitamin A, D was canceled and transcription of telomerase was enhanced. In addition, chromatin immunoprecipitation was performed using the TOV-21 G cell line, which is without TERT promoter mutation, and it was confirmed that the RARα antibody binds to the TERT promoter region. The [-129 to -154 bp] region was shown to have a binding site for the vitamin A receptor.
