卵巢癌细胞中OY-TES-1基因启动子CpG位点甲基化状态分析
CpG site methylation analysis of OY-TES-1 promoter in ovarian cancer cell
摘要
Abstract
Objective-. To investigate CpG site methylation of OY-TES-1 promoter in ovarian cancer cell line SKOV3. Methods-. OY-TES-1 expression in SKOV3 was detected by immunocytochemical staining with anti-OY-TES-1 antibody. The DNA fragment ( -127 bp'-hllO bp, including 24 CpG sites) of 5' flanking of OY-TES-1 gene was amplified from the ge-nomic DNA extracted from SKOV3 by bisulfite sequencing PCR (BSP). CpG site methylation of OY-TES-1 promoter was compared with testis. Results-. Positive expression of OY-TES-1 protein was found in SKOV3. Methylation percentage of 24 CpG sites on OY-TES-1 promoter tested was 80. 21% in SKOV3, which was higher than that in normal testis tissues. Conclusion-. OY-TES-1 has hypermethylated promoter CpG sites in SKOV3. Further study needs to learn the effect of these CpG sites methylation on the expression of OY-TES-1 when using DNA methyltransferase inhibitor 5-aza-2 -deoxycytidine (DAC).关键词
