Long Non-Coding RNA X Inactive Specific Transcript Suppressed the Proliferation and Invasion of Ovarian Cancer Cells by Restricting the Expression of Staphylococcal Nuclease Domain Containing 1
Ovarian cancer is one kind of a deadly gynecological malignancy. Recent study has shown that SND1 was associated with the development of ovarian cancer. Furthermore, the expression of lncRNA XIST in ovarian cancer was down-regulated. However, it is unclear whether lncRNA XIST could affect the occurrence and development of ovarian cancer by targeting SND1. In this study, we used the lentivirus to establish the overexpression and knockdown SND1 ovarian cancer cells. And we next detected the proliferation and invasion of these cells in diverse groups. Then, the luciferase assays were performed to detect the targeted effect of lncRNA XIST on SND1 and determined the expression of SND1 in the overexpressed lncRNA XIST ovarian cancer cells. We found that SND1 promoted the proliferation and invasion of ovarian cancer cells. And the lncRNA XIST targeted and suppressed the expression of SND1. Overexpression of lncRNA XIST inhibited the proliferation and invasion of ovarian cancer cells. However, the overexpression of SND1 alleviated the inhibitory efficacy of lncRNA XIST on the proliferation and invasion of ovarian cancer cells. LncRNA XIST inhibited the proliferation and invasion of ovarian cancer by suppressing the expression of SND1.
