Objective
This study aims to investigate the expression of long noncoding RNA CTBP1-AS in patients with polycystic ovarian syndrome (PCOS) and its effects on the proliferation and autophagy of ovarian granulosa cells.
Methods
Real-time polymerase chain reaction assay was used to analyze the expression levels of CTBP1-AS in peripheral blood leukocytes of 40 PCOS patients and 40 non-PCOS women and the CTBP1-AS expression in ovarian granulosa cells and transfect ovarian granulosa cells with pcDNA3.1-CTBP1-AS and si-CTBP1-AS, respectively. Consequently, the CCK-8 kit was used to analyze the effect of CTBP1-AS on the proliferation of ovarian granulosa cells. Moreover, Western blotting was used to detect the expression levels of autophagy-related proteins LC3II/I and P62.
Result
The CTBP1-AS expression in the peripheral blood of PCOS patients was higher compared with non-PCOS patients (P < 0.05). Furthermore, the CTBP1-AS expression of ovarian granulosa cells in PCOS patients was higher compared with non-PCOS patients (P < 0.05). Consequently, CTBP1-AS overexpression in ovarian granulosa cells promotes the proliferation of ovarian granulosa cells and autophagy levels (P < 0.05). The CTBP1-AS expression interference in ovarian granulosa cells can inhibit the proliferation of ovarian granulosa cells and autophagy levels (P < 0.05).
Conclusion
The CTBP1-AS expression in peripheral blood and ovarian granulosa cells of PCOS patients significantly increased, and CTBP1-AS could promote the proliferation of ovarian granulosa cells and the level of autophagy.
