Abstract
- Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and metabolic abnormality disease that mainly affects women of reproductive age. LINC00173, a novel long noncoding RNA (lncRNA), has emerged as an important factor in the development of PCOS. However, the role of LINC00173 in PCOS development and its specific upstream and downstream mechanisms remain to be further clarified. Here, we found that LINC00173 was significantly upregulated in granulosa cells (GCs) of PCOS patients, and played a crucial role in promoting apoptosis of GCs. Mechanistically, we observed the activation of endoplasmic reticulum (ER) stress in the GCs of PCOS patients, and the ER stress sensor ATF4 could directly induce LINC00173 expression by binding to its promoter. LINC00173 further upregulated the expression of Harakiri (HRK) and subsequently inhibited downstream PI3K/AKT pathway. In conclusions, our study uncovered that ER stress-induced upregulation of LINC00173 leads to increased HRK expression and inhibition of the PI3K/AKT pathway, thereby promoting the progression of PCOS. These findings provide a new therapeutic strategy for the treatment of PCOS. [ABSTRACT FROM AUTHOR]
