Activation of mammalian target of rapamycin (mTOR) signaling pathway is associated with poor prognosis of epithelial ovarian cancer. The TSC1-TSC2 complex is a critical negative regulator of mTOR signaling. Here, we demonstrated that TSC1 was frequently downregulated in high-grade serous ovarian carcinoma (HGSOC) and low TSC1 expression level is associated with advanced tumor stage. We next identified miR-130a to be a negative regulator of TSC1 by targeting its 3'UTR. miR-130a was overexpressed in HGSOC and could drive proliferation and invasion/metastasis of ovarian cancer cells. miR-130a could also attenuate rapamycin/starvation-induced autophagy. Ectopic TSC1 expression could block the effects of miR-130a on cell proliferation, migration and autophagy. Finally, we found that miR-130a expression could be upregulated by inflammatory factors and was transactivated by NF-κB. Therefore, our findings establish a crosstalk between inflammation and mTOR signaling that is mediated by miR-130a, which might have a pivotal role in the initiation and progression of HGSOC.
