Summary: High-grade serous ovarian cancer (HGSOC) is the most common and aggressive type of ovarian cancer. It is often diagnosed at a late stage and eventually becomes resistant to standard chemotherapy. The mechanistic target of rapamycin (mTOR) is a key regulator of cellular functions including growth, survival, immune responses, and metabolism. To show how the mTOR pathway becomes dysregulated in HGSOC, we analysed gene expression data and microRNA patterns from both ovarian cancer patients and healthy individuals. We found that many of the genes involved in the mTOR pathway are unusually dysregulated. A group of regulatory molecules, the let-7 miRNAs, may allow this abnormal activity to continue. We also discovered a distinct pattern where one part of the pathway (mTORC1) is switched on while another (mTORC2) is switched off. These findings may help guide more effective, targeted treatments in the future targeting these pathways.
