mTORC2/AKT/HSF1/HuR constitute a feed-forward loop regulating Rictor expression and tumor growth in glioblastoma

Overexpression of Rictor has been demonstrated to result in increased mechanistic target of rapamycin C2 (mTORC2) nucleation and activity leading to tumor growth and increased invasive characteristics in glioblastoma multiforme (GBM). However, the mechanisms regulating Rictor expression in these tumors is not clearly understood. In this report, we demonstrate that Rictor is regulated at the level of mRNA translation via heat-shock transcription...
