PTEN and neoplasm: In this study, after confirming our earlier findings, we investigated the downstream mechanisms of the PTEN/PKM2/ERα/Glo1/MG-H1 axis in controlling PC3 cell growth, focusing on the role of RAGE, a high-affinity receptor for MG-H1; hydrogen peroxide (H2O2); and Krev interaction trapped 1 (KRIT1), an emerging tumor suppressor.
