摘要
Glioblastoma(GBM) is one of the most lethal human cancers. Genomic analyses define the molecular architecture of GBM and highlight a central function for mechanistic target of rapamycin(m TOR) signaling. m TOR kinase exists in two multiprotein complexes, namely, m TORC1 and m TORC2. These complexes differ in terms of function, regulation and rapamycin sensitivity. m TORC1 is well established as a cancer drug target, whereas the functions of m TORC2 in cancer, including GBM, remains poorly understood. This study reviews the recent findings that demonstrate a central function of m TORC2 in regulating tumor growth, metabolic reprogramming, and targeted therapy resistance in GBM, which makes m TORC2 as a critical GBM drug target.
Glioblastoma （GBM） is one of the most lethal human cancers. Genomic analyses define the molecular architecture of GBM and highlight a central function for mechanistic target of rapamycin （roTOR） signaling, roTOR kinase exists in two multi- protein complexes, namely, mTORC 1 and mTORC2. These complexes differ in terms of function, regulation and rapamycin sensitivity, mTORC 1 is well established as a cancer drug target, whereas the functions of mTORC2 in cancer, including GBM, remains poorly understood. This study reviews the recent findings that demonstrate a central function ofmTORC2 in regulating tumor growth, metabolic reprogramming, and targeted therapy resistance in GBM, which makes mTORCZ as a critical GBM drug target.
