G against Glioma: G protein inhibitory α subunit 2 (Gαi2) as a novel glioma target

Abstract

Glioma is among the cancers with the highest mortality and morbidity. The complex biology and acquired chemoresistance create a continuous need for novel, effective therapies. In a recent report by Wang et al, an elegant bioinformatic analysis revealed potential functions and underlying chemopreventive mechanisms involving G protein inhibitory α subunit 2 (Gαi2), which activates NF-κB, a master transcription factor in the regulation of glioma. Given that NF-κB takes part in positive regulatory feedback loops during glioma development, Gαi2 is an attractive candidate for targeted therapies. This discovery unlocks new avenues towards understanding the biology of gliomagenesis as well as the discovery of novel targeted antiglioma agents.
