Humans express two types of GA isoforms: GLS and GLS2. GLS isozymeshave been consistently related to cell proliferation, but the role of GLS2 in cancer remains poorlyunderstood. GLS2 is repressed in many tumor cells and a better understanding of its function intumorigenesis may further the development of new therapeutic approaches. We analyzed GLS2expression in HCC, GBM and neuroblastoma cells, as well as in monkey COS-7 cells. We studied GLS2expression after induction of differentiation with phorbol ester (PMA) and transduction with the fulllengthcDNA of GLS2. In parallel, we investigated cell cycle progression and levels of p53, p21 and c-Mycproteins. Using the baculovirus system, human GLS2 protein was overexpressed, purified and analyzedfor posttranslational modifications employing a proteomics LC-MS/MS platform. We have demonstrateda dual targeting of GLS2 in human cancer cells.
