Proteasome inhibition alters glutamine metabolism. (A) Relative mRNA expression levels of MYC, GLS and GLS2 in a panel of HLRCC specimens; (B) Relative mRNA expression levels of MYC, GLS and GLS2 in UOK262 after 24 hours treatment with bortezomib, marizomib and carfilzomib (30 nM); (C) Venn diagrams of the effects of the proteasome inhibitors and siMYC measured by Nanostring-based mRNA expression of 180 metabolic genes. Bort: bortezomib; Mar: marizomib; Carf: carfilzomib; CTL: DMSO control.
