Here we show that low dose Oxali, and to a lesser extent other platinoids, can uniquely activate the transcriptional program that controls MHCI antigen processing and presentation. Activation of this program correlates with induction of histone acetylation and enhanced chromatin accessibility. Oxaliplatin also induces NF-kB dependent IFNg receptor 2 (IFNgR2) thereby augmenting the tumor response to exogenous IFNg produced by reinvigorated effector CD8+ T cells. Overall design: RNA were isolated after 24h treatment of prostate cancer cell lines Myc-Cap and TRAMP-C2 with Oxaliplatin and Cisplatin at 2uM or 20uM dosages.
