Immune checkpoint inhibitors have not been effective for immunologically “cold” tumors, such as prostate cancer, which contain scarce tumor infiltrating lymphocytes. We hypothesized that select tissue-specific and immunostimulatory bacteria can potentiate these immunotherapies. Here we show that a patient-derived prostate-specific microbe, CP1, in combination with anti-PD-1 immunotherapy, increased survival and...
Post-transcriptional gene silencing (PTGS) and, more specifically, RNA interference (RNAi) include the processes by which a small double-stranded RNA, 19 to 22 nucleotides (nts) long, negatively regulates the expression and/or translatability of a target RNA, which harbors reverse complementarity to that small RNA, by recruiting the so-called RNA-Induced Silencing Complex...
SIRT3 is a mitochondrial-localized, NAD+-dependent deacetylase, tumor suppressor protein that functions to direct mitochondrial energy sensing and antioxidant proteins, increasing the efficiency of energy utilization, providing a redox balanced environment, and preventing aging-related diseases. One SIRT3 deacetylation target is NADP+-dependent isocitrate dehydrogenase 2 (IDH2), a key Krebs Cycle enzyme that...
