In this project, the effect of loss of mitochondrial thioredoxin reductase (Txnrd2) on pancreatic carcinogenesis and pancreatic cancer cells was examined. We observed altered biology and higher levels of ROS, but no changes in mitochondrial respiration. Also, we observed a higher number of precursor lesions in KrasG12D; Txnrd2∆Panc mice, but a smaller number of invasive PDAC. This effect might be due to the lower activity of mutated RAS, perhaps caused by S-nitrosylation, as we also observed higher amount of NO signaling and eNOS activity in TXNRD2-deficient cell lines.
