However, induction of autophagy by HDAC inhibitors was shown to have both pro-cell death and prosurvival functions in cancer cells . Further investigation into the modes of cell death would help in the Jul 22, 2010 · Two mechanistic explanations for PI-HDACi synergy. (A) HDAC inhibitors promote PI-induced proteotoxic stress. By blocking the proteasome, PIs promote the accumulation of damaged and misfolded proteins that are prone to aggregation, and it is this protein aggregation that serves as the primary cytotoxic stress, causing downstream reactive oxygen species (ROS) accumulation, JNK activation, and HDAC inhibitor cytotoxicity is NRF2-independent In the light of the finding that HDAC inhibitors increased NRF2 signalling and the expression of downstream genes, we tested whether NRF2 signalling affected the cytotoxicity of these compounds as single-use agents. HDAC inhibitor panobinostat and PI3K inhibitor pictilisib also decrease MYC mRNA levels, but are less potent than CUDC-907. To further dissect the role of CUDC-907 in MYC regulation, MYC gene was expressed under the control of CMV promoter medicated by lentivirus transduction in WSU DLCL2 cells to bypass regulations on the c-MYC promoter.
