Abstract Cancer homeostasis depends on a balance between activated oncogenic pathways driving tumorigenesis and engagement of stress response programs that counteract the inherent toxicity such aberrant signaling. Although inhibition signaling has been explored extensively, there is increasing evidence overactivation same can also disrupt cancer cause lethality. We show here protein phosphatase 2A (PP2A) hyperactivates multiple engages responses in colon cells. Genetic compound screens...
Abstract Current therapy against colorectal cancer (CRC) is based on DNA-damaging agents that remain ineffective in a proportion of patients. Whether and how non-curative DNA damage-based treatment affects tumor cell behavior patient outcome primarily unstudied. Using CRC patient-derived organoids (PDO)s, we show sublethal doses chemotherapy (CT) does not select previously resistant populations but induces quiescent state specifically to TP53 wildtype (WT) cells, which linked the acquisition...
The DNA damage repair kinase ATM is phosphorylated by the NF-κB pathway IKKα, resulting in enhanced through nonhomologous end-joining pathway. Thus, inhibition of IKKα enhances efficacy cancer therapy based on inducing damage. Here, we found a role for IKK regulatory subunit NEMO mediated and IKKα. Exposure to damaging agents induced interaction with preformed ATM-IKKα complex, which was required target active chromatin efficient but not activating ATM. Recognition damaged IKKα-NEMO-ATM...
Maintenance of pluripotency is a multifactorial process in which NF-κB negative regulator. Our previous work identified chromatin role for IκBα, the master regulator signaling, that critical proper regulation various tissue stem cells. Here, we found IκBα accumulates specifically fraction pluripotent embryonic depletion does not affect NF-kB-dependent transcription, but causes profound epigenetic rewiring cells, including alterations H3K27me3, histone mark catalyzed by Polycomb repression...

Abstract We previously demonstrated that the NF-κB inhibitor IκBα binds chromatin together with PRC2 to regulate a subset of developmental- and stem cell-related genes. This alternative function has been elusive in both physiological disease conditions because predominant role as negative regulator NF-κB. here uniquely characterize specific residues allow generation separation-of-function (SOF) mutants are defective for either NF-κB-related (SOF ΔNF-κB ) or chromatin-related ΔH2A,H4...
