Recently, autophagy has emerged as a critical process in the control of T-cell homeostasis. Given the pivotal role of NF-kappaB in the signaling events of T cells, we have analyzed and unveiled a conserved NF-kappaB binding site in the promoter of the murine and human BECN1 autophagic gene (Atg6). Accordingly, we demonstrate that the NF-kappaB family member(More)
A number of different kinases have been implicated in NF-kappa B regulation and survival function. Here we investigated the molecular cross-talk between glycogen synthase kinase-3 beta (GSK-3 beta) and the p105 precursor of the NF-kappa B p50 subunit. GSK-3 beta forms an in vivo complex with and specifically phosphorylates NF-kappa B1/p105 at Ser-903 and(More)
Senescence represents an important barrier against cellular transformation. Here we show that CAPNS1 depletion impairs senescence induction both in BJ-ET H-Ras(v12) inducible human fibroblasts upon Ras induction and in HT1080 targeted to senescence by treatment with low doses of doxorubicin. We further show that CAPNS1 depletion is coupled to reduced levels(More)
Ubiquitously expressed micro- and m-calpain proteases consist of 80-kDa catalytic subunits encoded by the Capn1 and Capn2 genes, respectively, and a common 28-kDa regulatory subunit encoded by the calpain small 1 (Capns1) gene. The micro- and m-calpain proteases have been implicated in both pro- or anti-apoptotic functions. We have found that Capns1(More)
