Innate immune responses are critically dependent on MAPK (mitogen-activated protein kinase) signalling pathways, in particular JNK (c-Jun N-terminal kinase) and p38 MAPK. Both of these kinases are negatively regulated via their dephosphorylation by DUSP1 (dual--specificity phosphatase 1). Several pro- and anti-inflammatory stimuli converge to regulate the(More)
Intrachain disulfide bond formation among the cysteine thiols of SNAP-25, a component of the SNARE protein complex required for neurotransmitter release, has been hypothesized to link oxidative stress and inhibition of synaptic transmission. However, neither the availability in vivo of SNAP-25 thiols, which are known targets of S-palmitoylation, nor the(More)
Chromatin factors have emerged as the most frequently dysregulated family of proteins in cancer. We have previously identified the histone deacetylase SIRT6 as a key tumor suppressor, yet whether point mutations are selected for in cancer remains unclear. In this manuscript, we characterized naturally occurring patient-derived SIRT6 mutations. Strikingly,(More)
Aberrant activation of fundamental cellular processes, such as proliferation, migration and survival, underlies the development of numerous human pathophysiologies, including cancer. One of the most frequently hyperactivated pathways in cancer is the phosphoinositide 3-kinase (PI3K)/Akt signalling cascade. Three isoforms of the serine/threonine protein(More)
