FADD, Caspase-3, and Caspase-8 and Incidence of Coronary Events.
OBJECTIVE To investigate the relationship between 3 markers of apoptosis, that is, FADD (Fas-associated death domain-containing protein), caspase-3, and caspase-8, and incidence of coronary events (CEs) in a population-based cohort study. APPROACH AND RESULTS In vitro experiments were performed to assess the response of the apoptotic biomarkers after Fas stimulation of peripheral blood mononu...
متن کاملUnderstanding the Role of the Death Receptor 5/FADD/caspase-8 Death Signaling in Cancer Metastasis.
The normal function of the extrinsic apoptotic pathway is to mediate apoptosis. Thus, this pathway is generally recognized to be critical in host immune surveillance against cancer. However, many studies have suggested that some key components in this pathway including Fas, death receptor 5 (DR5), Fas-associated death domain (FADD) and caspase-8 may contribute to cancer growth or metastasis. Ou...
متن کاملFADD and caspase-8 control the outcome of autophagic signaling in proliferating T cells.
Fas-associated death domain protein (FADD) and caspase-8 (casp8) are vital intermediaries in apoptotic signaling induced by tumor necrosis factor family ligands. Paradoxically, lymphocytes lacking FADD or casp8 fail to undergo normal clonal expansion following antigen receptor cross-linking and succumb to caspase-independent cell death upon activation. Here we show that T cells lacking FADD or ...
متن کاملFADD and caspase-8 mediate priming and activation of the canonical and noncanonical Nlrp3 inflammasomes.
The Nlrp3 inflammasome is critical for host immunity, but the mechanisms controlling its activation are enigmatic. In this study, we show that loss of FADD or caspase-8 in a RIP3-deficient background, but not RIP3 deficiency alone, hampered transcriptional priming and posttranslational activation of the canonical and noncanonical Nlrp3 inflammasome. Deletion of caspase-8 in the presence or abse...
متن کاملFADD regulates NF-κB activation and promotes ubiquitination of cFLIPL to induce apoptosis
Tumor Necrosis Factor-α canonically induces the activation of NF-κB and associated gene product cellular FLICE-like inhibitory protein (cFLIPL) to promote cell survival. Previously, we demonstrated that ectopic expression of the Fas associated death domain (FADD) diminishes the expression of cFLIPL and transduces caspases-8 mediated apoptosis, independent of FasL stimulation in HEK 293T cells. ...
