A Fas-associated protein factor, FAF1, potentiates Fas-mediated apoptosis.
Fas, a member of the tumor necrosis factor receptor family, can induce apoptosis when activated by Fas ligand binding or anti-Fas antibody crosslinking. Genetic studies have shown that a defect in Fas-mediated apoptosis resulted in abnormal development and function of the immune system in mice. A point mutation in the cytoplasmic domain of Fas (a single base change from T to A at base 786), rep...
متن کاملInhibition of Fas (CD95) expression and Fas-mediated apoptosis by oncogenic Ras.
The ras oncogene plays an important role in the multistep progression to cancer by activation of signal transduction pathways that contribute to aberrant growth regulation. Although many of these effects are cell autonomous, the ras oncogene also regulates the expression of genes that alter host/tumor interactions. We now extend the mechanisms through which ras promotes tumor survival by demons...
متن کاملOncogenic Ras inhibits Fas ligand-mediated apoptosis by downregulating the expression of Fas.
Tumor growth is the result of deregulated tissue homeostasis which is maintained through the delicate balance of cell growth and apoptosis. One of the most efficient inducers of apoptosis is the death receptor Fas. We report here that oncogenic Ras (H-Ras) downregulates Fas expression and renders cells of fibroblastic and epitheloid origin resistant to Fas ligand-induced apoptosis. In Ras-trans...
متن کاملSemaphorin3A signaling controls Fas (CD95)-mediated apoptosis by promoting Fas translocation into lipid rafts.
Semaphorins and their receptors (plexins) have pleiotropic biologic functions, including regulation of immune responses. However, the role of these molecules inside the immune system and the signal transduction mechanism(s) they use are largely unknown. Here, we show that Semaphorin3A (Sema3A) triggers a proapoptotic program that sensitizes leukemic T cells to Fas (CD95)-mediated apoptosis. We ...
متن کاملCD47 augments Fas/CD95-mediated apoptosis.
Fas (CD95) mediates apoptosis of many cell types, but the susceptibility of cells to killing by Fas ligand and anti-Fas antibodies is highly variable. Jurkat T cells lacking CD47 (integrin-associated protein) are relatively resistant to Fas-mediated death but are efficiently killed by Fas ligand or anti-Fas IgM (CH11) upon expression of CD47. Lack of CD47 impairs events downstream of Fas activa...
