Tumor necrosis factor (TNF) family ligand TNF-alpha and Fas ligand (FasL) can trigger apoptosis in solid tumors, but their clinical usage has been limited by hepatotoxicity. TNF-related apoptosis-inducing ligand (TRAIL) is a newly identified member of the TNF family, and its clinical application currently is under a similar debate. Here, we report a recombinant soluble form of human TRAIL (114 ...

Abstract. Flow-mediated vasodilation (FMD) has been demonstrated to be a useful, non-invasive tool for the detection of endothelial dysfunction in atherosclerotic cardiovascular disease, leading cause mortality end-stage kidney disease. The Fas/Fas ligand system apoptosis resulting from activation caspase cascade- contributes pathophysiology atherosclerosis. This ‘apoptotic’ plays central role ...

Fas (APO-1/CD95) is a cell surface receptor that mediates apoptosis when it reacts with Fas ligand (FasL) or Fas antibody. In this study, we analyzed Fas and FasL expression in normal esophageal mucosa and esophageal squamous cell carcinomas. Reverse transcriptase-PCR revealed that Fas, soluble Fas, and FasL were expressed in all eight esophageal squamous carcinoma cell lines analyzed. Furtherm...

Fas-Fas ligand interactions play a central role in the regulation of the immune response. Fas ligand expression by tumors has been implicated in the abrogation of the host antitumor response by killing of Fas-positive effector lymphocytes. We have studied the presence and functional status of Fas and Fas ligand in Ewing's sarcoma. All Ewing's sarcoma cell lines tested expressed Fas on their sur...

Tumors evolve mechanisms to escape immune control by a process called immune editing, which provides a selective pressure in the tumor microenvironment that could lead to malignant progression. A variety of tumor-derived factors contribute to the emergence of complex local and regional immunosuppressive networks, including vascular endothelial growth factor, interleukin-10, transforming growth ...

Many cancers are resistant to Fas-mediated apoptosis despite the expression of Fas. To investigate the mechanisms by which Fas signals are attenuated, we focused on decoy receptor 3 (DcR3). DcR3 is a soluble receptor against Fas ligand belonging to the tumor necrosis factor receptor superfamily and overexpresses in some forms of cancers. Exogenous DcR3 inhibits Fas-mediated apoptosis in Fas-sen...
