Fas is a cell surface protein that can mediate apoptosis and belongs to the tumor necrosis factor (TNF) receptor family. Anti-Fas antibody induces apoptotic cell death in sensitive cells. Because many chemotherapeutic drugs are capable of initiating pathways leading to apoptosis, we determined the effect of cyclophosphamide, one of the most widely used anticancer drugs, on Fas mediated apoptosi...
Purpose: To investigate the protective role of evodiamine, a naturally occurring anti-inflammatory, antioxidant, and anti-apoptotic compound, against cadmium-induced cytotoxicity in proximal tubular cells (human kidney 2; HK-2).
 Methods: HK-2 were treated with different concentrations evodiamine (5, 20, 50 ?M) for 2 h then incubated 40 ?M cadmium chloride another 24 h. Cell viability apop...
We have previously shown that the proliferative response of T cells to antigenic or mitogenic stimulus decreased with age and that caloric resection (CR) attenuated the age-related decline in proliferation and IL-2 expression. Because activation-induced apoptosis is known to regulate cell proliferation and eliminate the high number of activated cells during an immune response, it was of interes...
BACKGROUND We have previously reported that anti-death receptor 5 (DR5) monoclonal antibody (mAb) is therapeutically effective in the treatment of rheumatoid arthritis (RA) in a collagen-induced arthritis rat model. However, the molecular mechanism and the effect of anti-DR5 mAb on proapoptotic genes and cytokine secretion in the human fibroblast-like synovial cells (FLS) requires further clari...
Fas belongs to the family of type-1 membrane proteins that transduce apoptotic signals. In the present studies, we characterized signaling during Fas-induced apoptosis in RPMI-8226 and IM-9 multiple myeloma (MM) derived cell lines as well as patient plasma cell leukemia cells. Treatment with anti-Fas (7C11) monoclonal antibody (MoAb) induced apoptosis, evidenced by internucleosomal DNA fragment...
The herpes simplex virus type 1 (HSV-1) latency associated transcript (LAT) gene has anti-apoptosis activity that directly or indirectly enhances the virus's reactivation phenotype in small animal models. The first 1.5 kb of the primary 8.3 kb LAT is sufficient and some or all of it is necessary for LAT's anti-apoptosis in transient transfection assays and for LAT's ability to enhance the react...
Loss of epithelial barrier integrity is considered an early step in the pathogenesis of Crohn's disease (CD), and the rate of enterocyte apoptosis is one of the determinants of the intestinal barrier function. Tumor necrosis factor-alpha (TNF-alpha), one of the major proinflammatory mediators in CD, is one of the extrinsic signals which initiate apoptosis of enterocytes. The aim of this study w...
TRAIL can induce apoptosis in some cancer cells and is an immune effector in the surveillance and elimination of developing tumors. Yes, some cancers are resistant to TRAIL. Delphinidin, a polyphenolic compound contained in brightly colored fruits and vegetables, has anti-inflammatory, anti-oxidant, and anti-tumorigenic activities. Here we showed that delphinidin sensitized TRAIL-resistant huma...
Plant sterols have shown potent anti-proliferative effects and apoptosis induction against breast and prostate cancers. However, the effect of sterols against hepatic cancer has not been investigated. In the present study, we assessed whether the stigmasterol isolated from Navicula incerta possesses apoptosis inductive effect in hepatocarcimona (HepG2) cells. According to the results, Stigmaste...
Black seed (Nigella sativa) is considered as a biological response modifier. Thymoquinone (TQ) is the bioactive and the most abundant constituent of the volatile oil of this seed which has been shown to possess anti-inflammatory, antioxidant and anti-neoplastic effects. In this study, the effect of TQ on HepG2 cell line was investigated in an attempt to identify its potential mechanism of actio...
