Cutting edge: TRAIL deficiency accelerates hematological malignancies.

چکیده
TNF apoptosis-inducing ligand is attracting considerable interest as a potential extrinsic tumor suppressor mechanism, although previous reports have conveyed somewhat contrasting views regarding the likely importance of this pathway. In this study, we provide the first evaluation of spontaneous tumor formation over the life span of TRAIL-deficient mice. Interestingly, >25% of these mice do develop lymphoid malignancies after 500 days of life. TRAIL suppressed the initiation and development of both tumors of lymphoid and stromal origin in the context of the loss of at least one p53 allele. Specific examination of the role of TRAIL in Her2/neu oncogene-driven mammary epithelial cancer revealed no critical role for TRAIL despite the inherent TRAIL sensitivity of such mammary carcinomas. Overall, the data indicate an important function of TRAIL in controlling carcinogenesis, but suggest that further examination of this pathway in epithelial malignancies is warranted.

Critical roles of tumor necrosis factor-related apoptosis-inducing ligand in type 1 diabetes.
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis of tumor cells but not most normal cells. Its roles in normal nontransformed tissues are not clear. To explore the potential roles of TRAIL in type 1 diabetes, we examined the consequences of TRAIL blockade or TRAIL deficiency in two animal models of autoimmune diabetes. In the first model, NOD m...

Hematological malignancies treatment improved over the last years resulting in increased achievement of complete or partial remission, but unfortunately high relapse rates are still observed. Therefore, sustainment of long-term remission is crucial. Immune system has a key role in tumor surveillance. Natural killer (NK) cells, at the frontier of innate and adaptive immune system, have a central...
متن کاملDetermination of Serologic and Molecular Prevalence of Hepatitis Type B, C, and G Infections in Patients with Hematological Malignancy in the South of Fars Province, Iran
Background & Objectives: Hepatitis type G virus (HGV) is a flavivirus with RNA genome which has high nucleotide and amino acid similarity with HCV. HGV can infect blood lymphocytes for long period and may have role in inducing or complicating the clinical outcomes in patients with hematological malignancies. Therefore in this study the prevalence of HGV, HCV, and HBV infections were evaluated i...
