Multiple myeloma (MM) remains incurable and novel treatments are urgently needed. Preclinical in vitro and in vivo evaluations were performed to assess the potential therapeutic applications of human recombinant tumor necrosis factor (TNF)-related apoptosis-inducing ligand/Apo2 ligand (TRAIL/Apo2L) in MM. TRAIL/Apo2L potently induced apoptosis of MM cells from patients and the majority of MM ce...

INTRODUCTION Agonistic antibodies targeting TRAIL-receptors 1 and 2 (TRAIL-R1 and TRAIL-R2) are being developed as a novel therapeutic approach in cancer therapy including pancreatic cancer. However, the cellular distribution of these receptors in primary pancreatic cancer samples has not been sufficiently investigated and no study has yet addressed the issue of their prognostic significance in...

Smac mimetics are being developed as a new class of anticancer therapies. Because the single-agent activity of Smac mimetics is very limited, rational combinations represent a viable strategy for their clinical development. The combination of Smac mimetics with TNF-related apoptosis inducing ligand (TRAIL) may be particularly attractive because of the low toxicity of TRAIL to normal cells and t...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can induce apoptosis in a wide variety of transformed human cells in vitro. In this study, the antitumor activity of recombinant TRAIL was analyzed in mice bearing human colon carcinoma tumors. We found that these tumors displayed a differential sensitivity to TRAIL in vivo that paralleled their susceptibility to TRAIL-induced apop...

Mesenchymal stem cells (MSC) are emerging as novel cell-based delivery agents; however, a thorough investigation addressing their therapeutic potential in medulloblastomas (MB) has not been explored to date. In this study, we engineered human MSC to express a potent and secretable variant of a tumor specific agent, tumor necrosis factor-apoptosis-inducing ligand (S-TRAIL) and assessed the abili...

The immune system eliminates Chlamydia trachomatis infection through inflammation. However, uncontrolled inflammation can enhance pathology. In mice, TNF-related apoptosis-inducing ligand receptor (TRAIL-R), known for its effects on apoptosis, also regulates inflammation. In humans, the four homologues of TRAIL-R had never been investigated for effects on inflammation. Here, we examined whether...

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily and has selective antitumor activity. Although TNF-alpha-induced intracellular signaling pathways have been well studied, TRAIL signaling is not fully understood. Here, we identified a novel TRAIL receptor-binding protein, protein arginine methyltransferase 5 (PRMT5), as a result of proteomi...

PURPOSE To study the association between weather-related measures and objectively measured trail use across 3 seasons. BACKGROUND Weather has been reported as a barrier to outdoor physical activity (PA), but previous studies have explained only a small amount of the variance in PA using weather-related measures. METHODS The dependent variable of this study was trail use measured as mean hou...

Although tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its agonistic receptors have been identified as highly promising antitumor agents preferentially eliminating cancer cells with minimal damage, the emergence of TRAIL resistance in most cancers may contribute to therapeutic failure. Thus, there is an urgent need for new approaches to overcome TRAIL resistance. Gold nano...

TRAIL is a recently described member of the TNF superfamily. The ability of TRAIL to induce apoptosis in a large number of tumors has stimulated interest in TRAIL as a tumor therapeutic agent. Although TRAIL mRNA is expressed in a number of tissues, its functional significance to various organs is unknown. Because tumors rarely develop in the eye, we have examined this organ for functional TRAI...
