Large meteors (or superbolides [Ceplecha Z, et al. (1999) Meteoroids 1998:37-54]), although rare in recorded history, give sobering testimony to civilization's inherent vulnerability. A not-so-subtle reminder came on the morning of February 15, 2013, when a large meteoroid hurtled into the Earth's atmosphere, forming a superbolide near the city of Chelyabinsnk, Russia, ∼1,500 km east of Moscow,...
BACKGROUND TRAIL/Apo2L is a pro-apoptotic ligand of the TNF family that engages the apoptotic machinery through two pro-apoptotic receptors, TRAIL-R1 and TRAIL-R2. This cell death program is tightly controlled by two antagonistic receptors, TRAIL-R3 and TRAIL-R4, both devoid of a functional death domain, an intracellular region of the receptor, required for the recruitment and the activation of...
The lack of effective therapy for disseminated renal cell carcinoma (RCC) has stimulated the search for novel treatments including immunotherapeutic strategies. However, poor therapeutic responses and marked toxicity associated with immunological agents has limited their use. The tumor necrosis factor family member tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)/Apo-2 ligand ind...
Let T be a trail of a graph G. T is a spanning trail (S-trail) if T contains all vertices of G. Tis a dominating trail (D-trail) if every edge of G is incident with a t least one vertex of T. A circuit is a nontrivial closed trail. Sufficient conditions involving lower bounds on the degree-sum of vertices or edges are derived for graphs to have an S-trail, S-circuit, D-trail, or D-circuit. Ther...
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) demonstrates specific anti-cancer activity, but insufficient efficacy in patients. A fusion protein Fn14·TRAIL, that combines soluble TRAIL molecule with a specific TWEAK receptor Fn14, is a better apoptosis-inducer for hepatocellular carcinomas than soluble TRAIL. However, Fn14·TRAIL does not effectively induce apoptosis in tumors...
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in cancer cells but not in normal cells. However, studies have indicated that more than half of human tumors exhibit TRAIL resistance. Although the mechanism of TRAIL resistance is not understood, it represents a barrier to any TRAIL-mediated gene therapy approach. In addition, no correlation bet...
TRAIL induces selective tumor cell death through TRAIL-R1 and TRAIL-R2. Despite the fact that these receptors share high structural homologies, induction of apoptosis upon ER stress, cell autonomous motility and invasion have solely been described to occur through TRAIL-R2. Using the TALEN gene-editing approach, we show that TRAIL-R1 can also induce apoptosis during unresolved unfolded protein ...
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors are promising targets for the selective eradication of tumor cells while sparing normal cells. Currently, both recombinant TRAIL proteins and TRAIL receptor agonistic antibodies are being tested in the clinic, showing encouraging antitumor activities and mild side effects. Unfortunately, resistance to TRAIL therapy is fre...
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been reported to exhibit therapeutic activity in cancer. However, many tumors remain resistant to treatment with TRAIL. Therefore, small molecules that potentiate the cytotoxic effects of TRAIL could be used for combinatorial therapy. Here we found that the ionophore antibiotic salinomycin acts in synergism with TRAIL, enhancin...
