Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of the tumor necrosis factor (TNF) family, binds to several cell-surface receptors with distinct functions (agonistic receptors 1 and 2 [TRAIL-R1, TRAIL-R2]; decoy receptors 3 and 4 [TRAIL-R3, TRAIL-R4]). Expression and function was characterized in patients with myelodysplastic syndromes (MDSs). While normal marrow showe...

Tumor necrosis factor-related apoptosis-inducing-ligand (TRAIL/Apo-2 ligand) induces apoptosis in the majority of cancer cells without appreciable effect in normal cells. Here, we report the effects of TRAIL on apoptosis in several human breast cancer cell lines, primary memory epithelial cells, and immortalized nontransformed cell lines, and we examine whether chemotherapeutic agents augment T...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to induce apoptosis in a variety of tumorigenic and transformed cell lines but not in many normal cells. Hence, TRAIL has the potential to be an ideal cancer therapeutic agent with minimal cytotoxicity. FLICE inhibitory protein (c-FLIP) is an important regulator of TRAIL-induced apoptosis. Here, we show that persiste...

To build commercial robots, skid-steering mechanical design is of increased popularity due to its manufacturing simplicity and unique mechanism. However, these also cause significant challenges on software algorithm design, especially for the pose estimation (i.e., determining robot’s rotation position) since they change their orientation with an inevitable skid. tackle this problem, we propose...

Research on TNF-related apoptosis-inducing ligand (TRAIL) and TRAIL receptors has advanced tremendously over the past 17 years. Initial observations of TRAIL and TRAIL receptor-mediated tumor cell toxicity led to enthusiasm of exploiting this selective, malignant cell killing for cancer therapy. Further examination revealed aberrant TRAIL signaling in some cancer cells leading to protection fro...

The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL or Apo2L) is a potent inducer of death of cancer but not normal cells, which suggests its potential use as a tumor-specific antineoplastic agent. TRAIL binds to the proapoptotic death receptors DR4 and the p53-regulated proapoptotic KILLER/DR5 as well as to the decoy receptors TRID and TRUNDD. In the present studies, we identifi...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising anticancer agent with tumor-selective apoptotic activity. TRAIL plays a role in the innate and adaptive immune response and autoimmune disease and may also be involved in hepatic cell death and inflammation. For these reasons, chronic exposure to TRAIL may have deleterious side effects in patients as a cancer therape...

BACKGROUND The fact that the receptors for the TNF-related apoptosis inducing ligand (TRAIL) are almost invariably expressed in colorectal cancer (CRC) represents the rationale for the employment of TRAIL-receptors targeting compounds for the therapy of patients affected by this tumor. Yet, first reports on the use of these bioactive agents provided disappointing results. We therefore hypothesi...

We present ground-based optical and Spitzer Space Telescope infrared (IR) imaging observations of the ecliptic (Jupiter-family) comet 21P/Giacobini-Zinner, the parent body of the Draconid meteor stream, during its 2005 apparition. The onset of nucleus activity occurred at a pre-perihelion heliocentric distance, rh 3.80 AU, while post-perihelion 21P was dusty (peak Afρ = 131 cm−1) and active out...
