Death receptor signals to the mitochondria [PDF]
Apoptosis is the best-characterized form of programmed cell death (PCD) and is of fundamental importance in tissue homeostasis. In mammalian systems, there are two major pathways that are involved in the initiation of apoptosis: the "extrinsic" death receptor pathway and the "intrinsic" mitochondrial pathway.

Volatile oil of Teucrium alopecurus sensitizes colon cancer cells to TRAIL-induced cell death
TNF-related apoptosis-inducing ligand (TRAIL/Apo2L), a member of cytokine family, is known to selectively induce apoptosis in cancer cells. However, developing resistance to TRAIL is a major obstacle in cancer therapy.

Colorectal cancer (CRC) remains a leading cause of cancer death, and its mortality is associated with metastasis and chemoresistance. We demonstrate that oxaliplatin-resistant CRC cells are sensitized to TRAIL-mediated apoptosis.

TRAF2 Controls Death Receptor-Induced Caspase-8 Processing and Facilitates Proinflammatory Signaling
Tumor necrosis factor (TNF) receptor associated factor-2 (TRAF2) knockout (KO) cells were generated to investigate the role of TRAF2 in signaling by TNFR1 and the CD95-type death receptors (DRs) TRAILR1/2 and CD95.

Microsatellite instability, KRAS mutations and cellular distribution of TRAIL-receptors in early stage colorectal cancer. [PDF]
Thus, we evaluated the immunofluorescence pattern of TRAIL-receptors and E-cadherin to assess the fraction of membrane-bound TRAIL-receptors in 231 selected patients with early-stage CRC undergoing surgical treatment only.

Life and death by death receptors
ABSTRACT Death receptors are members of the tumor necrosis factor receptor superfamily characterized by a cytoplasmic region known as the “death domain” that enables the receptors to initiate cytotoxic signals when engaged by cognate ligands. Binding to the ligand results in receptor aggregation and recruitment of

Emerging key roles for P2X receptors in the kidney [PDF]
P2X ionotropic non-selective cation channels are expressed throughout the kidney and are activated in a paracrine or autocrine manner following the binding of extracellular ATP and related extracellular nucleotides.

GABAB receptors control neuronal excitability via slow and prolonged inhibition in the central nervous system. One important function of GABAB receptors under physiological condition is to prevent neurons from shifting into an overexcitation state which ...

A Mechanism for Death Receptor Discrimination by Death Adaptors [PDF]
The death domain and death effector domain are two common motifs that mediate protein-protein interactions between components of cell death signaling complexes. The mechanism by which these domains engage their binding partners has been explored by extensive mutagenesis of two death adaptors, FADD and TRADD, suggesting that a death adaptor can ...
