Expression of ryanodine receptors in human embryonic kidney (HEK293) cells.
It has been shown previously that mobilization of caffeine-sensitive intracellular calcium (Ca2+i) stores increased the release of amyloid beta-peptide (Abeta) from transfected human embryonic kidney cells (HEK293) [Querfurth, Jiang, Geiger and Selkoe (1997) J. Neurochem. 69, 1580-1591]. The present study was to test the hypothesis that the caffeine/Abeta responses were due to interactions with...
متن کاملStructure and function of ryanodine receptors.
Membrane depolarization, neurotransmitters, and hormones evoke a release of Ca2+ from intracellular Ca(2+)-storing organelles like the endoplasmic reticulum and, in muscle, the sarcoplasmic reticulum (SR). In turn, the released Ca2+ serves to trigger a variety of cellular responses. The presence of Ca2+ pumps to replenish intracellular stores was described more than 20 years ago. The presence o...

translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولIncreased Expression of TRAIL and Its Receptors on Peripheral T-Cells in Type 1 Diabetic Patients
Background: Type-I diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. TNF-related apoptosis-inducing ligand (TRAIL) is a type-II membrane protein of the TNF superfamily which is expressed in different tissues, including pancreas and lymphocytes. In humans, TRAIL interacts with four membrane receptors. TRAIL-R1 and TRAIL-R2...
متن کاملRyanodine receptors: structure, expression, molecular details, and function in calcium release.
Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca(2+) from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle. RyRs are the largest known ion channels (> 2MDa) and exist as three mammalian isoforms (RyR 1-3), all of which are homotetrameric proteins that interact with a...
