Caffeine-mediated inhibition of calcium release channel inositol 1,4,5-trisphosphate receptor subtype 3 blocks glioblastoma invasion and extends survival.
Calcium signaling is important in many signaling processes in cancer cell proliferation and motility including in deadly glioblastomas of the brain that aggressively invade neighboring tissue. We hypothesized that disturbing Ca(2+) signaling pathways might decrease the invasive behavior of giloblastoma, extending survival. Evaluating a panel of small-molecule modulators of Ca(2+) signaling, we ...
متن کاملTransient release of calcium from inositol 1,4,5-trisphosphate-specific stores regulates mouse preimplantation development.
Inositol 1,4,5-trisphosphate can regulate growth and differentiation by modulating the release of intracellular Ca2+ in a variety of cellular systems, and it is involved in oocyte activation. Recent studies suggest that mammalian preimplantation development may also be regulated by the release of Ca2+ from intracellular stores. The rate of cavitation and cell division was accelerated after a tr...
متن کاملRegional differences in calcium-release channels from heart.
The heart is a heterogeneous tissue composed of several cell types tailored for specialized functions. We found that intracellular channels also exhibit regional specialization. In cardiac and skeletal muscle these channels are called the calcium-release channel and are identified by activation with either calcium or caffeine and inhibition by the hexavalent cation ruthenium red. The calcium-re...
متن کاملCa2+ released via IP3 receptors is required for furrow deepening during cytokinesis in zebrafish embryos.
We have previously visualized three Ca2+ transients, generated by release from intracellular stores, which are associated with cytokinesis during the early cell division cycles of zebrafish embryos: the furrow positioning, propagation and deepening transients. Here we demonstrate the requirement of the latter for furrow deepening, and identify the Ca2+ release channels responsible for generatin...
متن کاملIP3 Receptor-Mediated Calcium Signaling and Its Role in Autophagy in Cancer
Calcium ions (Ca2+) play a complex role in orchestrating diverse cellular processes, including cell death and survival. To trigger signaling cascades, intracellular Ca2+ is shuffled between the cytoplasm and the major Ca2+ stores, the endoplasmic reticulum (ER), the mitochondria, and the lysosomes. A key role in the control of Ca2+ signals is attributed to the inositol 1,4,5-trisphosphate (IP3)...
