Tamoxifen Blocks Chloride Channels
Tamoxifen is an antiestrogen frequently used in the treatment of breast cancer and is currently being assessed as a prophylactic for those at high risk of developing tumors. We have found that tamoxifen and its derivatives are highaffinity blockers of specific chloride channels. This blockade appears to be independent of the interaction of tamoxifen with the estrogen receptor and therefore refl...
متن کاملCalcium-activated chloride channels.
Calcium-activated chloride channels (CaCCs) play important roles in cellular physiology, including epithelial secretion of electrolytes and water, sensory transduction, regulation of neuronal and cardiac excitability, and regulation of vascular tone. This review discusses the physiological roles of these channels, their mechanisms of regulation and activation, and the mechanisms of anion select...
متن کاملCLC chloride channels and transporters.
CLC proteins are found in cells from prokaryotes to mammals and perform functions in plasma membranes and intracellular vesicles. Several genetic human diseases and mouse models underscore their broad physiological functions in mammals. These functions range from the control of excitability to transepithelial transport, endocytotic trafficking and acidification of synaptic vesicles. The recent ...
متن کامل-activated Chloride Channels Go Molecular
With the sequencing of the human genome it turned out that many of the genetically identified genes have an unknown function and one of the major problems of biology is the “annotation” of the genome. But the reverse problem persists, i.e., that for many functionally well-defined proteins the coding gene has not been identified. This reverse problem is difficult to tackle because the molecular ...
متن کاملMitochondrial potassium and chloride channels.
Channels selective for potassium or chloride ions are present in inner mitochondrial membranes. They probably play an important role in mitochondrial events such as the formation of delta pH and regulation of mitochondrial volume changes. Mitochondrial potassium and chloride channels could also be the targets for pharmacologically active compounds such as potassium channel openers and antidiabe...
