متن کاملIon channnels and transporters in cancer. 5. Ion channels in control of cancer and cell apoptosis.
Ion channels contribute to virtually all basic cellular processes, including such crucial ones for maintaining tissue homeostasis as proliferation, differentiation, and apoptosis. The involvement of ion channels in regulation of programmed cell death, or apoptosis, has been known for at least three decades based on observation that classical blockers of ion channels can influence cell death rat...
متن کاملIon channels and transporters on the move.
Cell migration plays a crucial role in a variety of (patho)physiological processes such as immune defense, wound healing, and formation of tumor metastases. Detailed models have been developed to describe cytoskeletal mechanisms of migration. However, evidence is accumulating that the activity of ion channels and transporters is also required for optimal cell locomotion.
متن کاملIon selectivity in channels and transporters
A multitude of biological processes requires the participation of specific cations, such as H + , Na + , K + , Ca 2+ , and Mg 2+. Many of these processes can take place only when proteins have the ability to discriminate between different ions with a very high fidelity. How this is possible is a fundamental question that has fascinated scientists for a long time. At the most fundamental level, ...
متن کاملThe Cardiac Ion Channels
Action potentials are mediated by transient changes in ion conductance across the cell surface membrane. These changes in conductance are primarily mediated by ion channels. Ion channels are membrane-embedded proteins that selectively pass specific ions upon opening. Some ion channels are constitutively open; however, most channels open following stimulation, such as through voltage changes, in...
