Ion Channels And The Cancer — Enes Akyüz

It is known that the pathogenesis of human cancer involves the accumulation of multiple molecular anomalies ese molecular changes can be listed as DNA sequence changes point mutations loss of heterozygosity up regulation down regulation of mRNA levels and expressive functional changes in the gene encoded ion channels Ion channels are expressed in almost all living cells and form a pathway for charged ions formed from dissolved salts including calcium Ca2 potassium K sodium Na and chloride Cl ions to pass through the lipid membrane e non functional behavior of ion channels in any of its roles such as regulating cell cycle of proliferating cells interacting with membrane potential inhibiting apoptosis altering intracellular Ca2 balance and adjusting cell contraction is thought to cause cancer In the light of this information the crucial roles of the involvement of ion channels in the cancer mechanism have been revealed in the last decadeand have a central importance in cancer pathophysiology Accordingly the role of ion channels in common types of cancer is presented to readers
