Title: Calmodulin and Ca2+ in normal and transformed cells. Author: Veigl ML, Sedwick WD, Vanaman TC. Journal: Fed Proc; 1982 May; 41(7):2283-8. PubMed ID: 6281082. Abstract: Numerous lines of evidence implicate calcium and calmodulin (CaM) as regulators of cell growth and functional differentiation. In light of this evidence, several studies of the possible involvement of the CaM system in cellular transformation by RNA and DNA tumor viruses have been carried out. This paper summarizes the evidence linking calcium and CaM to the regulation of cell growth and critically examines the evidence that increases in CaM levels occur in transformed versus normal cells. A nontraumatic method for synchronizing both normal and transformed chick fibroblasts is presented. This method is utilized in a comparison of CaM level throughout the cell cycle of Rous sarcoma virus transformed and normal chick embryo fibroblasts. These studies best support the hypothesis that the observed differences in CaM levels between transformed and normal cultures under optimal growth conditions may largely reflect differences in the proportion of cells in a dividing versus a nondividing state.[Abstract] [Full Text] [Related] [New Search]
