title: Effect of ciclosporin A on epidermal keratinocytes in vitro: lack of a direct effect on calmodulin.
abstract: Calmodulin, a major calcium-binding protein, is important in the regulation of cell proliferation. In human keratinocytes we found that culture confluence was accompanied by a decrease in calmodulin content. Ciclosporin A, 1-10 micrograms/ml, was found to inhibit the proliferation of the cells but did not affect their calmodulin content as measured by bioassay or radioimmunoassay.
