Abstract Characteristics of changes in the membrane potential induced by increased Ca2+ inward current in patients with lung cancer are presented. Both the amplitude and the rate of hyperpolarization induced by opening of Ca2+-activated potassium channels are markedly decreased in erythrocytes from patients in comparison with healthy donors. Under conditions of moderate Ca2+ inward current, hyperpolarization is followed by restoration of the membrane potential. This process is more rapid in cancer patients. It is shown that the parameters of hyperpolarization, in their dynamics during antitumor therapy depend on the type of lung cancer.
