中文摘要 | effects of la3+ and gd3+ on ca2+ influx were investigated in rat hepatoma h-35 cells by measuring the initial rate of ca-45(2+) uptake. it was found that the maximum initial rate of ca2+ uptake was increased six- to ten-fold at low concentrations of la3+ and gd3+. kinetic analyses by measuring the initial rate of ca2+ influx at different external ca2+ concentrations indicated the existence of two intracellular exchangeable components in the basal ca2+ system, with low and high affinities for ca2+, and only one class of ca2+ binding sites was observed in the la3+- or gd3+-treated cells. for high affinity, la3+ and gc(3+) increased both kinetic parameters k-m and v-max of basal ca2+ influx. la3+ and gd3+ compete directly with ca2+ for ca2+ binding site for low affinity. the kinetics is competitive. |
