Anisomycin and cycloheximide, like growth factors, stimulate rapidly ATP turnover in 3T3 cells.

Addition of EGF and insulin to quiescent cultures of 3T3 cells induce a rapid stimulation of ATP turnover. We show that, like growth factors, anisomycin and cycloheximide, two inhibitors of protein synthesis, induce in 3T3 cells, a rapid increase in ATP turnover. However, this effect was not the result of the inhibition of protein synthesis since puromycin, in the same experimental conditions, did not stimulate ATP turnover.
