Particular protein kinase inhibitors block a senescence-like phenomenon in SVts8 cells induced by a shift up in temperature. We characterized cellular proteins with affinity chromatography using one such inhibitor as a ligand. Two proteins of 56 and 100 kDa were found to be dephosphorylated specifically, probably due to induction of a protein phosphatase activity(s).
