PF4 prevents p21Cip1/WAF1 downregulation in HUVEC stimulated by EGF. HUVEC lysates collected at the specified times following EGF (20 ng/mL) stimulation with (+) or without (−) 2 μg/mL PF4 were separated by SDS-PAGE and p21Cip1/WAF1 was immunoblotted. Results shown are representative of three independent experiments.
