Abstract

Incubation of Swiss mouse 3T3 cells at 37°C with bovine brain‐derived growth factor (BDGF) decreased the cell surface 125I‐EGF binding activity of these cells by 70–80%. This down‐modulation of the EOF receptor by BDGF was time, temperature, and dose dependent Scatchard plot analysis indicated that BDGF binding led to a selective decrease in the number of high‐affinity EGF receptors. The BDGF‐induced down‐modulation of the EGF receptor was completely blocked by protamine, a potent inhibitor of receptor binding and mitogenic activities of BDGF.
