Prostaglandin F2α decreases the affinity of epidermal growth factor receptors in Swiss mouse 3T3 cells via protein kinase C activation

Prostaglandin F2α (PGF2α) selectively decreases the binding of 125I-labelled epidermal growth factor ([125I]EGF) to intact Swiss 3T3 cells. Scatchard analysis reveals that PGF2α decreases the number of high-affinity EGF binding sites without changing the total number of receptors. Prostaglandins E1...
