Because the CaR is a G protein coupled receptor ( GPCR ) , it is likely to transactivate the epidermal growth factor receptor ( EGFR ) or the platelet derived growth factor receptor ( PDGFR ) . ^^^ In this study , we hypothesized that activation of the CaR transactivates the EGFR or PDGFR , and examined whether transactivation affects PTHrP secretion in PC 3 human prostate cancer cells . ^^^ Taken together , these findings indicate that activation of the CaR transactivates the EGFR , but not the PDGFR , leading to phosphorylation of ERK1 / 2 and resultant PTHrP secretion , although CaR EGFR ERK might not be the only signaling pathway for PTHrP secretion . ^^^
