“Only MAPK activation induced by PDGF-BB was reduced by pretreatment with DHEA , although DHEA did not affect the MAPK activation induced by EGF or bFGF.”
“The increase of cAMP by PDGF-BB was augmented by pretreatment with DHEA , although DHEA alone did not affect cAMP.”
“These results suggest that DHEA inhibited MAPK activation induced by PDGF-BB via PGE2 overproduction and subsequent cAMP-dependent pathway in human male aortic SMCs.”
