Starksen et al., J Biol Chem 1987
:
Previous work in our laboratory has demonstrated that PDGF B chain mRNA expression is stimulated in microvascular endothelial cells by phorbol esters ( PMA ), thrombin, and transforming growth factor-beta ( TGF-beta ) and blocked by agents that elevate cyclic AMP ( cAMP )
Zhang et al., J Dermatol 1995
(Carcinoma, Squamous Cell) :
Prostaglandin E1 slightly inhibited PDGF-AB production, transforming growth factor beta 1 promoted PDGF-AB production and interferon-gamma, interleukin-1 alpha, and tumor necrosis factor-alpha failed to exert any influence at all
