we have demonstrated previously that cultured rat ovarian granulosa cells synthesize and secrete apoe , and this production of apoe is increased by agents that stimulate protein kinase a ( cyclic amp-dependent enzyme ) ( for example , cholera toxin ) and protein kinase c ( ca2+/phospholipid-dependent enzyme ) ( for example , 12-o-tetradecanoylphorbol-13-acetate , a phorbol ester ) .
