ResumenFetal brown adipocyte primary cultures increase DNA synthesis; cell number; and DNA, RNA, and protein contents in response to 10% fetal calf serum, IGF-I, and EGF plus vasopressin plus bombesin when added for 64 h to quiescent cells. IGF-I is a complete growth factor in this system while EGF needs the presence of vasopressin plus bombesin for its maximal proliferative effects. These mitogens induce the genetic expression of G6P dehydrogenase, increasing its mRNA content as well as its specific activity and amount of immunoreactive protein. The presence of cAMP elevating agents prevents the stimulatory effect of EGF plus vasopressin plus bombesin on DNA synthesis, cell number, and DNA content as well as on the induction of G6P dehydrogenase expression. Thus, changes on the proliferative state of these cells are associated with the level of expression of G6P dehydrogenase.
