title: The effects of gonadotropins on metabolism of isolated rat granulosa cells.
abstract: FSH in vitro, but not LH, increased the O2 uptake of isolated granulosa cells from 23 day old rats previously treated with DES or with DES and FSH. Dose response studies showed that the cells were most sensitive to FSH when the cellular binding of FSH was highest. LH increased the O2 uptake of granulosa cells of untreated 30 day old rats. DES treatment inhibited the LH induced rise in O2 uptake when the rats were implanted with DES capsules unless FSH was injected to induce LH receptors. Addition of dbcAMP in vitro increased O2 uptake of granulosa cells from 30 day old rats at concentrations 10X lower than those required to stimulate O2 uptake in cells from 23 day old rats treated with DES alone.
