Prolactin release from the 8-Br-cAMP induced decidualized cells was not affected by EGF ... However, EGF dose-dependently inhibited prolactin release from the stromal cells that were in the process of decidualization by co-stimulation with 8-Br-cAMP and EGF, though there was no significant change in viable cell numbers of the 8-Br-cAMP stimulated decidualizing cells

We have found that FGF-2 ( 2 x 10 ( -11 ) M ) prevents the EGF induced dose dependent increase in PRL levels in control cells, and reversed the EGF stimulating effects in cells from E2-treated rats ... Both FGF-2 ( 2 x 10 ( -11 ) M ) and EGF ( 6.6 x 10 ( -9 ) M ) significantly increase ( > 30 % and > 120 %, respectively ) the PRL levels in response to TRH ( 10 ( -6 ), 10 ( -5 ) M )

Tadokoro et al., Nihon Naibunpi Gakkai Zasshi 1990 : [ The effect of epidermal growth factor (EGF) with estradiol and progesterone on prolactin secretion from cultured human decidual tissues of early pregnancy ] ... We investigated the effect of epidermal growth factor (EGF) with estradiol and progesterone on prolactin secretion by the decidual tissues from the early pregnant endometrium ... The effect of high concentration EGF ( 50 ng/ml ) on the prolactin secretion appeared similar to the isolated decidual tissues
Reaves et al., Mol Endocrinol 1990 (Pituitary Neoplasms) : Treatment with the combined hormones stimulates PRL synthesis approximately 6-fold, but this effect is not sufficient to increase PRL storage, because epidermal growth factor alone increases PRL synthesis to the same extent without affecting storage
Jackson et al., Mol Cell Endocrinol 1990 : Furthermore, the acute stimulatory effects of EGF and TPA on expression of ( -187 ) PRL-CAT were additive
Ramsdell et al., J Cell Physiol 1989 : Thyrotropin releasing hormone (TRH) and epidermal growth factor both enhance prolactin synthesis and substrate adhesion ( a morphological change called stretching ) of GH4 rat pituitary cells
Prysor-Jones et al., J Endocrinol 1987 (Pituitary Neoplasms) : Prolactin secretion by a human pituitary tumour cell line produced in our laboratory was stimulated by TRH, vasoactive intestinal peptide (VIP) and epithelial growth factor (EGF)
Ramsdell et al., Endocrinology 1985 : Thyrotropin releasing hormone and epidermal growth factor stimulate prolactin synthesis by a pathway ( s ) that differs from that used by phorbol esters : dissociation of actions by calcium dependency and additivity ... TRH stimulated PRL production was constant between 10 and 660 microM [ Ca2+ ] e, whereas EGF stimulated PRL production to a similar extent as TRH at 10 microM [Ca2+ ] e, but continued to enhance production with increasing [Ca2+ ] e. TRH elevated [Ca2+ ] i acutely, and at [Ca2+ ] e greater than 100 microM caused both a burst and a plateau phase in elevated [Ca2+ ] i ... We conclude that TPA stimulates PRL production by a highly calcium dependent pathway and that TRH and EGF stimulate PRL production by a different pathway ( s ) requiring lower [ Ca2+ ] i
