Progesterone 150-162 oxytocin/neurophysin I prepropeptide Homo sapiens 183-191 18081527-10 2007 In contrast, all 6 oxytocin-treated mares maintained progesterone concentrations > 1.0 ng/mL continuously through day 30.

Progesterone 21-33 oxytocin/neurophysin I prepropeptide Homo sapiens 43-51 16254031-1 2006 Experiments were conducted to characterize the nongenomic effects of progesterone (P4) on binding of oxytocin (OT) to its receptor and signal transduction in the ovine endometrium. Progesterone 69-81 oxytocin/neurophysin I prepropeptide Homo sapiens 101-109 15811355-1 2005 Estrogen administration results in increased release of the oxytocin (OT) prohormone reflected by increases in oxytocin intermediate peptide (OT Int) in both animal models and humans, and sequential treatment of ovariectomized rats with estrogen/progesterone then progesterone withdrawal leads to increased hypothalamic OT mRNA. Progesterone 246-258 oxytocin/neurophysin I prepropeptide Homo sapiens 60-68 23201337-5 2013 Women diagnosed with BPD had significantly reduced oxytocin concentrations, even after controlling for estrogen, progesterone, and contraceptive intake. Progesterone 113-125 oxytocin/neurophysin I prepropeptide Homo sapiens 51-59 18655896-8 2008 Here we discuss the mechanisms involved, which include induction of central inhibitory opioid tone by the progesterone neurosteroid metabolite, allopregnanolone, and act to prevent activation of oxytocin neurons by inappropriate stimuli at the end of pregnancy. Progesterone 106-118 oxytocin/neurophysin I prepropeptide Homo sapiens 195-203 2173139-0 1990 Behavioral effects of progesterone associated with rapid modulation of oxytocin receptors. Progesterone 22-34 oxytocin/neurophysin I prepropeptide Homo sapiens 71-79 11357060-9 2001 The present results suggested that IGFBP-4, as well as GH, IGF-I, estradiol, LH and oxytocin, is a potent regulator of porcine ovarian steroid (progesterone), nonapeptide hormone (oxytocin), growth factor (IGF-I) and growth factor-binding protein (IGFBP-3) release. Progesterone 144-156 oxytocin/neurophysin I prepropeptide Homo sapiens 84-92 20681138-6 2000 During the period of oxytocin and PGFM pulses, progesterone concentrations decreased (P < 0.001) from mid-dioestrous to oestrous values. Progesterone 47-59 oxytocin/neurophysin I prepropeptide Homo sapiens 21-29 9640267-1 1998 The present study was undertaken to determine whether the administration of progesterone, early in the oestrous cycle, had an influence on ovarian oxytocin secretion and on peripheral concentrations of the prostaglandin F2 alpha metabolite 13,14-dihydro-15-keto PGF2 alpha (PGFM) in the ovarian auto-transplanted ewe. Progesterone 76-88 oxytocin/neurophysin I prepropeptide Homo sapiens 147-155 8589505-2 1995 Although it has been suggested that estradiol (E) and progesterone (P) are involved in the expression of oxytocin receptors (OTRs), no consensus opinion has been formed on this topic. Progesterone 54-66 oxytocin/neurophysin I prepropeptide Homo sapiens 105-113 7600764-2 1995 Bovine granulosa cells secrete oxytocin, and oxytocin modulates the production of progesterone by granulosa cells in vitro. Progesterone 82-94 oxytocin/neurophysin I prepropeptide Homo sapiens 45-53 8714007-2 1995 Several in vitro models have been utilized to examine the most obvious role for OT in luteal function, that of its effect on progesterone (P) production. Progesterone 125-137 oxytocin/neurophysin I prepropeptide Homo sapiens 80-82 8425493-1 1993 In the porcine corpora lutea (CL), prostaglandin F2 alpha (PGF2 alpha) and oxytocin (OXT) inhibit progesterone (P) but stimulate estradiol (E2) secretion from luteal cells kept under primary culture conditions.

Progesterone 138-150 oxytocin/neurophysin I prepropeptide Homo sapiens 115-123 1730809-2 1992 In cultures of dispersed luteal cells obtained from several animal species prostaglandin F2 alpha (PGF2 alpha) and oxytocin (OXT) inhibit progesterone (P) secretion, indicating a luteolytic effect of these substances. Progesterone 138-150 oxytocin/neurophysin I prepropeptide Homo sapiens 125-128 14613532-7 2003 Evidence is also presented for potential autocrine/paracrine actions of oxytocin in regulating progesterone production by luteal and granulosa cells. Progesterone 95-107 oxytocin/neurophysin I prepropeptide Homo sapiens 72-80 11739013-7 2001 Binding of OT by antiserum suppressed IGFBP-3, PGE, but not progesterone secretion. Progesterone 60-72 oxytocin/neurophysin I prepropeptide Homo sapiens 11-13 11357060-5 2001 It was observed that GH, IGF-I, estradiol, LH and oxytocin alter the progesterone, oxytocin, IGF-I and IGFBP-3 release by porcine ovarian granulosa cells.

Progesterone 57-69 oxytocin/neurophysin I prepropeptide Homo sapiens 10-18 8077313-2 1993 In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein cells causes intracellular calcium (Ca2+) signals and affects progesterone release. Progesterone 209-221 oxytocin/neurophysin I prepropeptide Homo sapiens 94-102 8077313-14 1993 Moreover, oxytocin release induced by hCG and a stimulatory effect of oxytocin on the hCG-induced progesterone production during the period of maximal responsiveness of cultured cells were found. Progesterone 98-110 oxytocin/neurophysin I prepropeptide Homo sapiens 70-78 8077313-15 1993 We, therefore, propose that oxytocin may have autocrine and/or paracrine functions in human granulosa-lutein cells, including fine-tuning of progesterone release. Progesterone 141-153 oxytocin/neurophysin I prepropeptide Homo sapiens 28-36 1786704-15 1991 In summary, constant infusion of oxytocin extended luteal lifespan, prolonged secretion of progesterone, and inhibited oxytocin-induced secretion of PGF2 alpha.

Progesterone 75-87 oxytocin/neurophysin I prepropeptide Homo sapiens 67-70 3364500-7 1988 In the early luteal phase oxytocin (4 to 800 mU; 1 mU is equivalent to 2 ng) inhibited basal and human chorionic gonadotropin-stimulated progesterone production by dispersed luteal cells, but in the late luteal phase 200 to 800 mU oxytocin inhibited only human chorionic gonadotropin-stimulated progesterone output. Progesterone 137-149 oxytocin/neurophysin I prepropeptide Homo sapiens 26-34 3364500-7 1988 In the early luteal phase oxytocin (4 to 800 mU; 1 mU is equivalent to 2 ng) inhibited basal and human chorionic gonadotropin-stimulated progesterone production by dispersed luteal cells, but in the late luteal phase 200 to 800 mU oxytocin inhibited only human chorionic gonadotropin-stimulated progesterone output. Progesterone 295-307 oxytocin/neurophysin I prepropeptide Homo sapiens 26-34 3598299-4 1987 Oxytocin concentrations were correlated negatively with progesterone concentrations (Spearman"s rank correlation coefficient r = -0.50; P = 0.001).

Progesterone 62-74 oxytocin/neurophysin I prepropeptide Homo sapiens 4-12 3163000-11 1988 These results show that, under the influence of progesterone, oestradiol enhances the oxytocin-induced release of PGF-2 alpha, and suggest a possible synergistic action of these hormones for the induction of luteolysis in heifers. Progesterone 48-60 oxytocin/neurophysin I prepropeptide Homo sapiens 86-94 3963065-3 1986 Oxytocin concentrations in corpus luteum correlated significantly with estrone, estradiol, and progesterone.

Progesterone 113-125 oxytocin/neurophysin I prepropeptide Homo sapiens 0-8 3963065-8 1986 Our findings demonstrate that oxytocin is present and probably produced in corpus luteum and secreted into its ovarian vein; it may regulate corpus luteum release of progesterone, 17 alpha-hydroxyprogesterone, and estrone.
