Abstract
Maternal nutrients are essential for proper fetal and placental development and function. However, the effects of vitamin and mineral supplementation under two rates of maternal weight gain on placental genome-wide gene expression have not been investigated so far. Furthermore, biological processes and pathways in the placenta that act in response to early maternal nutrition are yet to be elucidated. Herein, we examined the impact of maternal vitamin and mineral supplementation (from pre-breeding to day 83 post-breeding) and two rates of gain during the first 83 days of pregnancy on the gene expression of placental caruncles (CAR; maternal placenta) and cotyledons (COT; fetal placenta) of crossbred Angus beef heifers. We identified 267 unique differentially expressed genes (DEG). Among the DEGs from CAR, we identified ACAT2, SREBF2, and HMGCCS1 that underlie the cholesterol biosynthesis pathway. Furthermore, the transcription factors PAX2 and PAX8 were over-represented in biological processes related to kidney organogenesis. The DEGs from COT included SLC2A1, SLC2A3, SLC27A4, and INSIG1. Our over-representation analysis retrieved biological processes related to nutrient transport and ion homeostasis, whereas the pathways included insulin secretion, PPAR signaling, and biosynthesis of amino acids. Vitamin and mineral supplementation and rate of gain were associated with changes in gene expression, biological processes, and KEGG pathways in beef cattle placental tissues.

Abstract
The major objective of this experiment was to determine whether the bovine placenta could be stimulated to secrete progesterone, since the bovine placenta secretes little progesterone when the corpus luteum is functional. Secondly, we wanted to determine whether reported abortifacients or progesterone or estrogen receptor antagonists affected bovine placental prostaglandin secretion. The ovine placenta secretes half of the circulating progesterone at day 90 of pregnancy and PGE2 appears to regulate ovine placental progesterone secretion. Calcium has been reported to regulate placental progesterone secretion in cattle. Diced 186-245-day placental slice explants from six Brahman and six Angus cows were incubated in vitro at 39.5 degrees C under 95% air: 5% CO2 at pH 7.2 in 5 ml of M-199 for 1 h in the absence of treatments and for 4 and 8 h in the presence of treatments. Treatments were: vehicle; R24571; compound 48/80; IP3; PGE2; CaCl2; cyclosporin A; lipopolysaccharide (endotoxin) from Salmonella abortus equi., enteriditis, and typhimurium; monensin; ionomycin; arachidonic acid; mimosine; palmitic acid; progesterone, androstenedione; estradiol-17beta; A23187; RU-486; or MER-25. Jugular and uterine venous plasma and culture media were analyzed for progesterone, PGE2 and PGF2alpha by radioimmunoassay (RIA). Plasma hormone data were analyzed by a One-Way Analysis of Variance (ANOVA). Hormone data in culture media were analyzed for breed and treatment effects by a Factorial Design (2 breeds, 2-range of days, 21 treatments) for ANOVA (2 x 2 x 21). Since hormone data secreted by placental tissue in vitro did not differ (P > or = 0.05) by breed or range of days of pregnancy, data were pooled and analyzed by a One-Way ANOVA. Concentrations of PGE2 in uterine venous blood were two-fold greater (P < or = 0.05) in Angus than Brahman cows. PGE2 and PGF2alpha in vehicle controls increased from 4 to 8h (P < or = 0.05), but not progesterone (P > or = 0.05) Progesterone in culture media treated with RU-486 increased (P < or = 0.05) at 4 and 8 h compared to vehicle controls and was not affected by other treatments (P > or = 0.05). Concentrations of PGE2 in media at 4 and 8 h were lower (P < or = 0.05) when compared to controls except treatment with PGE2 at 4 and 8h and RU-486 at 8h (P > or = 0.05). PGF2alpha was increased (P < or = 0.05) by RU-486 at 8h and no other treatment affected PGF2alpha at 4 or 8 h (P < or = 0.05). In conclusion, modulators of cellular calcium signalling pathways given alone do not affect bovine placental progesterone secretion at the days studied and progesterone receptor-mediated events appear to suppress placental progesterone, PGF2alpha, and PGE2 secretion in cattle. In addition, PGE2 does not appear to regulate bovine placental progesterone secretion when the corpus luteum is functional and bacterial endotoxin does not appear to affect bovine placental secretion of PGF2alpha or PGE2.

Abstract
Trophoblast giant cell differentiation is accompanied by transcriptional activation of the cytochrome P-450 side-chain cleavage (P450scc) gene. The Rcho-1 trophoblast cell line has the capacity to differentiate along the trophoblast giant cell lineage and has been used to study trophoblast-specific P450scc gene expression. In this report, P450scc gene promoter activities in trophoblast-specific P450scc gene expression. In this report, P450scc gene promoter activities in trophoblast cells have been mapped and the involvement of known modulators of steroid hydroxylase gene expression, the cyclic AMP/protein kinase A pathway and steroidogenic factor-1 (SF-1), evaluated. Comparisons were made with Y-1 adrenal and R2C Leydig cells. The cumulative results from transient and stable transfection experiments implicate the region between -428 and -511 bp of 5'-flanking DNA in the developmental activation of the P450scc promoter during trophoblast giant cell differentiation. Differences in basal activities of the P450scc promoter constructs were also observed in Y-1 adrenal and R2C Leydig cells; however, the magnitude of the differences was modest. Activators of the protein kinase A pathway stimulated P450scc promoter activity in Y-1 cells, whereas similar treatment of Rcho-1 trophoblast cells did not stimulate but actually inhibited P450scc promoter activity. The inhibitory activity was localized between -639 and -894 bp of the P450scc promoter. SF-1 mRNA and protein were detected in adrenal and gonadal cells but not in rat placenta or Rcho-1 trophoblast cells by Northern and Western blotting, respectively. Thus, P450scc gene activation during trophoblast cell differentiation involves an 83-bp region of its 5'-flanking DNA between -428 and -511 but does not appear to involve cyclic AMP-activated pathways or SF-1. In conclusion, the mechanism of P450scc gene activation during trophoblast cell differentiation appears different from the regulation of P450scc gene activation in other steroidogenic tissues.

Abstract
The hypothesis that placental secretion of progesterone (P4) and ovine placental lactogen (oPL) are controlled through different mechanisms was tested. Placental tissue was obtained at days 133-138 of pregnancy, and explant incubations were established using 200 mg tissue per flask in 5 ml O2-saturated DMEM containing 24 mM HEPES and lacking phenol red (pH 7.4). Following a 30-min preincubation, and a 15-min control period, test substances were added and incubations continued, with periodic gassing, for 4 h at 37 degrees C in a shaking water bath. Dopamine (DA), norepinephrine (NE) and epinephrine significantly stimulated P4 production (P less than 0.05). The enhancement of placental P4 production was mimicked by the addition of 8-bromo-cyclic adenosine monophosphate and forskolin (P less than 0.05). The response to catecholamines was abolished by the addition of propranolol (P less than 0.05) but not by phentolamine (P greater than 0.05). Inclusion of a membrane-permeant substrate for P4 synthesis, 25-hydroxycholesterol, increased basal (P less than 0.05) but did not enhance agonist-induced P4 production (P greater than 0.05). High performance liquid chromatographic analysis of placental tissue demonstrated the presence of DA (80.8 +/- 7.07 pg/mg) and NE (48.8 +/- 5.77 pg/mg), as well as catecholamine metabolites. Addition of 1,2-dioctanoyl-sn-glycerol (DAG) or phorbol 12-myristate-13-acetate (PMA) enhanced oPL secretion (P less than 0.05) without affecting P4 production. The response to DAG and PMA, representing the release of considerably more oPL than can be detected by extracting the tissue, was not influenced by treatment with cycloheximide (P greater than 0.05) indicating that secretion of preformed oPL is regulated by the protein kinase C pathway. These results support the hypothesis that the secretion of oPL and the production of P4 are controlled by different mechanisms.

Abstract
We have previously reported that progesterone synthesis in the bovine placenta is regulated by Ca2+ dependent and cyclic nucleotide independent mechanism. In studies conducted to further define the role of Ca2+ in the synthesis of progestins in bovine placental tissue, it was found that both protein kinase C (PKC), as determined by phosphorylation, and cytochrome P-450 side chain cleavage, as determined by Western blot analysis, were detectable in the steroidogenetically active portion of the placentome. To determine the site of action of PKC, fetal cotyledon cells were incubated in media containing 25-hydroxycholesterol in the absence or or presence of 10 ng/ml 12-O-tetradecanoyl-phorbol-13-acetate (TPA). It was found that TPA significantly (P less than 0.05) increased the conversion of the exogenous cholesterol analog to progesterone. To determine if the TPA could act synergistically with calcium activators, fetal cotyledon cells were incubated with either methyl isobutyl xanthine (MIX), an activator of intracellular calcium, or the calcium ionophore, A23187, which increases extracellular calcium influx, or both of these agents, in the presence or absence of TPA. It was found that TPA synergistically increased the conversion of sterol to progestins induced by submaximal concentrations of either MIX or A23187. In the presence of both compounds, TPA induced an even more dramatic increase in progestin synthesis. In experiments in which cyanoketone, an agent that inhibits the conversion of pregnenolone to progesterone, was added, TPA addition resulted in increased pregnenolone production, indicating that side chain cleavage of cholesterol is the site of action. The data, therefore, suggest that: (a) Ca2+ affects mechanisms regulating placental steroidogenesis; (2) one locus of Ca2+ is the cholesterol side chain cleavage reaction; and (3) PKC found in this tissue has a role in the Ca activated progestin production.
