Project description:To identify the molecular markers of early pregnancy in pigs, we compared global gene expression profiles of the maternal peripheral blood in pregnant sows with the non-pregnant sows. Peripheral blood sample was collected at 14 days after insemination from the submandibular vein of pregnant and non-pregnant sows respectively, and total RNA was isolated, purified and sent for microarray analysis. This study identified 127 up-regulated and 56 down-regulated genes (FC >= 1.5 and P < 0.05) in peripheral blood from pregnant sows versus non-pregnant sows. Of the differently expressed genes, nine (including LPAR3, RXFP4, GALP, CBR1, CBR2, GPX6, USP18, LHB and NR5A1) were found to exert function related to early pregnancy processes. Seven differentially expressed genes (CHGB, USP18, VWF, LPAR3, NR5A1, PPARD, BIN1) were selected to perform qRT-PCR in the same RNA samples.The expression profiles of these genes detected by qRT-PCR were consistent with those by microarray, which confirmed the reliability of our microarray data.

Project description:Large White and Meishan pigs were either non-treated or injected with mammalian 1-24 ACTH (Immediate Synachten, Novartis France) at the dose of 250 µg per animal. Pigs were sacrificed either immediately after capture from their home cage (non-treated animals) or 1 hour following ACTH injection. Adrenal glands were immediately collected from pigs and frozen on dry ice and then stored at -80°C until RNA isolation. Keywords: stress response, adrenal, gene expression, pig

Project description:To explore the influence of choline intake and pregnancy status on gene expression, we employed whole genome microarray expression profiling to identify genes that were differentially expressed between two choline intake groups and between pregnant and non-pregnant women. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d. Fasting peripheral blood leukocyte samples were collected at week 0 and week 12 to extract RNA and perform the arrays.

Project description:This study provide an opportunity to elucidate the genetic control of fetal implantation and improve our understanding of fetal implantation and gestation maintenance, thus make further improvement for litter size of pigs. Nine pregnant sows were slaughtered by electrical on day 13, day 18 and day 24 after insemination (the pregnant group, three sows every period). The non-pregnant sows were slaughtered on day 13 after inseminated (n=3).In pregnant sows, samples of the endometrium attachment sites and inter-sites were taken. Samples from the endometrium of the non-pregnant sows were taken from comparable locations.
