(Submitter supplied) The knowledge regarding the reproductive-status-related changes occurring within the transcriptome of the porcine pituitary is limited. This study aimed to compare pituitary gland gene expression profiles of pigs during the maternal recognition of pregnancy period (days 12-13 of pregnancy) with pigs during the respective days of the estrous cycle using a microarray approach. Analysis indicated 482 differentially expressed genes (DEGs) with a FC ≥ 1.5 (p < 0.05) in the pituitary of pregnant vs. estrous-cyclic pigs. more...

(Submitter supplied) In pigs, the peri-implantation period is recognized as determinant of successful reproduction, and it is controlled by neuroendocrinal interactions among signals originating from the female hypothalamic-pituitary-ovarian axis, uterus, and developing embryo. The transcriptomic activity of the pituitary gland may influence reproductive processes occurring in pigs during the peri-implantation period. The aim of this study was to determine alternations in gene expression in the porcine pituitary gland during the peri-implantation period (days 15-16 of pregnancy) in comparison with that during the respective days of the estrous cycle using a microarray approach.

(Submitter supplied) Several processes governing growth and metabolism are regulated by the neuroendocrine system, particularly the trophic hormones produced in the anterior pituitary gland. However, many of the differences that exist in pituitary gene expression and functional gene networks associated with divergent growth characteristics are still largely unknown. Using the Del-Mar 14K Chicken Integrated Systems microarray, this experiment evaluated global gene expression in the anterior pituitary gland during the first 7 weeks of post-hatch growth in two lines of chickens genetically selected for high growth (HG) or low growth (LG) at SRA-INRA, France. more...

(Submitter supplied) The porcine conceptus undergoes rapid differentiation and expansion of its trophoblastic membranes between Days 11 and 12 of gestation. Concomitant with trophoblast elongation, production of conceptus estrogen, the porcine embryonic pregnancy recognition signal increases. Conceptus attachment to the uterine surface epithelium starts after Day 13 initiating epitheliochorial placentation. To analyze the transcriptome changes in the endometrium in the course of maternal recognition of pregnancy (MRP), deep sequencing of endometrial RNA samples of Day 12 pregnant animals (n=4) and corresponding non-pregnant controls (n=4) was performed using Illumina RNA-Seq. more...

(Submitter supplied) We analyzed the transcriptome of the C57BL/6J mouse hypothalamus, hippocampus, neocortex, and cerebellum to determine estrous cycle-specific changes in these four brain regions. We found almost 16,000 genes are present in one or more of the brain areas but only 210 genes, ~1.3%, are significantly changed as a result of the estrous cycle. The hippocampus has the largest number of differentially expressed genes (DEGs) (82), followed by the neocortex (76), hypothalamus (63), and cerebellum (26). more...

(Submitter supplied) the aim of this present study was to characterize the complex transcriptome changes in different endometrial cell types during the preimplantation period for improving our understanding of localization of endometrial gene expression regulation in context of recognition of pregnancy. To do this analysis in a transcriptome-wide manner, RNA-seq was performed for samples derived from luminal epithelium (LE), glandular epithelium (GE), and stroma (S) isolated by the use of LCM

(Submitter supplied) The study allowed for the determination of the mRNAs that were differentially expressed in porcine endometrium on different gestational day and breed. The majority of the mRNAs were differentially expressed during the implantation stage. This study will provide the information to better understanding of the role of these differently expressed mRNAs in the porcine endometrium during pregnancy. Affymetrix mRNA arrays were used to generate mRNA profiles of on the endometrium of Meishan and Yorkshire pigs on days 15 (implantation stage), 26 (post-implantation stage) and 50 (mid-gestation stage) of gestation.

(Submitter supplied) The Chinese Erhualian is one of the most prolific pig breeds in the world, which farrows at least five more piglets per litter than Western pig breeds partly due to a greater ovulation rate. Differences in the transcriptome of Chinese Erhualian and Large White ovaries directly result in variation of ovulation rate. To understand the molecular basis related to ovulation rate in Chinese indigenous and Western breeds, samples were collected and used to hybridized. more...

(Submitter supplied) The pituitary gland is a neuroendocrine organ that is involved in several processes within the body such as metabolism, growth, immune function, and reproduction. Increased ambient temperatures are environmental stressor that leads to several welfare concerns in poultry production but also economic losses. Because of the involvement of the pituitary gland in several processes that are affected by heat stress, it is hypothesized this tissue's gene expression will be impacted by heat stress. more...

(Submitter supplied) Adiponectin is a hormone secreted primarily by white adipose tissue. Recent studies have shown that adiponectin and its receptors (AdipoR1 and AdipoR2) are expressed in different reproductive tissues, including the ovary and uterus. This newly discovered endocrine system plays an important role in the regulation of reproductive processes. The aim of this study was to explore the influence of adiponectin on global gene expression in the porcine endometrium during early gestation, on days 15 to 16 of pregnancy (implantation period).
