Project description:Here we tested the hypothesis that intrauterine infusion of pathogenic bacteria leads to changes in the transcriptome of the reproductive tract in dairy cattle three months later. We used virgin Holstein heifers to avoid the confounding effects of periparturient problems, metabolic stress and lactation. Animals were infused intrauterine with endometrial pathogenic bacteria Escherichia coli and Trueperella pyogenes to induce clinical endometritis (n = 4) and compared with control animals (n = 6). Three months after infusion, the caruncular and intercaruncular endometrium, isthmus and ampulla of the oviduct, and granulosa cells from dominant ovarian follicles were profiled by RNA-sequencing. Compared with control, bacterial infusion altered the transcriptome of all the tissues. Most differentially expressed genes were tissue-specific, with 109 differentially expressed genes unique to the caruncular endometrium, 57 in the intercaruncular endometrium, 65 in the isthmus, 298 in the ampulla, and 83 in granulosa cells. Surprisingly, despite infusing the bacteria into the uterus, the granulosa cells had more predicted upstream regulators of differentially expressed genes than all the other tissues combined. In conclusion, there was evidence of long-term changes to the transcriptome of the endometrium, oviduct and even the granulosa cells after intrauterine infusion of pathogenic bacteria, which implies that all these tissues contribute to the infertility that persists after endometritis.

Project description:The underlying genomic regulation of the tissue synchronization is poorly understood. To understand this better we investigated the transcriptomes of the porcine ovary, endometrium, and oviduct at days 0, 3, 6, 9, 12, 15, or 18 of the oestrous cycle. We analysed the transcriptome profiles of the individual tissues.

Project description:The endometrium provides optimal conditions for the transport of sperm to the oviduct, to the site of fertilization, and later on for the reception of the embryo. To study these changes on the level of gene expression, a messenger RNA expression profiling of endometrium tissue samples collected from 19 cyclic heifers at five stages of the estrous cycle (days 0, 3.5, 12, 18, 20) was performed. RNA was extracted from these tissue samples and analyzed with a custom-made bovine oviduct and endometrium (BOE) cDNA array. The cDNAs present on the array were derived from several previously conducted differential gene expression studies of bovine endometrium between different stages of the estrous cycle, during early pregnancy, and from studies of bovine oviduct epithelial cells. In all of these studies cDNAs of differentially expressed genes were identified using a combination of subtracted cDNA libraries and cDNA array hybridization. 1,440 cDNA fragments are located on the array. Twenty radioactively labeled cDNA samples (n=4 for each cycle stage) were hybridized with BOE arrays. Raw data were normalized using the BioConductor package vsn.

Keywords: time course of gene expression in bovine endometrium during estrous cycle Nineteen German Fleckvieh (Simmental) heifers were slaughtered at four different days of the estrous cycle, four animals at day 0, four at day 3.5, three at day 12 and eight animals at day 18. Four of the day 18 animals showed high and the other four low serum progesterone (P4) levels, respectively. This resulted in five groups of endometrial tissue samples corresponding to five stages of the estrous cycle.

Project description:Combining the cytological as well as gene expression changes in the endometrium is required to understand the effects of subclinical endometritis on endometrium as well as embryo. Hence, the present study was aimed to investigate the gene expression profiles of subclinical endometrium as well the effect of the inflamed environment on the gene expression profile of the developing preimplantative embryo. Endometrial samples were collected from each 49 cow using the cytobrush technique, 2 h before insemination (Day 0 of the estrous cycle after superovulation) and immediately before flushing (Day 7 of the estrous cycle after superovulation). The endometrial samples were categorized based on the PMN value as healthy endometrium (HE, PMN = 0) and subclinical endometritis (SE, endometrial PMN > 0). Flushed embryos were snap frozen for later molecular genetic analysis. Finally, endometrial samples were pooled according to the endometrial health status of the donor cows (HE vs. SE) at the time of insemination and at the time of flushing. The corresponding samples were subjected global gene expression profile. Moreover embryos flushed from HE and SE cows were pooled together according to the health status of their donors at time of flushing. Those embryos were also used for global embryonic gene expression analysis in relation to the health status of the donor cows.

Project description:Although the oviduct and uterus regulate early embryonic development, understanding of the specific maternally-derived molecules that signal to the embryo is incomplete. Objectives of this study were to characterize expression of genes encoding for growth factors, cytokines, and other cell-signaling ligands in the endosalpinx and endometrium of the bovine female and analyze spatial changes in gene expression throughout the reproductive tract.

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.

Project description:Our results indicated that conditional knockout of Cdc42 in the epithelial cells of the oviduct isthmus led to defective embryo transport, resulting in blastocytes retention in oviduct, and contributing to the pregnancy failure in PgrCreCdc42f/f mice. To further determine the role of CDC42 in oviduct, RNA-seq analysis was applied in the Cdc42f/f and PgrCreCdc42f/f mice oviduct on day 2 of pregnancy.
