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:The bovine endometrium secretes proteins across the estrous cycle that vary (in both protein identity and abundance) to be in synchrony with luminal reproductive events. To uncover the identity of these proteins, transcriptomics was performed to understand the secretory capability of the bovine endometrium through the distinct phases of the estrous cycle in cows. This dataset should serve as a baseline for understanding the profile of luminal secretory outputs across the estrous cycle, setting the stage for functional interpretation of how the uterus supports and directs biological events ranging from sperm transport to preimplantation embryo development.

Project description:We hypothesized that the gene expression pattern of OvHV-2 may be important to understand the pathogenesis of malignant catarrhal fever (MCF). Therefore, RNA was extracted from lymph nodes of animals with MCF and healthy controls to be analyzed by a custom-made microarray. Two regions on the viral genome were transcriptionally active, one encoding a homologue to the latency-associated nuclear antigen (ORF73) of other gamma herpesviruses, the other with no predicted open reading frame.
