Project description:The objective of this study was to examine the effect of the presence of a single or multiple embryo(s) on the transcriptome of the bovine oviduct. In Experiment 1, cyclic (non-bred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells from the isthmus region, in which all oocytes/embryos were located, were snap-frozen for microarray analysis. In Experiment 2, heifers were divided into cyclic (non-bred, n = 6) or pregnant (multiple embryo transfer, n = 10) groups. In vitro-produced presumptive zygotes were transferred endoscopically to the ipsilateral oviduct on Day 1.5 post estrus (n = 50 zygotes per heifer). Heifers were slaughtered on Day 3 and oviductal isthmus epithelial cells were recovered for RNA sequencing. Microarray analysis in Experiment 1 failed to detect any difference in the transcriptome of the oviductal isthmus induced by the presence of a single embryo. In Experiment 2, following multiple embryo transfer, RNA sequencing revealed 278 differentially expressed genes of which 123 were up- and 155 were down-regulated in pregnant heifers. Most of the down-regulated genes were related to immune function.

Transcriptional profiles of oviductal isthmus epithelial cells from cyclic and pregnant heifers were generated by sequencing of total RNA on the Illumina HiSeq 2500 platform

In experiment 2, heifers were divided into cyclic (nonbred, n = 6) or pregnant (multiple embryo transfer, n = 10) groups. In vitro-produced presumptive zygotes were transferred endoscopically to the ipsilateral oviduct on Day 1.5 postestrus (n = 50 zygotes/heifer). Heifers were slaughtered on Day 3, and oviductal isthmus epithelial cells were recovered for RNA sequencing. Microarray analysis in experiment 1 failed to detect any difference in the transcriptome of the oviductal isthmus induced by the presence of a single embryo. In experiment 2, following multiple embryo transfer, RNA sequencing revealed 278 differentially expressed genes, of which 123 were up-regulated and 155 were down-regulated in pregnant heifers. Most of the down-regulated genes were related to immune function. In conclusion, the presence of multiple embryos in the oviduct resulted in the detection of differentially expressed genes in the oviductal isthmus; failure to detect changes in the oviduct transcriptome in the presence of a single embryo may be due to the effect being local and undetectable under the conditions of this study.

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.
