Seminal plasma modulates the immune-cytokine network in the porcine uterine tissue and pre-ovulatory follicles.

ABSTRACT: Evidence is emerging that the interaction between male seminal fluid and female tissues promotes fertility, pregnancy, and health of offspring. This includes the acceleration of ovulation in a species known as a spontaneous ovulator, the domestic pig. Earlier studies revealed that seminal plasma acts by a local mechanism in the female pig. The aim of the present study was to examine local short-term and mid-term effects of seminal plasma (SP) on mRNA expression of immunoregulatory genes and transcripts associated with follicle- and oocyte maturation. In the porcine animal model, effects on mRNA expression in the female tract and preovulatory follicles were examined. SP suppressed mRNA expression of Prostaglandin-Endoperoxide Synthase 2 (PTGS2) ipsilateral to the infused uterine horn which was associated with a lower presence of immune cells in the uterine epithelium and lower PTGS2 immunoreaction. Depending on the sampling time (2 h vs. 17 h) and hormonal status, SP altered significant correlative relations of mRNA expression between PTGS2 and the transcripts Tumor Necrosis Factor Alpha, Tumor Necrosis Factor Alpha-Induced Protein 6 and Pentraxin 3 in uterus, granulosa and cumulus cells. A modulatory effect of SP on the oocyte gene network comprising eight oocyte transcripts was observed: uterine exposure to SP induced positive correlations (r >0.08, p<0.05) of maturation promoting factors among each other and with cumulus cells on the side of the treated horn. In conclusion, SP orchestrates the gene network regulating the bidirectional communication between oocytes and surrounding somatic cells. The modulation of the immune-cytokine network of the female reproductive system could contribute to the previously reported SP-induced acceleration of ovulation in the porcine species.

Project description:Purpouse: Aims of this study were (1) to characterize the endometrial transcriptome, (2) to identify functional pathways, and (3) to molecularly characterize selected pathways overrepresented in the endometrium of day 7 post-ovulation induction of cows treated to ovulate larger versus smaller follicles Methods: Seventy-four multiparous, nonlactating, presynchronized Nelore cows received a progesterone-releasing device and estradiol benzoate on Day–10 (D?10). Animals received cloprostenol (large follicle-large CL group; LF-LCL; N = 35) or not (small follicle-small CL group; SF-SCL; N = 39) on D?10. Progesterone devices were withdrawn and cloprostenol administered 42 to 54 hours (LF-LCL) or 30 to 36 hours (SF-SCL) before GnRH treatment (D0). Tissues were collected at slaughter on D7. Transcriptional profiling of the endometrial tissue was performed by RNA-seq and protein markers for proliferation and apoptosis were identified by immunohistochemistry. Results: Functional enrichment data indicated that LF-LCL endometrium expressed greater abundance of genes associated with biosynthetic and metabolic processes, whereas SF-SCL endometrium .gene expression profile was biased towards cell proliferation. Extracellular matrix-related genes were also upregulated in the SF-SCL endometrium suggesting reorganization of the ECM towards a proliferation permissive phenotype. Immunohistochemistry data confirmed the greater proliferative activity observed in SF-SCL endometrium I comparison to LF-LCL counterparts, and indicated a time-related transition within experimental group. In conclusion, the periovulatory endocrine milieu regulates bovine endometrial gene expression. Furthermore, timing and amplitude of ovarian steroid secretion pattern seem to determine the transition from a proliferation permissive to a biosynthetic and metabolically active endometrial phenotype, which may be associated with the preparation of an optimally receptive uterine environment. Conclusion: the periovulatory endocrine milieu affected D7 endometrial molecular signature. Main pathways affected were related to cell proliferation, ECM composition and remodeling, biosynthetic and metabolic processes. Reported data further suggest that the endometrial tissue from LF-LCL cows experienced an early proliferative phase (D4), whereas the SF-SCL endometrium, exposed to a distinct periovulatory endocrine environment, expressed a delayed onset of the proliferative activity (D7). endometrial mRNA profiles of endocrine manipulated cows were generated by deep sequencing using Illumina HiScanSQ platform
