Project description:Sperms being foreign to the female are to be promptly eliminated by the female local immune defense. However, avoiding the local immune defense sperm can be stored for lenthy period in the oviductal sperm reservoir. It is currently unknown whether oviductal sperm reservoirs changes their gene expression to tolerate the spermatozoa after mating or sperm free seminal plasma infusion. Therefore this was tested using Swedish Landrace pigs in this study using cDNA microarray. We used 12 sows seperated into three groups- either oestrus sows were inseminated with 50 ml BTS (control, n=4) or mated with boars (treatment 1, n=4) or inseminated with sperm-free seminal plasma (treatment 2, n=4). The utero-tubal junction was retrieved within 24 h of treatment by operation.

Project description:The seminal plasma (SP) is the liquid component of semen that facilitates sperm transport through the female genital tract. SP modulates the activity of the ovary, oviductal environment and uterine function during the periovulatory and early pregnancy period. Extracellular vesicles (EVs) secreted in the oviduct (oEVs) and uterus (uEVs) have been shown to influence the expression of endometrial genes that regulate fertilization and early embryo development. In some species, semen is composed of well-separated fractions that vary in concentration of spermatozoa and SP composition and volume. This study aimed to investigate the impact of different accumulative fractions of the porcine ejaculate (F1, composed of the sperm-rich fraction (SRF); F2, composed of F1 plus the intermediate fraction; F3, composed of F2 plus the post-SRF) on oEVs and uEVs protein cargo. Six days after the onset of estrus, we determined the oEVs and uEVs size and protein concentration in pregnant sows by artificial insemination (AI-sows) and in non-inseminated sows as control (C-sows). We also identified the main proteins in oEVs and uEVs, in AI-F1, AI-F2, AI-F3, and C-sows. Our results indicated that although the size of EVs is similar between AI- and C-sows, the protein concentration of both oEVs and uEVs was significantly lower in AI-sows (p < 0.05). Proteomic analysis identified 38 unique proteins in oEVs from AI-sows, mainly involved in protein stabilization, glycolytic and carbohydrate processes. The uEVs from AI-sows showed the presence of 43 unique proteins, including already-known fertility-related proteins (EZR, HSPAA901, PDS). We also demonstrated that the protein composition of oEVs and uEVs differed depending on the seminal fraction(s) inseminated (F1, F2, or F3). In conclusion, we have found a specific protein cargo in uterine and oviductal EVs depending on the type of semen fraction the sow was inseminated with, and these insemination with different seminal fractions results in the oviductal and uterine secretion of specific EVs proteins are closely associated with reproductive processes.

Project description:The seminal plasma contains large quantities of extracellular vesicles (EVs). However, the role of these EVs and their interactions with sperms are not clear. To identify the important molecules affecting sperm motility in EVs, we sequenced the EVs in the seminal plasma of Yorkshire boars with different sperm motility using whole RNA sequence.

Project description:Seminal plasma (SP) promotes sperm survival and fertilizing capacity, but also potentially affects embryo development presumably via specific signaling to the internal genital tract. This study evaluated how heterologous SP, infused shortly before post-cervical artificial insemination (AI) affected the transcriptional pattern of the pig endometrium and embryo development rates. Post-weaning estrus sows (n= 34) received 40-mL intrauterine infusions of either heterologous pooled SP or BTS (Control) 30 minutes before AI of semen extended to 10% of homologous SP. Embryos (all sows) and endometrium samples (3 sows/group) were removed by laparotomy at day 6 after SP or BTS infusions to morphologically evaluate embryo developmental staging and the endometrial transcriptome via microarrays (PORGENE 1.0 ST GeneChip array, Affymetrix), validated by qPCR. Embryo viability was equal between groups (~93%), but embryos were significantly (P<0.05) more advanced (full/peri-hatching blastocysts) in the SP-treated group compared to control. A total of 1,604 endometrium transcripts were differentially expressed in the SP group compared to controls. An enrichment analysis depicted an overrepresentation of genes and pathways associated with immune response, cytokine signaling, cell cycle, cell adhesion, and hormone response, among others. SP-infusions prior to AI positive impacted pre-implantation embryo development by altering endometrial genes and pathways potentially involved in embryo development.

Project description:EVs are known to contain important cargo of biologically active and regulatory molecules including ncRNAs. EVs in seminal plasma, play an important role in sperm functions , including motility and fertilization. However, less is known about the comprehensive profile of spEV ncRNAs in clinical cohort and if these profiles differ by semen quality status. We assessed sperm-free spEV ncRNA profiles from semen samples of male partners receiving IVF treatment. Men were classified into having normal (n = 59, Status 0) or poor (n = 32, Status 1) semen quality based on WHO semen parameter guidelines.
