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:Purpose: Seminal fluid (SF) is considered as a regulator on environment establishing in female reproductive tract of various mammal species without mechanism elucidated completely. This study aimed to identified the function of exosome isolated from SF on porcine endometrium. Methods: Total RNA profiles of porcine endometrial epithelial cells with seminal exosomes treatment (EXO.) or not (CTRL.) were generated by deep sequencing, in triplicate, using HiSeq 2500. Trimmed sequences were analyzed on the basis of the TopHat/Cufflinks pipeline based on the porcine genome and reference annotations obtained from Ensembl genome browser (https://www.ensembl.org). Results: 10916 transcripts, from which 70 genes were up-regulated and 114 genes were down-regulated with q-values less than 0.05 in EECs with seminal exosome treatment compared to those without exosome treatment. Conclusions: Through the gene ontology (GO) biological process and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis which revealed significantly enriched or decreased molecular functions, Our work demonstrated that exosomes derived from porcine seminal fluid induced endometrial immune and inflammatory response via CCL20 and AMCFII regulation specifically, which may facilitate sperm cells survival and activation, and resulting in appropriate environment required for fertilization and even implantation.

Project description:To examine the effect of seminal fluid on the whole genome expression profile of endometrial tissue following mating, RNA was extracted from endometrial tissue collected 8 h after CBAF1 females were mated with intact Balb/c males and compared to RNA from endometrial tissue of females mated with seminal fluid deficient SVX/VAS Balb/c males. This comparison controlled for ovarian hormone status, exposure to the male and mating activity, and the neuroendocrine response to cervical and vaginal stimulus at mating, so that changes in endometrial gene expression could be attributed specifically to contact with seminal fluid. The endometrial RNA from n=16 individual females was pooled into four independent biological replicates per treatment group (n=4 endometrial samples per replicate) and expression profiles were analyzed by Affymetrix microarray. Seminal fluid exposure induced a clear difference in the profile of genes expressed in the endometrium with a total of 335 genes were differentially regulated with a fold-change greater than 1.5 and p<0.05. Of these, 190 genes were upregulated and 145 genes were downregulated following contact with seminal fluid. Bioinformatics analysis revealed TLR4 signaling as a strongly predicted upstream regulator activated by the differentially expressed genes.Additional experiments confirmed the role of TLR4 with the absence of TLR4 in TLR4 null mice resulting in a failure for seminal fluid to induce endometrial Csf3, Cxcl2, Il6 and Tnf expression. This study provides evidence that TLR4 contributes to seminal fluid modulation of the periconception immune environment. Activation of TLR4 signaling by microbial or endogenous components of seminal fluid is thus implicated as a key element of the female tract response to seminal fluid at the outset of pregnancy in mice.

Endometrial RNA collected 8 h following coitus from n=16 individual females was pooled into four independent biological replicates per treatment group (n=4 endometrial samples per replicate) and expression profiles were analyzed by Affymetrix microarray. Microarray analysis was performed using Affymetrix Mouse Gene 2.0 ST Arrays at the Adelaide Microarray Centre (Adelaide, Australia). Total RNA (300 ng) was labelled using the GeneChip® WT PLUS Reagent Kit according to the manufacturer’s instructions (Affymetrix, Santa Clara, CA). Microarray data was analyzed using Partek Genomics Suite version 6.6). Briefly, .cel files were imported using RMA background correction, following GC content correction and mean probe summarization. Differentially expressed probes were defined as ≥1.50-fold change, t-test p <0.05. To investigate gene pathways and upstream regulators activated by seminal fluid following mating, differentially expressed genes were analyzed using Ingenuity Pathway Analysis (IPA) version 18488943 Build 308606M (IPA, Ingenuity Systems, Redwood City, CA).

Project description:Embryo implantation into maternal endometrium is critical for initiation and establishment of pregnancy, requiring developmental synchrony between endometrium and blastocyst. However, factors regulating human endometrial-embryo cross talk and facilitate implantation remain largely unknown. Extracellular vesicles (EVs) are emerging as important mediators of this process. Here, human trophectomderm stem cell-derived EVs were shown to transfer to and regulate human endometrial cells towards processes associated with implantation. Importantly, transfer of trophectoderm EV cargo proteins to endometrial cells to mediate changes in polarity is demonstrated.

Project description:The seminal plasma (sp), especially the extracellular vesicles of seminal plasma (sEV) which change with age can affect the endometrial immune microenvironment of female mice. However, it is unclear whether the decline in fertility of reproductively old males is related to the alterations of the sp and sEV which may have compromised effect on the immune microenvironment of the female uterus. In this research, we found a decrease in the implantation rate of pseudo-pregnant female mice which was treated with sp from reproductively old male mice (aged-sp group) than sp from young male mice (young-sp group). RNA-sequence analysis revealed an increase in the expression level of local cytokines and chemokines in the uterus of aged-sp groups than those of young-sp groups. Further in vitro experiments found an induction of dendritic cells (DC) maturation in the aged-sp groups. After isolating and characterizing sEV in young and aged male mice, we perfused the uterus of aged-sp group with sEV from young male mice and found it could partially rescue the low implantation rate of the aged-sp group. Further in vitro experiments found an induction of DC maturation after treating with sEV from aged male mice than that from young male mice, which indicated an age-related activation effect of sp and sEV. In conclusion, we found sp and sEV from aged male mice could induce the maturation of DC, which compromised the microenvironment of female reproductive tract, therefore leading to a decrease in implantation rate.

Project description:Endometrial receptivity plays a vital role in the success of embryo implantation. However, the temporal proteomic profile of porcine endometrium during embryo implantation is still unclear. In this study, the expression of proteins in endometrium on days 9, 10, 11, 12, 13, 14, 15 and 18 of pregnancy (D9, 10, 11, 12, 13, 14, 15 and 18) was profiled via iTRAQ technology. The results showed that 25, 55, 103, 91, 100, 120, 149 proteins were up-regulated, and 24, 70, 169, 159, 164, 161, 198 proteins were down-regulated in porcine endometrium on D10, 11, 12, 13, 14, 15 and 18 compared with that on D9, respectively. Among these differentially expressed (DE) proteins, MQM results indicated that S100A9, S100A12, HRG and IFI6 were differentially expressed in endometrial tissues during embryo implantation period. Bioinformatics analysis showed that the proteins differentially expressed in the 8 comparisons (D10 vs D9, D11 vs D9, D12 vs D9, D13 vs D9, D14 vs D9, D15 vs D9 and D18 vs D9) were involved in important processes and pathways related to immunization, endometrial remodeling, which have a vital effect on embryonic implantation. Our results reveal that RBP4 could regulate the cell proliferation, migration and apoptosis of endometrial epithelial cells and endometrial stromal cells to affect embryo implantation. This research also provides resources for studies of proteins in endometrium during early pregnancy.

Project description:Although piwi-interacting RNAs (piRNAs) play pivotal roles in spermatogenesis, little is known about piRNAs in the seminal plasma of infertile males. In this study, we systematically investigated the profiles of seminal plasma piRNAs in infertile males to identify piRNAs that are altered during infertility and evaluate their diagnostic value. Seminal plasma samples were obtained from 211 infertile patients (asthenozoospermia and azoospermia) and 91 fertile controls. High-throughput sequencing technology was employed to screen piRNA profiles in seminal plasma samples pooled from healthy controls and infertile patients. The results identified 61 markedly altered piRNAs in the infertile patient groups compared with the control group. Next, a quantitative RT-PCR assay was conducted in the training and validation sets to measure and confirm the concentrations of altered piRNAs. The results identified a panel of 5 piRNAs that were significantly decreased in the seminal plasma of infertile patients compared with healthy controls. The areas under the ROC curves for these piRNAs ranged from 0.796 to 0.996, suggesting that the diagnostic potential of these 5 piRNAs to distinguish asthenozoospermic and azoospermic individuals from healthy controls was high. In summary, this study identifies a panel of piRNAs that can accurately distinguish fertile from infertile males. This finding may provide pathophysiological clues that are involved in the development of infertility. Fresh samples were collected and stored at -80â??.Total RNA of seminal plasma were extracted and solexa sequencing was performed.
