Exosome miRNA expression in umbilical cord blood of high-parity piglets reveals the reproductive potential of sows

Project description:The objective of modern pig breeding is to exhaust the genetic potential in reproduction performance of sows regarding to litter size and litter weight of piglets. During gestation period, umbilical cord contributes to placenta-fetal communication and plays an indispensable role in the intrauterine embryonic development. In this study, we attempted to analyze the molecular mechanism of reproductive declined in high-parity sows from the perspective of umbilical cord blood. Firstly, we analyzed the reproductive character data of sows, and then the histological analysis of umbilical cord phenotype was performed. Next, we evaluated the effect of umbilical cord blood exosomes (UCB-EXO) on angiogenesis. Moreover, the expression characteristics of miRNA in UCB-EXO of high-parity sows with poor reproductive performance (OS) and multiparous sows with excellent reproductive performance (MS) were analyzed. Results showed that the reproductive performance performed best at 3rd-7th and gradually decreased after 8th parities. Angiogenesis was repressed in OS piglets. Moreover, the Exo-MS exhibited pro-angiogenesis properties, with those of Exo-OS were diminished. With the increase of parities, the angiogenesis and immune function of sows decreased significantly, greatly limited the reproductive potential of sows. The data demonstrated that miRNAs of UCB-EXO played a central role in intrauterine development and suggested a novel possible explanation for reproductive potential, provides reference for increasing female reproductive efficiency.

Maternal antibiotic use in sows affects microbiota and gut development in offspring

Project description:We demonstrated that a maternal antibiotic treatment can change intestinal development of the offspring piglets permanently by showing that maternal gestational antibiotic treatment affects intestinal development in offspring piglets for a period of at least seven weeks after the antibiotic treatment in the sows was finished. It was shown that immediately after birth the piglets from amoxicillin treated sows, showed upregulation of genes involved in processes related to ‘tight junctions’ and ‘immunoglobulins’. In addition, these piglets had significantly lower number of goblet cells. Together, this may lead to a gut wall that is more rapidly closed in piglets from amoxicillin treated sows, affecting the uptake of immunoglobulins and the intestinal development. Later in life, around weaning, gene expression and morphological data indicate that the crypts of piglets from amoxicillin treated sows deepen around weaning as an effect of the amoxicillin treatment which in combination with the upregulation of genes involved in cell cycle processes, ribosomal activity and protein degradation might imply that the intestinal development, the subsequent differentiation of cells or the timing of these processes was delayed by the maternal antibiotic treatment.

Transcriptome profiling of ovarian tissues from pigs with extreme phenotypes for reproductive efficiency during the luteal and follicular phases of the estrous cycle

Project description:Purpose:The goal of this study was to enrich understanding of the reproductive difference Methods:Multiparous Canadian Large White cyclic sows were divided into two parts: high (H; total number of piglets born > 15.73) and low (L; total number of piglets born < 11.11) fecundity. Eight sows with similar parity from each part were chosen (n=16). Ovarian tissues were obtained on the 14 day (day 1 = first day of estrus) after estrus as in the luteal phase (L) and 20 day of the estrous cycle as in the follicular phase (F). Transcriptome profiling of ovarian tissues were generated by deep sequencing, in quadruplicate, using Illumina HiSeq X10 instrument. Results: Using an optimized data analysis workflow, we obtained the differentially expressed RNAs between the high and low fecundity, with a fold change ≥1.5 and p value < 0.05. These results provide further insight into fecundity in pigs. Conclusions: Our study represents the first detailed analysis of ovary transcriptome. It will be significantly helpful to display a novel regulatory mechanism for further investigation of prolificacy in pigs.

Expression data from uterus of high vs low prolificacy Iberian x Meishan F2 sows at 30-32 days of gestation

Project description:An F2 cross between two highly divergent porcine breeds for most productive traits, including prolificacy, was generated. F2 sows were classified as of high or low prolificacy based on phenotypic records of four consecutive parities (total number of piglets born and number of piglets born alive were recorded). At the fifth gestation, sows were slaughtered at day 30-32 of gestation, and the number of corpora lutea and number of embryos were registered. Samples from different tissues were snap frozen in liquid nitrogen for further studies. Uterus samples were used for total RNA extraction and hybridized on the affymetrix porcine genechip for comparison between high and low prolificacy F2 sows.

Intermittent suckling does not influence the gene expression of Day 9 embryos during early gestation in primiparous sows

Project description:Primiparous sows were randomly allocated to two treatments and were separated from piglets 8h daily from Day 21 of lactation companied with daily boar exposure for oestrus detection until weaning (Day 28). Gene expression of Day 9 embryos were compared between control sows (FE; sows artificially inseminated when in heat during lactation ) and Skip-a-Heat sows (SE; sows in heat during lactation and artificially inseminated on the following oestrus cycle). Stimulating lactational oestrus then two mating strategies were applied to primiparous sows; 1)FE; sows were in heat during lactation and received artificial insemination) and Skip-a-Heat sows (SE; sows were in heat during lactation and received artificial insemination at fallowing oestrus cycle).

Detection of differentially expressed genes in Day 30 embryos during gestation in primiparous (PP) sow with different intermittent suckling and breeding strategies

Project description:Transcriptional profiling of Day 30 embryos (D30E) was performed. First parity sows were submitted to an ovulation-induction protocol, intermittent suckling (IS), during lactation. IS consisted of 8 h/d separation from their litters during the last 7d of a 28d lactation. During separation, sows received boar exposure. There were 3 treatments: control (C28, n=19), where piglets were weaned at D28 of lactation and were bred after weaning and two IS treatments: sows were either bred at their first induced estrus during lactation (IS21FE, n=18), or were “skipped” and bred at their second estrus (IS21SE, n= 17) which occurred after final weaning at D28. Sows were slaughtered and embryos were collected on D30 of gestation for DNA PCR sexing. Later, D30E from the same sex with similar weight were pooled for further microarray investigation.

Differiential gene expression profiling in peripheral blood between pregnant sows versus non-pregnant sows

Project description:To identify the molecular markers of early pregnancy in pigs, we compared global gene expression profiles of the maternal peripheral blood in pregnant sows with the non-pregnant sows. Peripheral blood sample was collected at 14 days after insemination from the submandibular vein of pregnant and non-pregnant sows respectively, and total RNA was isolated, purified and sent for microarray analysis. This study identified 127 up-regulated and 56 down-regulated genes (FC >= 1.5 and P < 0.05) in peripheral blood from pregnant sows versus non-pregnant sows. Of the differently expressed genes, nine (including LPAR3, RXFP4, GALP, CBR1, CBR2, GPX6, USP18, LHB and NR5A1) were found to exert function related to early pregnancy processes. Seven differentially expressed genes (CHGB, USP18, VWF, LPAR3, NR5A1, PPARD, BIN1) were selected to perform qRT-PCR in the same RNA samples.The expression profiles of these genes detected by qRT-PCR were consistent with those by microarray, which confirmed the reliability of our microarray data.
