Project description:Cumulus cells surrounding mature oocytes that developed to moruale/blastocyst stage on day 5 of IVF cycle were collected and used for gene expression profiling using Affymetrix Human Gene 1.0 ST Arrays in order to determine differences in gene expression between the modified natural and stimulated in vitro fertilization (IVF) procedures.

Project description:Our study reported an increased risk of metabolic disorders in in-vitro Fertilization and Frozen-thawed Embryo Transfer (IVF-FET) conceived offspring compared with those born after IVF-ET. To explore the underlying mechanisms of the aberrant metabolism in male offspring conceived by IVF and FET compared with natural conceived (NC), we performed the RNA-sequencing of livers from three groups. We performed GSEA analysis. The results suggested more severe alterations in the expression of genes involved in insulin resistance pathway in the FET-chow group than that in the IVF-chow group.

Project description:To compare the expression levels of long non-coding RNA (lncRNA) and messenger RNA (mRNA) in endometrium between patients with Polycystic Ovary Syndrome （PCOS）and normal ovulation undergoing in vitro fertilization-embryo transfer (IVF-ET） LncRNAs and mRNAs of endometrium were identified via RNA sequencing from 3 PCOS and 3 normal ovulation

Project description:Cumulus cells surrounding mature oocytes that developed to moruale/blastocyst stage on day 5 of IVF cycle were collected and used for gene expression profiling using Affymetrix Human Gene 1.0 ST Arrays in order to determine differences in gene expression between the modified natural and stimulated in vitro fertilization (IVF) procedures. Microarray analysis was made on 8 individual CC samples, derived from 5 patients that first underwent MNIVF, followed by a controlled ovarian hyperstimulation (COH) cycle. As the quality of the isolated RNA derived from 2 of the MNIVF CC samples was not good, these samples were not included in the analysis. Altogether, 3 CC samples from MNIVF and 5 CC samples from COH cycles were included in microarray analysis.

Project description:Clinical treatment protocols for infertility with in vitro fertilization-embryo transfer (IVF-ET) provide a unique opportunity to assess the human vaginal microbiome in defined hormonal milieu. Herein, we have investigated the association of circulating ovarian-derived estradiol (E2) and progesterone (P4) concentrations to the vaginal microbiome. Thirty IVF-ET patients were enrolled in this study, after informed consent. Blood was drawn at four time points during the IVF-ET procedure. In addition, if a pregnancy resulted, blood was drawn at 4-to-6 weeks of gestation. The serum concentrations of E2 and P4 were measured. Vaginal swabs were obtained in different hormonal milieu. Two independent genome-based technologies (and the second assayed in two different ways) were employed to identify the vaginal microbes. The vaginal microbiome underwent a transition with a decrease in E2 (and/or a decrease in P4). Novel bacteria were found in the vagina of 33% of the women undergoing IVF-ET. Our approach has enabled the discovery of novel, previously unidentified bacterial species in the human vagina in different hormonal milieu. While the relationship of hormone concentration and vaginal microbes was found to be complex, the data support a shift in the microbiome of the human vagina during IVF-ET therapy using standard protocols. The data also set the foundation for further studies examining correlations between IVF-ET outcome and the vaginal microbiome within a larger study population.

Project description:ObjectiveThe aim of this meta-analysis is to explore the beneficial role of granulocyte colony-stimulating factor (G-CSF) on infertile women under artificial reproduction technology treatment.MethodMedline, Embase and ISI Web of Science databases were searched to identify relevant randomized control trials. Studies before July, 2017 were included for primary screening. Meta-analysis of the total and subgroup patients was conducted, and relative risks (RRs) and their 95% confidence intervals (95% CI) were calculated by a fixed-effect model if no heterogeneity (evaluated as I2 statistic) existed. Otherwise, a random-effects model was adopted. Subgroup analysis was performed by administrating route or clinical indication. Egger test and influence analysis were conducted to evaluate the publication bias and study power, respectively.ResultsThe final selection enrolled 10 RCTs, involving 1016 IVF-ET cycles (521 distributed to the G-CSF group and 495 to the control). Compared with control group, G-CSF administration could significantly improve clinical pregnancy rate (CPR, RR 1.89, 95% CI 1.53-2.33), while it had no beneficial effect on embryo implantation rate (IR, RR 1.84, 95% CI 0.84-4.03). The subgroup analysis by administration route showed that both uterine infusion and subcutaneous injection can produce a substantial increase in CPR, with the pooled RRs (95% CI) 1.46 (1.04-2.05) and 2.23 (1.68-2.95), respectively. Nevertheless, most of included RCTs dealt with the RIF subjects, and the pooled analysis of this data showed a higher PR and IR in G-CSF group as compared to that in the control, with the RRs (95% CI) 2.07 (1.64-2.61) and 1.52 (1.08-2.14), respectively. Egger regression test did not demonstrate any significance for the publication bias.ConclusionG-CSF administration has a beneficial role on the clinical outcome after embryo transfer by both routes of local infusion and systematic administration, especially for the cases with RIF. Further RCTs are needed to investigate the role of G-CSF in thin endometrium patients.

Project description:In vitro production (IVP) has been shown to affect embryonic gene expression and often result in large offspring syndrome (LOS) in cattle and sheep. To dissect the effects of in vitro maturation, fertilization and culture, we compared the expression profiles of single bovine blastocysts generated by: 1) in vitro maturation, fertilization and culture (IVF); 2) in vivo maturation, fertilization and in vitro culture (IVD); and 3) in vivo maturation, fertilization and development (AI). To conduct expression profiling, total RNA was isolated from individual embryos, linearly amplified and hybridized to a custom bovine cDNA microarray containing approximately 6,300 unique genes. There were 306, 367 and 200 genes differentially expressed between the AI and IVD, IVF and IVD and AI and IVF comparisons, respectively. Interestingly, 44 differentially expressed genes were identified between the AI embryos and both the IVF and IVD embryos, making these potential candidates for LOS. There were 60 genes differentially expressed between the IVF embryos and the AI and IVD embryos. The Gene Ontology category “RNA processing” was over-represented among the genes that were down-regulated in the IVF embryos, indicating an effect of in vitro oocyte maturation/fertilization on embryonic gene expression. A culture effect on the expression of genes involved in translation was also observed by the comparison of AI to IVD embryos. Keywords: developmental condition
