LncRNA affects epigenetic reprogramming of porcine embryo development by regulating global epigenetic modification

Project description:The key lncRNAs that regulate embryo development were screened through analyzing expression pattern of lncRNA in porcine in vivo fertilization (IVV) embryos. By knocking down lncRNA expression in in vitro fertilization (IVF) embryos, we investigated its function and mechanism of regulating embryonic development. The RNAseq was curry out to explore the genes influenced by lncT(LOC102165808).

Transcriptional profiling of tfap2a;tfap2c loss of function in zebrafish single whole embryos at 15 somites post fertilisation

Project description:We have genetically ablated the neural crest by simultaneously knocking out tfap2a and tfap2c in developing zebrafish embryos. We have collected 10 single embryos at the 15 somites stage from all nine possible genotypic combinations which can be found when heterozygous parent carriers of tfap2a and tfap2c are crossed. Embryos were prepped in singular, barcoded and RNA-Seq libraries were created using True-Seq stranded RNA-Seq LT kit. Libraries were paired end sequenced at 75bp on an Illumina Hi-Seq 2500.

TFAP2C signalling in human fibroblasts

Project description:Our work has shown that the transcription factor TFAP2C is upregulated in fibroblasts that generate an anisotrophic extracellular matrix. To determine what is acting downstream of TFAP2C we compared fibroblasts that had been mock transfected, or treated with a non-targeting siRNA control or siRNA against TFAP2C.

Regulation of Histone Acetylation by SUMOylation Through TFAP2C Binding to the Chromatin and Recruitment of HDAC Complex

Project description:Enhancers are fundamental to gene regulation. Post-translational modifications by the small ubiquitin-like modifiers (SUMO) modify chromatin regulation enzymes, including histone acetylases and deacetylases. However, it remains unclear whether SUMOylation regulates enhancer marks, acetylation at the 27th lysine residue of the histone H3 protein (H3K27Ac). We hypothesize that SUMOylation regulates H3K27Ac. To test this hypothesis, we performed genome-wide ChIP-seq analyses. We discovered that knockdown (KD) of the SUMO activating enzyme catalytic subunit UBA2 reduced H3K27Ac at most enhancers. Bioinformatic analysis revealed that TFAP2C-binding sites are enriched in enhancers whose H3K27Ac was reduced by UBA2 KD. ChIP-seq analysis in combination with molecular biological methods showed that TFAP2C binding to enhancers increased upon UBA2 KD or inhibition of SUMOylation by a small molecule SUMOylation inhibitor. However, this is not due to the SUMOylation of TFAP2C itself. Proteomics analysis of TFAP2C interactome on the chromatin identified histone deacetylation (HDAC) machinery. TFAP2C KD reduced HDAC binding to chromatin and increased H3K27Ac marks at enhancer regions, suggesting that TFAP2C is involved in recruiting HDAC. Taken together, our findings provide important insights into regulation of enhancer marks by SUMOylation.

Hepatic RNA sequence in male mice offspring conceived by in-vitro Fertilization and Frozen-thawed Embryo Transfer

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.

siRNA profiling of human MCF7 cells with elimination of either TFAP2C or TFAP2A reveals TFAP2C regulates multiple pathways of estrogen signaling

Project description:We were interested in determining what genes might be controlled by TFAP2C and/or TFAP2A, either directly or indirectly through regulation of ER-alpha and potentially other signaling pathways. We performed an microarray analysis in MCF7 cells with elimination of either TFAP2C or TFAP2A. The patterns of gene expression with alteration of TFAP2 activity were compared to changes in expression induced by estrogen exposure. Knock-down of TFAP2C in the presence of estrogen altered the pattern of several known ERalpha-regulated genes and a number of genes outside the estrogen-regulated pathways. Experiment Overall Design: 6 samples were analyzed. Experiment Overall Design: 1. MCF7 cells treated with TFAP2C siRNA, without the presence of estrogen. Experiment Overall Design: 2.MCF7 cells treated with TFAP2C siRNA, with the presence of estrogen. Experiment Overall Design: 3.MCF7 cells treated with TFAP2A siRNA, without the presence of estrogen. Experiment Overall Design: 4.MCF7 cells treated with TFAP2A siRNA, with the presence of estrogen. Experiment Overall Design: 5.MCF7 cells with no siRNA treatment, without the presence of estrogen. Experiment Overall Design: 6.MCF7 cells with no siRNA treatment, with the presence of estrogen.

Beta-hydroxybutyrate alters bovine preimplantation embryo development through transcriptional and epigenetic mechanisms.

Project description:Developing embryos are susceptible to fluctuations in the nutrients and metabolites concentrations within the reproductive tract, which can lead to alterations in their developmental trajectory. Ketotic dairy cows have diminished fertility, and elevated levels of the ketone body beta-hydroxybutyrate (BHB) have been associated with poor embryonic development. We used an in vitro model based on either in vitro fertilization (IVF) or parthenogenesis to investigate the effects of BHB on the preimplantation bovine embryo development, epigenome, and transcriptome. Embryo culture medium was supplemented with BHB at a similar concentration to that present in the blood of cows suffering with severe ketosis, followed by analysis of blastocysts formation rate, diameter, total number of cells, levels of H3K9 beta-hydroxybutyrylation (H3K9bhb), apoptosis, and transcriptional alterations. As a result, we observed that BHB reduced the blastocysts rates, the diameter and the total number of cells in both parthenotes and IVF embryos. Exposure to BHB for either 3 or 7 days greatly increased the H3K9bhb levels in parthenotes at the 8-cells and blastocyst stages, and affected the expression ofHDAC1,TET1,DNMT1,KDM6B,NANOGandMTHFD2genes. Additionally, culture of IVF embryos with BHB for 7 days dramatically increased H3K9bhb and reduced NANOG in blastocysts. RNA-seq analysis of IVF blastocysts revealed that BHB modulated the expression of 118 genes, which were involved with biological processes such as embryonic development, implantation, reproduction, proliferation, and metabolism. These findings provided valuable insights into the mechanisms through which BHB disrupts preimplantation embryonic development and affects the fertility in dairy cows.
