Project description:Gene expression changes between livers of treated WT and dKO (Foxa1 and Foxa2 KO) male and female mice and untreated female (WT and dKO) mice were measured to identify pathways related to Foxa1/2 regulation of pathways involved in liver cancer. The experiment uses 4 replicates each for 6 conditions

Project description:FOXA1 and FOXA2 are essentail transcription factors for proper gut development. In adults, they have a role in the differentiation of intestinal secretory cell lineages and were also reporeted to directly activate Muc2 transcription. Here we show that deletion of Foxa1 and Foxa2 in mouse intestinal epithelium leads to a downregulation of glycosylation genes in the colon and to a massive change of the colonic surface glycans. In turn, the microbiome composition shifts dramatically and spontaneous inflammatory bowel disease ensued. We conclude that vertebrates shape a favorable microbiome by establishing a glycocalyx to nurture specific bacterial taxa through control of the epithelial glycosylation program by the FoxA transcription factors.
Project description:SRSF2 flanked with flox was specifically depleted in the livers by Alb-Cre(HKO),and took the intact ones as contorl(WT).Near 70% of the HKO livers spontaneously developed malignant tumors(took the tumor areas as tumor while the tumor-adjacent as nontumor).Then total RNAs of 2-month WT/HKO and 12-month WT/nontumor/tumor were isolated and performed the next generation sequencing. We profiled the gene expression regulated by Cre-loxp-mediated knockout system.
Project description:To characterize the genome-wide regulatory cistrome of Foxa1 and Foxa2, we performed both Foxa1 and Foxa2 chromatin immunoprecipitation followed by sequencing (ChIP-seq) on freshly dissociated prostate tumor cells at the early stage (2 weeks post tamoxifen administration) and the late stage (6 months post tamoxifen administration) of NEPC progression, respectively.
Project description:FOXA1 and FOXA2 are essentail transcription factors for proper gut development. In adults, they play a role in the differentiation of intestinal secretory cells and were also reporeted to directly activate Muc2 transcription. Here we show that FOXA1 and FOXA2 bind near goblet cell genes, and are specifically enriched near glycosylation genes. Deletion of these transcription factors in mouse intestine leads to a downregulation of glycosylation genes in the colon and to a massive change of the colonic surface glycans. I turn, the microbiome composition shifts dramatically and spontaneous inflammatory bowel disease ensued. We conclude that vertebrates shape a favorable microbiome by establishing a glycocalyx to nurture specific bacterial taxa through control of the epithelial glycosylation program by the FoxA transcription factors.
Project description:Purpose: The goal of this study is to compare transcriptome profilings of liver from Mettl3 flox/flox and hepatocyte-specific Mettl3 knockout (HKO) mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from livers of Mettl3 flox/flox and HKO mice at 8 weeks old. mRNA profiles were generated by deep sequencing using an Illumina HiSeq X Ten platform. Paired-end clean reads were aligned to the mouse reference genome(Ensemble_GRCm38.90) with Hisat2 (version 2.0.4), and the aligned reads were used to quantify mRNA expression by using HTSeq (version 0.9.1). Conclusion: The hepatic mRNA profiles in Mettl3 flox/flox and HKO mice were characterized.
Project description:To investigate the potential mechanism by which RECS1 regulate metabolic disorder, we treated control mice and RECS1 HKO mice with HFD for 8 weeks, and performed microarray to identify the expression pattern and the potential important molecules regulated by RECS1. We used microarrays to detect the global gene expression in the livers of control mice and RECS1 HKO mice after treatment with HFD for 8 weeks and identified distinct classes of altered genes in the livers of mice upon HFD compared .
