Project description:We investigated which genomic regions the transcription factor Foxa2, ectopically introduced to induce hepatocyte-like cells (iHepCs) from MEFs through direct reprogramming, binds to in iHepCs.
Project description:We optimized the epigenomic profiling technology ChIL-seq for tissue. We confirmed the "ChIL for tissue" has sufficient sensitivity, specificity and reproducibility, in identification of enhancers, transcription factors, transcriptional activation genes in a single-thin-section of tissues.
Project description:Forkhead box A2 (FOXA2) is a critical regulator of endometrial gland development in mice. In the adult mouse uterus, FOXA2 is expressed solely in the GE cells of the endometrium. Conditional deletion of Foxa2 after birth in the uterus, using the progesterone receptor Cre mouse (PgrCre), impeded gland development, thereby rendering the adult mouse infertile due to defects in blastocyst implantation stemming from a lack of endometrial glands and their secretions. As a first step to begin understanding the FOXA2 function in the endometrial glands of the uterus, genome-wide investigation of in vivo FOXA2 and RNA polymerase II (POL2) binding target regions in the neonatal and adult uterus was determined by chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq).

In order to determine the transcriptional regulatory networks mediating FOXA2 regulation of endometrial gland development and function, chromatin immunoprecipitation and massively parallel sequencing (ChIP-Seq) was used to create a genome-wide profile of in vivo FOXA2-binding sites in the developing (PD 12) and adult (DOPP 2.5 and 3.5) mouse uterus.
Project description:In order to identify FOXA2 binding sites in a genome-wide fashion, we infected H441 cells with lentivirus that carries rat Foxa2 and performed chromatin immunoprecipitation-sequencing (ChIP-seq) for FOXA2.
Project description:We investigated which genomic regions the transcription factor Hnf4a, ectopically introduced to induce hepatocyte-like cells (iHepCs) from MEFs through direct reprogramming, binds to in iHepCs.
