Project description:Purpose: The goal of this study is to compare the cardiac transcriptome profiling (RNA-seq) of WT and CHD4-M195I hearts at E18.5 to conclude genes affected by this CHD4 mutation. Methods: mRNA profiles of E18.5 WT and CHD4-M195I mouse hearts were generated by deep sequencing, n=4 for each genotype, using Illumina HiSeq2500. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: RNA-sequencing (RNA-seq) analyses on E18.5 WT and CHD4-M195I hearts and identified 323 genes that were differentially expressed [adjusted P value <0.05, |log2(Fold Change)| > 0.5], 113 upregulated and 210 downregulated in CHD4-M195I hearts.
Project description:To evaluate the DNA methylation in LSK cells from the bone marrow of wildtype or Tet2/3 DKO mice. In order to address the impact of the loss of Tet2/3 proteins in DNA methylation in LSK cells, we compared by WGBS the methylome of wild and, Tet2/3 DKO LSK cells in bone marrow.
Project description:Microarray experiment to identify changes in gene expression in 18.5 day post coitum Tex19.1-/- mouse placenta. Tex19.1 is expressed in trophectoderm-derived cells in the placenta. Tex19.1-/- placentas are small and have defects in junctional zone and labyrinth layers of the placenta, Tex19.1-/- embryos exhibit intra-uterine growth retardation. Data provides insight into the changes in gene expression and cell composition in Tex19.1-/- placentas. Six E18.5 Tex19.1-/- placentas (KO: four XX, two XY), four E18.5 Tex19.1+/- littermate control placentas (HET: four XX), and two E18.5 Tex19.1+/+ littermate control placentas (WT: two XY) are included in the analysis.
Project description:In this study, we show that by simple modulation of extrinsic signaling pathways, a new class of pluripotent stem cells, referred to as region selective epiblast stem cells (rsEpiSCs), could be efficiently derived from different stages of the early embryo. rsEpiSCs share features of primed pluripotency yet are distinct from EpiSCs in their molecular characteristics and ability to colonize post-implantation embryos. We performed whole-genome bisulfite sequencing (WGBS) experiments to compare the DNA methylation landscapes of conventional EpiSCs and rsEpiSCs. Compare the DNA methylation profiles in 2 pluripotent stem cell types (LP-EpiSCs and conventional EpiSCs) in mouse. Two replicates are examined for each cell type.
Project description:Rosa26rtTA;tetOsFgfr2b (C75Bl6) induced from E16.5 until E18.5, lungs were harvest at E18.5, AECI and AECII were sorted using FACS. Mice were kept on water and food ad libitum.
