Project description:Cardiac hypertrophy and failure are accompanied by a reprogramming of gene expression that involves transcription factors and chromatin remodeling enzymes. Little is known about the role of histone methylation and demethylation in this process. To understand the role of JMJD2A, a trimethyl demethylase for histone 3 lysine 9 and 36, in cardiac hypertrophy, we generated heart specific JMJD2A deletion (JMJD2A hKO) and overexpression (JMJD2A-Tg) mouse lines. JMJD2A hKO and JMJD2A-Tg mice are viable and have no overt baseline phenotype. However, they have altered responses to cardiac stresses. While inactivation of JMJD2A in hKO mice resulted in an attenuated hypertrophic response to transverse aortic constriction (TAC)-induced pressure overload compared to that of control littermates, JMJD2A-Tg mice have exacerbated cardiac hypertrophy after TAC.

Project description:Base on the privious studie from our lab, we found the histone demethylases, Jmjd2a and Jmjd2c are upregulated in stimulated primary B cells, depletion of Jmjd2a and Jmjd2c in stimulated B cells resulted in failed activation of B cells. Owimg to the essential functions of Jmjd2a and Jmjd2c, We here applied loss of function approach, such as siRNA, to study the how Jmjd2a and Jmjd2c regulate plasma cell differentiation.

Project description:Here we reported the Jmjd2a and Jmjd2c are co-targeted at the essential genes of mouse activating B220+ B cells. B cell activation programs transcription networks that subsequently induce plasma cell differentiation, but how histone demethylases participating in this process remains elusive. We found that histone demethylases Jmjd2a and Jmjd2c are expressed in Tfh-mediated signals stimulated mouse spelenic B220+ B cells. we then perform ChIP-seq by using anti-Jmjd2a and anti-Jmjd2c antibodies to identified the genes regulated by Jmjd2a and Jmjd2c and required for correct activation.

Project description:Purpose: The goal of this study is to identify the differential cardiac transcriptome profiling between WT and Smyd1 null (Smyd1-KO) hearts at E9.5 using RNA-seq. Methods: mRNA profiles of E9.5 WT and Smyd1-KO mouse hearts were generated by deep sequencing, n=3 for each genotype, using Illumina HiSeq2500. The sequence reads were aligned to the mm10 reference genome using STAR via the bcbio-nextgen RNA-sequencing pipeline. Differential gene expression was determined by DEseq2. Results: 1756 genes were differentially expressed between WT and Smyd1-KO hearts [adjusted P value <0.05, |log2(Fold Change)| > 0.5], with 1130 upregulated and 626 downregulated in E9.5 Smyd1-KO hearts.

Project description:CCBE1 is a secreted extracellular matrix protein expressed by epicardial cells but its role during epicardial development was still unknown.Using a Ccbe1 knockout (KO) mouse model, we observed that loss of CCBE1 leads to congenital heart defects including thinner and hyper-trabeculated ventricular myocardium. In addition, Ccbe1 mutant hearts displayed reduced proliferation of cardiomyocyte and epicardial cells. RNA-seq data of CCBE1 KO and WT murine hearts indicated deregulation of genes associated with development and morphogenesis including the epithelial-to-mesenchymal transition.

Project description:Purpose: The goal of this study is to identify the differential cardiac chromatin accessibility between WT and Smyd1 null (Smyd1-KO) hearts at E9.5 using ATAC-seq. Methods: Four hearts at E9.5 were pooled per genotype per replicate, and were then dissociated into single cells. 40,000 viable cells were taken for were lysed to isolate nuclei, which were treated with Tn5 transposase (Nextera DNA Sample Prep Kit, Illumina) to isolate DNA. Fragmented DNA was then amplified using bar-coded PCR primers and libraries were seuqenced. Results: 25851 differential peaks (2-fold change) were identified between E9.5 WT and Smyd1-KO hearts.
