Expression data from mouse heart deficient of HDAC3

ABSTRACT: Gene expression changes in the heart of MCH3-KO mouse (HDAC3 f/f, Muscle Creatine Kinase-Cre) versus control WT mouse (HDAC3 f/f). Histone deacetylases (HDACs) play important roles in cardiac development and function. We show here that mice deficient of HDAC3 in heart and skeletabl muscle are relatively normal on normal chow, but develop hypertrophic cardiomyopathy and heart failure that leads to death on high-fat diet. This microarray experiment is to explore the underlying molecular mechanism.

This microarray experiment is to explore the underlying molecular mechanism. Hearts from 6-weeks old WT and MCH3-KO C57BL/6 mice (n=4 in each group, male) on normal chow were subjected to RNA extraction and Affymetrix Mouse Gene 1.0ST analysis.

Discovery of a Highly Potent and Selective HDAC3 and HDAC8 PROTAC Dual Degrader

Project description:HDAC3 and HDAC8 are members of class I deacetylases involved in several biological mechanisms and represent a highly sought-after therapeutic target for drug development. It is historically challenging to develop selective deacetylase inhibitors due to their conserved catalytic domains. HDAC3 also has deacetylase-independent activity, which cannot be blocked by conventional enzymatic inhibitors. Recent advances in proteolysis-targeting chimeras (PROTACs) provides an opportunity to eliminate the whole protein selectively, abolishing both enzymatic and scaffolding functions. Here, we report a novel HDAC3/8 dual degrader YX968 that induces highly potent, rapid and selective degradation of both HDAC3 and HDAC8 without trigging pan-HDAC inhibitory effects. Unbiased quantitative proteomics experiments further confirmed its high selectivity. This dual-specific degrader specifically ablates cellular pathways attributed to HDAC3 and HDAC8 and exhibits high potency in killing cancer cells. YX968 represents a new probe for dissecting the complex biological functions of HDAC3 and HDAC8.

HDAC3 ensures stepwise epidermal stratification via NCoR/SMRT-reliant mechanisms independent of its histone deacetylase activity (HDAC3 NCoRSMRT microarray)

Project description:Chromatin modifiers play critical roles in epidermal development, but the functions of histone deacetylases in this context are poorly understood. We find that the Class I HDAC, HDAC3, is expressed broadly in embryonic epidermis, and is required for its orderly stepwise stratification. Stability of HDAC3 protein in vivo is reliant on NCoR and SMRT, which function redundantly in epidermal development. However, point mutations in the NCoR and SMRT Deacetylase Activating Domains, which are required for HDAC3’s enzymatic function, permit normal stratification, indicating that HDAC3’s roles in this context are independent of its histone deacetylase activity. HDAC3 functions both in conjunction with, and independent of, KLF4 to repress premature expression of different sets of terminal differentiation genes and suppresses expression of inflammatory cytokines through a RelA-dependent mechanism. These data identify HDAC3 as a hub coordinating multiple aspects of epidermal barrier acquisition. We used microarrays to determine transcriptional changes in Hdac3 deleted epidermis compared to control and Ncor1/Ncor2 deleted epidermis compared to control.

changes in cardiac transcription profiles brought about by heart failure

Project description:To establish changes in cardiac transcription profiles brought about by heart failure we collected myocardial samples from patients undergoing cardiac transplantation whose failure arises from different etiologies (e.g. idiopathic dilated cardiomyopathy, ischemic cardiomyopathy, alcoholic cardiomyopathy, valvular cardiomyopathy, and hypertrophic cardiomyopathy) and from "normal" organ donors whose hearts cannot be used for transplants. The transcriptional profile of the mRNA in these samples will be measured with gene array technology. Changes in transcriptional profiles can be correlated with the physiologic profile of heart-failure hearts acquired at the time of transplantation. Keywords: other

Expression data from human heart

Project description:Global gene expression is altered in heart failure. This syndrome can be caused by cardiovascular diseases, including dilated cardiomyopathy (DCM), ischemic cardiomyopathy (ICM), hypertrophic cardiomyopathy, viral or toxic myocarditis, hypertension, and valvular diseases. We used microarrays to evaluate the impact of heart failure on human nucleocytoplasmic transport-related genes examining simultaneoulsly both dilated and ischemic human cardiomyopathies compared to normal hearts.

miRNA expression profiles in the serum of cats with hypertrophic cardiomyopathy compared to healthy cats

Project description:MicroRNAs negatively regulate gene expression and may serve as biomarkers for human cardiomyopathy. In the domestic cat, hypertrophic cardiomyopathy (HCM) represents the most common primary cardiomyopathy. In humans, the etiology of HCM is linked to mutations in genes of contractile muscle proteins, while in cats a clear proof for causal mutations is missing. The etiology of feline HCM is uncertain. Diagnosis is made by heart ultrasound examination and measuring the serum level of N-terminal pro B-type natriuretic peptide. The purpose of this study was to investigate whether microRNA profiles in the serum of cats with HCM are different from the profiles of healthy cats and whether specific miRNAs can be detected to serve as potential biomarkers for feline HCM or may help in understanding the etiology of this disease Blood was drawn from two groups of cats: 12 healthy cats and 11 cats suffering from hypertrophic cardiomyopathy. After clotting, samples were centrifuged and total mRNA was extracted from serum. These 23 serum samples were analyzed and the groups were compared
