Project description:Histone deacetylase 1 and 2 (HDAC1/2) regulate chromatin structure as the catalytic core of the Sin3A, NuRD and CoREST co-repressor complexes. To better understand the key pathways regulated by HDAC1/2 in the adaptive immune system and inform their exploitation as drug targets, we have generated mice with a T cell specific deletion and performed comparative genomic hybridisation using genomic DNA from HDAC1-/-; HDAC2+/- diseased thymocytes and sample-matched, wild-type tail. A data set from a related transcription-profiling study comparing HDAC1-/-; HDAC2+/- mouse thymus tissue against thymus tissues from wild-type counterparts has also been deposited at ArrayExpress under accession E-MTAB-1432: http://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1432

Project description:Transcriptional profiling of mouse embryonic kidneys (E13.5) comparing UB HDAC1,2-/- kidneys with wild type kidneys. Studies in our lab showed that histone deacetylase 1 (HDAC1) and 2 (HDAC2) perform redundant, yet essential functions in the developing mouse ureteric bud (UB) tissue. Double deletion of HDAC1 and HDAC2 in the UB results in impaired UB branching morphogenesis, followed by severe kidney dysgenesis. The goal of the microarray analysis was to identify the genetic pathways controlled by HDAC1 and 2 in the UB.

Project description:CD44 wild-type and knockout C57 BL/6 mice were immunized by subcutaneous injection of MOG35-55 peptide. CD4 T cells were isolated from spleens of the mice on day 15 of the MOG35-55 peptide immunization. Peripheral blood lymphocytes (PBLs) were prepared from multiple sclerosis patients and normal individuals. Total RNA was extracted and subjected to microRNA high-throughput array with Affymetrix platform.

Project description:Histone deacetylase 1 and 2 (HDAC1/2) are the core catalytic components of co-repressor complexes which modulate gene expression. In most cell types, deletion of both Hdac1 and Hdac2 is required to generate a discernible phenotype, suggesting their activity is largely redundant. We have therefore generated an embryonic stem cell (ES) line in which Hdac1 and Hdac2 can be inactivated simultaneously using a Tamoxifen inducible CreER fusion. Loss of HDAC1/2 results in a 60% reduction in total HDAC activity and a loss of cell viability. Cell death is cell cycle dependent, since differentiated, non-proliferating cells, retain their viability. Furthermore, we observe increased mitotic defects, lagging chromosomes and micronuclei, suggesting HDAC1/2 maintain chromosomal stability. Consistent with a critical role in the regulation of gene expression, microarray analysis of Hdac1/2 deleted cells reveals 1,708 differentially expressed genes. Significantly for the maintenance of stem cell self-renewal, we detected a reduction in the expression of the pluripotent transcription factors, Oct4, Nanog and Rex1. HDAC1/2 activity is regulated through binding of inositol tetraphosphate molecule [Ins(1,4,5,6)P4] (IP4) sandwiched between the HDAC and its cognate co-repressor. This raises the important question of whether the IP4 actually regulates the activity of the complex in cells. By rescuing the viability of DKO cells, we demonstrate for the first time that mutations which abolish IP4 binding reduce the activity of HDAC1/2 in vivo. Our data indicate that HDAC1/2 have a generic, but essential role in cellular proliferation and regulate stem cell self-renewal by maintaining expression of key pluripotent transcription factors. Comparative gene expression profiles of wild type (Day 0) were compared to Hdac1lox/lox, Hdac2lox/lox; CreER ES cells on days 1, 2 and 3 following for OHT treatment using the Illumina mouseWG-6 v2 expression BeadChip platform. wild type (Day 0) were compared to Hdac1lox/lox, Hdac2lox/lox; CreER ES cells on days 1, 2 and 3 following for OHT treatment. Four time points were analyzed in triplicate.
