Project description:Analysis of heart ventricles from Hopx, Hdac2, and both Hopx-Hdac2 deficient embryos at embryonic day E16.5. Results provide insight into the role of Hopx and Hdac2 in cardiac development. We used microarrays to detail the global programme of gene expression underlying cardiac development by Hopx and Hdac2 and identified distinct classes of up-regulated and down-regulated genes during this process. Mouse embryonic ventricles were selected at E16.5 for RNA extraction and hybridization on Affymetrix microarrays. We obtained three independent embryonic ventricles for WT, Hopx-null, Hdac2-null, and Hopx-Hdac2 double null genotypes.

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:Progenitor cells require coordinated expression of lineage-specific genes to regulate differentiation into daughter cell types. Hopx labels cardiac progenitors that are commited to the cardiac myocyte lineage. Hopx-deficiency leads to thin myocardium in approximately mid-gestation lethality in approximately 50% of embryos (secondary to thin myocardium and presumed cardiac rupture). Hopx-/- EBs display impaired myogenesis during cardiac differentiation. ChIP-seq and RNA expression analysis suggests that Hopx down regulates Wnt signaling by directly occupying and repressing wnt ligand genes. Analysis of embryoid bodies on day 8 of cardiac differentiation. RNA was made of from 1. Hopx +/- embryoid bodies, 2. Hopx -/- embryoid bodies, Embryonic stem cell lines were derived from littermate mouse blastocysts. Results provide insight into gene programs regulated by Hopx in cardiac development.

Analysis of embryoid bodies on day 8 of cardiac differentiation. RNA was made of from Hopx +/- embryoid bodies or Hopx -/- embryoid bodies treated with 12.5 uM XAV939. Heterozygous embryoid bodies included 0 uM XAV939, a well-characterized, known Wnt inhibitor. Embryonic stem cell lines were derived from littermate mouse blastocysts. Results provide insight into gene programs regulated by Hopx in cardiac development.

Project description:The histone deacetylase HDAC2, which negatively regulates neuronal plasticity and synaptic gene expression, is upregulated both in Alzheimer’s disease (AD) patients and mouse models (Graff et al., 2012). Therapeutics targeting HDAC2 are speculated to be a promising avenue for ameliorating AD related cognitive impairment. However, attempts to generate HDAC2-specific inhibitors have not been successful. Here, we take a novel approach utilizing integrative genomics to identify proteins that mediate HDAC2 recruitment to synaptic plasticity genes. Functional screening revealed that knockdown of the transcription factor Sp3 phenocopied HDAC2 knockdown, and that Sp3 facilitated the recruitment of HDAC2 to synaptic genes. Importantly, like HDAC2, Sp3 expression was elevated in AD patients and mouse models, where Sp3 knockdown ameliorated synaptic dysfunction. Furthermore, exogenous expression of an HDAC2 fragment containing the Sp3 binding domain fully restored synaptic plasticity and memory in a mouse model with severe neurodegeneration. Our findings indicate that targeting the HDAC2-Sp3 complex could enhance synaptic and cognitive function, without affecting HDAC2 function in other processes.
