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.

Role of Hopx in myogenesis and commitment [HopxKO+Wnt]

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 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.
