(Submitter supplied) Understanding factors that drive development and function of the sympathetic neuron is crucial to development of potential therapies for neuroblastoma. Here, we identify a key cell autonomous role for the LIM homeodomain transcription factor ISL1 for survival, proliferation and differentiation of sympathetic neurons throughout development. Analysis of several Isl1 mutant mouse lines, including one in which Isl1 was specifically ablated in sympathetic neuron (Wnt1-cre;Isl1 f/f) revealed an early requirement for Isl1 within sympathetic neurons for proliferation and surrvial. more...

(Submitter supplied) Understanding factors that drive development of the sympathetic neuron is crucial to development of potential therapies for neuroblastoma. Here, we identify a key cell autonomous role for the LIM homeodomain transcription factor ISL1 for survival, proliferation and differentiation of sympathetic neurons throughout development. Chromatin immunoprecipitation assays performed utilizing antibody to ISL1 in chromatin extracts from sympathetic neurons demonstrated that ISL1 directly binds genomic regions within several genes critical for sympathetic neuron development and function, including subunits of the Insm1, Lmo1,Tlx3 and Prox1. more...

(Submitter supplied) Acquisition of the lower jaw (mandible) was evolutionarily important for jawed vertebrates. In humans, syndromic craniofacial malformations often accompany jaw anomalies. Hand2 is involved in coordinating the developmental network of mandibles and the oral apparatus through Hand2-downstream genes and is therefore a major determinant of jaw identity. We used microarrays to detail the global programme of gene expression involved in mandible specification and identified distinct classes of up-regulated genes during this process.

(Submitter supplied) Neurons derived from human pluripotent stem cells (hPSCs) are a remarkable tool for modeling human neural development and diseases. However, it remains largely unknown whether the hPSC-derived neurons can be functionally coupled with their target tissues in vitro, which is essential for understanding inter-cellular physiology and further translational studies. Here, we demonstrate that hPSC-derived sympathetic neurons can be obtained from hPSCs and that the resulting neurons form physical and functional connections with cardiac muscle cells. more...

(Submitter supplied) Neuroblastoma is a tumor of the peripheral sympathetic nervous system, derived from multipotent neural crest cells (NCCs). To define Core Regulatory Circuitries (CRCs) controlling the gene expression program of neuroblastoma, we established and analyzed the neuroblastoma super-enhancer landscape. We discovered three types of identity in neuroblastoma cell lines: a sympathetic noradrenergic identity defined by a CRC module including the PHOX2B, HAND2 and GATA3 transcription factors (TFs); an NCC-like identity, driven by a CRC module containing AP-1 family TFs; a mixed type further deconvoluted at the single cell level. more...

(Submitter supplied) Gata4, Mef2c, Hand2, and Tbx5 (GHMT) can reprogram transduced fibroblasts into induced pacemaker-like myocytes (iPMs), but the underlying mechanisms remain obscure. Here we explored the role of Hand2 in iPM formation by using a combination of transcriptome, genome, and biochemical assays. We found many shared transcriptional signatures between iPMs and endogenous sinoatrial node (SAN), yet key regulatory networks remain missing. more...
