basic FUNCTION
  • regulating the cardiac development and in the developing of Schwann cells of the peripheral nervous system
  • playing a key role in the differentiation of male gonads
  • combinatorial expression of the paracrine factor DHH and nuclear transcription factor SF1 is required for Leydig cell development
  • is essential for testis development and Schwann cell function
  • DHH promotes peripheral nerve survival in the ischemic muscle and, by doing so, maintains the pool of nerve-derived proangiogenic factors
  • controls the formation of the nerve perineurium during development and is a key component of Schwann cells that ensures peripheral nerve survival
  • pivotal role for DHH in maintaining myelination
  • critical role of DHH in maintaining blood nerve barrier integrity, demonstrating time that endothelial dysfunction is sufficient to induce neuropathy
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS cardiovascular
    PATHWAY
    metabolism
    signaling
  • DHH signaling plays an essential role in the normal development of the testis and in the process of spermatogenesis
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • GLI family in mediating the carcinogenic effect of hedgehog pathway activation
  • SMO (essential component of HH signaling)
  • Sertoli cells coordinate DHH-dependent spermatogenesis events via PTCH1 and SMO prior to the first meiotic division and in postmeiotic (haploid) cells, particularly during the first half of spermiogenesis
  • SOX10 activates DHH expression in Schwann cells via an enhancer that is located in intron 1 of the DHH gene
  • cell & other

  • mice lacking both Dhh and Ihh had loss of normal ovarian function
  • in Dhh-deficient mice, Dhh negatively regulates multiple stages of erythrocyte differentiation
