  • 基因功能參考文獻：
    1. Data suggest that hepatocytes can be reprogrammed into insulin-producing cells in vivo by transfection of neurogenin-3, Pdx1, and MafA genes using non-viral hydrodynamics injection; this procedure was used in treatment of streptozotocin diabetes; fasting blood glucose was reduced to normal. (Pdx1 = pancreatic and duodenal homeobox 1; MafA = v-maf musculoaponeurotic fibrosarcoma oncogene family, protein A) PMID: 28100871

    3. is necessary for the maintenance of normal insulin levels even in embryos. PMID: 25912440

    32. Our results provide evidence that genetic interactions involving Ret and MafA progressively promote the differentiation and diversification of LTMs. PMID: 20064392
