Research Abstract |
Growth and differentiated functions of mature hepatocytes are reciprocally regulated by cell density. (1) We found that a furin-like protease activity is involved in HGF-mediated LAR activation under high-cell density conditions. (2) Using TDO promoter-EGFP transgenic mice, we found that a conserved homologous region exists among the species. Furthermore, C/ EBP-αcan bind its site and activate promoter activity. (3) Proline is an essential amino acid for hepatocyte growth. Proline increased accumulation of cyclin D and E proteins via newly synthesized collagen.
