PG - 706-720 LID - S2213-6711(20)30282-4 [pii] LID - 10.1016/j.stemcr.2020.07.005 [doi] AB - Liver progenitor cells (LPCs) have a remarkable contribution to the hepatocytes and ductal cells when normal hepatocyte proliferation is severely impaired. As a biomarker for LPCs, Sry-box 9 (Sox9) plays critical roles in liver homeostasis and repair in response to injury. However, the regulation mechanism of Sox9 in liver physiological and pathological state remains unknown. In this study, we found that miR-126 positively regulated the expression of Sox9, the proliferation and differentiation of SOX9(+) LPCs by suppressing the translation of homeobox b6 (Hoxb6). As a transcription factor, HOXB6 directly binds to the promoter of Sox9 to inhibit Sox9 expression, resulting in the destruction of the properties of SOX9(+) LPCs in CCl(4)-induced liver injury. These findings revealed the role of miR-126 in regulating SOX9(+) LPCs fate by targeting Hoxb6 in liver injury repair. Our findings suggest the potential role of miR-126 as a nucleic acid therapy drug target for liver failure. CI - Copyright (c) 2020 The Authors. Published by Elsevier Inc. All rights reserved.
