Y-box protein-1 (YB-1) is a highly conserved transcription factor that is
involved in multiple biological processes via transcriptional regulation of
several genes, including p53, cyclin D1, and EGFR. YB-1 has been reported to be
overexpressed in injured livers. This study aims to explore the functions of YB-1
in hepatic progenitor cells (HPCs). Herein, chromatin immunoprecipitation
sequencing (ChIP-sequencing) and RNA-sequencing assays identified that YB-1
participated in the biological adhesion process and ECM-receptor interactions in
HPCs. Further study demonstrated that YB-1 modulated the expression of
extracellular matrix components in HPCs. ChIP-sequencing assays established that
PDGFR-? was a target gene of YB-1, and luciferase reporter assays confirmed that
YB-1 negatively regulated PDGFR-? promoter activity in HPCs. In addition, PDGFR-?
can regulate the expression of collagen I through ERK/p90RSK signalling, and
disruption of the signalling pathway with a PDGFR-? inhibitor or ERK1/2 inhibitor
abolished the regulatory effect of PDGFR-? on collagen I expression in HPCs.
Conclusively, YB-1 can modulate the expression of collagen I in HPCs via direct
binding to the PDGFR-? promoter, negatively regulating its expression. In
addition, the ERK/p90RSK axis serves as the downstream signalling pathway of
PDGFR-?.
