C/EBP-β/LAP Controls Down-regulation of Albumin Gene Transcription during Liver Regeneration

Down Regulation of DHFR Promoter Activity by PML Transcription Repressor

alpha-Fetoprotein gene sequences mediating Afr2 regulation during liver regeneration.

alpha-fetoprotein (AFP) gene expression occurs in the yolk sac, in the fetal liver and gut, and in the adult liver during regeneration and tumorigenesis. Two unlinked genes determine the level of AFP gene expression in adult mice: Afr1 regulates the basal level of expression in the normal adult liver, and Afr2 regulates the increase in expression during liver regeneration. It has been shown tha...

Regulation of signal transduction during liver regeneration

The liver has a tremendous capacity to regenerate. For example, after extensive hepatic resection, remaining hepatocytes proliferate to restore the mass of the organ within days to weeks. This proliferative response is fascinating because hepatocytes rarely replicate in the healthy adult liver. Instead, these cells perform highly specialized functions and exemplify mature, terminally differenti...

Down-Regulation of MiR-127 Facilitates Hepatocyte Proliferation during Rat Liver Regeneration

Liver regeneration (LR) after partial hepatectomy (PH) involves the proliferation and apoptosis of hepatocytes, and microRNAs have been shown to post-transcriptionally regulate genes involved in the regulation of these processes. To explore the role of miR-127 during LR, the expression patterns of miR-127 and its related proteins were investigated. MiR-127 was introduced into a rat liver cell l...

Down-Regulation of microRNA-26a Promotes Mouse Hepatocyte Proliferation during Liver Regeneration

BACKGROUND Inadequate liver regeneration (LR) is still an unsolved problem in major liver resection and small-for-size syndrome post-living donor liver transplantation. A number of microRNAs have been shown to play important roles in cell proliferation. Herein, we investigated the role of miR-26a as a pivotal regulator of hepatocyte proliferation in LR. METHODOLOGY/PRINCIPAL FINDINGS Adult ma...
