PAR3-mediated coordination of hepatocyte proliferation, maturation, and architecture in liver development and regenerationNature communications · 2026
Summary (written by the submitters)
The coordination of cell proliferation, polarization, and maturation with architectural assembly is crucial for liver development and regeneration, yet the mechanisms underlying this coordination remain unclear. Using both murine and human models, we demonstrate that hepatic cell polarity and bile canaliculi (BC) formation initiate at sites of cell division during the hepatoblast stage, while BC elongation occurs following hepatocyte differentiation.

This elongation requires suppression of ERK/MAPK activity mediated by PAR3 and YAP. PAR3 interacts with a complex network of proteins, including IQGAP1, at tight junctions, thereby sequestering IQGAP1 from basolateral membranes where it typically promotes growth factor-induced ERK/MAPK activation. This PAR3-ERK/MAPK pathway further regulates actin organization and oriented cell division, both essential for BC elongation and hepatocyte maturation throughout liver development and regeneration. These findings provide new insights into a fundamental mechanism integrating cell proliferation, maturation, and architectural assembly, with implications for regenerative medicine and liver disease therapies.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE281035_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1181868 and SRA study SRP543079. Searching any of these in the dataset finder brings you back here.
