The RNA binding protein LIN28A mediates chromatin dynamics during neuronal differentiationCell death and differentiation · 2026
Summary (written by the submitters)
The transition of embryonic stem cells (ESCs) from pluripotency to lineage commitment involves complex regulatory mechanisms, including chromatin dynamics and transcriptional/post- transcriptional processes. These mechanisms often interact within intricate networks that require thorough investigation. In this study, we highlight the critical role of the mouse RNA-binding protein LIN28A in neuronal differentiation.

LIN28A mediates RNA-dependent interactions with thePolycomb repressive complex 2 (PRC2), leading to the eviction of PRC2 from chromatin andactivation of a neuronal lineage-specific transcriptional program. Proteomic analyses revealed thatthe LIN28A interactome undergoes substantial remodeling during differentiation, corresponding to changes in LIN28A localization. In undifferentiated ESCs, LIN28A primarily resides in the nucleus,interacting with PRC2 components in an RNA-dependent manner, assisting in chromatin dynamics. The absence of LIN28A results in persistent PRC2 association with chromatin, impairing theexpression of genes critical for neuronal differentiation. Chromatin immunoprecipitationsequencing further confirmed that loss of LIN28A results in preferential PRC2 occupancy at thepromoters of differentiation-associated genes. These findings reveal a novel role of LIN28A inepigenetic remodeling, crucial for proper neuronal differentiation of ESCs.

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 GSE306869_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 PRJNA1312830 and SRA study SRP614748. Searching any of these in the dataset finder brings you back here.

Study design
24 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 24 sample titles: 24 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
