Summary (written by the submitters)
Differential chromatin accessibility accompanies and mediates transcriptional control of diverse cell fates and their differentiation during embryogenesis. While the critical role of NKX2-1 and its transcritional targets in lung morphogenesis and pulmonary epithelial cell differentiation is increasingly known, mechanisms by which chromatin accessibility alters the epigenetic landscape to regulate NKX2-1 activites required for alveolar epithelial cell differentiation and function are not well understood.
Read the full summary ↓
Herein, we demonstrate that the paird domain zinc finger transcriptional regulators PRDM3 and PRDM16 regulate chromatin accessibility required for NKX2-1 mediated AT1 and AT2 cell differentiation decisions during lung morphogenesis and for control of the induction of AT@ cell gene expression controlling alveolar function and ventilation at birth. PRDM3 and 16 were required for activation of AT2 cell-associated gene expression, enhancing chromatin accessibility at NKX2-1 transcriptional targets. NKX2-1, PRDM3, and PRDM16 bound together at cis-active DNA elements in AT2 and AT1 cell selective transcriptional target genes, including those critical for perinatal AT2 cell differentitaion, surfactant homeostasis, and innate host defense. Deletion of PRDM3/16 inhibited NKX2-1-dependent gene regulatory networks controlling surfactant lipid and protein production, resulting in respiratory failure at birth. NKX2-1-dependent regulation of alveolar epithelial cell differentiation is mediated by PRDM3/16.

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 GSE250359_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 PRJNA1053412 and SRA study SRP478323. Searching any of these in the dataset finder brings you back here.

Study design
6 × ATAC lungs, Control, vs 5 × ATAC lungs, Prdm3/16KO,

Supports a between-group comparison across 11 samples.

How we read this: 2 replicated groups read from 11 sample titles; they account for 11 of them. 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.
