Summary (written by the submitters)
Chromatin organization is a pivotal factor in stem cell pluripotency and differentiation. However, despite considerable study, the role of enhancer looping protein LDB1 in these processes has not been explored. Here, we generated Ldb1(-/-) embryonic stem cells (ESC) using CRISPR/Cas9 editing to understand the significance of LDB1 during development.

Ldb1(-/-) ESC exhibited a reduction in key stem cell factors SOX2 and KLF4. Embryoid bodies (EB) derived from Ldb1(-/-) ESC displayed reduced expression of lineage-specific markers and impaired ability to undergo terminal differentiation to erythroblasts. Transcriptome analysis revealed differential gene expression between WT and Ldb1(-/-) ESC and EB but altered gene expression was most pronounced after differentiation to erythroblasts. The Lin28-mediated stem cell self-renewal pathway was dysregulated in Ldb1(-/-) cells. Our data reveal that LDB1 occupies super enhancers of pluripotency genes in ESC together with pluripotency factors. LDB1 loss resulted in a global decrease in chromatin accessibility in ESC and EB. Conditional LDB1-deficient mice showed reduced hematopoietic stem cell markers on bone marrow cells, and dysregulation of the Lin28/Let-7/Hmga2 pathway. We conclude LDB1 function is critical for ESC and EB development and becomes progressively more important during differentiation to erythroblasts.

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 GSE282374_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 PRJNA1188464 and SRA study SRP546363. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 12 sample titles; they account for 12 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.
