BCL11A-deficient human erythropoiesis is impaired in vitro and after xenotransplantation into miceBlood advances · 2025
Summary (written by the submitters)
Genetic depletion of the transcriptional repressor BCL11A in red blood cell precursors alleviates b-hemoglobinopathies by inducing the fetal g-globin genes. However, several additional erythroid genes are regulated by BCL11A and the effects of its deficiency on erythropoiesis are insufficiently described. We discovered that Cas9 disruption of the BCL11A intron 2 erythroid enhancer in CD34+ hematopoietic stem and progenitor cells (HSPCs) according to a clinically approved strategy caused impaired expansion and increased apoptosis of erythroid precursors in vitro and in vivo.

Mutant colony-forming unit erythroid (CFU-e), proerythroblasts, and basophilic erythroblasts exhibited dysregulation of 94 genes (> 2-fold change, FDR < 0.05). 25 of which are likely direct targets of BCL11A. Differentially expressed genes were associated with numerous biological pathways that impact cell expansion and survival. Our findings show that BCL11A regulates additional aspects of erythropoiesis beyond g-globin gene repression.

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 GSE283793_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 PRJNA1195593 and SRA study SRP550079. Searching any of these in the dataset finder brings you back here.
