What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)

12 samples: 3 × knockout, differentiation d2, vs 3 × wild type, differentiation d2, vs 3 × knockout, expansion, vs 3 × wild type, expansion,Groups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Summary (written by the submitters)
Erythroid Krüppel Like Factor (EKLF/ KLF1) is a C2H2 zinc finger transcription factor that plays a critical role in all aspects of erythropoiesis. Mutations in KLF1 lead to diverse phenotypes ranging from mild to severe anemias. Patients with a heterozygous E325K mutation (CDA type IV) exhibit impaired erythroid terminal differentiation and increased presence of binucleate erythroblasts.

We previously showed that KLF1 is necessary for cell cycle exit and enucleation in mouse primary cells. In the current study we discovered that genes involved in cell motility, cell division, and mitotic pathways are all directly regulated by KLF1. Klf1-/- cells exhibit increased numbers of binucleated erythroblasts and DNA bridges, and differentiating Klf1-/- erythroblasts display an increased percentage of cytokinesis failure events and defective microtubule bundling. Klf1-/- erythroblasts produce frequent aberrant F-actin-rich membrane protrusions and anucleate cell fragments. Human CDA type IV cells exhibit similar patterns of dysregulation of cytokinesis and cell motility genes. Collectively, we show that KLF1 is necessary for maintaining the integrity of erythroid cell divisions by direct regulation of genes involved in cytokinesis and motility pathways during terminal erythroid differentiation.

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 GSE338783_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1495869 and SRA study SRP718347. Searching any of these in the dataset finder brings you back here.

Study design
3 × knockout, differentiation d2, vs 3 × wild type, differentiation d2, vs 3 × knockout, expansion, vs 3 × wild type, expansion,

Supports a case/control comparison: 6 samples read as cases, 6 as controls.

How we read this: 4 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.
