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
Homo sapiens (human)
Topic
Myelodysplastic syndromesThis series is part of our curated briefing on it.
Samples
12 samples: 3 × MUTZ-1 cells, shNUDT21 vs 3 × SKM-1 cells, sh control vs 3 × SKM-1 cells, shNUDT21 vs 2 × MUTZ -1cells, sh controlGroups 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)
During mRNA maturation, splicing, capping and polyadenylation are its three main steps. And polyadenylation is the last key step in mRNA maturation, where the 3' end of pre-mRNA is cleaved and polyA sequence is added, which plays an important role in the stability of mRNA and its cellular function. NUDT21, which we report here, is a key regulator involved in polyadenylation in mRNA maturation and plays an extremely important role in variable polyadenylation.

And we found that NUDT21 was highly expressed in MDS cells and that NUDT21 had a significant effect on the biological functions of MDS cells, especially in the transformation of MDS into AML. Therefore, our data report a specific gene profile of MDS cell lines after NUDT21 knockdown, which provides a new biomarker for clinical judgement of whether the disease has progressed in MDS patients, and provides new ideas on whether NUDT21 downstream regulatory genes, such as XAF1, may be new targets for MDS therapy.

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 GSE280172_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 PRJNA1176693 and SRA study SRP540469. Searching any of these in the dataset finder brings you back here.

Study design
3 × MUTZ-1 cells, shNUDT21 vs 3 × SKM-1 cells, sh control vs 3 × SKM-1 cells, shNUDT21 vs 2 × MUTZ -1cells, sh control

Supports a between-group comparison across 11 samples.

How we read this: 4 replicated groups read from 12 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.
