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)
Samples
12 samples: 12 samples, each with a distinct title — no replicated groupsGroups 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)
Fanconi anemia (FA) is characterized by defective DNA repair and chronic p53 activation, predisposing to acute myeloid leukemia through persistent genomic instability. The molecular adaptations enabling cell survival under chronic stress remain poorly understood. This study investigates the role of ZMAT3, a p53 responsive RNA binding protein overexpressed in FA deficient cells, to elucidate its role in cellular adaptation.

Using FA patient fibroblasts and Fancg KO mouse models, we launched transcriptomic profiling, lipidomic, and functional analyses. RNA-seq and lipidomic analyses revealed unexpected alterations in sphingolipid metabolism upon ZMAT3 depletion, linked to ceramide accumulation and downregulation of ASAH1 (acid ceramidase). Functionally, ZMAT3 depletion increased DNA damage and enhanced ferroptosis susceptibility, an iron dependent cell death mechanism. Mechanistically, our results showed that ZMAT3 promotes ASAH1 expression, limits ceramide accumulation and protects cells from ferroptosis induced death which could participate to preleukemic clonal evolution and pointing to areas for further exploration in FA-associated malignancies.

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 GSE308873_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 PRJNA1333308 and SRA study SRP625455. Searching any of these in the dataset finder brings you back here.

Study design
12 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 12 sample titles: 12 distinct titles with little repetition. 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.
