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
11 samples: 3 × GES-1, H.pylori infected 6 hours, vs 3 × GES-1, pCDH vector control, vs 3 × GES-1, IGF2BP1 overexpression, vs 2 × GES-1, negative control,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)
Helicobacter pylori infection induces persistent transcriptional reprogramming in gastric epithelial cells. To identify downstream pathways regulated by IGF2BP1, RNA sequencing was performed in GES-1 cells with IGF2BP1 overexpression and H. pylori infection. Integrated analysis identified overlapping transcriptional programs associated with oxidative stress regulation and ferroptosis-related pathways.

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 GSE338493_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.

Raw reads on ENA ↗

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 PRJNA1494566 and SRA study SRP717671. Searching any of these in the dataset finder brings you back here.

Supports a case/control comparison: 6 samples read as cases, 5 as controls.

How we read this: 4 replicated groups read from 11 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.
