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
48 samples: 48 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.
Paper
Activating transcription factor 4 plays a major role in shaping the transcriptional response to isoginkgetin in HCT116 cellsScientific reports · 2024
Summary (written by the submitters)
Activating transcription factor 4 (ATF4) is activated during cellular stress through a pathway called the integrated stress response (ISR). We had previously reported that the splicing inhibitor isoginkgetin (IGG) activates ATF4 and ATF4-dependent transcripts. To determine the role of ATF4 in the transcriptional response to IGG, we used tandem CRISPR cas9 gene editing to create an ATF4 deficient HCT116 (colon cancer) cell line.

We completed RNA sequencing on HCT116 parental and HCT116 ATF4 deficient cells treated with IGG, and thapsigargin (Tg), a positive control for ATF4 activation. We found that IGG led to the differential expression of 76 transcripts, and 58 of these were dependent on ATF4. Tg led to a far more robust transcriptional response, which appeared to be less ATF4 dependent.

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 GSE249009_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 PRJNA1047008 and SRA study SRP475085. Searching any of these in the dataset finder brings you back here.

Study design
48 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 48 sample titles: 48 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.
