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
29 samples: 6 conditions, mostly with about 5 replicates eachGroups 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
Identification of Novel Small-Molecule Inhibitors Targeting KDM5B and Evaluation of Their Antitumour EffectsCancer medicine · 2026
Summary (written by the submitters)
KDM5B, a member of the KDM5 family of histone demethylases, functions as a key epigenetic regulator by removing di- and trimethyl groups from H3K4 (H3K4me2/3), thereby promoting transcriptional repression. It is involved in fundamental biological processes, including development, stem cell maintenance, and tumorigenesis, and its dysregulation has been associated with multiple cancer types.
Read the full summary ↓
Given its critical role in cancer biology, KDM5B has emerged as an attractive target for therapeutic intervention. Therefore, we conducted a screening campaign to identify novel KDM5B inhibitors. In this study, we investigated whether the KDM5B inhibitors JB-157 and JB-161, identified through our screening, exert antitumor effects.

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 GSE319664_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 PRJNA1424927 and SRA study SRP677709. Searching any of these in the dataset finder brings you back here.

Study design
6 conditions, mostly with about 5 replicates each
Control ×5 JB-157 ×5 JB-161 ×5 JB-157, 5-FU ×5 JB-161, 5-FU ×5 5-FU ×4

Supports a between-group comparison across 29 samples.

How we read this: 6 replicated groups read from 29 sample titles; they account for 29 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.
