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.

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
Monocytes from inflammatory arthritis patients accumulate methotrexate and their transcriptome predicts methotrexate clinical responseCellular and molecular life sciences : CMLS · 2026
Summary (written by the submitters)
Arthritis patients receive a weekly low-dose of Methotrexate (MTX) as a first-line disease modifying anti-rheumatic drug. Following low-dose administration, MTX typically reaches peak plasma concentrations after 1-2 hours, and almost completely disappears from the circulation by 24 hours.
Read the full summary ↓
However, the kinetics of the anti-inflammatory action of MTX in monocytes after the initial dose is unknown.To address this issue, we carried out a phase I clinical trial (METOMAC) in which peripheral blood from 6 healthy donors receiving a single dose of MTX was analyzed at distinct time points after drug intake (3 hours, 24 hours, 120 hours). RNA-seq on monocytes isolated at the distinct timepoints was determined.

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 GSE289101_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 PRJNA1221539 and SRA study SRP562706. Searching any of these in the dataset finder brings you back here.
