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
Mus musculus (mouse)
Samples
839 samples: 181 conditions, mostly in duplicateGroups 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)
Aging is characterized by progressive functional decline accompanied by distinct transcriptomic and epigenetic alterations. Although partial reprogramming via Yamanaka factors can reverse these signatures and improve cell function, toxicity and efficacy concerns limit their in vivo application, necessitating alternative geroprotective interventions.

Here, we develop an interpretable transcriptomic age predictor in human fibroblasts and perform a cDNA overexpression screen to identify factors that reprogram aged transcriptomes toward youthful states. This screen identifies the RNA-processing and splicing factor SRSF1 as a regulator of cellular aging that produces robust youthful transcriptional signatures without loss of cellular identity. In vitro, SRSF1 induction restores youthful phenotypes by reducing senescence, proteostatic stress and inflammatory signaling. In aged mice, inducible SRSF1 expression reduces frailty progression by 44% and is associated with a 14% extension of median lifespan (n = 9–10 per group). Our findings establish SRSF1 as a conserved regulator of aging and a promising geroprotective target.

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 GSE325735_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 PRJNA1441554 and SRA study SRP686727. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 362 samples.

How we read this: 181 replicated groups read from the first 400 of 839 sample titles; they account for 362 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.
