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
18 samples: 5 conditions, mostly in triplicateGroups 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)
Caloric restriction (CR) extends lifespan in mammals but the stringent 20% reduction in food intake is challenging to sustain; therefore, validating pharmacological mimics is of high interest. It has been previously reported that a SERPINE1 mutation in an Amish cohort links to a 10-year lifespan increase and improved metabolism. SERPINE1 encodes for Plasminogen Activator Inhibitor-1 (PAI-1) which is a clinical predictor of vascular stiffness, hypertension, and diastolic dysfunction.

Moreover, PAI-1 amplifies accumulation of senescent cells as a component of the senescence associated secretory phenotype (SASP). Here, we compared hepatic transcriptomic profiles in mice after 8 weeks of CR, rapamycin, metformin, or the PAI-1 inhibitor TM5614 versus an ad libitum control. CR induced extensive changes (1087 genes downregulated, 1145 upregulated), while TM5614 showed the closest mimicry (211 down, 218 up), sharing ~50% of CR’s differentially expressed genes, including downregulated Il11ra1 and upregulated Per2, tied to longevity and metabolism. Rapamycin and metformin showed minimal overlap with CR. Gene Ontology analysis revealed CR and TM5614 downregulated metabolic pathways, and both countered gene-length-dependent transcription decline, an emerging measure of an aging transcriptomic landscape. TM5614 presents as a CR mimic, offering an alternative to CR to extend healthspan.

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 GSE299228_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 PRJNA1273112 and SRA study SRP590419. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 18 samples.

How we read this: 5 replicated groups read from 18 sample titles; they account for 18 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.
