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
20 samples: 5 conditions, mostly with about 4 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.

Summary (written by the submitters)
Non-enzymatic reactions in glycolysis lead to the accumulation of methylglyoxal (MGO), a reactive precursor to advanced glycation end-products (AGEs), which has been hypothesized to drive obesity and aging-associated pathologies. A combination of nicotinamide, lipoic acid, thiamine, pyridoxamine, and piperine (Gly-Low), was identified to lower glycation by reducing MGO and MGO-derived AGE, MG-H1, in mice.

Administration of Gly-Low reduced food consumption, lowered body weight, improved insulin sensitivity, and increased survival in both leptin receptor-deficient (Leprdb) and wild-type C57B6/J mice. Unlike caloric restriction, Gly-Low modulated hypothalamic signaling by upregulating mTOR pathway signaling to inhibit ghrelin-mediated hunger response. Gly-Low also slowed hypothalamic aging and increased survival when administered as a late-life intervention, suggesting its potential benefits in ameliorating age-associated decline by inducing voluntary caloric restriction and reducing glycation.

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 GSE234483_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 PRJNA981518 and SRA study SRP441857. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly with about 4 replicates each
acute-treated control ×5 acute-treated Gly-Low ×4 old control ×4 young control ×4 old Gly-Low ×3

Supports a case/control comparison: 4 samples read as cases, 8 as controls.

How we read this: 5 replicated groups read from 20 sample titles; they account for 20 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.
