Dietary methionine deprivation enhances renal resilience against ischemia-reperfusion injury in mice through modulation of glucose oxidationCommunications biology · 2025
Summary (written by the submitters)
Renal ischemia-reperfusion injury (IRI) is a leading cause of acute kidney injury (AKI) and presents significant challenges during kidney transplantation. Due to the detrimental effects of IRI on kidney function and the lack of effective intervention strategies, we conduct a multi-omics study on surgically induced mouse IRI, revealing a modulatory role for the metabolite S-adenosylmethionine (SAM) in AKI development.

Our metabolic analysis of clinical samples establishes a link between various AKI conditions and marked elevations in serum SAM, underlying its potential as a biomarker for diagnosis. Furthermore, we find that short-term dietary methionine deprivation, which reduces circulating methionine and kidney SAM levels, effectively enhances renal resilience against IRI. In vivo isotopic tracing demonstrates that this diet preconditions kidney metabolic programs, enhancing glucose and fatty acid oxidation in preparation for IRI. Particularly, the activation of pyruvate dehydrogenase, which produces acetyl-CoA to fuel the tricarboxylic acid (TCA) cycle, highlights an energy-efficient strategy of glucose metabolism that is essential for the protective effects of dietary methionine deprivation.

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 GSE283374_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 PRJNA1193550 and SRA study SRP549048. Searching any of these in the dataset finder brings you back here.
