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.
Summary (written by the submitters)
The efficacy of calorie restriction (CR) in enhancing cognition, promoting healthy aging, and extending lifespan is well-established. However, the influence of the apolipoprotein E (APOE) genotype, a key modifier of aging and age-related disorder, on the beneficial effects of CR remains unclear. In this study, we utilized humanized APOE mouse models expressing APOE2, APOE3, or APOE4 (referred to as E2, E3, and E4 mice, respectively).

These mice were subjected to either standard ad libitum (AL) feeding or 30% CR feeding, starting at 12 months and continuing until 20 months of age (N = 11–20/genotype/group, mixed sex). To investigate how APOE genotype modifies brain transcriptional responses to CR, we performed bulk RNA sequencing on brain cortical tissues including 69 samples from all the groups. The RNA-seq data were adjusted for flow cell, exonic coverage, and extraction batch effects. Using preprocessed gene expression profiles, we conducted weighted gene co-expression network analyses (WGCNA) and differential gene expression analyses. Consistently across both approaches, our results revealed an upregulation of the cholesterol synthesis pathway in E3- and E4-CR mice, but not in E2-CR mice. CR related DEGs also predicted the enhanced myelination, which were further validated through immunofluorescent staining for PDGFRA (an OPC marker), ASPA (an OL marker), and MBP (a myelin sheath protein), as well as electron microscopy of corpus callosum tissues in E3- and E4-CR mice, but not in E2-CR mice. Overall, our study highlights the critical role of APOE genotype in modulating the brain’s response to CR, emphasizing the importance of considering APOE genotype in developing prevention strategies for aging and age-related disorders.

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 GSE286644_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 PRJNA1209964 and SRA study SRP557094. Searching any of these in the dataset finder brings you back here.

Study design
A cohort of 69 individual samples

The grouping that defines any comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Sample titles run BU-LF-3 … BU-LF-160 and carry no group information.
