Summary (written by the submitters)
Liver steatosis is a common cause of chronic liver disease. To investigate the molecular basis of hepatic steatosis, low-density lipoprotein receptor-deficient (LDLR -/-) mice were fed Western diet (WD, 42% of calories from fat) for 5, 14, or 42 days and evaluated against mice fed a normal laboratory diet. Histological analyses revealed that steatosis was detected as early as 14 days of WD feeding.

Bulk RNA sequencing demonstrated that WD feeding altered liver transcriptomes related to inflammation and cell adhesion consistent with the progression of liver steatosis. Previous studies determined that hepatocyte-specific deficiency of angiotensinogen (AGT), the unique substrate of the renin-angiotensin system (RAS), alleviates WD-induced hepatic steatosis in mice. However, the effects of hepatic AGT deficiency were not mimicked by pharmacological inhibition of the RAS, and the molecular mechanisms by which AGT deficiency protects against WD-induced steatosis is unknown. Therefore, liver transcriptomes were compared between hepatocyte-specific AGT deficient mice (hepAGT -/-) and their wild-type littermates (hepAGT +/+) after 14 days of WD feeding. Gene ontology analyses showed that upregulated genes in hepAGT -/- mice were enriched for metabolic processes and downregulated genes were enriched for cell division pathways. The integration analysis of the two RNA sequencing data identified 5 key genes, Smpd3, Dtl, Cdc6, Mki67, and Top2a, which were primarily associated with cell division processes in hepAGT +/+ mice and were suppressed in hepAGT -/- mice. In conclusion, hepatic AGT deficiency downregulated genes related to cell division during the progression of liver steatosis.

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 GSE291082_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 PRJNA1231527 and SRA study SRP567894. Searching any of these in the dataset finder brings you back here.
