Hepatic BMAL1 and HIF1α regulate a time-dependent hypoxic response and prevent hepatopulmonary-like syndromeCell metabolism · 2024
Summary (written by the submitters)
The transcriptional response to hypoxia is temporally regulated yet the molecular underpinnings and physiological implications are unknown. We examined herein the roles of hepatic Bmal1 and Hif1a in the circadian response to hypoxia in mice. We found that the majority of the transcriptional response to hypoxia is dependent on Bmal1 or Hif1a, through shared and distinct roles that are daytime determined.

We further show that HIF1a accumulation upon hypoxia is temporally regulated and Bmal1-dependent. Unexpectedly, mice lacking both hepatic Bmal1 and Hif1a are hypoxemic and exhibit increased mortality upon hypoxic exposure in a daytime-dependent manner. These mice display mild liver dysfunction with pulmonary vasodilation likely due to ERK activation, endothelial nitric oxide synthase and nitric oxide accumulation in lungs, suggestive of hepatopulmonary syndrome. Our findings indicate that hepatic BMAL1 and HIF1a are key time-dependent regulators of the response to hypoxia and provide molecular insight on the pathophysiology of hepatopulmonary syndrome.

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 GSE254438_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 PRJNA1070580 and SRA study SRP486521. Searching any of these in the dataset finder brings you back here.
