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.

2 samples: 2 samples, each with a distinct title — no replicated groupsGroups 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.
Paper
Hedgehog-interacting protein orchestrates alveologenesis and protects against bronchopulmonary dysplasia and emphysemaScience advances · 2025
Summary (written by the submitters)
A majority of the gas-exchange surface is generated during alveologenesis, and disruption of this process causes bronchopulmonary dysplasia (BPD) in preterm infants, characterized by alveolar simplification. BPD is a significant risk factor for adult emphysema, marked by alveolar loss. A comprehensive molecular understanding of alveologenesis and effective treatments for BPD and emphysema are still lacking.

Here, we show that the cells expressing Hhip, a gene associated with both BPD and emphysema, expand within the alveoli during alveologenesis, followed by hedgehog (Hh) inhibition and myofibroblast transition. Stromal-specific deletion of Hhip leads to aberrant persistence of SMA+ alveolar myofibroblasts, mediated by a hyperactive Hh-IGF1 axis. Conditional knockout animal and 3D stroma-stem cell organoid models demonstrate that loss of Hhip induces alveolar stem/progenitor cell senescence in a non–cell-autonomous manner. Alveolar simplification and BPD phenotypes induced by Hhip deletion can be partially rescued by IGF1 signaling blockade. We also observe the downregulation of Hhip expression and hyperactivation of Hh-IGF1 signaling in hyperoxia-induced BPD animal models. In addition, adult mice deficient in Hhip expression develop emphysema phenotype with abnormal alveolar myofibroblasts. Finally, we develop a therapeutic Fc-fused HHIP recombinant protein that attenuates BPD phenotypes in postnatal mice and emphysema in adult mice. These findings underscore the critical role of HHIP in coordinating alveologenesis and preventing BPD and emphysema by restricting Hh-IGF1 signaling.

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 GSE271417_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 PRJNA1131365 and SRA study SRP517809. Searching any of these in the dataset finder brings you back here.

Study design
2 samples, each with a distinct title — no replicated groups

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

How we read this: Read from 2 sample titles: 2 distinct titles with little repetition. 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.
