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.
Organism
Homo sapiens (human)
Samples
10 samples: 8 × PDR_SGroups 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.

The multifaceted role of vitreous hyalocytes: Orchestrating inflammation, angiomodulation and erythrophagocytosis in proliferative diabetic retinopathyJournal of neuroinflammation · 2024
Summary (written by the submitters)
Despite great advancements in proliferative diabetic retinopathy (PDR) therapy over the last decades, one third of treated patients continue to lose vision. Vitreous macrophages called hyalocytes have been implied in the pathogenesis of vitreoretinal proliferative disease previously but little is known about their role in PDR. In this study, we address molecular and cellular alterations of the PDR vitreous, in order to assess the potential contribution of hyalocytes to PDR development.
Read the full summary ↓
A total of 55 patients were included in this study encompassing RNA-Sequencing analysis of vitreous hyalocytes from PDR and control patients, multiplex immunoassay and ELISA analysis of undiluted vitreous samples and isolation and immunohistochemical staining of cultured porcine hyalocytes. Our transcriptional analysis revealed an enhanced inflammatory signature of hyalocytes contributing to the cytokine pool within the PDR vitreous by expressing, among others, interleukin-6. The data further indicate an expression shift, involving angiopoietin-2, in PDR hyalocytes converting them to a proangiogenic cellular component, which may mediate formation of retinal neovascularization, hallmark of PDR. Finally, our data suggest a role of vitreous macrophages in erythrophagocytosis and, thereby, removal of vitreous hemorrhage, a severe complication of PDR. Immunomodulation of hyalocytes may thus prove an essential novel therapeutical approach in diabetic vitreoretinal disease.

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 GSE276892_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.

Raw reads on ENA ↗

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 PRJNA1159345 and SRA study SRP531910. Searching any of these in the dataset finder brings you back here.
