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
18 samples: 18 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
Disassembly of the TRIM56-ATR complex promotes cytoDNA/cGAS/STING axis-dependent intervertebral disc inflammatory degenerationThe Journal of clinical investigation · 2024
Summary (written by the submitters)
Given the leading cause of disability worldwide, low back pain (LBP) is recognized as a pivotal socio-economic challenge to the aging population, which is importantly attributed to intervertebral disc degeneration (IVDD), a highly prevalent affliction of aging. Elastic nucleus pulposus (NP) tissue is essential for maintenance of IVD structural and functional integrity.

Native NP cells exhibit crucial functions for regulating extracellular matrix homeostasis, constructing an accommodating biomechanical environment and maintaining the gelatinous property of NP tissue. The accumulation of senescent NP cells with inflammatory hypersecretory phenotype due to aging and other damaged factors is a distinctive hallmark of IVDD initiation and progression. In this study, we revealed a mechanism of IVDD progression in which aberrant genomic DNA damage promoted NP cell inflammatory senescence via activation of cGAS-STING axis. cGAS-STING axis activation drove inflammatory phenotype acquisition and inflammatory hypersensitivity to damaged signals of senescent NP cells via NF-κB pathway-mediated transcriptional modulation. And the administration of H-151 revealed that STING pharmacological inhibitor notably suppressed the inflammatory response formation and senescence associated screctory phenotype (SASP) acquisition of senescent cells. Furthermore, blocking STING activation could suppress NF-κB pathway-mediated transcriptional remodeling and inflammatory phenotype acquisition in senescent NP cells.

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 GSE245147_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 PRJNA1027236 and SRA study SRP465994. Searching any of these in the dataset finder brings you back here.

Study design
18 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 18 sample titles: 18 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.
