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.
Summary (written by the submitters)
Senescence has been shown to contribute to the progression of aging related diseases including degenerative disc disease (DDD). However, the mechanisms regulating senescence in the intervertebral disc (IVD) and other tissues/diseases remain poorly understood. Recently, in a CRISPRa genome-wide screen, our lab identified a previously uncharacterized zinc finger protein, ZNF865 (BLST), that regulates a wide array of genes related to protein processing, cell senescence and DNA damage repair.

Here, we demonstrate that ZNF865 expression is correlated with age and disease state in human patient IVD samples and mouse IVD. Utilizing CRISPR-guided gene modulation, we show that ZNF865 is necessary for healthy cell function and is a critical protein in regulating senescence and DNA damage in intervertebral disc cells, with implications for a wide range of tissues and organs. We also demonstrate that downregulation of ZNF865 induces senescence and upregulation mitigates senescence and DNA damage in human nucleus pulposus (NP) cells. Importantly, upregulation of ZNF865 shifts the chromatin landscape and gene expression profile of human degenerative NP cells towards a healthy cell phenotype. Collectively, our findings establish ZNF865 as a novel modulator of genome stability and senescence and as a potential therapeutic target for mediating senescence/DNA damage in senescence related diseases and disorders.

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 GSE311656_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 PRJNA1370086 and SRA study SRP649356. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 15 sample titles; they account for 12 of them. 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.
