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: 5 × Meni_O vs 5 × Meni_YGroups 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.

Summary (written by the submitters)
Aim To identify transcript level differences between healthy and osteoarthritis meniscus in human keen joint using RNA-seq.Methods human menisci were isolated from non-OA patients and OA patients during arthroscopic surgery (N=5). Based on the RNA sequencing, differentially expressed lncRNAs (DELs) and mRNAs (DEMs) were screened.Expression level of selected autophagy-related lncRNAs and mRNAs was validated by real-time qPCR.Results we identified 310 DELs and 320 DEMs, and found five upregulated and one downregulated autophagy-related DEMs.

After reverse prediction of miRNA, paired miRNA–lncRNA interactions and verification by RT-qPCR, the ceRNA regulatory networks were constructed consisting of two lncRNAs (PCAT19, CLIP1-ASA) and two mRNAs (BAG3 and HSP90AB1). Finally, GSEA indicated that the increased expressions of autophagy-related mRNAs inhibited the glycosaminoglycan biosynthesis in the degenerative meniscus.Conclusions for the first time ,we constructed an autophagy-related lncRNA-miRNA-mRNA regulatory ceRNA network based on RNA sequencing and experimental validation, which might provide new mechanistic insights and potential therapeutic targets for meniscal degeneration.

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 GSE263210_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 PRJNA1096285 and SRA study SRP499746. Searching any of these in the dataset finder brings you back here.

Study design
5 × Meni_O vs 5 × Meni_Y

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 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.
