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

Kidney cancerThis series is part of our curated briefing on it.
Samples
42 samples: 17 conditions, mostly in duplicateGroups 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)
Human isotopic tracer studies are fast becoming the gold standard model to study cancer metabolism in vivo. Analysed tissues are typically retrieved after surgical resection, which exposes them to a variable extent of warm ischaemia. Although standardised protocols are emerging, the effects of sampling conditions on the tissue metabolome remain understudied.
Read the full summary ↓
Here, we perform a 13C-glucose study coupled with metabolomic, transcriptomic, and proteomic profiling in patients with clear cell renal cell carcinoma (ccRCC) to assess the metabolic profile of tissues sampled intraoperatively, when blood supply is intact, versus post-surgical resection, which exposes the tissue to ischaemia. We show that ischaemia significantly affects the metabolic landscape of ccRCC, masking some critical features, such as suppressed gluconeogenesis. Furthermore, in orthotopic ccRCC-derived xenografts, we identified that prolonged exposure to ischaemia disrupts the tissue metabolome stability. Therefore, minimising tissue ischaemia is pivotal in accurately profiling cancer metabolism in these important and resource-intense patient studies.

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 GSE274774_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 PRJNA1147856 and SRA study SRP526230. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 39 samples.

How we read this: 17 replicated groups read from 42 sample titles; they account for 39 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.
