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: 6 conditions, mostly in triplicateGroups 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)
Dysregulated RNA splicing is activated in tumors; however, the metabolic landscape and consequent implications of this process remain largely unexplored. In this study, we identified exon skipping in Ste20-like kinase (SLK), resulting in a variant isoform of SLK (SLKv), which promotes glycolysis in tumor cells. Mechanistically, SLKv enhances the activity of enolase 1 (ENO1) by binding and phosphorylating the ENO1 serine 2 residue.

This modification increases the efficiency of ENO1 in catalyzing the production of phosphoenolpyruvate (PEP). Notably, the accumulation of PEP further accelerates glycolysis by binding to and activating the glycolytic enzyme hexokinase 2 (HK2), phosphofructokinase muscle (PFKM), and phosphoglycerate mutase 1 (PGAM1). Meanwhile, transforming growth factor β (TGFβ) promotes exon skipping of SLK by upregulating the splicing factor KH RNA binding domain containing, signal transduction associated 1 (KHDRBS1). The application of antisense oligonucleotides (ASO) that target SLKv hinders glycolysis and tumorigenesis. These findings establish SLKv as a critical promoter of glycolysis and present a novel metabolic target for cancer therapy.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE299345_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.

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
