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.

MelanomaThis series is part of our curated briefing on it.
Samples
22 samples: 22 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.

Summary (written by the submitters)
Melanoma remains one of the most aggressive and treatment-resistant cancers, emphasizing the need for novel therapeutics. In our current study we report a peptide-based approach as potential therapeutic. The expression and role of Catestatin(CST), a Chromogranin A(CgA)-derived peptide with immunomodulatory and reparative properties in skin injury led us to examine its connection to melanoma.

Advancing melanoma stages showed decreased CST expression. CST administration to patient derived cells and melanoma cell lines A375, B16F10, SKMEL28 revealed increased apoptosis, decreased proliferation and metastatic ability of the melanoma cells without affecting cell viability for normal skin fibroblasts. CST reduced growth kinetics and tumor weight in B16F10 derived in vivo melanoma tumors. Transcriptomic analyses of catestatin treated human cell line and mouse tumor revealed downregulation of hypoxia, collagen remodeling, epithelial to mesenchymal transition pathways (EMT), stress adaptive responses that are accountable for melanoma progression. In Vemurafenib-resistant A375 cells, CST increased apoptosis and repressed multiple resistance associated genes. These results highlight CST as a promising therapeutic candidate capable of opposing melanoma progression and overcoming resistance to current targeted treatments.

This dataset
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 GSE312638_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 PRJNA1362965. Searching any of these in the dataset finder brings you back here.

Study design
22 samples, each with a distinct title — no replicated groups

Supports a case/control comparison: 11 samples read as cases, 11 as controls.

How we read this: Read from 22 sample titles: 22 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.
