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)
Topic
MelanomaThis series is part of our curated briefing on it.
Samples
15 samples: 5 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.
Paper
Serum starvation-induced cholesterol reduction increases melanoma cell susceptibility to cytotoxic T lymphocyte killingScientific reports · 2025
Summary (written by the submitters)
Changes in cellular state has dramatic impact on cancer cell responsiveness to cytotoxic T lyphocyte (CTL) killing. In this study we tested serum starvation and increasing cytoskeleton of cancer cells. Serum starvation significantly upregulated the expression of genes involved in cholesterol biogenesis, which might be due a dramatic reduction in cellular cholesterol level.
Read the full summary ↓
Indeed, cholestrol reduction sensitized the human melanoma cell line A375 for CTL killing. However, increasing the cytoskeleton of cancer cells did not cause a change in cancer cell responsiveness to CTL killing, suggesting cholesterol-associated membrane composition other than cellular rigidity plays a more important role in determining cancer cell responsiveness to CTL killing.

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 GSE285537_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 PRJNA1204328 and SRA study SRP554467. Searching any of these in the dataset finder brings you back here.

Study design

Supports a between-group comparison across 15 samples.

How we read this: 5 replicated groups read from 15 sample titles; they account for 15 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.
