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
Breast cancerThis series is part of our curated briefing on it.
Samples
22 samples: 11 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)
Long noncoding RNA HOTAIR (HOX antisense intergenic RNA) is an important regulator of breast cancer metastasis. Studies showed that HOTAIR reprograms chromatin state through interacting with Polycomb Repressive Complex 2 (PRC2) to promote breast cancer metastasis. However, it is unclear if there exist other HOTAIR-binding factors which participate in promoting breast cancer metastasis.

In the current study, we utilized mass spectrometry (ChIRP-MS) to comprehensively identify RNA-binding proteins (RBPs) associated with HOTAIR. We also performed a high-throughput CRISPR screen to investigate HOTAIR-interacting proteins involved in cell metastasis. We found that many m6A-reader proteins were involved in this progress, including YTHDF3, which is a newly identified HOTAIR partner. We further demonstrated that HOTAIR and YTHDF3 co-regulated the expression of several metastasis-associated genes by modifying their chromatin accessibility in breast cancer cells. Altogether, our work detailed the functional interactome of HOTAIR involved in promoting breast cancer cell metastasis, and suggested a mechanism whereby HOTAIR regulates chromatin state in cooperation with the m6A-reader YTHDF3.

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 GSE215289_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 PRJNA889709 and SRA study SRP402110. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 22 samples.

How we read this: 11 replicated groups read from 22 sample titles; they account for 22 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.
