Summary (written by the submitters)
Molecular subtyping plays a vital role in the treatment of breast cancer, however, current clinical outcomes remain unsatisfactory despite having multiple molecular subtypes available, particularly for triple-negative breast cancers. Henceforth, our research primarily focuses on traditional molecular subtyping by utilizing transcriptome sequencing and ATAC-seq sequencing techniques to classify both tumor tissues and adjacent tissues from patients with breasts cancers into distinct groups.

Through this process, we aim to identify key gene expressions involved in the development of breasts cancers as well as epigenetic characteristics influenced by alterations in chromatin accessibility patterns. Subsequently, employing conventional methods used for classifying breasts cancers into different molecular types enables us to further investigate significant variations observed specifically within triple-negative breasts cancers regarding their gene expression profiles and chromatin accessibility patterns. Lastly, utilizing data from TCGA database pertaining exclusively to cases involving triple-negative breasts cancers allows us to conduct regression analyses concerning our aforementioned findings while simultaneously selecting relevant molecular models closely associated with this particular subtype of breasts malignancy. Additionally evaluating how these differentially expressed genes influence prognosis through prognostic modeling analysis tailored towards predicting outcomes solely within cases involving individuals diagnosed with triple negative-breast malignancies will enable us ultimately construct an innovative model incorporating both gene expressions along with chromatin accessibility patterns as distinguishing features providing more substantial guidance towards improving clinical treatments targeting individuals afflicted by such conditions.

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 GSE254212_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1069018 and SRA study SRP485947. Searching any of these in the dataset finder brings you back here.

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

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 19 sample titles: 19 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.
