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
19 samples: 17 distinct titles, 1 of them repeatedGroups 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)
Fusobacterium polymorphum has been implicated in oral squamous cell carcinoma, yet its widespread presence in the oral cavity raises questions about whether different clinical isolates exert distinct effects on host cells. To explore host transcriptional responses, we performed transcriptomic profiling of dysplastic oral keratinocytes (DOK) following exposure to F.
Read the full summary ↓
polymorphum isolates derived from across the oral epithelial disease spectrum. The host transcriptomic response revealed a broadly shared pro-inflammatory signature across all isolates, regardless of their clinical origin. However, expression of genes and pathways associated with cell proliferation and related signaling processes varied among isolates and correlated with the dysplasia severity of the lesions from which the strains were derived. These findings suggest that while F. polymorphum isolates elicit a common inflammatory response in epithelial cells, variation in host transcriptional programs linked to proliferation may reflect differences in their biological impact.

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 GSE324461_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 PRJNA1435191 and SRA study SRP682635. Searching any of these in the dataset finder brings you back here.
