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.

Paper
Role of Forkhead Box P3 in IFNγ-Mediated PD-L1 Expression and Bladder Cancer Epithelial-to-Mesenchymal TransitionCancer research communications · 2024
Summary (written by the submitters)
Antagonism of the PD-1/PD-L1 axis is a critical therapeutic strategy for advanced bladder cancer patients. IFNg functions as a key regulator of PD-L1 in both immune as well as cancer cells. Forkhead Box P3 (FOXP3) is a transcription factor synonymous in T regulatory cell function, but with increasingly described functions in cancer cells.
Read the full summary ↓
Here we investigated the relationship between FOXP3 and PD-L1 in bladder cancer. We showed that FOXP3 is critical in the ability for IFNg to activate PD-L1 in bladder cancer cells. FOXP3 can bind to the PD-L1 promoter and induces a gene program that leads to regulation of multiple immune-related genes and genes involved in epithelial-to-mesenchymal transition. Using in vitro and in vivo human and murine models, we showed that FOXP3 can regulate bladder cancer differentiation as well as promote metastases. Furthermore, FOXP3 may be a convergent factor for multiple activators of PD-L1 including by cisplatin.

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 GSE268243_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 PRJNA1115527 and SRA study SRP509514. Searching any of these in the dataset finder brings you back here.

Study design
3 × KO,UTR,sample vs 3 × KO,IFNg,sample vs 3 × WT,UTR,sample vs 3 × WT,IFNg,sample

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
