Paper
KMT2C deficiency drives transdifferentiation of double-negative prostate cancer and confer resistance to AR-targeted therapyCancer cell · 2025
Summary (written by the submitters)
Double-negative prostate cancer (DNPC), characterized by AR-null tumors with inherent plasticity, predominantly arises following androgen deprivation therapy (ADT). However, the cellular origin, signaling hierarchy, and treatment strategies for this lethal subtype remain unclear. Here, we demonstrate that the loss of KMT2C, a histone H3K4 methylation transferase preferentially mutated in the DNPC subtype, collaborates with ADT to drive the transformation of luminal tumors into DNPC.
Read the full summary ↓
Our findings reveal that DNPC arises from the transdifferentiation of luminal cells rather than basal cell expansion. This transdifferentiation is orchestrated by the upregulation of ΔNp63, induced by the dual inactivation of AR and KMT2C. Treatment with antiandrogens facilitates KMT2C binding to the enhancers of a subset of AR-regulated genes, compensating for AR inactivation to preserve the luminal identity. Among these, ARPP2 maintains its expression via KMT2C-dependent enhancer-promoter communication following AR inactivation.

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 GSE267775_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 PRJNA1112845 and SRA study SRP511353. Searching any of these in the dataset finder brings you back here.

Study design
26 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 26 sample titles: 26 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.
