Functional Mapping of Epigenomic Regulators Uncovers Coordinated Tumor Suppression by the HBO1 and MLL1 ComplexesCancer discovery · 2025
Summary (written by the submitters)
Epigenomic dysregulation is widespread in cancer. However, the specific epigenomic regulators and the processes they control to drive cancer phenotypes are poorly understood. We employed a novel, scalable and high-throughput in vivo method to perform iterative functional screens of >250 epigenomic regulators within autochthonous oncogenic KRAS-driven lung tumors.

We identified many previously unappreciated epigenomic tumor-suppressor and tumor-dependency genes. We show that a specific HBO1 complex and MLL1 complex are robust tumor suppressors in lung cancer. Histone modifications generated by HBO1 complex are frequently diminshed in human lung adenocarcinomas and is associated with worse clinical features. HBO1 and MLL1 complexes co-occupy shared genomic regions, impacting chromatin accessibility, expression of canonical tumor suppressor genes and lineage fidelity. The HBO1 complex is epistatic with the MLL1 complex and other tumor suppressor genes in lung adenocarcinoma development. Collectively, these results uncover HBO1 and MLL1 complexes as critical functional modules restraining lung adenocarcinoma development and provide a in vivo phenotypic roadmap of epigenomic regulators in lung tumorigenesis.

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 GSE303178_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 PRJNA1294294 and SRA study SRP602400. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly in duplicate
KPTC_H3K4me3 ×3 KPTC_IgG ×2 KPTC_H3K14ac ×2 KPTC_KMT2A ×2 KPTC_KAT7 ×2 KPTC_CTCF ×1

Supports a between-group comparison across 11 samples.

How we read this: 5 replicated groups read from 12 sample titles; they account for 11 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.
