Functional Mapping of Epigenomic Regulators Uncovers Coordinated Tumor Suppression by the HBO1 and MLL1 ComplexesCancer discovery · 2025
Summary (written by the submitters)
Epigenetic dysregulation is widespread in cancer. However, the specific epigenetic 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 epigenetic regulators within autochthonous oncogenic KRAS-driven lung tumors.

We identified many previously unappreciated epigenetic tumor-suppressor and tumor-dependency genes. We show that a specific HBO1 complex and MLL1 complex are the most impactful tumor suppressive epigenetic regulators in lung cancer. Histone modifications generated by HBO1 complex are frequently reduced in human lung adenocarcinomas. HBO1 and MLL1 complexes regulate chromatin accessibility at shared genomic regions, lineage fidelity and expression of canonical tumor suppressor genes. The HBO1 and MLL1 complexes are epistatic during lung tumorigenesis, and their functional correlation is conserved in human cancer cell lines. Together, these results provide a phenotypic roadmap of epigenetic regulators in lung tumorigenesis in vivo.

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 GSE282851_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1190859 and SRA study SRP547691. Searching any of these in the dataset finder brings you back here.

Study design
8 × sub_library vs 2 × scr_library

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 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.
