Combined Inhibition of HRAS and MEK Induces Tumor Regression and Restores Myogenic Differentiation in HRAS-Mutant RhabdomyosarcomaCancer research · 2026
Summary (written by the submitters)
Hyperactive RAS signaling drives tumorigenesis in PAX 3/7::FOXO1 fusion-negative rhabdomyosarcoma (FN-RMS). Despite the frequency of these mutations, indirect RAS pathway-directed therapies have been ineffective for RAS-driven RMS. Farnesyltransferase (FTase) inhibitors (FTIs), such as tipifarnib, inhibit HRAS membrane localization and blunt HRAS effector signaling, leading to an antitumor effect in HRAS-mutant FN-RMS preclinical models.
Read the full summary ↓
Response to FTase inhibition is limited by adaptive feedback reactivation of ERK signaling and upregulation of wild-type (WT) RAS. We found that the combination of HRAS suppression with FTI and MEK inhibition (MEKi) impaired ERK reactivation and reduced ERK transcriptional output in HRAS-mutant RMS models. Co-targeting FTase and MEK restrained tumor progression and induced terminal myogenic differentiation. These findings highlight an effective combinatorial strategy and support its preclinical translation for patients with HRAS-mutant RMS.

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 GSE312030_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 PRJNA1372080 and SRA study SRP650422. Searching any of these in the dataset finder brings you back here.
