TFE3 fusions direct an oncogenic transcriptional program that drives OXPHOS and unveils vulnerabilities in translocation renal cell carcinomabioRxiv : the preprint server for biology · 2024
Summary (written by the submitters)
Translocation renal cell carcinoma (tRCC) is an aggressive subtype of kidney cancer driven by TFE3 gene fusions, which act via poorly characterized downstream mechanisms. Here we report that TFE3 fusions transcriptionally rewire tRCCs toward oxidative phosphorylation (OXPHOS), contrasting with the highly glycolytic metabolism of most other RCCs.
Read the full summary ↓
The transcriptional program driven by TFE3 fusions sustains high NRF2 signaling and glutathione production, which offsets reactive oxygen species generated by OXPHOS but renders tRCC cells sensitive to reductive stress. Genome-scale CRISPR screening identifies tRCC-selective vulnerabilities linked to maintaining this metabolic balance, including EGLN1, which hydroxylates HIF-1α and targets it for proteolysis. Inhibition of EGLN1compromises tRCC cell growth by stabilizing HIF-1a and promoting glycolytic reprogramming. Our study defines a distinctive tRCC-essential metabolic program driven by TFE3 fusions and nominates EGLN1inhibition as a therapeutic strategy to counteract fusion-induced metabolic rewiring.

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 GSE266530_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 PRJNA1107519 and SRA study SRP505617. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 32 samples.

How we read this: 16 replicated groups read from 32 sample titles; they account for 32 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.
