Paper
Somatic CRISPR tumorigenesis and multiomic analysis reveal a pentose phosphate pathway disruption vulnerability in MPNSTsScience advances · 2025
Summary (written by the submitters)
Malignant Peripheral Nerve Sheath Tumors (MPNSTs) are aggressive and chemo-resistant sarcomas with poor overall survival. Loss of tumor suppressors CDKN2A (~80%) or P53 (~20%) is a signature event in MPNST development. Here, we use CRISPR/Cas9 somatic tumorigenesis mouse models to mechanistically compare CDKN2A and P53 loss transcriptomic and metabolic differences, leading to therapeutic vulnerabilities in MPNSTs.

Multi-omic analyses identified the pentose phosphate pathway (PPP) and regulation of NADPH metabolism as critical metabolic vulnerabilities in the CDKN2A-deleted MPNSTs. Disruption of glucose-6-phosphate dehydrogenase (G6PD), the rate-limiting step in the PPP, slowed CDKN2A-deleted MPNST growth, yet sensitized both genotypes of MPNSTs to standard-of-care chemotherapy. Moreover, the redox-regulated transcription factor NRF2 controlled G6PD activity in these tumors. Genomic analysis of patient samples showed a NRF2 gene signature that correlated with tumor transformation, further underscoring this pathway as a therapeutic target. This work identifies the G6PD/NADPH axis as a central metabolic vulnerability in MPNSTs.

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 GSE275277_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 PRJNA1150162 and SRA study SRP527570. Searching any of these in the dataset finder brings you back here.
