Summary (written by the submitters)
MYC-driven Group-3 medulloblastomas (MB) are malignant pediatric brain cancers without cures. To define actionable metabolic dependencies, we identified upregulationof dihydrolipoyl transacetylase (DLAT), the E2-subunit of pyruvate dehydrogenasecomplex (PDC) in a subset of Group-3 MB with poor prognosis. DLAT was induced by c-MYC and targeting DLAT lowered TCA-cycle metabolism and glutathione synthesis in Group-3 MB cells.

We also noted upregulation of isocitrate dehydrogenase 1 (IDH1) in Group-3 MB. Remarkably, genetic and pharmacologic suppression of IDH1 epigenetically reduced c-MYC and downstream DLAT levels. DLAT is a central regulator of cuproptosis, a copper-dependent cell death mechanism induced by the copper ionophore elesclomol. DLAT expression in Group-3 MB cells correlated with increased sensitivity to cuproptosis. Elesclomol was CNS-penetrant and suppressed tumor growth in vivo in Group-3 MB animal models. Our data uncover an IDH1/c-MYC dependent vulnerability that regulates DLAT levels and can be targeted to kill Group-3MB by cuproptosis.

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 GSE278880_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 PRJNA1169346 and SRA study SRP536794. Searching any of these in the dataset finder brings you back here.

How we read this: Read from 36 sample titles: 28 distinct titles with little repetition. 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.
