Summary (written by the submitters)
Tumor-initiating cells (TICs) tend to reside in poorly vascularized regions of tumors and are subjected to nutrient stress. How TICs activate metabolic plasticity for adapting to periods of low nutrient availability, especially during glucose-limiting conditions, has remained unclarified. Here, we discover that lung TICs can induce a metabolic switch from glucose towards ketone utilization specifically during glucose deprivation, whereas bulk, non-TIC cells are unable to do so.

Through ex vivo supplementation of ketones or keeping mice on prolonged ketogenic diet, we determine the functional importance of ketones in maintaining the growth and tumor-initiating property of lung TICs. Metabolomics, genomics and metabolic flux tracing studies reveal that ketones feed into ketolysis, fatty acid synthesis and de novo lipogenesis pathways. Surprisingly, ketogenic diet programs the metabolic addiction of TICs towards ketolysis, and this paradoxically induces their therapeutic sensitivity towards the inhibition of the monocarboxylate transporter, MCT1, which imports ketones into cells. Additionally, pharmacological inhibition of fatty acid synthase (FASN) also exerts a more pronounced anti-tumorigenic response in the context of a ketogenic diet. MCT1 function is regulated by the chaperone protein, CD147, and its loss is sufficient to ablate lung TICs under glucose-limiting conditions in vitro and in vivo. Our data reveal a metabolic switch that lung TICs adopt to overcome nutrient stress, and provide the mechanistic bases for how diet manipulation can alter the course of cancer progression or enhance the efficacy of targeted therapy in a context-dependent manner.

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 GSE299342_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 PRJNA1273944 and SRA study SRP590992. Searching any of these in the dataset finder brings you back here.
