Abstract

Disrupted regulation of cellular processes is considered one of the hallmarks of cancer. We analyze metabolomic and transcriptomic profiles jointly collected from breast cancer and hepatocellular carcinoma patients to explore the associations between the expression of metabolic enzymes and the levels of the metabolites participating in the reactions they catalyze. Surprisingly, both breast cancer and hepatocellular tumors exhibit an increase in their gene-metabolites associations compared to noncancerous adjacent tissues. Following, we build predictors of metabolite levels from the expression of the enzyme genes catalyzing them. Applying these predictors to a large cohort of breast cancer samples we find that depleted levels of key cancer-related metabolites including glucose, glycine, serine and acetate are significantly associated with improved patient survival. Thus, we show that the levels of a wide range of metabolites in breast cancer can be successfully predicted from the transcriptome, going beyond the limited set of those measured.

  • In the literature, concatenated multi-omics data in a joint matrix is used as input to classical machine learning methods such as decision trees, naive Bayes, artificial neural networks, support vector machines, k-nearest neighbours, random forests and K-Star.

    “The concatenated multi-omics data (in the form of a joint matrix) is provided as input to different classical ML methods such as DT (decision tree) (Quinlan, 1993), NB (naive Bayes) (Domingos and Pazzani, 1997), ANN (artificial neural networks) (Bishop, 1995), SVM (support vector machine) (Vapnik, 1995), KNN (k-nearest neighbors) (Altman, 1992), RF (random forest) (Breiman, 2001) and K-Star (Cle”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
