Abstract

Metabolic reprogramming is a hallmark of cellular transformation, yet little is known about metabolic changes that accompany tumor metastasis. Here we show that primary breast cancer cells display extensive metabolic heterogeneity and engage distinct metabolic programs depending on their site of metastasis. Liver-metastatic breast cancer cells exhibit a unique metabolic program compared to bone- or lung-metastatic cells, characterized by increased conversion of glucose-derived pyruvate into lactate and a concomitant reduction in mitochondrial metabolism. Liver-metastatic cells displayed increased HIF-1α activity and expression of the HIF-1α target Pyruvate dehydrogenase kinase-1 (PDK1). Silencing HIF-1α reversed the glycolytic phenotype of liver-metastatic cells, while PDK1 was specifically required for metabolic adaptation to nutrient limitation and hypoxia. Finally, we demonstrate that PDK1 is required for efficient liver metastasis, and its expression is elevated in liver metastases from breast cancer patients. Our data implicate PDK1 as a key regulator of metabolism and metastatic potential in breast cancer.

  • PDK1 expression was elevated in breast cancer liver metastases compared to primary tumor specimens.

    “Notably, PDK1 expression was elevated in breast cancer liver metastases compared to primary tumor specimens, further supporting the notion that PDK1 expression is particularly important for the growth and survival of breast cancer cells within the liver microenvironment.”

  • Breast metastases to the liver are highly dependent on glycolysis for survival in comparison to bone and lung metastases.

    “Consistent with the concept that hepatic hypoxia and the associated glycolytic phenotype in periportal regions of the liver provide a barrier for metastatic colonization, Dupuy and colleagues observed that breast metastases to the liver are highly dependent on glycolysis for survival in comparison to bone and lung metastases (111).”

  • The metabolic reprogramming of liver-metastatic breast cancer cells was largely dependent on the HIF-1 target gene PDK1.

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.
