Abstract

Here, we propose a new model for understanding the Warburg effect in tumor metabolism. Our hypothesis is that epithelial cancer cells induce the Warburg effect (aerobic glycolysis) in neighboring stromal fibroblasts. These cancer-associated fibroblasts, then undergo myo-fibroblastic differentiation, and secrete lactate and pyruvate (energy metabolites resulting from aerobic glycolysis). Epithelial cancer cells could then take up these energy-rich metabolites and use them in the mitochondrial TCA cycle, thereby promoting efficient energy production (ATP generation via oxidative phosphorylation), resulting in a higher proliferative capacity. In this alternative model of tumorigenesis, the epithelial cancer cells instruct the normal stroma to transform into a wound-healing stroma, providing the necessary energy-rich micro-environment for facilitating tumor growth and angiogenesis. In essence, the fibroblastic tumor stroma would directly feed the epithelial cancer cells, in a type of host-parasite relationship. We have termed this new idea the "Reverse Warburg Effect." In this scenario, the epithelial tumor cells "corrupt" the normal stroma, turning it into a factory for the production of energy-rich metabolites. This alternative model is still consistent with Warburg's original observation that tumors show a metabolic shift towards aerobic glycolysis. In support of this idea, unbiased proteomic analysis and transcriptional profiling of a new model of cancer-associated fibroblasts (caveolin-1 (Cav-1) deficient stromal cells), shows the upregulation of both (1) myo-fibroblast markers and (2) glycolytic enzymes, under normoxic conditions. We validated the expression of these proteins in the fibroblastic stroma of human breast cancer tissues that lack stromal Cav-1. Importantly, a loss of stromal Cav-1 in human breast cancers is associated with tumor recurrence, metastasis, and poor clinical outcome. Thus, an absence of stromal Cav-1 may be a biomarker for the "Reverse Warburg Effect," explaining its powerful predictive value.

  • CAFs serve as a metabolic source of nutrients for cancer cells by generating energy-rich metabolites such as ketones, lactate, and pyruvate that support mitochondrial oxidative phosphorylation in adjacent tumor cells.

    “In addition to structural remodeling, CAFs serve as metabolic source of nutrients for cancer cells. Tumor cells induce oxidative stress in adjacent fibroblasts, triggering the production of reactive oxygen species (ROS) [42,43,44]. This ROS burden initiates autophagic processes in fibroblasts, leading to the generation of energy-rich metabolites such as ketones, lactate, and pyruvate. These”
  • CAFs secrete lactate, which tumor cells use as a metabolic fuel by incorporating it into oxidative phosphorylation in mitochondria, supporting high proliferation rates (the reverse Warburg effect).

    “Moreover, CAFs reportedly secrete lactate, which tumor cells can use as a metabolic fuel by incorporating it into oxidative phosphorylation (OXPHOS) in the mitochondria, thereby supporting their high proliferation rates. This phenomenon is known as the “reverse Warburg effect”.270”

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.
