This high glucose level could be a symptom of the increased uptake of glucose and the activation of the glycolysis pathway as part of the Warburg effect, since it is known that cancer cells increase the uptake of glucose to generate glycolytic intermediates required for the synthesis of carbohydrates, fatty acids, and proteins, and to increase ATP production, as it has been observed after the exposure to Ag@MSNs-Tf (Fig. 1) [30, 31]. This evidence concerns the gene TF and cancer.
