WebSpecifically, the allosteric regulation of phosphofructokinase regulates the emergence of glycolytic oscillations, which determines the rate of the glycolysis occurring (1). Additionally, a glycolytic enzyme like phosphofructokinase can favor cancer cell proliferation through nonmetabolic function. WebApr 14, 2024 · The YY1-RBM14 axis is involved in glycolysis of lung cancer. The malignant proliferation of tumor cells depends on the energy supply of glycolysis. We then explored the function of the YY1-RBM14 axis on glycolysis. YY1 overexpression increased glucose consumption, lactate production, and ECAR in PC9 and A549 cells (Fig. 6A–D). However, …
