Lactate dehydrogenase (LDH) is a key enzyme involved in the process of glycolysis, assisting cancer cells to take glucose and generate lactate, as well suppress evade...
Background: Both mitochondrial dysfunction and aerobic glycolysis are signs of growing aggressive cancer. If altered metabolism of cancer cell is intended, using the glycolysis inhibitor (2-deoxyglucose (2DG)) would be a viable therapeutic method. The AMP-activated protein kinase (AMPK), as a metabolic sensor, could be activated with metformin and it can also launch a p53-dependent metabolic ch...
Glioblastomas rely mainly on aerobic glycolysis to sustain proliferation and growth; however, little is known about the regulatory mechanisms of metabolism in glioblastoma stem cells. We show that miR-143 is significantly down-regulated in glioma tissues and glioblastoma stem-like cells (GSLCs), while miR-143 over-expression inhibits glycolysis by directly targeting hexokinase 2, and promotes d...
One of the most common abnormalities of cancer cells is their predilection to engage in a high rate of glycolysis despite the continued availability of oxygen. First described by Otto Warburg, this phenomenon of aerobic glycolysis (or the Warburg effect) has recently been proposed to result from cancer-associated alterations in signal transduction pathways. In this issue of The EMBO Journal, Pa...
We present a model of osmoadaptation in S. cerevisiae based on existing experimental and theoretical work. In order to investigate the impact of osmoadaptation on glycolysis, this model focuses on the interactions between glycolysis and osmoadaptation, namely the production of glycerol and its influence on flux towards pyruvate. Evaluation of this model shows that, depending on initial relation...
Reprogramming of cellular metabolism is a hallmark of cancers. Cancer cells more readily use glycolysis, an inefficient metabolic pathway for energy metabolism, even when sufficient oxygen is available. This reliance on aerobic glycolysis is called the Warburg effect, and promotes tumorigenesis and malignancy progression. The mechanisms of the glycolytic shift in tumors are not fully understood...
The metabolism of rat retina was found to be sensitive to the concentration of the carbon dioxide-bicarbonate buffer system. Increasing the carbon dioxide from 1 per cent to 5 per cent at constant pH nearly doubled both respiration and glycolysis. Increasing the carbon dioxide at constant pH from 5 per cent to 20 per cent had no effect on glycolysis, but depressed the Q(O(O2) ) from 31 to 19. I...
Studies on the rate-limiting factors of glycolysis in Ehrlich ascites tumor cells have indicated that orthophosphate is the major rate-limiting factor for glycolysis (l-5). Pi presumably influences the rate of glyceraldehyde 3-phosphate dehydrogenase, the only glycolytic enzyme known to require Pi. However, recent reports have indicated that Pi may have other important effects on glycolytic sys...
Cancer cell proliferation is a metabolically demanding process, requiring high glycolysis, which is known as "Warburg effect," to support anabolic growth. Steroid receptor coactivator-3 (SRC-3), a steroid receptor coactivator, is overexpressed and/or amplified in multiple cancer types, including non-steroid targeted cancers, such as urinary bladder cancer (UBC). However, whether SRC-3 regulates...
