Sera from cancer patients specifically suppressed phosphofructokinase (fructose-6-phosphate kinase [PFK], EC 2.7.1.11), a rate-limiting enzyme in the glycolysis pathway. Among 418 cancerous sera, 68.7% evidence suppression; there was no organ specificity. Among 42 sera from early gastric cancer
PFKFB3 was overexpressed in gastric cancer patients and promoted the proliferation and migration of gastric cancer cells.

OBJECTIVE
Gastric cancer is one of the most common cancers worldwide, and the prognosis is still very poor due to the lack of specific and sensitive biomarkers. Aerobic glycolysis is one of the critical hallmarks of gastric cancer cells, and several glycolytic enzymes are highly expressed in gastric

The Warburg effect is an emerging hallmark of cancer, which has the tumor suppressor p53 as its major regulator. Herein, we unveiled that p53 activation by (S)-tryptophanol-derived oxazoloisoindolinone (SLMP53-1) mediated the reprograming of glucose metabolism in cancer cells and xenograft
Androgens enhance the glycolytic metabolism and lactate export in prostate cancer cells by modulating the expression of GLUT1, GLUT3, PFK, LDH and MCT4 genes.

OBJECTIVE
The present study aims to investigate the role of androgens in controlling the glycolytic metabolism and lactate efflux in prostate cancer (PCa) cells.
METHODS
Androgen-responsive LNCaP cells were treated with 5α-dihydrotestosterone (DHT, 10 nM) for 12-48 h, and their glycolytic

Kinetic properties of phosphofructokinase 2 (PFK2) and regulation of glycolysis by phorbol 12-myristate 13-acetate (PMA) and insulin were investigated in highly glycolytic HT29 colon cancer cells. PFK2 was found to be inhibited by citrate and, to a lesser extent, by phosphoenolpyruvate and ADP, but
Oleanolic acid reduces aerobic glycolysis-associated proliferation by inhibiting yes-associated protein in gastric cancer cells.

Gastric cancer represents a common malignancy of digestive tract with high incidence and mortality. Increasing evidence suggests that the growth of gastric tumor cells relies largely on aerobic glycolysis. Currently, many potential anti-cancer candidates are derived from natural products. Here, we
In vitro and in vivo study of epigallocatechin-3-gallate-induced apoptosis in aerobic glycolytic hepatocellular carcinoma cells involving inhibition of phosphofructokinase activity.

Glycolysis, as an altered cancer cell-intrinsic metabolism, is an essential hallmark of cancer. Phosphofructokinase (PFK) is a metabolic sensor in the glycolytic pathway, and restricting the substrate availability for this enzyme has been researched extensively as a target for chemotherapy. In the

It is essential to life that a balance is maintained between processes that produce ATP and those that consume it. An obvious way to do this would be to have systems that monitor the levels of ATP and ADP, although because of the adenylate kinase reaction (2ADP↔ATP+AMP), AMP is actually a more
An extract from wax apple (Syzygium samarangense (Blume) Merrill and Perry) effects glycogenesis and glycolysis pathways in tumor necrosis factor-α-treated FL83B mouse hepatocytes.

FL83B mouse hepatocytes were treated with tumor necrosis factor-α (TNF-α) to induce insulin resistance to investigate the effect of a wax apple aqueous extract (WAE) in insulin-resistant mouse hepatocytes. The uptake of 2-[N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl)amino]-2-deoxyglucose (2 NBDG), a

The increased glucose metabolism in cancer cells is required to fulfill their high energetic and biosynthetic demands. Changes in the metabolic activity of cancer cells are caused by the activation of oncogenes or loss of tumor suppressors. They can also be part of the metabolic adaptations to the

Pancreatic cancer is a complex disease, in need of new therapeutic approaches. In this study, we explored the effect and mechanism of action of epigallocatechin-3-gallate (EGCG), a major polyphenol in green tea, alone and in combination with current chemotherapeutics on pancreatic cancer cell
Low glucose enhanced metformin's inhibitory effect on pancreatic cancer cells by suppressing glycolysis and inducing energy stress via up-regulation of miR-210-5p

To explore mechanisms underlying the discrepancy in anti-tumor effects of metformin on pancreatic cancer cells PANC-1 under different glucose conditions. We cultured PANC-1 cells in 25 mM and 5 mM glucose media, then treated with or without metformin. It showed that metformin significantly inhibited

Chloroacetaldehyde (CAA), a product of hepatic metabolism of the widely used anticancer drug ifosfamide (IFO), has been reported to decrease cancer cell proliferation. The basis of this effect is not completely known but has been attributed to a drop of cellular ATP content. Given the importance of
