Article Abstract
Background/aim: The present study investigated the anticancer effects of intraperitoneally administered D-allose in in vivo models of head and neck cancer cell lines.
Materials And Methods: To assess the direct effects of D-allose, its dynamics in blood and tumor tissues were examined.
Results: D-allose was detected in blood and tumor tissues 10 min after its intraperitoneal administration and then gradually decreased. In vivo experiments revealed that radiation plus D-allose was more effective than either treatment alone. Thioredoxin-interacting protein (TXNIP) mRNA over-expression was detected after the addition of D-allose in in vitro and in vivo experiments. D-allose inhibited cell growth, which was associated with decreases in glycolysis and intracellular ATP levels and the prolonged activation of AMPK. The phosphorylation of p38-MAPK was also observed early after the administration of D-allose and was followed by the activation of AMPK and up-regulated expression of TXNIP in both in vitro and in vivo experiments.
Conclusion: Systemically administered D-allose appears to exert antitumor effects. Further studies are needed to clarify the appropriate dosage and timing of the administration of D-allose and its combination with other metabolic agents.

A major hallmark of cancer is the reprogramming of cellular metabolism from oxidative phosphorylation (OXPHOS) to glycolysis, a phenomenon known as the Warburg effect. To sustain high rates of glycolysis, cancer cells overexpress GLUT transporters and glycolytic enzymes, allowing for the enhanced uptake and consumption of glucose. The Warburg effect may be exploited in the treatment of cancer; certain epimers and derivatives of glucose can enter cancer cells and inhibit glycolytic enzymes, stunting metabolism and causing cell death.

Age-related physical and cognitive decline may be ameliorated by consuming functional foods. d-Allose, reported to have multiple health benefits, may temper aging phenotypes, particularly brain function. We investigated whether d-allose supplementation improves cognitive function.

Rare sugars, which exist only in very small quantities in nature, have recently attracted attention for their various biological functions in medicine. Among them, d-allose is known to have cytoprotective effects by antioxidant effects. In this study, we investigated whether the antioxidant effects of d-allose reduce brain edema in a water intoxication model of cytotoxic brain edema.

Background: Peritoneal dialysis (PD) is a crucial dialysis method for treating end-stage kidney disease. However, its use is restricted due to high glucose-induced peritoneal injury and hyperglycaemia, particularly in patients with diabetes mellitus. In this study, we investigated whether partially replacing d-glucose with the rare sugar d-allose could ameliorate peritoneal injury and hyperglycaemia induced by peritoneal dialysis fluid (PDF).
