Curcumin-supplemented diets improve antioxidant enzymes and alter acetylcholinesterase genes expression level in Drosophila melanogaster model.

Curcumin, a bioactive polyphenolic compound in turmeric (Curcuma longa) rhizomes has been shown to exert anti-aging properties with limited scientific basis. Hence, this study sought to examine the antioxidant and anti-cholinesterase activities of curcumin-supplemented diets as well as their molecular effect on superoxide dismutase (SOD) and acetylcholinesterase (AChE) genes expression level associated with lifespan extension in Drosophila melanogaster model. In this experiment, D.
