Abstrakt: Diabetes mellitus continues to be a menace, being one of the five major causes of death in the world. In this study, the common fruit fly, Drosophila melanogaster, a well-studied genetic model organism for understanding molecular mechanisms of human diseases, and Artocarpus camansi (breadnut), an underutilized fruit, was used. This study was aimed at investigating the antihyperglycemic potentials of Artocarpus camansi fruit in sucrose-induced diabetic Drosophila melanogaster. Phytochemical screening was carried out after the fruit has been pulverized and freeze-dried. Total phenol content and total flavonoid content were carried out in vitro on the aqueous extract of Artocarpus camansi, and the result obtained showed that its phenol content is low, and its flavonoid content increases at increasing concentrations. Alpha-amylase inhibitory activity was carried out in vivo on sucrose-induced diabetic Drosophila melanogaster tissue. Gene expression profiling of Insulin-like peptide-2 (ILP-2), Insulin-like receptor (InR) and Ecdysone inducible gene L2 (Imp-L2) was carried out on trizol homogenate of Drosophila melanogaster tissue. In this study, Drosophila melanogaster was divided into nine groups. Group1 served as the basal control as they were fed with normal basal diet, group II served as the negative control which were fed with basal diet and 0.5 mL sucrose/100 mL distilled water, group III served as the positive control which were fed with basal diet 0.5 mL sucrose/100 mL distilled water and metformin, groups IV and V which were fed with basal diet and 0.1 and 1% Artocarpus camansi respectively, groups VI and VII were fed with basal diet, sucrose and 0.1 and 1% Artocarpus camansi respectively, groups VIII and IX served the purpose of the synergistic effect which were fed with basal diet, sucrose, metformin and 0.1 and 1% Artocarpus camansi respectively. All the groups were left for seven days. The experiment was conducted for 3 months and the fruit fly meals were changed every 5 days. Gene expression profiling results showed that the dietary inclusion of fruit downregulated the expression of ILP-2 and InR and upregulated the expression of Imp-L2 when the diabetic group were compared with the normal control. The results suggest that Artocarpus camansi fruit could possess antihyperglycemic properties and its use as a nutraceutical in the alleviation of diabetes should be encouraged.
