Vitamin D on Impact of Blue Light on Glucose Metabolism in D. Melanogaster

Overview

Type 2 Diabetes (T2D) is a metabolic disorder characterized by impaired insulin secretion, leading to hyperglycemia. Prolonged exposure to artificial sources of blue light has been shown to negatively impact glucose metabolism by increasing insulin resistance. The impact of blue light exposure on glucose levels in the model organism Drosophila melanogaster was first confirmed through an initial phase of the experiment. Vitamin D supplementation is known to help regulate blood sugar levels, and therefore, in a subsequent phase of the experiment, it was used in conjunction with the blue light treatment to investigate the combination effect on glucose levels. Three vials of fruit flies, treated with vitamin D, were exposed to blue light for seven days, and their hemolymph was collected and tested using a pediatric TB needle and a standard glucose monitor. The analysis revealed a negative correlation (positive impact) between vitamin D concentration and glucose levels, indicating that vitamin D can be used as a supplement to counteract the impact of environmental conditions such as blue light exposure. This study highlights the potential of metabolic approaches, such as vitamin D supplementation, in managing T2D and the need for further research in this area.
