| Summary: | Dysregulation of calcium signaling is a hallmark of diabetes mellitus (DM) and grain amaranth (AG) has antidiabetic properties. Information on the mechanism of action of AG on blood, renal, and hepatic tissues is sparse, although it continues to be an important alternative medicinal plant in several developing countries. The objective of the study was to determine key changes in calcium levels and s100a1 protein levels and antioxidant and histopathologic changes in blood, renal, and hepatic tissues of male diabetic Wistar rats. Materials and Methods. This was an experimental study in which 30 male Wistar rats were kept for
5 weeks (6 groups, N =5). Groups 1-IV had T2DM induced using Nicotinamide and Streptozotocin: Group I, Mixtard ; group
II, positive control; group III, 25% AG; group IV, 50% AG. Furthermore, group V consisted of normal rats given 50% GA and
group VI was negative control. Blood, renal, and hepatic tissues were collected and analyzed for calcium, s100a1 protein levels, and
antioxidant and histopathological changes. Results andDiscussion. Inblood, renal, andhepatic tissue, calciumand s100a1 levelswere
low during T2DMand these increased following AG supplementation.This was important for improved metabolic processes, thus
leading to the lowmalondialdehyde (MDA) and glutathione peroxidase (GPx) activity in the tissues. Efficient antioxidant status was important for improved calciumsignaling mechanisms, thus leading to improved tissue function and protection demonstrating the importance of AG as an alternativemedicinal source through the calciumsignaling pathway. Conclusion. Grain amaranth exerts its antidiabetic properties through improved calcium homeostasis in blood, kidney, and liver. |
