Abstract

Background: Insulin resistance is a condition in which insulin cannot take up glucose, increasing blood glucose. Elderly people are more exposed to insulin resistance, requiring dietary interventions that extend longevity. Trehalose, a naturally occurring sugar, showed potentially reduce insulin resistance which can be measured using the HOMA-IR index. Objectives: This study aimed to assess HOMA-IR levels as a parameter of insulin resistance in old rats after giving trehalose sugar. Methods:  Experimental research with 28 male Wistar rats (Rattus novergicus) was separated into 4 groups, the control group of young rats (Group A), the control group of old rats (Group B), a group of old rats that were given 2% Trehalose solution (Group C), and a group of old rats that given 2% sucrose solution (Group D) that observed for 8 weeks. Results: The results showed differences in HOMA-IR levels (p<0.001) between old and young subjects. The intervention in Group C was optimal in reducing levels of HOMA-IR (p<0.001) by 18.2% compared with the old control, while Group D increased levels of HOMA-IR by 14.3% (p<0.001) compared with the old control. The age of the subjects with HOMA-IR level is positively correlated (p<0.001; r=0.721) and the weight of subjects with the HOMA-IR level is also positively correlated (p<0.001; r=0.698), indicating that the older and the greater weight of subject resulting in the bigger of HOMA-IR value. Conclusion: Trehalose is effective in reducing HOMA-IR levels as a parameter of insulin resistance in old rats.

Abstract

Background: Vascular inflammation is one of contributing factors to the pathogenesis of arterial aging. Age-related activation of the inflammatory process can lead to various macro-and microvascular pathologies. The pro-inflammatory microenvironment generated in the vascular wall can lead to the pathogenesis of vascular diseases due to an increase in vascular dysfunction. Trehalose is a disaccharide that has several functions, protecting against stressors (one of them is reactive oxygen species/ROS) and preventing the inflammatory responses induced by endotoxic shock. Objectives: To analyze the effect of trehalose supplementation on macrovascular inflammatory processes related to the aging process. Methods: The experimental study used 28 male Wistar rats (Rattus novergicus) which were divided into 4 groups, young control group (Group A), old control group (Group B), 2% sucrose group (Group C), and 2% trehalose group (Group D); were then observed for 8 weeks. Results: The results showed that there were no significant differences in aortic tissue NFκB-p65 expression between old and young subjects (p=0.247). The 2% trehalose group had 40% lower aortic tissue NFkB-p65 expression compared to the old control group (p=0.012); while the group given 2% sucrose solution had a 30% higher aortic tissue NFkB-p65 expression compared to the trehalose group (p=0.018). Conclusion: Trehalose has a good effect on aging-associated vascular inflammatory processes that can be seen from the low aortic tissue NFκB-p65 expression in old rats.
