ABSTRACT
Abstract

Background:

Diabetes mellitus (DM) is one of the major risk factors for cardiovascular disease, leading to endothelial dysfunction and angiogenesis impairment . MiR-126 and miR-210 support angiogenic response in endothelial cells.

Objective:

The present study sought to explore the effect of garlic and voluntary exercise, alone or together, on miR-126 and miR-210 expressions and cardiac angiogenesis in rats with type 1 diabetes.

Methods:

Male Wistar rats were divided into five groups (n = 7) Control, Diabetes, Diabetes+Garlic, Diabetes+Exercise, and Diabetes+Garlic+Exercise. Diabetes was induced in the animals by streptozotocin (ip, 50 mg/kg). The rats were then fed raw fresh garlic homogenate (250 mg/kg) or were subjected to voluntary exercise, or to combined garlic and voluntary exercise for 6 weeks. MiR-126 and miR-210 expressions in the myocardium were determined by real time PCR, and the serum lipid profile was measured by enzymatic kits. Angiogenesis was evaluated by immunostaining for PECAM-1/ CD31 in the myocardium.

Results:

Diabetes reduced both cardiac miR-126 expression and angiogenesis (p < 0.05). On the other hand, there was a miR-210 expression increase in the myocardium of diabetic animals (p < 0.001). However, those effects reversed either with garlic or voluntary exercise (p < 0.01). Moreover, treating diabetic rats with garlic and voluntary exercise combined had an additional effect on the expressions of miR-126 and miR-210 (p < 0.001). Furthermore, both voluntary exercise and garlic significantly improved serum lipid profiles (p < 0.001).

Conclusion:

The induction of diabetes decreased angiogenesis in the myocardium, whereas our treatment using long-term voluntary exercise and garlic improved myocardial angiogenesis. These changes were possibly owing to the enhancement of myocardial miR-126 and miR-210 expressions.
RESUMO
Resumo Fundamento O diabetes mellitus (DM) é um dos principais fatores de risco para doenças cardiovasculares, levando à disfunção endotelial e inibição da angiogênese. O miRNA-126 e o miRNA-210 promovem a resposta angiogênica em células endoteliais.

Objetivo:

O presente estudo buscou explorar o efeito do alho e de exercícios físicos voluntários, isoladamente ou em conjunto, nas expressões do miRNA-126 e do miR-210 e na angiogênese cardíaca em ratos com diabetes tipo 1.

Métodos:

Ratos Wistar machos foram divididos em cinco grupos (n = 7) Controle, Diabetes, Diabetes+Alho, Diabetes+Exercícios e Diabetes+Alho+Exercícios. Introduziu-se diabetes nos animais por estreptozotocina (ip, 50 mg/kg). Os ratos foram então alimentados com homogenato de alho fresco cru (250 mg/kg), ou foram submetidos a exercícios voluntários, ou a uma combinação de alho e exercícios voluntários, durante 6 semanas. As expressões do miRNA-126 e do miRNA-210 no miocárdio foram determinadas por PCR em tempo real, e o perfil lipídico sérico foi medido por kits enzimáticos. A angiogênese foi avaliada por imunocoloração por PECAM-1/CD31 no miocárdio

Resultados:

O diabetes reduziu a expressão do miRNA-126 cardíaco e da angiogênese (p < 0,05). Por outro lado, houve um aumento da expressão do miRNA-210 no miocárdio dos animais diabéticos (p < 0,001). No entanto, tais efeitos foram revertidos com alho ou exercícios voluntários (p < 0,01). Além disso, o tratamento de ratos diabéticos conjuntamente com alho e exercícios voluntários teve um efeito adicional sobre as expressões do miRNA-126 e do miRNA-210 (p < 0,001). Além disso, tanto os exercícios voluntários quanto o alho melhoraram significativamente os perfis lipídicos séricos (p < 0,001).

Conclusões:

A indução de diabetes diminuiu a angiogênese no miocárdio, enquanto nosso tratamento com exercícios voluntários de longa duração e alho melhorou a angiogênese miocárdica. Estas alterações devem-se, possivelmente, ao aumento das expressões do miRNA-126 e do miRNA no miocárdio.
