Melatonin reduces lung injury in type 1 diabetic mice by the modulation of autophagy.

BACKGROUND

In recent years, the role of autophagy has been highlighted in the pathogenesis of diabetes and inflammatory lung diseases. In this study, using a diabetic model of mice, we investigated the expression of autophagy-related genes in the lung tissues following melatonin administration.

RESULTS

Data showed histopathological remodeling in lung tissues of the D group coincided with an elevated level of IL-6, Becline-1, LC3, and P62 compared to the control group (p < 0.05). After melatonin treatment, histopathological remodeling was improved D + Mel group. In addition, expression levels of IL-6, Becline-1, LC3, and P62 were decreased in D + Mel compared to D group (P < 0.05). Statistically significant differences were not obtained between Mel group and C group (p > 0.05).

CONCLUSION

Our results showed that melatonin injection can be effective in the amelioration of lung injury in diabetic mice presumably by modulating autophagy-related genes.
