Abstract
SIGNIFICANCE
Chronic Non-Communicable Diseases (NCDs) are the leading causes of disability and death worldwide. NCDs mainly comprise diabetes mellitus, cardiovascular diseases, chronic obstructive pulmonary disease (COPD), cancer, and neurological degenerative diseases, which kill more than 80% of population, especially elderlies, worldwide. Recent Advances: Several recent theories established NCDs as multifactorial diseases, where a combination of genetic, epigenetic and environmental factors contributes to their pathogenesis. Nevertheless, recent findings suggest as the common factor linking all these pathologies is an increase in oxidative stress and the age-related loss of the antioxidant mechanisms of defense against it. Impairment in mitochondrial homeostasis with consequent deregulation in oxidative stress balance, has also been suggested.

CRITICAL ISSUES
Therefore, antioxidant proteins deserve particular attention for their potential role against NCDs. In particular, Peroxiredoxin6 (Prdx6) is a unique antioxidant enzyme, belonging to Peroxiredoxins (Prdxs) family, with double properties, peroxidase and phospholipase activities. Through these activities, Prdx6 has been shown to be a powerful antioxidant enzyme, implicated in the pathogenesis of different NCDs. Recently, we described a phenotype of diabetes mellitus in Prdx6 knockout mice, suggesting a pivotal role of Prdx6 in the pathogenesis of cardio-metabolic diseases.

FUTURE DIRECTIONS
Increasing awareness on the role of antioxidant defenses in the pathogenesis of NCDs may open novel therapeutic approaches to reduce the burden of this pandemic phenomenon. However, the knowledge on the role of Prdx6 in the NCDs prevention and pathogenesis is still not clarified.
