In this study, we demonstrate that inefficient autophagy contributes to the development of atherosclerotic plaques in low-SS areas. Defective endothelial autophagy not only curbs endothelial alignment with the direction of blood flow, but also promotes an inflammatory, apoptotic, and senescent phenotype. Plaquenil cause constipation Hydroxychloroquin ra Hydroxychloroquine To better interpret changes in LC3, chloroquine was used to block the fusion of the autophagosome with the lysosome, and Figures 5g−i show that pretreatment with chloroquine could upregulate LC3. Trehalose administration to mice overexpressing GFP-tagged LC3 significantly increased the number of GFP-LC3 dots, both in the presence and absence of chloroquine administration. TRE also increased cardiac LC3-II levels after 4 weeks following myocardial infarction MI, indicating that it induced autophagy in the heart in vivo. Autophagy is commonly measured by western blotting for LC-II, in which it is generally accepted that an increase in LC3-II is associated with an increase in autophagy although increased LC3-II could also result from impaired autophagic flux. Studies of autophagy in the aging heart have yielded inconsistent results. Altogether, these findings underline the role of endothelial autophagic flux activation by SS as an atheroprotective mechanism. Furthermore, genetic inactivation of endothelial autophagy in a murine model of atherosclerosis increases plaque burden exclusively in high-SS areas that are normally resistant to atherosclerotic plaque development.

These results raise the exciting possibility that autophagy may play an important role in combating the adverse effects of aging in the heart. In this review, we discuss the role of autophagy in the heart during aging, how autophagy alleviates age-dependent changes in the heart, and how the level of autophagy in the aging heart can be restored. Intermittent fasting could prevent heart disease through the same mechanism. Autophagy declines with age. Aging is the number one correlate of increased risk for coronary heart disease atherosclerosis, and aging also correlates strongly with a decline in natural levels of autophagy. Atherosclerotic plaques tend to develop preferentially in areas of the vasculature exposed to low and disturbed shear stress SS, but the mechanisms are not fully understood. In this study, we demonstrate that inefficient autophagy contributes to the development of atherosclerotic plaques in low-SS areas. Defective endothelial autophagy not only curbs endothelial alignment with the direction.
