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.

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. To confirm this, fasted mice were chloroquine-treated, which prevents autophagosome/ lysosome fusion and favors LC3-II accumulation. Whereas LC3-II accrued in young C57BL/6, we found no increase in the aged C57BL/6 or in young or old BALB/c. Thus, the aged can mount an acute response, albeit with reduced flux. 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. 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.

Mechanisms for post-maturation oocyte aging PMOA are not fully understood, and whether autophagy plays any role in PMOA is unknown. To explore the role of autophagy in PMOA, expression of. The LC3-II/I ratio reflects the conversion of the protein from the cytosolic form to the autophagosome associated form upon autophagy activation and was also calculated and showed significant increases for both bafilomycin and chloroquine treatments, although chloroquine was statistically further increased, albeit modestly, from bafilomycin. Cardiovascular diseases are the most prominent maladies in aging societies. Indeed, aging promotes the structural and functional declines of both the heart and the blood circulation system.
