Research progress on the interaction between circadian clock and early vascular aging.

Area of Science:

• Chronobiology
• Vascular Biology
• Aging Research

Background:

• The circadian clock regulates organ rhythms and cellular aging, influencing gut flora, inflammation, and redox homeostasis.
• Circadian disruptions and sleep disorders are linked to premature vascular aging and chronic inflammation.
• The precise mechanisms connecting the circadian system and early vascular aging remain unclear.

Purpose of the Study:

• To explore the biphasic relationship between vascular aging and the circadian system.
• To summarize the links between the circadian clock and early vascular aging.
• To discuss the hypothesis that circadian rhythm deterioration exacerbates vascular aging and cardiovascular disease.

Main Methods:

• Literature review and synthesis of existing research.
• Analysis of the roles of inflammatory processes, oxidative stress, intestinal flora, and cellular senescence.
• Exploration of the link between circadian rhythm disruption and vascular aging.

Main Results:

• Circadian rhythms influence key biological processes implicated in vascular aging.
• Disruptions in circadian function are associated with accelerated vascular aging and inflammation.
• Four major pathways link the circadian system to early vascular aging: inflammation, oxidative stress, gut microbiota, and cellular senescence.

Conclusions:

• Deterioration of circadian rhythms may significantly exacerbate early vascular aging.
• This relationship offers potential for developing personalized chronotherapies for cardiovascular disease.
• Further research is needed to fully elucidate these mechanisms and therapeutic strategies.
