Mitochondrial Bioenergetics and Healthy Aging
The importance of mitochondria in essential biological functions cannot be understated. The Molina Lab focuses on understanding how mitochondrial function is related to aging and the development of age-related diseases.
Blood-Based Biomarkers of Aging
Reliable biomarkers of human biological aging have not yet been established. We are proposing that bioenergetic profiles of blood cells are related to multiple age-related diseases and disorders. Further, we are investigating blood-borne circulating factor(s) that may be responsible for mediating changes in systemic bioenergetic capacity.
Bioenergetics and Cognitive Decline
There is increasing evidence suggesting that mitochondrial dysfunction plays an important role in the pathogenesis of Alzheimer’s Disease (AD) and dementia. We are interested in identifying multi-parameter bioenergetic signatures that are associated with presymptomatic stages of AD and are predictive of AD progression.
Aging and Physical Function
A central goal of our research is to understand the mechanisms underlying the decline of physical function with aging and age-related conditions, such as heart failure and obesity. We are investigating the relationship between bioenergetic decline due to alterations in mitochondrial quality control and age-related exercise intolerance.
Wellcome Leap Dynamic Resilience
The National Institute of Aging convened a workshop to discuss how to improve measures that predict and assess resilience. Among the primary recommendations from the meeting was to expand the use of data and biospecimens from existing epidemiological studies identifying long-term predictors of health outcomes. We propose to utilize the UC San Diego Rancho Bernardo Study (RBS), one of the longest running population-based observational cohorts in existence.
