The reviewers begin this paper by discussing various chronic and age-related diseases associated with mitochondrial dysfunction, including proteostasis-related diseases such as Alzheimer’s [1] and Parkinson’s [2], sarcopenia [3], cardiovascular disease [4], and even cancer [5] and obesity [6].
While there are drugs to alter mitochondrial function, these reviewers note a lack of therapies other than exercise that can affect fundamental mitochondrial maintenance processes, such as fusion, fission, and autophagy. In an effort to find such a therapy, these researchers have investigated the effects of resveratrol, a natural compound that has frequently been investigated as having potential use against the processes of aging.
Neurological diseases
Previous research has found that in Alzheimer’s disease, mitochondria supply less ATP to the neurons and exhibit signs of genetic damage [7]. However, one study has found that by using specially engineered nanoparticles, it is possible to direct resveratrol directly to the neurons, and this approach has had success in rodent models [8]. Orally administered resveratrol has also had success in enhancing signaling for removing damaged mitochondria (mitophagy) in Alzheimer’s disease models [9].
The compound has also had success in Parkinson’s disease models. In a rat model, resveratrol nanoparticles reduced Parkinson’s-like symptoms and ameliorates mitochondrial dysfunction [10]. Another study expanded upon the pathway involved, noting how resveratrol improved mitochondrial health and decreased cellular death in another model [11].
Cardiovascular diseases
This review also cites multiple papers reporting that resveratrol may be effective in treating both acute and chronic cardiovascular diseases. One paper suggests that resveratrol may help in recovery from ischemic stroke by reducing hydrogen peroxide [12]. Another paper has reported that resveratrol decreases the cellular death caused by oxidized low-density lipoprotein [13]. In another model of stroke, resveratrol was reported to protect both neurons and heart cells from death [14].
Many teams of researchers have reported that resveratrol may be effective in decreasing oxidative stress, thus keeping vascular tissue healthier for longer. One paper reported that resveratrol both increases the formation of mitochondria and decreases oxidative stress through the SIRT1 pathway [15]. The SIRT1 pathway is also involved in resveratrol’s potential protective effects against fat accumulation and obesity [16].
Age-related frailty disorders
Resveratrol may also be effective in the treatment of arthritis. According to one study, resveratrol’s positive effects on mitochondria lead to an reduction in damage to chondrocytes, the cells responsible for building cartilage [17]. Another study found that cells that encouraged arthritis symptoms had a lower survival rate when exposed to resveratrol [18].
The age-related muscle wasting known as sarcopenia has also been reported to be affected by resveratrol. Sirtuins are involved here as well, with their upregulation being accompanied by increased numbers of mitochondria, thus making more energy available for muscles [19]. However, in a human study, resveratrol supplementation needed to be combined with exercise to be effective against sarcopenia, suggesting a more complicated interaction [20].
Despite its various effects, however, resveratrol has never been proven to extend lifespan in people, and it does not appear to lengthen the lives of healthy mice. However, the data found in these studies remains valuable, and the basic mechanisms involved in resveratrol’s purported effects may be better targeted through resveratrol-containing nanoparticles or with other compounds or interventions that preserve mitochondrial function.
