A Mouse Model of Chemotherapy-Related Cognitive Impairments Integrating the Risk Factors of Aging and APOE4 Genotype.

This study demonstrates cognitive impairments in aged APOE4 knock-in mice after doxorubicin treatment and establishes this system as a novel and powerful model of CRCI. PMID: 32027870 [PubMed - as supplied by publisher]

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

This study, for the first time, shows that transplantation of non-autologous mitochondria from healthy skeletal muscle cells into normal cardiomyocytes leads to short-term improvement of bioenergetics indicating "supercharged" state. However, over time these improved effects disappear, which suggests transplantation of mitochondria may have a potential application in settings where there is an acute stress.

Researchers here provide evidence for natural killer cells to act to reduce inflammation in the brain. This is of interest because chronic inflammation in brain tissue, neuroinflammation, is a prominent feature of neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. If a natural mechanism that suppresses inflammation can be harnessed, it might be possible to slow or reverse neurodegenerative conditions, given that inflammation appears to play such a significant role in their progression. That said, recent work on cellular senescence in the supporting cells of brain suggests that selectively elimi...

We report a new class of natural-product-inspired covalent inhibitors of telomerase that target the catalytic active site. Age-Related Epigenetic Changes that Suppress Mitochondrial Function https://www.fightaging.org/archives/2020/03/age-related-epigenetic-changes-that-suppress-mitochondrial-function/ Today's open access research reports on two specific epigenetic changes observed in old individuals that act to reduce mitochondrial function. This joins an existing list of genes for which expression changes are known to impact mitochondrial function with age. A herd of hundreds of mitochondria are found ...

You may have already heard the term “insulin resistance,” as it has been widely discussed by doctors and the media. But did you know that you can reduce or reverse it in the vast majority of people? Insulin resistance, i.e., the inability of the body’s cells, especially liver, muscle, and brain, to respond to insulin and allow blood sugar to enter cells, drives numerous abnormal health conditions including type 2 diabetes, hypertension, coronary heart disease, fatty liver, Alzheimer’s dementia, and cancer. It is therefore a driving force behind so many modern and common chronic health conditions. Yo...

In this study, we intravenously administrated the young mitochondria into aged mice to evaluate whether energy production increase in aged tissues or age-related behaviors improved after the mitochondrial transplantation. The results showed that heterozygous mitochondrial DNA of both aged and young mouse coexisted in tissues of aged mice after mitochondrial administration, and meanwhile, ATP content in tissues increased while reactive oxygen species (ROS) level reduced. Besides, the mitotherapy significantly improved cognitive and motor performance of aged mice. Our study, at the first report in aged animals, not only prov...

The Methuselah Foundation is one of the oldest of the present generation of organizations focused on advancing human rejuvenation, founded more than 15 years ago. At that time there was none of the present enthusiasm for treating aging as a medical condition, and indeed the concept was mocked outside the scientific community and actively discouraged within research circles by leading scientists in the field of gerontology. The Methuselah Foundation and its network of allies are a large part of the reason why things have changed: it took a great deal of work to change this dismissive culture into one that saw and embraced t...

In conclusion, the recently demonstrated protective effects of NMN treatment on neurovascular function can be attributed to multifaceted sirtuin-mediated anti-aging changes in the neurovascular transcriptome. Our present findings taken together with the results of recent studies using mitochondria-targeted interventions suggest that mitochondrial rejuvenation is a critical mechanism to restore neurovascular health and improve cerebral blood flow in aging.
