Clearance of Senescent Cells Reverses the Peripheral Neuropathy Caused by Chemotherapy
A primary goal of chemotherapy is to force cancerous cells into programmed cell death or cellular senescence. Cellular senescence is a state of growth arrest that should normally be triggered by exactly the sort of damage and dysfunction exhibited by cancer cells, but cancer is characterized by a mutation-induced ability to bypass those restrictions. Chemotherapy remains the primary approach to cancer therapy, but chemotherapeutic agents are still at best only marginally discriminating. Treating cancer with chemotherapy has always been a fine balance between harming the cancer and harming the patient. Even in the best of o...

We report that electrical stimulation (ES) stimulation of post-stroke aged rats led to an improved functional recovery of spatial long-term memory (T-maze), but not on the rotating pole or the inclined plane, both tests requiring complex sensorimotor skills. Surprisingly, ES had a detrimental effect on the asymmetric sensorimotor deficit. Histologically, there was a robust increase in the number of doublecortin-positive cells in the dentate gyrus and SVZ of the infarcted hemisphere and the presence of a considerable number of neurons expressing tubulin beta III in the infarcted area. Among the genes that were unique...

TREM2 Inhibition as a Potentially Broadly Effective Cancer Therapy
It remains the case that far too much of the extensively funded work on cancer therapies is only relevant to a tiny subset of cancers. This is no way to achieve success in the fight to control cancer: there is only so much funding, only so many researchers, and too many types of cancer for an incremental strategy to make earnest process over the next few decades. The important lines of research into cancer treatments are those that can in principle be applied to many (or preferably all) cancers, and that are in principle highly effective, such as inhibition of telomere lengthening. The ideal cancer therapy is one that can ...

In conclusion, metabolomics is a promising approach for the assessment of biological age and appears complementary to established epigenetic clocks. Sedentary Behavior Raises the Risk of Cancer Mortality https://www.fightaging.org/archives/2020/06/sedentary-behavior-raises-the-risk-of-cancer-mortality/ Living a sedentary lifestyle is known to be harmful to long term health, raising the risk of age-related disease and mortality. Researchers here show that a sedentary life specifically increases cancer mortality, and does so independently of other factors. This is one of many, many reasons to maintain a re...

Demonstrating a Senolytic Chimeric Antigen Receptor T Cell Therapy
Chimeric antigen receptor (CAR) T cell therapies target specific surface features on other cells by providing T cells with a way to recognize that feature - the CAR. T cells so equipped will selectively destroy other cells with the target surface feature. To produce a CAR T cell therapy, a patient's T cells are taken, genetically engineered to introduce the CAR, expanded, and then reintroduced. This is presently used as a form of cancer therapy. Given a surface feature sufficiently specific to senescent cells, CAR T cell immunotherapy can be turned into a senolytic treatment, however. Senescent cell accumulation is one of ...

The Immune Response to Tumors Changes with Age
The interaction between the immune system and tumor is meaningfully different in young and old individuals. The aging of the immune system makes near everything worse in health and physiology. It greatly affects risk of cancer, in the sense of determining whether pre-cancerous cells are eliminated before they can gain a foothold. It also affects the distribution of cancer types, for reasons that are not fully explored. Further, and as discussed here, it affects the efforts of the immune system to destroy an established tumor. Advanced age is strongly correlated with both increased cancer incidence and general immu...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

Advocating for Senolytics to Prevent Accelerated Aging Resulting from Cancer Treatment
Chemotherapy and radiotherapy remain the presently dominant forms of cancer treatment. Immunotherapies are making slow inroads, but remain a minority of all treatments. Both chemotherapy and radiotherapy kill cells and force cells into senescence, cancerous cells and otherwise. They are a balance struck between killing the cancer and killing healthy tissue, and are are not pleasant at all for the patient. Cancer survivors have a significantly reduced life expectancy, as large as that resulting from life-long smoking, and evidence strongly suggests that this is due to a significantly increased burden of>senescent cells left...

Predicting the Future by Listening to the Experts
Stephanie Kuku Hugh Harvey By STEPHANIE KUKU, MD and HUGH HARVEY, MBBS The ability to predict in healthcare is the utopia promised by every artificial intelligence for healthcare built, funded and tested in the last decade. Yet very few doctors, technologists, or investors would have imagined they would live to witness a pandemic of the scale we are currently experiencing. We are still getting our heads round the lives lost, the lives of the frontline workers at risk, the disruption and self-isolation, the less fortunate who will suffer the most, the companies in survival mode, and a battered global economy. ...

In conclusion, our study demonstrated that Nrf2 deficiency promoted the increasing trend of autophagy during aging in skeletal muscle. Nrf2 deficiency and increasing age may cause excessive autophagy in skeletal muscle, which can be a potential mechanism for the development of sarcopenia.

In conclusion, elevated brain amyloid was associated with family history and APOE ε4 allele but not with multiple other previously reported risk factors for AD. Elevated amyloid was associated with lower test performance results and increased reports of subtle recent declines in daily cognitive function. These results support the hypothesis that elevated amyloid represents an early stage in the Alzheimer's continuum.

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.
