One second, one life: this axiom was true when LEAF was founded, and it remains true today. More than one person a second dies from age-related diseases, not including contagious diseases that youthful immune health would likely have protected them from. Let’s see what progress has been made last month in helping people live longer.

Education

Exploring the Senescence-Associated Secretory Phenotype: Today, we want to highlight a recent review that charts the pro-inflammatory signals produced by senescent cells. The SASP contributes to the smoldering background of chronic inflammation that typically accompanies aging and can cause many problems.

Working in biotechWorking in Longevity with a Non-Traditional Background: The Program Director of the On Deck Longevity Biotech Fellowship gives us some examples of leaders and founders working on aging that came from “non-traditional” backgrounds.

What is Nicotinamide Riboside? A Summary of NR: Steve Hill explains nicotinamide riboside (NR), a part of the B3 vitamin family. Like other forms of vitamin B3, nicotinamide riboside gets converted into nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for life.

Research Roundup

Fasting clock5-Day Fast Improves Longevity Biomarkers in Humans: A recent study in Clinical and Translational Medicine followed people who went 5 days without eating and found improvements both immediately afterwards and up to 98 days later.

A Metabolic Peptide Improves Cognitive Performance in Mice: Cognitive decline and neurological aging may involve a peptide known as adropin, according to new research. The identification of this link offers a new perspective on the aging brain and points to novel potential therapies.

Gut brain inflammationFecal Transplantation for Alzheimer’s Disease: A recent review published in Cureus shows why fecal microbial transplantation (FMT) might be able to help sufferers of Alzheimer’s disease, showing how tightly the gut and brain are intertwined.

MTOR Inhibition Leads to 30% Life Extension in Progeric Mice: Researchers have created a new mouse model for studying Hutchinson-Gilford progeria syndrome (HGPS) and achieved 30% lifespan extension in these animals by genetically downregulating mTOR.

Muscles in motionBoosting NANOG to Revitalize Muscle Cell Progenitors: Boosting the expression of the transcription factor NANOG reduces markers of cellular senescence in cultured muscle cells and in live mouse models. This holds out the hope that cells could be rejuvenated without reprogramming them to pluripotency, avoiding some of the associated risks such as oncogenicity.

Key Source of Thymic Aging Discovered: Publishing in Nature Communications’ Cell Death Discovery, a team of Chinese researchers has discovered a reason for thymic involution, the age-related decline of the thymus. When thymic epithelial cells (TECs) are dysregulated and the function of the thymus falters, this can lead to both infection susceptibility and autoimmune disorders.

Elderly exercisingMoveAge: A New Movement-Based Biological Aging Clock: Researchers have developed a biological aging clock based on movement data from wearable devices. Using their clock and the same dataset, they identified a few possibly life-prolonging nutrients and drugs.

Understanding How We Evolved to Age: This review examines the appearance of the hallmarks in different groups across the tree of life, with the aim of providing a comprehensive picture of how the mechanisms of aging have evolved.

Bone structure fails as we age but can be rejuvenatedEpigenomic Rejuvenation for Restoring Bone Stem Cells: Researchers have shown that age-related loss of bone maintenance is caused by changes in gene expression. Perhaps most importantly, those changes can also be reversed and the bone marrow stem cells rejuvenated.

Senolytics Alleviate Spinal Disc Degeneration in Mice: A group of researchers has found that early long-term treatment of mice with the popular senolytic duo dasatinib and quercetin alleviates symptoms of intervertebral disc degeneration, a major age-related cause of disability.

ProteinGetting Proteins Right to Live Longer: Changing a single amino acid in a single protein boosts the fidelity of protein synthesis, and new research shows how that is enough to increase lifespan in a variety of organisms.

Our Brains’ Metabolism Changes as We Age: A study conducted in Sweden and published in Scientific Reports has outlined the relationship between aging and the metabolites present in cerebrospinal fluid (CSF), which cushions and supports the brain and spine.

ExerciseActivity and Diet Shown to Slow Aging (Again): Scientists have used DNA methylation markers to measure the anti-aging effects of healthy diet and physical activity, reaching interesting, if at times contradictory, results.

The Effects of Caloric Restriction on Stem Cells: A review published in The Malaysian Journal of Medical Sciences has outlined what effects caloric restriction (CR) has on the development and differentiation of stem cells.

Long LifespanStudy Suggests No Theoretical Limit on Human Lifespan: This study shows that mortality risk stops increasing past 110 years of age, so it may be possible, although unlikely, for a human to live 130 years or perhaps longer, even without a rejuvenative intervention.

Calorie intake rather than food quantity consumed is the key factor for the anti-aging effect of calorie restriction: The researchers illustrate the effects of caloric restriction and food quantity on lifespan extension along with the potential mechanisms of action.

Steps per Day and All-Cause Mortality in Middle-aged Adults in the Coronary Artery Risk Development in Young Adults Study: Men and women of African and Caucasian descent benefited from taking more than 7,000 steps per day.

Association of Walnut Consumption with Total and Cause-Specific Mortality and Life Expectancy in U.S. Adults: Higher walnut consumption was associated with a lower risk of total and CVD mortality and a greater gained life expectancy among U.S. elder adults.

Nicotinamide Riboside Improves Ataxia Scores and Immunoglobulin Levels in Ataxia Telangiectasia: Treatment with NR is tolerated well and associated with improvement in ataxia and serum immunoglobulin concentrations in patients with this disease.

Effect of resveratrol on C-reactive protein: An updated meta-analysis of randomized controlled trials: This meta-analysis demonstrates that resveratrol consumption is effective in lowering the levels of this inflammation-associated protein.

The Effects of Korean Red Ginseng on Biological Aging and Antioxidant Capacity in Postmenopausal Women: KRG significantly increased the mtDNA copy number and total antioxidant status while improving symptoms of fatigue in postmenopausal women.

Lithium can mildly increase health during ageing but not lifespan in mice: Lithium has a narrow therapeutic dose range, and overdosing can severely affect organ health. Within the tolerable dosing range, the researchers found some mildly positive effects of lithium on healthspan but not on lifespan.

DNA methylation age analysis of rapamycin in common marmosets: Overall, the epigenetic clocks developed here for the common marmoset are expected to be useful for age estimation of wild-born animals and for anti-aging studies in this species.

Surrounding Greenness and Biological Aging Based on DNA Methylation: A Twin and Family Study in Australia: Higher surrounding greenness (vegetation) was associated with slower biological aging, as indicated by GrimAge age acceleration, in Australian women.

The association between epigenetic clocks and physical functioning in older women: a three-year follow-up: While GrimAge performed the best, current epigenetic clocks do not provide strong benefits in predicting the decline of physical functioning, at least during a rather short follow-up period and restricted age-range.

Reversible reprogramming of cardiomyocytes to a fetal state drives heart regeneration in mice: Short-term OSKM expression before and during myocardial infarction ameliorates myocardial damage and improves cardiac function.

Cardiac radiotherapy induces electrical conduction reprogramming in the absence of transmural fibrosis: Collectively, this study provides evidence for radiation-induced reprogramming of cardiac conduction as a potential treatment strategy for arrhythmia management in VT patients.

A genome-engineered bioartificial implant for autoregulated anticytokine drug delivery: Therapeutic implants completely prevented increased pain sensitivity and bone erosions, a feat not achievable by current clinically available disease-modifying drugs.

Gut Microbiota Predicts Healthy Late-Life Aging in Male Mice: Using machine learning techniques, the researchers show that gut microbial signatures from 21-month-old mice can predict the healthy aging of 30-month-old mice with reasonable accuracy.

Hyperbaric oxygen therapy alleviates vascular dysfunction and amyloid burden in an Alzheimer’s disease mouse model and in elderly patients: This study demonstrates the efficacy of hyperbaric oxygen therapy in hypoxia-related neurological conditions, particularly in AD and aging.
