How NAD+ Relates to Smell Loss with Age

Researchers publishing in Aging Cell have elucidated a relationship between aging, the loss of smell, and NAD+ in a mouse model. Olfactory ability declines with age Roughly half of people

Abstract DNA

Inhibiting DREAM for Enhanced DNA Damage Repair

In a new study published in Nature Structural and Molecular Biology, researchers have demonstrated that by manipulating the DREAM protein complex, a major regulator of DNA damage response, it might be possible to alter the number of DNA mutations accumulated with age [1]. Mutations and DREAMs

Vesicles from Senescent Cells Encourage Young Stem Cells

Scientists have shown that extracellular vesicles derived from senescent stem cells can improve the proliferation, viability, and migration capacity of healthy stem cells [1]. Cell-to-cell packages Extracellular vesicles (EVs, not to be confused with electric vehicles) are tiny membrane-bound bubbles that are emitted by cells and

Promoting Muscle Regeneration With an Immune Factor

A paper published today in Nature Aging has shown that a macrophage-regulating factor has a significant impact on muscle regeneration. Healing slows with aging The researchers note two key reasons for the decline of regenerative abilities with aging. The first is stem cell exhaustion, the gradual

Vital Muscle Enzyme Declines With Aging

Research published in Nature Metabolism has described PCYT2, an enzyme essential for muscle function, and how it declines with aging. A necessary lipid synthesizer in muscle Human beings need PCYT2 as part of the Kennedy pathway to synthesize two critical components of the phosopholipid membrane that

Global obesity

The Human Cost of Metabolic Diseases

A new paper published in Cell Metabolism has shown the growing influence of metabolic diseases in an aging population. Related diseases studied together Metabolic diseases include hypertension, type 2 diabetes, hyperlipidemia, obesity, and non-alcoholic fatty liver disease [1]. These diseases, representing fundamental problems with how the

Cholesterol

Inflammation Strongly Predicts Mortality After Statin Use

Analyzing data from three clinical trials, scientists have shown that excessive inflammation is a much stronger predictor of cardiovascular and all-cause mortality in patients on statins than excessive LDL cholesterol levels. These findings can upend the current standard of care for such patients [1]. The two

Damaged DNA

Mitochondria, DNA, and Oxidative Stress

A paper published in Experimental Gerontology has provided a fresh and detailed look at the effects of oxidative stress on longevity. Revisiting an old theory The free radical theory of aging, which purports that reactive oxygen species (ROS) are the core driver of aging, was developed

Depression

New Treatment Alleviates Depression Symptoms in Mice

Scientists have shown that the protein GDF11 can reverse depression-like symptoms in naturally aged mice and in a mouse model of depression. Depressed humans have lower GDF11 as well [1]. Depression and aging Severe mental disorders, including depression, have been linked to significantly shorter lifespans [2].

Young Blood Alters Gene Expression in Old Brain Cells

Research published today in Nature Aging has shown that heterochronic parabiosis, the circulatory joining of young and old organisms, has rejuvenative effects on the gene expression of multiple types of brain cells in mice. Parabiosis affects a wide variety of factors at once Heterochronic parabiosis is

Metformin and Rapamycin Rejuvenate Stem Cells in Mice

In a new study published in Aging Cell, researchers have shown that two promising anti-aging agents, the antibiotic rapamycin and the anti-diabetic drug metformin, reverse aging in a population of intestinal stem cells [1]. The aging intestine Older people are more prone to gastrointestinal problems [2].
