Lactate Inhibits Tumor Growth in Mice

Publishing in Nature, scientists have found that sodium lactate boosts the T cell-mediated anti-cancer immune response, leading to significant inhibition of tumor growth [1]. A double-edged sword As a means

Zero-Calorie Sweeteners Alter the Human Microbiome

A new open-label, randomized, controlled study published in Cell showed that zero-calorie sweeteners are metabolically active and some might impair glycemic response in healthy adults [1]. What does “sugar-free” mean?

NAD+ Ameliorates Age-Related Hearing Loss in Mice

In a preprint published in bioRxiv, scientists have shown that long-term supplementation of nicotinamide riboside (NR), a NAD+ precursor, alleviates the progression of age-related hearing loss in a mouse model

Guinea pig injection

Intravenous Stem Cells Alleviate Guinea Pig Osteoarthritis

Scientists have shown that intravenous delivery of mesenchymal stem cells, which has some advantages over the more conventional intra-articular injection, alleviates age-related osteoarthritis and decreases inflammation in guinea pigs [1].

New Hallmarks

Researchers Propose Five New Hallmarks of Aging

Publishing in Aging five months after their panel discussion in Copenhagen, many well-known researchers have explained their reasons for wishing to add new hallmarks of aging to the existing paradigm.

Atherosclerosis

Mitochondrial Drug Alleviates Atherosclerosis in Mice

Scientists have drastically improved various symptoms of atherosclerosis in mice by precisely targeting mitochondria with a plant-derived antioxidant [1]. Age-related and deadly Atherosclerosis, the accumulation of plaques on arterial walls,

Varied diet

Ketogenic and Mediterranean Diets Effective Against Diabetes

Pitting a ketogenic diet against a Mediterranean diet in pre-diabetes and Type 2 diabetes patients, scientists have learned that both confer metabolic benefits, but “keto” also has a darker side [1]. Diabetes is often reversible with diet While many anti-diabetes drugs have been developed in recent

Lactate Inhibits Tumor Growth in Mice

Publishing in Nature, scientists have found that sodium lactate boosts the T cell-mediated anti-cancer immune response, leading to significant inhibition of tumor growth [1]. A double-edged sword As a means of energy production, the Krebs cycle is preferred by most cells in most conditions. However, there

Skin fibroblast

Senescence-Associated Protein Promotes Skin Aging in Mice

Researchers publishing in Aging have identified an individual protein, secreted frizzled-related protein 4 (SFRP4), that is produced by senescent cells and contributes to skin aging in mice. The spread of the SASP The authors of this paper introduce this topic with a familiar discussion of the

Young and old mice

Brief Rapamycin Treatment in Early Adulthood Combats Aging

A study published in Nature Aging has shown that short-term rapamycin treatment in early adulthood extends lifespan in flies and improves gut health in both flies and mice [1]. A well-studied drug Rapamycin, an inhibitor of mTOR signaling, is capable of extending the lifespan of several

Mitochondrial Division Promotes Muscle Regeneration

A paper published in Cell Stem Cell has detailed how mitochondrial division is critical to the ability of muscle stem cells to regenerate damaged tissue [1]. Waiting until needed This paper begins with a discussion of quiescent muscle stem cells, which are held in reserve until

Umbilical Cord

Umbilical Plasma Injections Reduce Biological Age in Humans

Researchers have found that intramuscular injections of plasma concentrate made from human umbilical cord blood improve various health biomarkers and decrease biological age in elderly people [1]. Old blood, young blood Circulating proteins have a significant impact on our health, and blood plasma transfusion is increasingly

Lab mice

Canagliflozin Alleviates Several Aging Pathologies in Mice

Scientists have found that canagliflozin, an anti-diabetes drug that is known to extend lifespan in mice, alleviates an array of age-related pathologies, albeit in males only [1]. Anti-diabetes and anti-aging Canagliflozin, a widely used anti-diabetes drug, belongs to the class of sodium glucose cotransporter 2 (SGLT2)

Two Small Molecules May Provide Partial Reprogramming

A preprint published in bioRxiv has detailed how partial reprogramming through two small molecules can rejuvenate human cells as well as C.elegans, a common model of aging. Beyond OSKM This paper begins with a discussion of the four well-known Yamanaka reprogramming factors (OSKM) that cause cells

Zero-Calorie Sweeteners Alter the Human Microbiome

A new open-label, randomized, controlled study published in Cell showed that zero-calorie sweeteners are metabolically active and some might impair glycemic response in healthy adults [1]. What does “sugar-free” mean? The human brain is the main consumer of glucose in the body, and glucose availability is
