Resveratrol may be clinically beneficial to people with Alzheimer's disease

Resveratrol, given to Alzheimer's patients, appears to restore the integrity of the blood-brain barrier, reducing the ability of harmful immune molecules secreted by immune cells to infiltrate from the body into brain tissues, say researchers at Georgetown University Medical Center.

Researchers devise method to identify functional contribution of SIRT6

The enzyme sirtuin 6, or SIRT6, serves many key biological functions in regulating genome stability, DNA repair, metabolism and longevity, but how its multiple enzyme activities relate to its various functions is poorly understood.

Novel combination therapy may help provide clinically successful treatment for AD

Resveratrol is a naturally occurring polyphenolic phytochemical produced in several plants, especially grapes skin and seeds. One epidemiological study reported a positive association between moderate red wine consumption and a low incidence of cardiovascular disease, known as the "French Paradox."

New discovery may help researchers tackle mitochondrial diseases and age-related diseases

Buck Institute faculty Judith Campisi, PhD, says age researchers need to stop thinking of cellular senescence, now accepted as an important driver of aging, as a single phenotype that stems from genotoxic stress. Research from her lab reveals that cellular senescence, a process whereby cells permanently lose the ability to divide, is also induced by signaling from dysfunctional mitochondria - and that the arrested cells secrete a distinctly different "stew" of biologically active factors in a process unrelated to the damaging free radicals that are created in mitochondria as part of oxygen metabolism.

BIDMC scientists discover new vitamin B3 pathway that regulates liver metabolism

Researchers at Beth Israel Deaconess Medical Center have identified a new vitamin B3 pathway that regulates liver metabolism. The discovery provides an opportunity to pursue the development of novel drug therapies to address obesity, type 2 diabetes and related metabolic diseases.

Gladstone researchers identify way to prevent MS development in mice

Scientists from the Gladstone Institutes have discovered a way to prevent the development of multiple sclerosis (MS) in mice. Using a drug that blocks the production of a certain type of immune cell linked to inflammation and autoimmunity, the researchers successfully protected against the onset of MS in an animal model of the disease.

Ancient natural compound can protect the heart from hypertrophy

A natural compound derived from the bark of the magnolia tree, can protect the heart from hypertrophy, a thickening of cardiac muscle often caused by chronic high blood pressure that can lead to heart failure, researchers report in the April 14 issue of the online journal Nature Communications.

Feast-or-famine diet may extend lifespan, improve age-related diseases

University of Florida Health researchers have found that putting people on a feast-or-famine diet may mimic some of the benefits of fasting, and that adding antioxidant supplements may counteract those benefits.

First human clinical study of ChromaDex's NIAGEN nicotinamide riboside meets primary endpoint

ChromaDex Corp. announced today that the initial results of the first human clinical study for the company's NIAGEN nicotinamide riboside (NR) has met its primary endpoint.

Inhibition of SIRT1 protein may hold promise for treatment of metastatic Ewing sarcoma

Researchers at the Bellvitge Biomedical Research Institute (IDIBELL), led by Oscar Martínez Tirado participated in an international study which suggests inhibition of Sirtuin1 (SIRT1) protein as a future treatment option for metastatic Ewing sarcoma. The results of the study were published in the journal Cancer Research.

Study: Green tea compound may activate a cycle that kills oral cancer cells

A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.

Researchers find way to prevent noise-induced hearing loss

Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein.

UAlberta researchers discover link between pulmonary hypertension, diabetes and cancer

A UAlberta team has discovered that a protein that plays a critical role in metabolism, the process by which the cell generates energy from foods, is important for the development of pulmonary hypertension, a deadly disease.

SIRT6 protein inhibits liver and colon cancers, but promotes skin cancer caused by ultraviolet light

A new study published in Cancer Research shows SIRT6—a protein known to inhibit the growth of liver and colon cancers—can promote the development of skin cancers by turning on an enzyme that increases inflammation, proliferation and survival of sun-damaged skin cells.

Study reveals new information about body clock's sway over metabolism

Much of the liver's metabolic function is governed by circadian rhythms - our own body clock - and UC Irvine researchers have now found two independent mechanisms by which this occurs.

Researchers discover new mechanism that distinguishes normal blood stem cells from blood cancers

Researchers at Dartmouth's Norris Cotton Cancer Center have published results from a study Cell Reports that discovers a new mechanism that distinguishes normal blood stem cells from blood cancers.

SIRT1 protein necessary for telomere elongation and genome integrity during cell reprogramming

Cell reprogramming converts specialised cells such as nerve cells or skin cells towards an embryonic stem cell state. This reversal in the evolutionary development of cells also requires a reversal in the biology of telomeres, the structures that protect the ends of chromosomes; whilst under normal conditions telomeres shorten over time, during cell reprogramming they follow the opposite strategy and increase in length.

Thorne Research launches NiaCel that supports endurance, energy and healthy aging

Thorne Research today announced the launch of NiaCel™, an innovative nutritional supplement that supports endurance, energy, and healthy aging.

Mitochondrial enzyme SIRT5 regulates proteins involved in metabolism

The Sirtuin family of protein deacylases has received considerable attention in recent years due to its links to longevity, diabetes, cancer, and metabolic regulation.

Buck Institute finds link between ApoE4 and anti-aging protein targeted by resveratrol in red wine

he major genetic risk factor for Alzheimer's disease (AD), present in about two-thirds of people who develop the disease, is ApoE4, the cholesterol-carrying protein that about a quarter of us are born with. But one of the unsolved mysteries of AD is how ApoE4 causes the risk for the incurable, neurodegenerative disease.
