New mechanism operates specific protein in brain to bring delay in aging

Among scientists, the role of proteins called sirtuins in enhancing longevity has been hotly debated, driven by contradictory results from many different scientists. But new research at Washington University School of Medicine in St. Louis may settle the dispute.

Study may lead to personalized treatments for mitochondrial energy disorders

Researchers have identified a master network of signaling molecules that acts like a "fuse box" to regulate the cellular effects of defective energy flow in mitochondrial respiratory chain diseases—a diverse set of difficult-to-treat genetic-based energy disorders.

Novel SIRT2 inhibitor protects against neuronal damage in animal models of Huntington's

Treatment with a novel agent that inhibits the activity of SIRT2, an enzyme that regulates many important cellular functions, reduced neurological damage, slowed the loss of motor function and extended survival in two animal models of Huntington's disease.

Modifying fat intake during pregnancy benefits children regardless of mother's size

If you are overweight and pregnant, your baby isn't destined to a life of obesity after all, according to a new research report published online in The FASEB Journal. In the report, a team of U.S. scientists show that modifying fat intake during pregnancy to a moderate level is enough to benefit the child regardless of the mother's size.

Mechanism provides beneficial characteristics of energy-burning brown fat to white fat

Columbia University Medical Center (CUMC) researchers have identified a mechanism that can give energy-storing white fat some of the beneficial characteristics of energy-burning brown fat. The findings, based on studies of mice and of human fat tissue, could lead to new strategies for treating obesity and type 2 diabetes.

Cornell grants ChromaDex worldwide rights to novel manufacturing process for nicotinamide riboside

ChromaDex Corp. today announced that Cornell University has granted the natural products company ChromaDex exclusive worldwide rights to a novel manufacturing process for nicotinamide riboside (NR).

Lack or loss of SIRT3 protein induces proliferation of breast cancer cells

Research published in the Cancer Cell journal in March was a significant step in knowing the causes of cancer better, especially breast cancer, revealing that the lack or loss of a protein in the cells known as SIRT3, induces the proliferation of this disease and thereby, this protein can be an may be a therapeutic target in the development of effective therapies for cancer. The research was led by Dra. Marcia Haigis of the Harvard Medical School, with the participation of Dr. Arkaitz Carracedo, from the Proteomics Laboratory at CIC bioGUNE.

Aging-associated protein deficiency may lead to positive breast cancer in women

The most common type of breast cancer in older women - estrogen and progesterone receptor positive breast cancer - has been linked to a protein that fends off aging-related cellular damage.

Lack of SIRT1 protein exhibits impaired memory and learning: Study

A protein implicated in many biological processes also may play a role in memory, according to a study led by the University of Southern California and the National Institute on Aging at the National Institutes of Health.The findings, published this week in the Journal of Neuroscience, agree with research by a different team published online by Nature on July 11. Both studies found that mice lacking the protein SIRT1 exhibited impaired memory and learning, suggesting SIRT1's importance to those functions.
