Should you take fish oil? Depends on your genotype

Fish oil supplements are a billion-dollar industry built on a foundation of purported, but not proven, health benefits. Now, new research from a team led by a University of Georgia scientist indicates that taking fish oil only provides health benefits if you have the right genetic makeup. The study, led by Kaixiong Ye […]

Higher Cardiovascular Health Score Correlates with Lower Epigenetic Age Acceleration

Epigenetic age acceleration is the degree to which epigenetic age is higher than chronological age. Epigenetic age is assessed via one of the epigenetic clocks, measuring the status of DNA methylation at numerous CpG sites on the genome. Some changes in DNA methylation patterns are characteristic of aging, a reaction […]

Evolution drives autism and other conditions to occur much more frequently in boys and men

Evolutionary forces drive a glaring gender imbalance in the occurrence of many health conditions, including autism, a team of genetics researchers has concluded. The human genome has evolved to favour the inheritance of very different characteristics in males and females, which in turn makes men more vulnerable to a host […]

Epidemiological Evidence for Herpesvirus Infection to Increase the Risk of Alzheimer's Disease

There is much debate these days over the contribution of persistent infection (such as by herpesviruses) to the development of Alzheimer's disease. Not everyone with the evident risk factors, such as obesity, frailty, chronic inflammation, and so forth, progresses from mild cognitive impairment to full blown Alzheimer's disease. Why is […]

Fourth generation of e-cigarettes is not harmless

A University of California, Riverside, study analyzing fourth-generation electronic cigarette, or EC, pod atomizer design features have found the pod atomizers are similar to those of previous generations and contain elements that may adversely affect health and accumulate in the environment. EC atomizers are chambers that hold nicotine-containing fluid and […]

Penn, CHOP and Yale Researchers’ Molecular Simulations Uncover How Kinase Mutations Lead to Cancer Progression

Kinases are a class of enzymes that are responsible for transferring the main chemical energy source used by the body’s cells. As such, they play important roles in diverse cellular processes, including signalling, differentiation, proliferation and metabolism. But since they are so ubiquitous, mutated versions of kinases are frequently found […]

The Binarized Transcriptomic Aging Clock

Patterns of epigenetic regulation of gene expression (and thus RNA and protein levels) change constantly in response to cell state and environment. Some of those changes are characteristic responses to the damage and dysfunction of aging. Since the demonstration of the first epigenetic clocks, those that predict age based on […]

Vaccination by inhalation

Many viruses infect their hosts through mucosal surfaces such as the lining of the respiratory tract. MIT researchers have now developed a vaccination strategy that can create an army of T cells that are ready and waiting at those surfaces, offering a quicker response to viral invaders. The researchers showed […]

New technology ‘retrains’ cells to repair damaged brain tissue in mice after stroke

Most stroke victims don’t receive treatment fast enough to prevent brain damage. Scientists at Ohio State University have developed technology to “retrain” cells to help repair damaged brain tissue – an advancement that may someday help patients regain speech, cognition and motor function, even when administered days after an ischemic […]

Age-Associated B Cells Contribute to Autoimmunity and Chronic Inflammation

The immune system becomes disordered and dysfunctional with age in numerous different ways. The B cell component accumulates inflammatory and problematic cells that are known as age-associated B cells. Here, researchers show that these errant B cells produce antibodies that provoke autoimmunity. B cell aging is a problem with a […]

FOXO1 Influences Proteosomal Function via Regulation of the Expression of a Proteasome Subunit

The proteasome is a complex structure in the cell that is responsible for breaking down unwanted proteins. Like other recycling processes, proteasomal function is connected to life span in short-lived species. Better cell maintenance in response to stress and damage improves cell function, organ function, and longevity. The proteasome is […]
