Gene changes linked to severe repetitive behaviors

Graybiel lab identifies genes linked to abnormal repetitive behaviors often seen in models of addiction and schizophrenia. Extreme repetitive behaviors such as hand-flapping, body-rocking, skin-picking, and sniffing are common to a number of brain disorders including autism, schizophrenia, Huntington’s disease, and drug addiction. These behaviors, termed stereotypies, are also apparent in animal models […]

How human cells coordinate the start of DNA replication

Cold Spring Harbor Laboratory (CSHL) President and CEO Bruce Stillman have been dissecting DNA replication, a critical step in cell division, since the 1980s. His lab studies how Origin Recognition Complexes—ORCs—coordinate DNA duplication. They discovered how our cells assemble and disassemble ORCs during the cell division cycle. One ORC protein is sequestered […]

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 […]

BMI1, a promising gene to protect against Alzheimer's disease

Another step towards understanding Alzheimer's disease has been taken at the Maisonneuve-Rosemont Hospital Research Centre. Molecular biologist  Gilbert Bernier, and professor of neurosciences at Université de Montréal, has discovered a new function for the BMI1 gene, which is known to inhibit brain ageing. The results of his work have just been […]

Zika virus helps destroy deadly brain cancer in mice

The Zika virus that ravaged the Americas, leaving many babies with permanent brain damage, may have a silver lining. The virus can activate immune cells to destroy an aggressive brain cancer in mice, giving a powerful boost to an immunotherapy drug and sparking long-lasting immunological memory that can ward off […]

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 […]

Two servings of fish per week helps prevent recurrent heart disease

An analysis of several large studies involving participants from more than 60 countries, spearheaded by researchers from McMaster University, has found that eating oily fish regularly can help prevent cardiovascular disease (CVD) in high-risk individuals, such as those who already have heart disease or stroke. The critical ingredient is omega-3 […]

Probiotics increase gut bacteria diversity in extremely preterm infants

Extremely preterm infants can suffer from a life-threatening inflammation of the gut. A new clinical study has shown that supplements of a lactic acid bacterium may have positive effects by increasing the diversity of intestinal bacteria in these infants. The study has been published in the scientific journal Cell Reports […]

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 […]
