It's not all genetic: Common epigenetic problem doubles cancer risk in mice

... "In the mice, loss of imprinting of IGF2 roughly doubles the risk that the genetic mutation will cause a tumor," says postdoctoral fellow Atsushi Kaneda, Ph.D. "Double the risk may not seem like much, but this loss of imprinting is common." The researchers' mice mirror two situations in people because the...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...ship, where simply doubling the amount of clathrin doubles the speed at which vesicles are shuttled back and forth," Dr. Ryan explained. "Instead, it's what biochemists call a highly 'cooperative' relationship. That means that at a certain moment in this relationship some kind of 'tipping point' occurs, so t...

Pair of cancer genes found to drive both cell migration and division

...s. When a normal cell prepares to divide, it first doubles its genetic material, and then creates a "furrow" down the middle, cutting the cell in half. The research team noticed that the two halves of a normal dividing cell looked and acted like two cells moving away from each other. "Essentially, the two h...

Depression gene may weaken mood-regulating circuit

... shown that inheriting the short variant more than doubles risk of depression following life stresses,** boosts amygdala activity while viewing scary faces,*** and has been linked to anxious temperament. Yet, how it works at the level of brain circuitry remained a mystery. The NIMH research team first scann...

Researchers identify new genes that regulate aging

...creases lifespan. For example, the worm's lifespan doubles when one gene is prohibited from working properly, and inhibition of another gene increases the length of life by 20%. The genes discovered affect a wide variety of activities, including insulin signaling, metabolism, and dietary regulation. Genes i...

Minimal genome should be twice the size, study shows

...lternative pathways into the minimal genome almost doubles its size." The researchers have developed a way of predicting bacterial genome content using two bacteria that have evolved from E.coli. Buchnera and Wigglesworthia live inside insects in a symbiotic relationship where they provide essential molec...

Horseshoe crab decline threatens shorebird species

...g their Delaware Bay stopover, the red knot nearly doubles its body mass as it gorges itself almost exclusively on horseshoe crab eggs. The purpose of this feeding frenzy is to ensure that the shorebirds have enough energy to complete the trip north to their breeding ground in the Artic. However, due to ho...

Study shows interruption of antiretroviral therapy increases risk of disease and death

...y of interrupting antiretroviral therapy more than doubles the risk of AIDS or death from any cause. Researchers affiliated with the Mailman School of Public Health and Harlem Hospital Hospital led a large multi-center international study, known as Strategies for Management of Anti-Retroviral Therapies, or S...

Genomic comparison of lactic acid bacteria published

... "In a heroic effort, their publication more than doubles the number of lactic acid bacterial genomes that are publicly available and provides the research community with a wealth of high-quality data that can be used to understand and improve starter cultures for dairy, meat, and wine fermentations; probio...

Study finds surfing safer than soccer

...ise to most surfers that the injury rate more than doubles when surfing in larger surf (overhead) compared to smaller waves, as the energy of waves increases as it grows in height. In addition, a sea floor with a sandy bottom is much more forgiving upon impact than one covered with reefs or rocks," says Nath...

Risk of stroke doubles if diagnosed with Type 2 diabetes
