Johns Hopkins and University of Alberta researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, they say, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.

Complex Interactions Between Proteins Rbm38 and p53 Govern Tumor Suppression, Aging

Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging. The study was published online in the journal PNAS Dec. 15.

Both positive and negative experiences influence how genetic variants affect the brain and thereby behaviour, according to a new study. “Evidence is accumulating to show that the effects of variants of many genes that are common in the population depend on environmental factors. Further, these genetic variants affect each other,” explained Sheilagh Hodgins of the University of Montreal and its affiliated Institut Universitaire en Santé Mentale de Montréal.

Short Sleep Duration and Sleep-Related Breathing Problems Increase Obesity Risk in Kids

Sleep-related breathing problems and chronic lack of sleep may each double the risk of a child becoming obese by age 15, according to new research from Albert Einstein College of Medicine of Yeshiva University. The good news is that both sleep problems can be corrected. The study, which followed nearly 2,000 children for 15 years, published online today in The Journal of Pediatrics.

Brain Inflammation a Hallmark of Autism, Large-Scale Analysis Shows

Brain_map_NIGMS_web.jpg

While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains.
