Kids who experience severe stress are more likely to develop a host of physical and mental health problems by the time they reach adulthood, including anxiety, depression and mood disorders. But how does early life stress put children at risk when they grow up? To find out, researchers from the […]

The lungs are made up of some 30 to 40 different types of cells. “When you get sick, these cells can change. New cells can come in and resident cells can change over,” says Naftali Kaminski, MD, Boehringer Ingelheim Pharmaceuticals, Inc., Endowed Professor of Medicine (Pulmonary), and chief of the […]

Two-thirds of the 5.5 million Americans with Alzheimer’s disease are women, and without effective prevention and treatments, that number will triple by 2050. Now, thanks to an innovative partnership, two UCI researchers have been awarded $100,000 to dig into why such a huge gender disparity exists. Sunil Gandhi and Mathew […]

Yale researchers have tested a new method for directly measuring synaptic loss in individuals with Alzheimer’s disease. The method, which uses PET imaging technology to scan for a specific protein in the brain linked to synapses, has the potential to accelerate research for new Alzheimer’s treatments, the researchers said. The […]

Researchers have identified a key protein involved in the irregular brain cell activity seen in autism spectrum disorders and epilepsy. The protein, p53, is well-known in cancer biology as a tumor suppressor. The findings, reported in the journal Human Molecular Genetics and Neuropharmacology, will open new avenues for understanding the […]

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells that move blood around the body. A new discovery in how heart […]

Studying two rare inherited cancer syndromes, Yale Cancer Center (YCC) scientists have found the cancers are driven by a breakdown in how cells repair their DNA. The discovery, published in Nature Genetics, suggests a promising strategy for treatment with drugs recently approved for other forms of cancer, said the researchers. The two conditions […]

Prostate cancer is the third most common cause of cancer-related deaths in the UK, and researchers from Cardiff University have identified a genetic alteration that is linked to poor prognosis for patients with the disease. Advanced prostate cancer patients initially respond well to hormonal therapies but nearly all will eventually […]

A new molecule designed by University of Adelaide researchers shows great promise for future treatment of many cancers. The new molecule successfully targets a protein that plays a major role in the growth of most cancers. This protein target is called proliferating cell nuclear antigen (PCNA), otherwise known as the […]

The sex of a baby controls the level of small molecules known as metabolites in the pregnant mother’s blood, which may explain why risks of some diseases in pregnancy vary depending whether the mother is carrying a boy or a girl, according to new research from the University of Cambridge. […]

A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer’s growth and spread, University of Illinois researchers report in a new study in mice. The molecules, called endocannabinoids, are made naturally by the body and have similar properties to cannabinoids found in marijuana – but […]

Recent studies show that 40 percent of Americans over the age of 85 have Alzheimer's disease, and that the disease begins 10 to 20 years before people show up at the doctor's office with memory problems. One major problem with understanding Alzheimer’s is not being able to clearly see why […]
