Study reveals missing link in mechanisms underlying fight-or-flight response

We’ve all felt the effects of an adrenaline rush. Faced with danger, real or perceived, the heart beats faster, breathing quickens and muscles tighten as the body prepares to fight a threat or flee from it. The role of adrenaline in triggering the fight-or-flight response is one of the most well-studied phenomena in biology. However, the precise molecular mechanisms for […]

Mechanisms help pancreatic cancer cells avert starvation

A new study reveals the mechanism that helps pancreatic cancer cells avoid starvation within dense tumors by hijacking a process that pulls nutrients in from their surroundings. Led by researchers at NYU Grossman School of Medicine, the study explains how changes in the gene RAS—known to encourage the abnormal growth seen in 90 percent of pancreatic cancer patients—also accelerate a […]

Researchers study the mechanisms behind learning and long-term memory in the brain

When we first purchase a smart phone, all of our settings and applications are the same. But as time passes, everyone’s phones will change drastically as we adapt them to our own individual needs and preferences. In the same way, our memories and life experiences are loaded into our brains, making one person unique from another. Even the simplest experiences […]

Elucidation of central mechanisms of salt-induced hypertension through activation of sympathetic nerve activities

Hypertension is a major risk factor for cardiovascular disease worldwide, and approximately 40 percent (1 billion) of adults aged 25 and above have been diagnosed with hypertension (World Health Organization 2013; ref. 1). A positive correlation between salt (NaCl) intake and blood pressure (BP) has long been postulated. A battery of studies has shown that a diet high in salt […]
