Gut research yields new anti-cancer approach

...bitors do not bind to the standard tubulin-binding site that renders Taxol useless when binding sites change shapes thanks to ongoing genetic mutations. With standard anti-microtubule not an option for colorectal cancer, current chemotherapy regimens feature 5-fluorouracil (5-FU) in combination with ...

In obesity, brain becomes 'unaware' of fat

...brain’s hypothalamus, known as the ARH, is a major site of leptin sensing, harboring neurons that control appetite. More than 60 percent of American adults are now overweight or obese, and obesity prevalence in both adults and children is growing dramatically. When scientists first discovered leptin, i...

Scientists find genes involved in the battle between Hessian flies and wheat

"The focus of our work is to try to understand how the insect overcomes plant resistance and use that basic knowledge to enhance the durability of wheat against Hessian fly attack by combining several ge...
