Medical Xpress / Uncontrolled scarring: Study reveals the cell sensor that turns healing into harm

Fibrosis is the body's way of patching up damage—a bit like fixing a pothole. When skin is cut or a muscle is injured, fibroblast cells rush in to make fibronectin and collagen, which are two major extracellular matrix proteins ...

Phys.org / DNA-binding protein blocks virulence cascade in a diarrhea pathogen outside hosts, study finds

Some pathogens use temperature as a trigger and activate virulence only after entering the warmer environment of a host. A research team from Ruhr University Bochum, Germany, and the University of Münster, Germany, investigated ...

Medical Xpress / How pancreatic tumors thwart an iron-driven demise

Tumors driven by cancer-driving KRAS mutations are often susceptible to ferroptosis, a type of cell death that can be harnessed for cancer therapy. Given that more than 95% of pancreatic ductal adenocarcinomas (PDACs) harbor ...
