Gastric cancer fueled by ‘crosstalk’ between nerves and cancer cells

Blocking nerve growth factor receptor disrupted cholinergic signaling and prevented stomach cancer growth in mice Gastric tumors are started by specialized cells in the stomach that signal nerves to make more acetylcholine, according to a study in mice. The multinational team of researchers who conducted the study also identified a substance called nerve growth factor that stimulates nerve development and, ...

Blood pressure medication paves the way for approaches to managing Barrett’s syndrome

New ways of using mechanisms behind certain blood pressure medications may in the future spare some patient groups both discomfort and lifelong concern over cancer of the esophagus. This, in any case, is the goal of several studies of patients with Barrett’s syndrome at Sahlgrenska Academy. “If we could filter out those who are not at greater risk, it would ...

UCLA researchers combat antimicrobial resistance using smartphones

A simple, inexpensive attachment could help to expand testing to regions with limited resources A team of UCLA researchers has developed an automated diagnostic test reader for antimicrobial resistance using a smartphone. The technology could lead to routine testing for antimicrobial susceptibility in areas with limited resources. Antimicrobial-resistant bacteria are posing a severe threat to global public health. In particular, ...

Gene mutations among young patients with colorectal cancer

While many patients with colorectal are diagnosed when they are older than 50, about 10 percent of patients are diagnosed at younger ages. So what is the frequency of cancer susceptibility gene mutations among patients with colorectal cancer who are diagnosed younger than 50? A new study published online by JAMA Oncology by Heather Hampel, M.S., C.G.C., of the Ohio State University ...

New gene fusions and mutations linked to gastrointestinal stromal tumors

Findings could lead to additional targeted treatments for more patients In recent years, researchers have identified specific gene mutations linked to gastrointestinal stromal tumors (GIST), which primarily occur in the stomach or small intestine, with 5,000 to 6,000 new cases per year in the United States. But 10 to 15 percent of adult GIST cases and most pediatric cases lack ...
