Most of us would probably think of smoking or air pollution when it comes to lung cancer risk, but researchers have discovered an intriguing link between the disease and the quality of our diets.

The researchers, from the University of Florida and the University of Kentucky, found that the molecule glycogen, which stores the simple sugar glucose, could potentially act as a driver of some types of lung cancer.

Glycogen was found at higher levels in human tissue samples of lung adenocarcinoma, the type responsible for 40 percent of lung cancers worldwide. In tests on mice, the team found that more glycogen helped lung cancers to grow faster, while taking the molecule away led to restricted tumor growth.

A large study of ADHD medications reveals small increases in blood pressure and heart rate. Despite concerns, these changes are generally not clinically significant. The findings suggest that cardiovascular monitoring is still important.

Hong & colleagues found that PPARd expression in endothelial cells is essential to maintain pulmonary vascular barrier integrity upon injury.

A new, AI-powered test can detect the molecular “fingerprints” of cancer in a patient’s blood using flashes of infrared light.

I-motif DNA structures are thought to form in cytosine-rich regions of the genome and to have regulatory functions; however, in vivo evidence for the existence of such structures has so far remained elusive. Now an engineered antibody that is selective for i-motif structures has been developed and used to detect i-motifs in the nuclei of human cells.
