Defects in Critical Gene Lead to Accelerated Lung Tumor Growth, University of North Carolina Study

CHAPEL HILL – Cancer causing mutations occur in our bodies every day – but luckily, we have specific genes that recognize these malignant events and keep cells from growing out of control. Only a few of these genes – called tumor suppressors – are currently known. Now scientists at the University of North Carolina at Chapel Hill School of Medicine and Harvard Medical School have added to the list another powerful tumor suppressor, a gene called LKB1. Their research indicates that this gene is mutated in almost a quarter of all human lung cancers. In mice, these mutations result in tumors that are more aggressive and more likely to spread throughout the body.
