Researchers find pathways that uncover insight into development of lung cancer

(Dartmouth-Hitchcock Medical Center) Lung cancer results from effects of smoking along with multiple genetic components. A new study conducted at Dartmouth identifies two main pathways for the role of chromosome 15q25.1--a leader in increasing susceptibility to lung cancer--in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung...
