In humans, the LKB1 gene is located on the short arm of chromosome 19, which is frequently deleted in lung tumors. Unlike most cancers of sporadic origin, in non-small cell lung cancer (NSCLC) nearly half of the tumors harbor somatic and homozygous inactivating mutations in LKB1. In NSCLC, LKB1 inactivation strongly predominates in adenocarcinomas from smokers and coexists with mutations at other important cancer genes, including KRAS and TP53. Remarkably, LKB1 alterations frequently occur… CONTINUE READING
