Lkb1 loss promotes tumor progression of BRAF(V600E)-induced lung adenomas.

Abstract excerpt

Aberrant activation of MAP kinase signaling pathway and loss of tumor suppressor LKB1 have been implicated in lung cancer development and progression. Although oncogenic KRAS mutations are frequent, BRAF mutations (BRAF(V600E)) are found in 3% of human non-small cell lung cancers. Contrary to KRAS mutant tumors, BRAF(V600E)-induced tumors are benign adenomas that fail to progess. Interestingly, loss of tumor...
