Deficiency of tumor suppressor Merlin facilitates metabolic adaptation by co-operative engagement of SMAD-Hippo signaling in breast cancer.

abstract：:Measurement of carcinogen DNA adducts in blood has been used as a surrogate for the target lung tissue. We aimed to examine whether genetic polymorphisms in several metabolic pathway genes modify the relation between DNA adducts in target lung and blood. One hundred and thirty-five early-stage lung cancer patients fro...
