Stimulation of cultured colon 26 cells with TNF-alpha promotes lung metastasis through the extracellular signal-regulated kinase pathway.

abstract：:Diet is one of the elements that may influence the development of lung cancer. To ascertain the relationship between meat and fish consumption and the appearance of this disease, a case-control study was conducted on a population in Galicia (NW Spain), with a sample of 295 cases and 322 controls. All cases had histolo...
