Expression of epidermal growth factor receptors in human lung tumors

D L Hwang et al. Cancer. .

Abstract

Using the adjacent histologically normal tissues obtained from the same patients as controls, six human lung tumors were studied for the activities of epidermal growth factor (EGF) receptor binding, and receptor autophosphorylation. There was a 1.2- to 2.8-fold increase in EGF receptor activities in lung tumors due to an increase in the number of receptors without changes in their affinity. The increase had no direct correlation with the degree of differentiation or the type of lung tumors. The elevated expression of EGF receptor may be one of the characteristics in lung tumors. Epidermal growth factor and its receptor also may play a role in the regulatory mechanisms during tumorigenesis.
