Clones of Tumor Cells Derived from a Single Primary Human Lung Tumor Reveal Different Patterns of β 1 Integrin Expression

Abstract excerpt

Previously we reported that over 75% of human non-small cell lung cancers overexpress the beta 1 integrin VLA-2 on their surface and show an increase in the mRNA encoding the alpha-2 chain of this integrin. These results suggested the possibility that the overproduction and overexpression of one or more of the beta 1 integrin may be involved in the pathogenesis of human lung tumors by modulating the invasive...
