Increased fibronectin mRNA in alveolar macrophages following in vivo hyperoxia.

abstract：:The matrix glycoprotein, fibronectin, stimulates the proliferation of non-small cell lung carcinoma in vitro through α5β1 integrin receptor-mediated signals. However, the true role of fibronectin and its receptor in lung carcinogenesis in vivo remains unclear. To test this, we generated mouse Lewis lung carcinoma cell...
