Overexpression of tumor necrosis factor-alpha diminishes pulmonary fibrosis induced by bleomycin or transforming growth factor-beta.

abstract：:It had been thought that the central molecular event in the malignant transformation of a cell is the mutation of certain oncogenes-and the resultant dysregulated activation of their encoded proteins. During the past decade, however, it has become clear that alteration of the activity of the protein products of tumor ...
