Protein tyrosine nitration in the ventilatory muscles: role of nitric oxide synthases.

abstract：:Transformation-related protein 63-expressing (p63(+)) basal cells are confined to the trachea in the mouse lung. However, after influenza virus infection or bleomycin treatment, patches of p63(+) cells were observed in the damaged lung parenchyma. To address whether the newly induced p63(+) cells are derived from the ...
