to evaluate if there is any consistent relationship between the expression of intermediate filament proteins ( ifp ) , particularly keratins , and the degree of malignancy of prostatic cancer cells , a series of nine dunning rat prostatic cancer sublines that span the entire spectrum of progression of prostatic cancer were studied immunocytochemically by the use of a variety of antibodies specific for keratins , vimentin , or desmin .
