the role of the pinosome-lysosome pathway in the degradation of 125i-labelled bovine insulin by cultured human fibroblasts was examined by comparing the effects of various known inhibitors of pinocytosis and lysosomal degradation on the uptake and degradation of 125i-labelled polyvinylpyrrolidone , formaldehyde-denatured bovine serum albumin and bovine insulin by these cells .
