Abstract

There is considerable evidence supporting the involvement of acidic lysosomal proteases in the catabolic processes associated with developmental programs. I examined levels of catD activity in cell and media fractions prepared from developmental and pathological cell culture model systems. In prefusion myoblasts, this activity eluted at 34 kDa, a molecular mass consistent with the fully processed double chain form of the protease. In fused myoblasts, a second peak of activity appeared consistent with the less processed, single chain form of catD. Unlike myogenesis, the progression of lowly metastatic MCF-7 breast cancer cells to highly metastatic, adriamycin-resistant ones was accompanied by a decrease in catD activity.
