Cathepsin D: A possible biochemical marker for anthracycline cardiomyopathy

1987

This study was carried out in an attempt to assess the pattern of cathepsin D variations induced by Doxorubicin (DXR) and to clarify the role possibly played by this endopeptidase in the onset of anthracyclines-induced cardiotoxicity. We evaluated the variations in both total and 'sedimentable' enzyme activity of cathepsin D in the heart of mice treated once a week for up to 8 weeks with DXR (4 mg/kg i.v.b.wt.) and sacrificed 12h, 3 and 6 days after 1, 4, 5 and 8 administrations. Our results show that significant but transitory changes in both total and sedimentable activity of cathepsin D occur after each administration and decline after prolonged treatments. These data do not suggest, but…
