In contrast, stimulation of the “alternative” axis of the renin‐angiotensin system, involving ACE2, angiotensin‐(1‐7) (Ang‐(1‐7)) and the mitochondrial assembly receptor protected against cancer‐induced muscle wasting [S46] and improved motor performance and muscle co‐ordination in a 6‐hydroxydopamine rat model of PD.65 This evidence concerns the gene ACE2 and Parkinson disease.
