Recombinant Human Growth Hormone Inhibits Lipotoxicity, Oxidative Stress, and Apoptosis in a Mouse Model of Diabetic Cardiomyopathy

Figure 6

rhGH treatment decreased apoptosis in db/db mice. (a) TUNEL-stained (green fluorescence) and DAPI-stained (blue fluorescence) photomicrographs. (b) Cardiac BAX, Bcl-2, cleaved caspase-3, and t-caspase-3 levels were measured by western blotting. (c) Relative protein expression was quantified. (d) Representative immunohistochemistry for BAX, Bcl-2, and cleaved caspase-3 in the cardiac tissues. (e) Positive expression was quantified. Scale bar: 100 μm. The arrows indicate positively stained cells. per group. vs. db/db+rhGH group, ^& vs. db/db group, and ^# vs. db/db group.
