A Relative proteasomal activities in heart samples with or without OSTN overexpression (n = 6). B Representative western blot images and statistical results (n = 6). C Representative immunofluorescence images of Ub-positive protein aggregates in diabetic hearts with or without OSTN overexpression (n = 6). D Relative mRNA levels related to endoplasmic reticulum stress in diabetic hearts (n = 6). E Representative western blot images and statistical results (n = 6). F Caspase3 activity in heart samples (n = 6). G, H Statistical data of the TUNEL-positive nuclei and collagen deposition (n = 6). I Cardiac functional parameters (n = 8). Data represent mean ± SD. *P < 0.05 versus the matched group, NS indicates no significance.
