Figure Lengend Snippet: Knockdown of Steap4 in cardiomyocytes partially rescued the fatal heart failure in TG mice. (A) Cumulative survival rates of TG mice in shCtrl group (n = 20) and sh Steap4 (n = 20) group were recorded. (B) Representative images of the heart. (C) Cardiac Slc40a1 , Steap4 , and Fth proteins were measured using western blot analysis, normalized to β-actin (n = 4). (D) Total iron levels in the heart and serum were measured (n = 4). (E) Long-axis M-mode echocardiogram images and its analysis (n = 8). (F) Cardiac Nppa , Nppb , Myh7 mRNA were measured using qPCR, normalized to β-actin (n = 4). (G) Masson trichrome staining images and quantification of fibrotic areas (n = 4). The data is presented as the mean value plus or minus the standard error of the mean. Statistical significance is denoted by *p < 0.05 and **p < 0.01.
Article Snippet: Ad-sh Slc40a1 and Ad-shCtrl were provided by GeneChem Technology (Shanghai, China), in the form of adenoviral vectors carrying shRNA- Slc40a1 .Protein expression was observed 48 hours after viral infection.
Techniques: Western Blot, Staining
