(D) To quantify fibrosis, transversal sections of total muscle were stained with Red Sirius and quantified using Histolab Software (marked in blue), data were normalized with total surface of each muscle (orange line surrounding the sections), bars represent 500 μm. (E) Quantification is presented in bar graph and showed 4.1±0.1 fold increase of fibrosis in TAΔDHPR (ΔDHPR) compared to TACtrl (c) (**P0.001, n=4).
