Fig. 4. Enhanced necroptosis in the muscle of MBKO mice. A. Necroptosis signaling in the gastrocnemius of female Fl/Fl and MBKO mice (6 months old). Quantification of the immunoblot is shown in the right panel (*: P < 0.05, **: P < 0.01, ***: P < 0.001, Student’s t-test, n = 3). B. The presence of necrosome in the gastrocnemius of female Fl/Fl and MBKO mice (6 months old) was determined by co-immunoprecipitation (top panel). The amount of RIP1 (middle panel) and RIP3 (bottom panel) input was also examined. C. Intramyocellular content of phosphorylated RIP3 in the gastrocnemius of female Fl/Fl and MBKO mice (6 months old) was examined by immunofluorescence staining. The yellow and green arrows indicate representative myofibers with high and low cellular content of phosphorylated RIP3, respectively. The scale bar represents 50 μm. D. IgG uptake in the gastrocnemius of female Fl/Fl and MBKO mice (6 months old) was determined by immunohistochemical staining. The scale bar represents 50 μm. E. Evans blue uptake in the gastrocnemius of female Fl/Fl and MBKO mice (6 months old) was determined by fluorescence microscopy. The yellow and green arrows indicate representative myofibers with ruptured and intact sarcolemma, respectively. The scale bar represents 50 μm.
