Lacking of endothelial Brg1 reduces heart functional decline after TAC. (A) Time course of left ventricular FS changes after sham/TAC operation in control and SclCreERT;Brg1fl/fl mice. P value: Student's t test. Error bar: SEM. (B–E) WGA immunostaining of control and SclCreERT;Brg1fl/fl hearts lacking endothelial Brg1 4 wk after sham or TAC operation. Original magnification: 200×. Green, WGA. (F) RT-qPCR quantitation of heart stress markers Myh6, Myh7, Anf, Bnp, and Serca2a in the heart ventricles 4 wk after sham/TAC operation in control and SclCreERT; Brg1fl/fl mice. P value: Student's t test. Error bar: SEM.
