Figure 4: BAG3 Overexpression Increases Peak I

L-type Ca2+ current (ICa) ([Ca2+]o 2 mmol/l) in 8 Sham-GFP, 8 MI-GFP, and 6 MI-BAG3 myocytes (3 mice each group) are measured at baseline (A) and after 1 μmol/l isoproterenol (B). Error bars are not shown if they fall within the boundaries of the symbols. Abbreviations as in Figure 1.
