Figure 1. — Loss of ENH protein expression does not alter steady-state mechanical properties of mouse myocardium. (A) Experimental protocol for simultaneous determination of Ca²⁺-activated tension and k_tr. (B and C) The passive (B) and maximum (C) Ca²⁺-activated tension generated by skinned right ventricular trabeculae isolated from the hearts of ENH^+/+ and ENH^−/− mice. (D) Tension–pCa relationships established in ENH^+/+ and ENH^−/− trabeculae. (E and F) The Hill coefficient (E) and pCa₅₀ (F) values established in ENH^+/+ and ENH^−/− trabeculae. Each data point is the mean and error bar the SEM.
