Figure 7. Experimental evidence that CPA does not fully empty the SR of ASMC.

Figure 7

Tests of the model predictions shown in Fig. 6B–D, performed with mouse lung slices. (A) Significantly longer exposure to agonist+CPA and to CPA than in Fig. 6A still fails to maintain SOCE. (B) Same experiment as in (A) except that extracellular Inline graphic is removed before agonist is applied a second time, confirming the residual presence of Inline graphic in the SR and hence the partial efficacy of CPA to inhibit SERCA (scenario of Fig. 6D). (Insets show magnifications of selected time windows).
