Fig. 7: SERCA activator CDN1163 partially rescued the PKD2 deficiency-associated contractile deficiency.

A Representative contractile traces of H7-CMs-hvCTS under 1 Hz electrical pacing before (black trace) and after (red or blue trace) 1 hr treatment with 1 μM CDN1163. The hvCTS samples with PKD2 knockdown are on the right, whereas those without PKD2 knockdown are on the left. Data summary showing that CDN1163 treatment improved the contractile function in hvCTS samples with or without PKD2 knockdown, regarding developed force (B), passive tension (C), rise time 90 (D), and decay time 90 (E). Mean ± SEM. n = 7. *P < 0.05; **P < 0.01; ***P < 0.001.
