    <t>PABA/NO</t> treatment of HL60 cells results in temporal and dose-dependent increases in intracellular Ca 2+ . A) Time-dependent increases were assessed following treatment with 20 nM ThG; 25 µM PABA/NO; 25 µM PABA; 20 nM ThG after pretreatment with PABA/NO (15 µM, 30 min); 25 µM DEA NONOate B) Competitive inhibition of ThG (100 nM) - mediated increases in intracellular Ca 2+ by PABA/NO, purified homogeneous nitro-aromatic product (MW 622 Da), or PABA. C) Dose-dependent increases in Ca 2+ following PABA/NO (Control) or PABA were measured; in the presence of the intracellular Ca 2+ chelator BAPTA-AM (5 µM); or in the presence of the extracellular Ca 2+ chelator, <t>EGTA</t> (5 mM, long dashedline). The fluorescence measurements were recalculated as actual intracellular Ca 2+ concentrations (see Materials and Methods ). D) Kinetics of intracellular NO (left Y-axis) and Ca 2+ (right Y-axis, solid line) generation after PABA/NO (15 µM) addition. Data are the average representative traces (A and D) or mean ± SE (B, C) for 3 independent experiments.

    Protective effects of PMC-12 on cellular Ca 2+ -related ROS production in HT22 cells. Cells were pretreated with 10 μg/ml of PMC-12 for 24 h, followed by exposure to 5 mM glutamate for 24 h. Cells were treated with the specific Ca 2+ inhibitors, 1.5 mM <t>EGTA</t> or 10 μM <t>BAPTA-AM,</t> for 30 min before addition of PMC-12 or glutamate. ROS production was measured using a fluorescence plate reader and mean fluorescence intensity was expressed as the mean ± SEM of three independent experiments. ### P

    Excessive Ca 2+ -Independent Actomyosin Associations during Diastole Promote Enhanced Myocyte Shortening and Incomplete Relaxation of Hand > Act57B A295S Cardiomyocytes (A) M modes generated from the same region of a three-week-old Hand > Act57B WT heart reveal graded responses of cardiac diameters following exposure to distinct small-molecule compounds. Red arrowheads indicate the position of the heart wall edges during diastole, upon incubation with <t>EGTA/EGTA,AM,</t> and finally, following the addition of blebbistatin. Incubation with EGTA/EGTA,AM resulted in complete cessation of wall motion. Relative to the diameter during diastole, each treatment induced a slight increase in diameter across the heart tube. (B) Significant, incremental increases in cardiac diameters were verified for all genotypes following extra- and intracellular Ca 2+ chelation and upon blebbistatin incubation. (C) The average change in diameter across the heart wall in response to EGTA/EGTA,AM was similar among all lines. (D) Blebbistatin treatment prompted a significantly greater response across the wall of Hand > Act57B A295S hearts relative to that observed for Hand × yw and Hand > Act57B WT hearts. Data are presented as mean ± SEM (n = 21). ***p ≤ 0.001. See also Figure S3 .

    Effect of PF-IgGs on binding of Dsg1-coated beads to <t>HaCaT</t> cells. Beads were allowed to settle on the surface of HaCaT cells for 30 minutes (control). Number of bound beads was reduced by simultaneous incubation of <t>EGTA</t> (5 mM, 30 minutes). Incubation of monolayers with attached beads for an additional 30 minutes with IgG fractions from 2 patients (PF1- and PF2-IgG, 35 μg/ml each) as well as with a monoclonal antibody (1:50) directed against the extracellular domain of human Dsg1 significantly reduced the number of bound beads (label in white box and white bars). Immunoabsorption using Dsg1-coated beads but not control absorption using VE-cadherin–labeled beads completely abolished the effect of PF-IgGs on bead adhesion. Preincubation of HaCaT cells with PF-IgGs prior to bead settlement also reduced bead binding (label in gray box and gray bars) whereas preincubation of beads with PF-IgGs did not inhibit bead binding. In contrast, the monoclonal Dsg1 antibody reduced bead binding also when applied for preincubation with beads, indicating a different mechanism underlying the reduction of Dsg1 adhesion ( n = 6 for each condition).

A) Time-dependent increases were assessed following treatment with 20 nM ThG; 25 µM PABA/NO; 25 µM PABA; 20 nM ThG after pretreatment with PABA/NO (15 µM, 30 min); 25 µM DEA NONOate B) Competitive inhibition of ThG (100 nM) - mediated increases in intracellular Ca 2+ by PABA/NO, purified homogeneous nitro-aromatic product (MW 622 Da), or PABA. C) Dose-dependent increases in Ca 2+ following PABA/NO (Control) or PABA were measured; in the presence of the intracellular Ca 2+ chelator BAPTA-AM (5 µM); or in the presence of the extracellular Ca 2+ chelator, EGTA (5 mM, long dashedline). The fluorescence measurements were recalculated as actual intracellular Ca 2+ concentrations (see Materials and Methods ).

    Excessive Ca 2+ -Independent Actomyosin Associations during Diastole Promote Enhanced Myocyte Shortening and Incomplete Relaxation of Hand > Act57B A295S Cardiomyocytes (A) M modes generated from the same region of a three-week-old Hand > Act57B WT heart reveal graded responses of cardiac diameters following exposure to distinct small-molecule compounds. Red arrowheads indicate the position of the heart wall edges during diastole, upon incubation with EGTA/EGTA,AM, and finally, following the addition of blebbistatin. Incubation with EGTA/EGTA,AM resulted in complete cessation of wall motion. Relative to the diameter during diastole, each treatment induced a slight increase in diameter across the heart tube. (B) Significant, incremental increases in cardiac diameters were verified for all genotypes following extra- and intracellular Ca 2+ chelation and upon blebbistatin incubation. (C) The average change in diameter across the heart wall in response to EGTA/EGTA,AM was similar among all lines.

    Effect of PF-IgGs on binding of Dsg1-coated beads to HaCaT cells. Beads were allowed to settle on the surface of HaCaT cells for 30 minutes (control). Number of bound beads was reduced by simultaneous incubation of EGTA (5 mM, 30 minutes). Incubation of monolayers with attached beads for an additional 30 minutes with IgG fractions from 2 patients (PF1- and PF2-IgG, 35 μg/ml each) as well as with a monoclonal antibody (1:50) directed against the extracellular domain of human Dsg1 significantly reduced the number of bound beads (label in white box and white bars). Immunoabsorption using Dsg1-coated beads but not control absorption using VE-cadherin–labeled beads completely abolished the effect of PF-IgGs on bead adhesion. Preincubation of HaCaT cells with PF-IgGs prior to bead settlement also reduced bead binding (label in gray box and gray bars) whereas preincubation of beads with PF-IgGs did not inhibit bead binding. In contrast, the monoclonal Dsg1 antibody reduced bead binding also when applied for preincubation with beads, indicating a different mechanism underlying the reduction of Dsg1 adhesion ( n = 6 for each condition).
