    Discrete cAMP pools in adult mouse SAN cells (A) Diagrams highlighting localization and schematic representation of the Epac1-camps-based FRET biosensors (ICU3) in the cytosol (cyt; 1), plasma membrane (PM; 2), sarcoplasmic reticulum (SR; 3), myofilaments (MF; 4), and nucleus (nuc; 5). The ICU3 is linked to a Kras-derived sequence for PM localization, to a phospholamban (PLB)-derived sequence for SR localization, to a troponin T (TnT) for MF localization, and to a nuclear localization signal (NLS) sequence for nucleus localization. Exemplary super resolution images of adult wild-type mouse SAN cells expressing the indicated ICU3 biosensor in the cytosol (B), PM (C), SR (D), MF (E), and nucleus (F). The biosensor-associated fluorescence (YFP) is in magenta. Cells were immunostained with specific markers (in cyan) for the PM (caveolin 3), SR (ryanodine <t>receptor</t> <t>2</t> <t>[RyR2]),</t> MF (phalloidin; phal), and nucleus (DAPI). Merged images and corresponding line profile analysis (for dotted line) show high degree of overlap between the YFP fluorescence linked to the biosensor and the corresponding cellular marker in all cases, except in cells expressing the cytosolic sensor, as expected. Dotted squares highlight expanded regions in the solid squares. (G) Scatterplot of Pearson's correlation coefficient for cyt/cav3, PM/cav3, SR/RYR2, MF/phal, and nuc/DAPI (n > 8 SAN cells per condition). Kruskal-Wallis with Dunn's multiple comparisons test was used to test statistical differences in Pearson's correlation coefficient between non-target and targeted sensors. Scatterplot of the FRET ratio change in response to 10 μM forskolin (fsk) + 100 μM IBMX (H) and cAMP concentration-response curves (I) generated in HEK cells expressing the different ICU3 sensors (n > 5 cells per condition). For the cAMP concentration-response curves, cells expressing the different ICU3 sensors were exposed to increasing concentrations of the membrane-permeable cAMP analog 8CPT-cAMP. Kruskal-Wallis with Dunn's multiple comparisons test was used to compare fsk + IBMX responses, and the extra sum-of-squares F test was used to compare the cAMP EC 50 response between sensors. (J) Average FRET ratio traces (mean, solid lines; SEM, shadow) in response to 100 nM isoproterenol (iso) or 10 μM fsk from adult wild-type mouse SAN cells expressing the cytosolic, PM, SR, MF, or nuclear ICU3 biosensors (n > 5 cells from three preparations per condition). Scatterplots of ΔR/R 0 (K) and normalized (L) FRET responses after application of iso or fsk. Statistical differences were assessed with two-tailed Mann-Whitney test for comparisons between iso and fsk responses in (H) Statistical differences in fsk responses between the different biosensors in H were assessed with a Kruskal-Wallis with Dunn's multiple comparisons test. Statistical differences in normalized iso responses between the different groups were assessed using a one-way ANOVA with Tukey's multiple comparisons test.

    Schematic diagram illustrating the mechanism through which TRPC7 positively regulates the automaticity of cardiomyocytes. G protein-coupled receptors (GPCRs) locating on the plasma membrane (PM) sense the external ligands such as hormones, neurotransmitters, and growth factors, transduce the signal to activate phospholipase C (PLC) which hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP 2 ) into inositol trisphosphate (IP 3 ) and diacylglycerol (DAG). TRPC7 is then directly activated by DAG, mediating the Ca 2+ influx. Ca 2+ permeated through TRPC7 may activate the forward mode of the Na + -Ca 2+ exchanger (NCX), leading Na + influx and depolarization. This depolarization would then accelerate diastolic depolarization (DD) and increase AP firing rate. On the other hand, Ca 2+ permeated through TRPC7 may also increase the activity of ryanodine receptor 2 (RyR2) locating on the SR, probably through CaMKII and phosphorylation of RyR2, leading to an increase of the localized calcium releases (LCRs). These LCRs are then coupled to inward NCX current, and subsequently accelerate the DD and AP firing rate. At the same time, CaMKII may also increase the phosphorylation of PLN, which subsequently increases the activity of SERCA. The enhancement of the activity of both RyR2 and SERCA result in the acceleration of CaTs

    Discrete cAMP pools in adult mouse SAN cells (A) Diagrams highlighting localization and schematic representation of the Epac1-camps-based FRET biosensors (ICU3) in the cytosol (cyt; 1), plasma membrane (PM; 2), sarcoplasmic reticulum (SR; 3), myofilaments (MF; 4), and nucleus (nuc; 5). The ICU3 is linked to a Kras-derived sequence for PM localization, to a phospholamban (PLB)-derived sequence for SR localization, to a troponin T (TnT) for MF localization, and to a nuclear localization signal (NLS) sequence for nucleus localization. Exemplary super resolution images of adult wild-type mouse SAN cells expressing the indicated ICU3 biosensor in the cytosol (B), PM (C), SR (D), MF (E), and nucleus (F). The biosensor-associated fluorescence (YFP) is in magenta. Cells were immunostained with specific markers (in cyan) for the PM (caveolin 3), SR (ryanodine <t>receptor</t> <t>2</t> <t>[RyR2]),</t> MF (phalloidin; phal), and nucleus (DAPI). Merged images and corresponding line profile analysis (for dotted line) show high degree of overlap between the YFP fluorescence linked to the biosensor and the corresponding cellular marker in all cases, except in cells expressing the cytosolic sensor, as expected. Dotted squares highlight expanded regions in the solid squares. (G) Scatterplot of Pearson's correlation coefficient for cyt/cav3, PM/cav3, SR/RYR2, MF/phal, and nuc/DAPI (n > 8 SAN cells per condition). Kruskal-Wallis with Dunn's multiple comparisons test was used to test statistical differences in Pearson's correlation coefficient between non-target and targeted sensors. Scatterplot of the FRET ratio change in response to 10 μM forskolin (fsk) + 100 μM IBMX (H) and cAMP concentration-response curves (I) generated in HEK cells expressing the different ICU3 sensors (n > 5 cells per condition). For the cAMP concentration-response curves, cells expressing the different ICU3 sensors were exposed to increasing concentrations of the membrane-permeable cAMP analog 8CPT-cAMP. Kruskal-Wallis with Dunn's multiple comparisons test was used to compare fsk + IBMX responses, and the extra sum-of-squares F test was used to compare the cAMP EC 50 response between sensors. (J) Average FRET ratio traces (mean, solid lines; SEM, shadow) in response to 100 nM isoproterenol (iso) or 10 μM fsk from adult wild-type mouse SAN cells expressing the cytosolic, PM, SR, MF, or nuclear ICU3 biosensors (n > 5 cells from three preparations per condition). Scatterplots of ΔR/R 0 (K) and normalized (L) FRET responses after application of iso or fsk. Statistical differences were assessed with two-tailed Mann-Whitney test for comparisons between iso and fsk responses in (H) Statistical differences in fsk responses between the different biosensors in H were assessed with a Kruskal-Wallis with Dunn's multiple comparisons test. Statistical differences in normalized iso responses between the different groups were assessed using a one-way ANOVA with Tukey's multiple comparisons test. Significance (∗) was considered at P < 0.05. Exact p values are available in . Data represent mean ± SEM.

    Figure Lengend Snippet: Discrete cAMP pools in adult mouse SAN cells (A) Diagrams highlighting localization and schematic representation of the Epac1-camps-based FRET biosensors (ICU3) in the cytosol (cyt; 1), plasma membrane (PM; 2), sarcoplasmic reticulum (SR; 3), myofilaments (MF; 4), and nucleus (nuc; 5). The ICU3 is linked to a Kras-derived sequence for PM localization, to a phospholamban (PLB)-derived sequence for SR localization, to a troponin T (TnT) for MF localization, and to a nuclear localization signal (NLS) sequence for nucleus localization. Exemplary super resolution images of adult wild-type mouse SAN cells expressing the indicated ICU3 biosensor in the cytosol (B), PM (C), SR (D), MF (E), and nucleus (F). The biosensor-associated fluorescence (YFP) is in magenta. Cells were immunostained with specific markers (in cyan) for the PM (caveolin 3), SR (ryanodine receptor 2 [RyR2]), MF (phalloidin; phal), and nucleus (DAPI). Merged images and corresponding line profile analysis (for dotted line) show high degree of overlap between the YFP fluorescence linked to the biosensor and the corresponding cellular marker in all cases, except in cells expressing the cytosolic sensor, as expected. Dotted squares highlight expanded regions in the solid squares. (G) Scatterplot of Pearson's correlation coefficient for cyt/cav3, PM/cav3, SR/RYR2, MF/phal, and nuc/DAPI (n > 8 SAN cells per condition). Kruskal-Wallis with Dunn's multiple comparisons test was used to test statistical differences in Pearson's correlation coefficient between non-target and targeted sensors. Scatterplot of the FRET ratio change in response to 10 μM forskolin (fsk) + 100 μM IBMX (H) and cAMP concentration-response curves (I) generated in HEK cells expressing the different ICU3 sensors (n > 5 cells per condition). For the cAMP concentration-response curves, cells expressing the different ICU3 sensors were exposed to increasing concentrations of the membrane-permeable cAMP analog 8CPT-cAMP. Kruskal-Wallis with Dunn's multiple comparisons test was used to compare fsk + IBMX responses, and the extra sum-of-squares F test was used to compare the cAMP EC 50 response between sensors. (J) Average FRET ratio traces (mean, solid lines; SEM, shadow) in response to 100 nM isoproterenol (iso) or 10 μM fsk from adult wild-type mouse SAN cells expressing the cytosolic, PM, SR, MF, or nuclear ICU3 biosensors (n > 5 cells from three preparations per condition). Scatterplots of ΔR/R 0 (K) and normalized (L) FRET responses after application of iso or fsk. Statistical differences were assessed with two-tailed Mann-Whitney test for comparisons between iso and fsk responses in (H) Statistical differences in fsk responses between the different biosensors in H were assessed with a Kruskal-Wallis with Dunn's multiple comparisons test. Statistical differences in normalized iso responses between the different groups were assessed using a one-way ANOVA with Tukey's multiple comparisons test. Significance (∗) was considered at P < 0.05. Exact p values are available in . Data represent mean ± SEM.

    Knockdown of TRPC7 decreased while overexpression of TRPC7 increased the phosphorylation of RyR2 and PLN, respectively, in NRVMs. Western blotting showing the expression of a total RyR2, b p(S2814)RyR2, c total PLN, and d p(T17) PLN in NRVMs infected with different adenoviruses to knockdown or overexpress TRPC7. e – h Bar charts showing the quantification of each protein from a – d . To eliminate the loading bias, intensity of each target protein was normalized to that of its corresponding β-tubulin. The change of TRPC7 expression did not alter the expression of total RyR2 and PLN. However, knockdown of TRPC7 decreased while overexpression of TRPC7 increased the phosphorylation form of RyR2 [p(S2814)RyR2] and PLN [p(T17)PLN].

    Schematic diagram illustrating the mechanism through which TRPC7 positively regulates the automaticity of cardiomyocytes. G protein-coupled receptors (GPCRs) locating on the plasma membrane (PM) sense the external ligands such as hormones, neurotransmitters, and growth factors, transduce the signal to activate phospholipase C (PLC) which hydrolyzes the phosphatidylinositol 4,5-bisphosphate (PIP 2 ) into inositol trisphosphate (IP 3 ) and diacylglycerol (DAG). TRPC7 is then directly activated by DAG, mediating the Ca 2+ influx. Ca 2+ permeated through TRPC7 may activate the forward mode of the Na + -Ca 2+ exchanger (NCX), leading Na + influx and depolarization. This depolarization would then accelerate diastolic depolarization (DD) and increase AP firing rate. On the other hand, Ca 2+ permeated through TRPC7 may also increase the activity of ryanodine receptor 2 (RyR2) locating on the SR, probably through CaMKII and phosphorylation of RyR2, leading to an increase of the localized calcium releases (LCRs). These LCRs are then coupled to inward NCX current, and subsequently accelerate the DD and AP firing rate. At the same time, CaMKII may also increase the phosphorylation of PLN, which subsequently increases the activity of SERCA. The enhancement of the activity of both RyR2 and SERCA result in the acceleration of CaTs
