Moreover, impaired retinoic acid receptor β (RARβ) is implicated in cardiac pathologies, but its roles in handling cardiac intracellular calcium during myocardial hypertrophy remain unknown.

Bioinformatic analysis of human hypertrophic cardiomyopathy datasets revealed impaired RA signaling, marked by RARβ downregulation, which was confirmed in TAC hearts and ISO-treated neonatal rat ventricular myocytes (NRVMs).

This localized cAMP signaling modulates key Ca²⁺-handling proteins, including ryanodine receptor type-2 (RyR2), through channel-bound protein kinases and PDEs.

Ceramides can be converted to sphingosine by ceramidase and, in turn, phosphorylated by sphingosine kinase to yield sphingosine-1-phosphate (S1P), which binds to multiple cytoplasmic targets and activates S1P receptors via inside-out transport. This study was designed to determine the cellular source of ROS production elicited by SMase, the sphingolipid species responsible, and thereby, the mechanism of activation of &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; by sphingolipids.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods and results&lt;/h3&gt;&lt;div&gt;Whole-cell patch clamp experiments were conducted using freshly isolated rabbit ventricular myocytes. Inhibition of ceramidase with D-&lt;em&gt;erythro&lt;/em&gt;-MAPP, which increases the concentration of endogenous ceramides in the cell membrane, prevented activation of &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; upon exposure to SMase. Similarly, inhibition of sphingosine kinase with DL-&lt;em&gt;threo&lt;/em&gt;-dihydrosphingosine to prevent SIP formation by phosphorylation of sphingosine also completely inhibited SMase-induced Cl&lt;sup&gt;−&lt;/sup&gt; current. In contrast, addition of S1P to the bath solution elicited &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt;. ROS generated by both NADPH oxidase 2 (NOX2) and mitochondria previously were implicated in triggering &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt;. SMase-induced &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; activation was abrogated by blocking mitochondrial electron transport at Complex I with rotenone but was insensitive to blockade of NOX2 with either apocynin or gp91ds-tat. Moreover, diazoxide, which augments mitochondrial ROS production, evoked &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt;, and 5-HD, an inhibitor of this pathway, reversed the SMase and diazoxide-induced currents. Flow cytometry using C-H&lt;sub&gt;2&lt;/sub&gt;DCFDA-AM to assess cytoplasmic ROS in HL-1 myocytes confirmed the effects of the interventions on ROS production.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;Taken together, these data suggest S1P is the sphingolipid that triggers &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; in cardiomyocyte, and activation of &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; by SMase and S1P is due to ROS produced by mitochondria and appears independent of NOX2.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Translational perspective&lt;/h3&gt;&lt;div&gt;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;Cl,swell&lt;/em&gt;&lt;/sub&gt; modulates apoptosis, cell volume, action potential duration, and participation in mechanoelectrical feedback in cardiomyocytes.
