    Calcium-driven regulation of voltage-sensing domains in BK channels

    Yenisleidy Lorenzo-Ceballos et al.
    Gating currents analysis at different Ca2+ concentrations of BK channels reveals a strong allosteric coupling between Ca2+- and voltage-sensing modules via equivalent contributions exerted by the RCK1 and RCK2 Ca2+-sites.

    Endothelial EphB4 maintains vascular integrity and transport function in adult heart

    Guillermo Luxán et al.
    EphB4 maintains critical functional properties of the adult cardiac vasculature, namely mechanical resistance and fatty acid transport capability, and thereby prevents dilated cardiomyopathy-like defects.

    Insights into electrosensory organ development, physiology and evolution from a lateral line-enriched transcriptome

    Melinda S Modrell et al.
    An unbiased transcriptomic approach reveals that developing paddlefish electrosensory organs express genes essential for mechanosensory hair cell development and synaptic transmission, and identifies candidates for mediating electroreceptor development and function.

    The Ca2+-activated cation channel TRPM4 is a positive regulator of pressure overload-induced cardiac hypertrophy

    Yang Guo et al.
    The TRPM4 ion channel has been identified as an important component in the causation of mechanical pressure overload-induced pathological left ventricular hypertrophy, which is a powerful predictor of cardiovascular mortality.
