In our latest podcast we present the article by Wang et al., which explores regulation of sodium-calcium exchange by phospholemman and the possible role of that in cardiac stress responses (such as fight-or-flight). Associate Editor W. Gil Wier moderates a discussion with renowned expert Donald M. Bers (University of California-Davis) and lead author Joseph Y. Cheung (Thomas Jefferson University), who examinethis innovative study and ponder the way to pin down the role of phospholemman at the molecular level.
