A switch in species dominance of a recovering pelagic ecosystem.

Curr Biol 2021 Jul 21. Epub 2021 Jul 21.

School of Biological Sciences, University of Aberdeen, Aberdeen AB24 2TZ, UK.

Although many marine ecosystems have been adversely impacted by human activities, some are now recovering due to reductions in fishing pressure. Here, we document the recovery of an ecosystem subjected to intense anthropogenic activity for over 200 years, the Clyde Sea. This region once had productive fisheries for herring (Clupea harengus) and other fish, but these disappeared at the turn of the century. Read More

Molecular noise filtering in the β-adrenergic signaling network by phospholamban pentamers.

Cell Rep 2021 Jul;36(4):109448

Randall Centre for Cell and Molecular Biophysics, King's College London, SE1 1UL London, UK.

Phospholamban (PLN) is an important regulator of cardiac calcium handling due to its ability to inhibit the calcium ATPase SERCA. β-Adrenergic stimulation reverses SERCA inhibition via PLN phosphorylation and facilitates fast calcium reuptake. PLN also forms pentamers whose physiological significance has remained elusive. Read More

Cardiovasc Drugs Ther 2021 Jul 28. Epub 2021 Jul 28.

Department of Pharmacology, School of Pharmacy, Jilin University, Fujin Road, Changchun, 130021, Jilin, China.

In addition to the key role in hemostasis and thrombosis, platelets have also been wildly acknowledged as immune regulatory cells and involving in the pathogenesis of inflammation-related diseases. Since purine receptor P2Y12 plays a crucial role in platelet activation, P2Y12 antagonists such as clopidogrel, prasugrel, and ticagrelor have been widely used in cardiovascular diseases worldwide in recent decades due to their potent antiplatelet and antithrombotic effects. Meanwhile, the role of P2Y12 in inflammatory diseases has also been extensively studied. Read More
