Laboratory Course Using Zebrafish to Uncover Changing Roles of Wnt Signaling in Early Vertebrate Development.

Coordinated signaling pathway activity directs early patterning to set up the vertebrate body plan. Perturbations in the timing or location of signal molecule expression impacts embryo morphology and organ formation. In this study, we present a laboratory course to use zebrafish for studying the role of Wnt signaling in specifying the early embryonic axes.

Correlation between structural heart disease and cardiac SARS-CoV-2 manifestations.

Background: The prognosis of COVID-19 patients with cardiac involvement is unfavorable and it remains unknown which patients are at risk. The virus enters cells via its receptor angiotensin-converting enzyme 2 (ACE2). Myocardial ACE2 expression is increased in structural heart disease (SHD).
