A protein promotes an irregular heartbeat in animals
Animal experiments found that raising levels of the protein MAPK15 worsened heart muscle cell senescence and promoted atrial fibrillation, an irregular heartbeat.Animal experiments found that raising levels of the protein MAPK15 worsened heart muscle cell senescence and promoted atrial fibrillation, an irregular heartbeat.
Animal studyMechanisms
Who was studiedAnimals and atrial cardiomyocytes
What changedIncreasing MAPK15 in heart cells increased atrial fibrillation
The catchForced MAPK15 overexpression may not reflect the effects of naturally occurring protein levels
