Inhibition of p38α MAPK rescues cardiomyopathy induced by overexpressed β2 adrenergic receptor, but not β1 adrenergic receptor
... We examined the role of p38a MAPK in mediating cardiomyopathy in mice overexpressing b 1 -adrenergic receptor (b 1 -AR) or b 2 -AR by mating them with dominant-negative p38a (DNp38a) MAPK mice. Both b 1 -AR ...
