title: A new G(q)-initiated MAPK signaling pathway in the heart.
abstract: Pathological cardiac hypertrophy involves auto/paracrine mediators acting through G(q/11)-coupled receptors. A novel signaling route stimulated by betagamma-subunits of G(q/11) results in the autophosphorylation of ERK1/2 on a new site and the nuclear retention of ERK1/2, thereby activating hypertrophic gene programs.
