RATIONALE Excess signaling through cardiac Gbetagamma subunits is an important component of heart failure (HF) pathophysiology. They recruit elevated levels of cytosolic G protein-coupled receptor kinase (GRK)2 to agonist-stimulated beta-adrenergic receptors (beta-ARs) in HF, leading to chronic beta-AR desensitization and downregulation; these events are(More)
During mammalian palatogenesis, palatal shelves initially grow vertically from the medial sides of the paired maxillary processes flanking the developing tongue and subsequently elevate and fuse with each other above the tongue to form the intact secondary palate. Pathological palate-mandible or palate-tongue fusions have been reported in humans and other(More)
Background—Protease-activated receptor-1 (PAR-1) is the high-affinity receptor for the coagulation protease thrombin. It is expressed by a variety of cell types in the heart, including cardiomyocytes and cardiac fibroblasts. We have shown that tissue factor (TF) and thrombin contribute to infarct size after cardiac ischemia-reperfusion (I/R) injury.(More)
The expression of a muscle-specific variant of microtubule-associated protein 4 (mMAP4) has been analyzed during myogenesis of C(2)C(12) cells using an isoform-specific antibody. MMAP4 localizes to microtubules (MTs) and is expressed prior to a very early morphogenetic event, the formation of mononucleate spindle-shaped cells. MMAP4 protein appears at about(More)
