OBJECTIVE Cellular cardiomyoplasty using skeletal myoblasts is a promising therapy for myocardial infarct repair. Once transplanted, myoblasts grow, differentiate and adapt their electrophysiological properties towards more cardiac-like phenotypes. Voltage-dependent Na(+) channels (Na(v)) are the main proteins involved in the propagation of the cardiac(More)
Voltage-dependent potassium channels contribute to the electrical properties of nerve and muscle by affecting action potential shape and duration. The complexity of the currents generated is further enhanced by the presence of accessory beta subunits. Here we report that while all Kvbeta mRNA isoforms are present in rat brain, muscle tissues express only(More)
Lymphangioleiomyomatosis (LAM) is a rare lung-metastasizing neoplasm caused by the proliferation of smooth muscle-like cells that commonly carry loss-of-function mutations in either the tuberous sclerosis complex 1 or 2 (TSC1 or TSC2) genes. While allosteric inhibition of the mechanistic target of rapamycin (mTOR) has shown substantial clinical benefit,(More)
