RATIONALE The Notch signaling pathway is important for cell-cell communication that controls tissue formation and homeostasis during embryonic and adult life, but the precise cell targets of Notch signaling in the mammalian heart remain poorly defined. OBJECTIVE To investigate the functional role of Notch signaling in the cardiomyocyte compartment of the(More)
Wolf-Hirschhorn syndrome (WHS) is caused by deletions in the short arm of chromosome 4 (4p) and occurs in about one per 20,000 births. Patients with WHS display a set of highly variable characteristics including craniofacial dysgenesis, mental retardation, speech problems, congenital heart defects, short stature and a variety of skeletal anomalies.

The unquestionable importance of the cardiovascular system for pre- and postnatal life has prompted dissection of the molecular mechanisms underlying its development. Serum and glucocorticoid-inducible kinase 1 (SGK1) is a serine/threonine kinase lying downstream of the phosphoinositide 3 (PI3) kinase pathway, whose embryonic function remains unknown. Here,(More)
Dynamic expressions of Homeobox (Hox) genes along the anterior-posterior axis of the neural tube (NT) are crucial in body patterning and neural crest (NC) development. At E12.5, Hoxb5 expression extends from the hindbrain throughout the entire NT with dorsally-restricted expression. By replacing the transactivation domain of Hoxb5 with a transcription(More)
A core principle of nervous system organization is the diversification of neuron classes into subclasses that share large sets of features but differ in select traits. We describe here a molecular mechanism necessary for motor neurons to acquire subclass-specific traits in the nematode Caenorhabditis elegans. Cholinergic motor neuron classes of the ventral(More)
