carney complex/tyrosine

Ovine hereditary chondrodysplasia, or spider lamb syndrome (SLS), is a genetic disorder that is characterized by severe skeletal abnormalities and has resulted in substantial economic losses for sheep producers. Here we demonstrate that a non-synonymous T>A transversion in the highly conserved

Carney complex (CNC) is characterized by lentiginosis and myxomatosis together with a variety of endocrine, neural crest-derived, and other tumors, including primary pigmented nodular adrenocortical disease (PPNAD). PPNAD is characterized by lipofuscin-containing, autonomously functioning,

BACKGROUND Carney complex, a multiple neoplasia syndrome, characterized primarily by spotty skin pigmentation and a variety of endocrine and other tumors, is caused by mutations in PRKAR1A, the gene that codes for the RIalpha subunit of protein kinase A (PKA). PKA controls cell proliferation in many

The pathogenesis of tumour formation in the anterior pituitary has been intensively studied, but the causative mechanisms involved in pituitary cell transformation and tumourigenesis remain elusive. Most pituitary tumours are sporadic, but some arise as a component of genetic syndromes such as the

The rhythmic firing of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNc) is thought to be mediated by nifedipine-sensitive Ca(2+) channels, although an involvement of omega-conotoxin-sensitive Ca(2+) channels is also suggested. In an attempt to localize such Ca(2+) channels at
