We investigated the effects of overexpression of the tuberous sclerosis-1 and -2 (TSC1/2) gene products (hamartin and tuberin, respectively) in the human kidney epithelial cell line 293 with an inducible expression system. As we had observed previous

Ras GTPases, which play a pivotal role as transducers of various mitogenic and differentiation signals, function as molecular switches, cycling between an inactive GDP-bound state and an active GTP-bound state (33). Ras is negatively regulated by GTP

Tuberous sclerosis is an autosomal dominant disorder characterized by the development of benign growths in many tissues and organs. Linkage analysis revealed two disease-determining genes on chromosome 9 and chromosome 16. The TSC2 gene on chromosome

Schwann cell proliferation is stimulated by contact with neurons or exposure to growth factor ligands for tyrosine kinase receptors, effects of which are potentiated by cAMP. Here we show that treatment of rat Schwann cells with recombinant human gli

The Raf-1 serine/threonine protein kinase plays a central role in many of the mitogenic signaling pathways regulating cell growth and differentiation. The regulation of Raf-1 is complex, and involves protein-protein interactions as well as changes in

Tuberous sclerosis (TSC) is a human genetic syndrome characterized by the development of benign tumors in a variety of tissues, as well as rare malignancies. Two different genetic loci have been implicated in TSC; one of these loci, the tuberous scle

The NF1 gene, which is altered in patients with type 1 neurofibromatosis, has been postulated to function as a tumor suppressor gene. The NF1 protein product neurofibromin stimulates the intrinsic GTPase activity of active GTP-bound Ras, thereby inac

A series of v-rasH effector domain mutants were analyzed for their ability to transform rat 2 cells at either low or high temperatures. Three mutants were found to be significantly temperature sensitive: Ile-36 changed to Leu, Ser-39 changed to Cys (

We are studying the biological activity and regulation of mammalian Ras protein in tumours and in physiological signalling. We have shown that GAP (the GTPase-activating protein) is a potent negative regulator of normal Ras in cells. Reduction or los

Loss of axonal contact characterizes Schwann cells in benign and malignant peripheral nerve sheath tumors (MPNST) from neurofibromatosis type 1 (NF1) patients. Tumor Schwann cells demonstrate NF1 mutations, elevated Ras activity, and aberrant epiderm
