A large proportion of human tumor-derived cell lines and primary tumor cells show methionine-dependent growth. This phenomenon refers to the ability of cells to grow in media containing methionine and the inability of cells to grow in media supplemented with methionine's precursor , homocysteine (Hcy). Methionine can be formed by two different pathways, the(More)
OBJECTIVE The gene encoding the methionine salvage pathway methylthioadenosine phosphorylase (MTAP) is a tumor suppressor gene that is frequently inactivated in a wide variety of human cancers. In this study, we have examined if heterozygosity for a null mutation in Mtap (Mtap(lacZ)) could accelerate tumorigenesis development in two different mouse cancer(More)
Mutations in the sodium channel gene, SCN1A (NaV1.1), have been linked to a spectrum of epilepsy syndromes, and many of these mutations occur in the pore region of the channel. Electrophysiological characterization has revealed that most SCN1A mutations in the pore region result in complete loss of function. SCN3A mutations have also been identified in(More)
Methylthioadenosine Phosphorylase (MTAP) is a tumor suppressor gene that is frequently deleted in human cancers and encodes an enzyme responsible for the catabolism of the polyamine byproduct 5'deoxy-5'-methylthioadenosine (MTA). To elucidate the mechanism by which MTAP inhibits tumor formation, we have reintroduced MTAP into MTAP-deleted HT1080(More)
