| Genotype analysis in 4 types of tumor tissue showed allelic imbalance surrounding NIT2 locus; results show that NIT2 plays an important role in cell growth inhibition & links to malignancies, suggesting Nit2 may be a potential tumor suppressor candidate | None |
| Identification of the putative tumor suppressor Nit2 as omega-amidase, an enzyme metabolically linked to glutamine and asparagine transamination. | None |
| Molecular identification of omega-amidase, the enzyme that is functionally coupled with glutamine transaminases, as the putative tumor suppressor Nit2. | None |
