The merlin tumor suppressor localizes preferentially in membrane ruffles. The cumulative inactivation of tumour suppressor genes and/or the amplification of oncogenes lead to progressively more malignant astrocytic tumours. Repression of proliferation-associated genes by the formation of heterochromatin serves to block cellular division and so acts as a potent tumour suppressor mechanism. However, in every case, the valence of the regression coefficient was of the same valence as the bivariate correlation, thus ruling out suppressor effects. One could speculate that selection for suppressors of a wing mutation would be more critical to the species than suppressors of an eye colour mutant. Methods of estimation using suppressor variables, curvilinear regression equations, qualitative differentiae, etc., have been discussed extensively. Proteins related to nuclear proto-oncogene- and tumor suppressor geneproducts. Pathogenesis of persistent hyperplastic primary vitreous in mice lacking the arf tumor suppressor gene. Our data show that these suppressor modifiers exist in natural populations. Cyclin-dependent kinase inhibitors play a fundamental role in regulating cellular proliferation and often show tumour suppressor actions. The retinoblastoma tumor suppressor modifies the therapeutic response of breast cancer. Therefore, formation of heterochromatin may be viewed as a tumour suppressor mechanism. These steps include inactivation of tumour suppressor genes and activation of oncogenes. However, the tumour suppressor activity of these genes is not certain.
