Urinary-tract-related tumors are prone to simultaneous or heterogeneous multiple tumor development within the primary organ. Urologic have a very high risk of recurrence in long and short term. This may be related disruption homeostasis on genetic level, such as induction mutations due exposure various carcinogenic factors cancer suppressor gene functions. It is essential detect progression sig...

Background: The p53 tumor suppressor gene plays important roles in genomic stability. Several reports have noted racial differences in the prevalence of p53 genotypes at the codon 72 in patients with endometriosis.To study the association of endometriosis with p53 codon 72 polymorphism in the population of Isfahan. Materials and Methods: We undertook a case–control study to examine the possible...

The concept of tumor suppressor networks comes as a logical consequence of the increasing understanding of the biology of tumor suppressor genes and oncogenes. Indeed, it has been gratifying to realize during the past decade that the products of tumor suppressor genes and oncogenes are often involved in the kind of guardian–delinquent relationship, or cat-and-mouse game suggested by the genetic...

Spleen cells from mice with syngeneic tumor transplants are hyporesponsive in mixed-lymphocyte culture. The hyporesponsiveness is due to the activation of suppressor cells. Spleen from tumor-bearing mice, treated with mitomycin and added to normal mixed lymphocyte culture (with responding cells syngeneic to the added cells), inhibits proliferation of the responding cells. Suppressor activity in...
