Background and Aim: Transitional cell carcinoma of bladder (TCC) is a relatively common cancer among the males. The tumor progression is associated with expression or modulation of several gene products that control apoptosis and proliferation. The aim of this study was to assess the relationship between tumor expression of p53 and TCC histologic grade. Materials and Methods: In this prospecti...
Background: Hepatocellular carcinoma is the most common primary malignant tumor of the liver. The effect of some genes especially those involved in cell cycle regulation have been shown in the development of this cancer in several studies but there are some controversies about them yet. Materials and methods: The paraffin-embedded tissue samples of 25 patients (18 males and 7 females) with hep...
Background and Objectives: Researches have shown that progesterone influences the viability of breast cancer cells. The purpose of this study was to investigate the effect of progesterone on the viability of MCF-7 cell line and evaluation of Expression level of P53, Bax, and Bcl-2 Genes. Methods: In this laboratory-experimental study, MCF-7 cells were purchased from Pasture institute and div...
Melanoma is the deadliest form of skin cancer, primarily due to its high metastatic propensity and therapeutic resistance in advanced stages. The frequent inactivation p53 tumour suppressor protein melanomagenesis may predict promising outcomes for activators melanoma therapy. Herein, we aimed investigate antitumor potential p53-activating agent SLMP53-2 against melanoma. Two- three-dimensional...
Introduction: N-nitroso-N-methylurea (NMU) is a carcinogen from nitrosamines family, which has been used to induce breast cancer in rodents. This model of breast cancer is very similar to the estrogen dependent breast cancer in human. As a continuation of our recent works, in the present study, the expressions of both p53 and p27 were investigated in NMU-induced breast cancer in Wistar Albin...
Introdution:. Anaplastic thyroid carcinoma (ATC) is a type of thyroid gland malignancy that originates from the anaplastic cells of this gland. This kind of malignancy is highly invasive and patients have a poor response to treatment. In this study, the effect of curcumin on apoptosis and p53 and PARP genes expression of the human anaplastic thyroid carcinoma cell line (SW-1736) examined. Curcu...
Background: Recently the use of “two tier" grading system in which ovarian serous carcinoma was classified as low-grade or high-grade in comparing to preceding system has improved authority in prognosis and survival. This approach is simplistic, reproducible, and based on biologic evidence. In this study, we reclassified ovarian serous carcinoma by a new two-tier system for grading and then eva...
Abstract A poptosis r elated protein in T GF-? s ignaling pathway (ARTS) was originally discovered cells undergoing apoptosis response to TGF-?, but ARTS also acts downstream of many other apoptotic stimuli. induces by antagonizing the anti-apoptotic proteins XIAP and Bcl-2. Here we identified pro-apoptotic Sept4/ARTS gene as a p53-responsive target gene. Ectopic p53 variety p53-inducing agents...
The tumor suppressor p53 is inactivated by mutation in about half of all tumors, making mutant a prime target for cancer therapy. Missense mutations R248W, R273H and R248Q are included the five most frequent total lead to more than 630 000 new diagnosed cases diseases world every year. These mutations, located at or near protein-DNA interface, inactivation loss direct p53-DNA interactions, caus...
Background: Cancer treatment methods can lead to male infertility .in this regard, cryopreservation of spermatogonial stem cells (SSC) and cell-to-person transplantation after the course of treatment to resolve the problem of infertility is a good one. The cryopreservation of SSC is an important process as it can help on the return of spermatogenesis. However, during this process, the stem cell...
