objective(s): glioblastoma is the most lethal tumor of the central nervous system. here, we aimed to evaluate the effects of exogenous delivery of p53 and a nanoformulation of curcumin called dendrosomal curcumin (dnc), alone and in combination, on glioblastoma tumor cells. materials and methods: mtt assay was exploited to measure the viability of u87-mg cells against dnc treatment. cells were ...
The expression of the tumor suppressor gene p53 was studied in Syrian hamster embryo cells neoplastically initiated with a single dose of 3-methylcholanthrene. Ten randomly selected individual 3-methylcholanthrene-transformed colonies were established in culture independently. Eight of these cell lines contained levels of p53 mRNA similar to those in primary embryo cells (p53+ cell lines), as m...
background and objectives: rcc is one of the most common genitourinary cancers. accurate prediction of prognosis would be valuable for adjuvant trial design, counseling and effectively scheduling follow up visits. p53 is a tumor suppressor gene that expresses a protein that involved in both cell-cycle arrests after dna damage and apoptosis. presence of mutated p53 protein in tumors has been rel...
adenosine receptor family especially a1 type is expressed in breast cancer cells in which p53 and caspase genes are wild-type. the aim of this study was to investigate the correlation between a1 receptor and either cell apoptosis or proliferation and also to recognize the relationship between this receptor and p53 and the expression of caspases 3, 8 and 9 in mcf-7 cell line. mcf-7 cells were tr...

Background: Nano-particle Titanium Dioxide (TiO2) is a noncombustible, odorless powder that is widely used in different fields of industries. Previous reports showed that chronic exposure to TiO2 adversely impacts the testicular tissue and down-regulates the antioxidant capacity and down-regulates the endocrine status of the testicles. Present study was designed in order to identify the role of...
Colorectal cancer is the third most common in men and second women globally. There a marked variation incidence of colorectal carcinoma worldwide, where western countries having high rate compared to others. p53 tumour suppressor gene one intensively studied markers tumours. Two were used, (oncoprotein p53) CEA (carcinoembryonic antigen) study. The 102 cases paraffin-embedded samples processed ...
IFN-inducible IFI16 protein (encoded by IFI16 gene at 1q23.1) is the human member of the IFN-inducible structurally related p200 family proteins. Increased expression of the IFI16 protein, a positive modulator of p53-mediated transcription, in normal old human diploid fibroblasts (HDF) is associated with cellular senescence-mediated cell growth arrest. However, the underlying mechanisms that co...
the current challenges in the management of esophageal cancer are to obtain a better understanding of underlying molecular alterations to provide new treatment options. we studied the p53 and bcl-2 protein expression in esophageal carcinomas to correlate molecular alterations with clinicopathological findings. tissue samples of 37 patients with advanced esophageal carcinoma were analyzed by imm...
Transient expression of the tumor suppressor gene p53 via adenoviral-mediated gene transfer induces apoptosis in glioma cells expressing mutant p53, while causing cell cycle arrest in cells with wild-type p53. To determine whether a change in p53 status of a wild-type p53-expressing cell line such as U-87 MG would alter its apoptotic resistant phenotype in response to Ad-p53 infection, we gener...
