background there is evidence of a possible etiological role of human papillomaviruses (hpvs) in the development of colorectal cancer. loss of p53 tumor suppressor gene function has been found in many malignancies and it can occur in a variety of ways, including gene mutation and interaction with the e6 protein of oncogenic hpvs. the objective of this study was to determine the prevalence of hpv...

Background: P53 tumor suppressor gene mutation is one of the most common genetic alterations in human malignancies. The mutated from of the gene is stable and can be detected with immunohistochemistry methods. There is much controversy about the expression rate of this gene in malignant melanoma. Objective: To determine the frequency of the P53 antigen expression by sex, age, type and thickness...

Background and purpose: Gastric carcinoma is one of the most common malignancies and its early diagnosis can be effective in the treatment method and the rate of the patients’ survival. Ïn the past recent years, many genes have been identified which may have relationship with the prognosis of this disease and the patient’s survival. This study is going to investigate the rate and pattern of p53...

Introduction & Objective: Basal cell carcinoma is the most common malignant tumor in humans. The role of ultraviolet radiation is well known in pathogenesis of BCC. More recently some immunohistochemical markers such as p53 gene and Ki-67 antigen are suggested in the pathogenesis. Some of the recent studies correlate these markers to recurrence or metastasis of the tumor. This study is done t...

background and aim: squamous cell carcinoma is the eighth common cancer and forms 94% of oral malignancies. nowadays, many molecular and genetic changes have been known to affect tumoral behavior which might be good for drug production and gene therapy. it has been known that mutated p53, overexpression of p63 as an oncogene and hpv infection are correlated with clinicopathological behavior of ...

Abstract Background: Adult T-cell leukemia/lymphoma (ATLL) is caused by human T-cell lymphotropic virus type-1 (HTLV-1).  HTLV-1 oncogenes can induce malignancy through controlled gene expression of cell cycle checkpoints in the host cell. HTLV-I genes play a pivotal role in overriding cell cycle checkpoints and deregulate cellular division. In this study, we aimed to determine and comp...

Recent studies have shown that FMS-like receptor tyrosine kinase 3 (Flt3) has a beneficial effect on cardiac maladaptive remodeling. However, the role and mechanism of Flt3 in mitochondrial dynamic imbalance under stress remains poorly understood. This study aims to investigate how regulates p53-mediated optic atrophy 1 (OPA1) processing fragmentation improve Mitochondrial cardiomyocytes was in...

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...
