We investigated the effects of melatonin, cetuximab and cisplatin treatments alone or in combination on PANC-1 cells from a human pancreatic carcinoma ductal cell origin through viability gene expressions. The were left for 48 h incubation after applying chemicals cells. metabolic substances at end measured by MTT assay. expressions p21, p27, p53, p57, MDM2 KRAS determined RT-PCR. use melatonin...

introduction: human hematopoietic stem cells (hhscs) have been used for transplantation in hematologic failures. because the number of hhscs per cord blood unit is limited, the expansion of these cells is important for clinical application. it has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hhscs. in this regard, cord blood cd34+ cells expanded a...

The Effect of Endurance Training with Nano-Curcumin Supplementation on p53-p21 Axis and TERF2 Gene Expression in Muscle Tissue Male Wistar Rats: An Experimental Study

In human colorectal cancer (CRC), TP53 is one of the most important drives genes; it a key regulator apoptosis. The dysfunction gene critical event in development CRC this context, we aimed to evaluate expression Tp53 patients and establish correlation between overexpression p53 with clinical pathological features Colorectal Carcinoma (CRC). This study enrolled 32 carcinoma. was investigated by...

Background: Glaucomatous neuropathy is a type of cell death due to apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (POAG) has been studied in some ethnic groups. This study is the first association analysis of POAG and p53 codon 72 polymorphism in Iranian patients...

Background: Prostate cancer is one of the most commonly diagnosed cancers in males. Tumor suppressor gene p53 plays an important role in causing cell cycle arrest and allowing apoptosis to proceed. Objective: To investigate the expression of p53 protein and its relation to apoptosis and prostate cancer traditional prognostic indicators. Methods: In this study expression of p53 was examined in p...

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...

the p53 protein is expressed in all normal cells and appears to function in cell cycle regulation. abnormally higli levels of the protein are found in many different types of cancer. in breast cancer, overexpression of p53 is associated with point mutations within highly conserved regions of the p53 gene. these altered genes encode stable p53 protein that can be detected by standard immunohisto...

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...
