The gene TP53 (also known as protein 53 or tumor protein 53), encoding transcription factor P53, is mutated or deleted in half of human cancers, demonstrating the crucial role of P53 in tumor suppression. There are reports of nearly 250 independent germ line TP53 mutations in over 100 publications. The P53 protein has the structure of a transcription factor and, is made up of several domains. T...

p53 is a key tumor suppressor gene that is targeted for inactivation during human tumorigenesis. In this study, we produced and characterized polyclonal antihuman p53 antibody. The cDNA encoding the completehuman p53 protein was cloned into pGEX-4T-1 and expressed in Escherichia coli as a fusion protein with Schistosoma japonicum glutathione S-transferase (GST). The rabbits were immunized...

Inhibition of murine double minute 2 (MDM2)-p53 protein-protein interaction with small molecules has been shown to reactivate p53 and inhibit tumor growth. Here, we describe rational, structure-guided, design novel isoindolinone-based MDM2 inhibitors. X-ray crystallography, quantum mechanics ligand-based design, metabolite identification all contributed toward the discovery potent in vitro vivo...

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 ...

  Background and Objectives: The most prevalent malignancy among women is known to be breast cancer (BC). Several factors contribute to determining tumor prognosis and treatment strategies. In this study, the frequency and relevance of these factors are discussed. Materials and Methods: This cross-sectional study was carried out on 214 patients with BC, who referred to the Cancer Institute of...

introduction: colorectal cancer (crc) is one of the most prevalent cancers in the world. genetic disorders and dietary habits play a part in crc. the most important cancer suppressor gene is p53. different mutations rates in 7th exon of p53 gene are reported in different areas  which may have a relationship with prognosis of crc. this study examines the relationship between mutation in 7th exon...

Background & Aims: The role of P53 and proliferating cell nuclear antigen (PCNA) genes in inflamed and non-inflamed odontogenic cysts is related to cell proliferation but it is unclear. The aim of this study was immunohistochemical evaluation of P53 and PCNA expression in inflamed and non-inflamed dentigerous cysts Methods: In the present study, 23 dentigerous cysts (12 inflamed and 11 non-infl...

Abstract Background Silica exposure underlies the development of silicosis, one most serious occupational hazards worldwide. We aimed to explore interaction silica-induced epithelial–mesenchymal transition (EMT)-related transcripts with cellular metabolism regulated by p53. Methods knocked out p53 using CRISPR/Cas9 in human bronchial epithelial (HBE) cell line. The transcriptomic and metabolomi...
