The p53 protein function is essential for the maintenance of the nontumorigenic cell phenotype. Pancreatic tumor cells show a very high frequency of p53 mutation. To determine if restoration of wild type p53 function can be used to eliminate the tumorigenic phenotype in these cells, pancreatic tumor cell lines, PANC-1 and HTB80, differing in p53 status were stably transfected with exogenous wil...

PKC isozymes are involved in the modulation of cellular pathways related with tumor progression, acting as a suppressor or promoter. In cancer cells, PKCs mutated, and most common type is loss function. This paper focuses on effect PKCδ mutation gastric cancer. LOF occurs throughout catalytic kinase domains PKCδ, disrupting activation function kinase. domain, there various potential targets, su...

p53 is one of the gene that has important role in human cell cycle and in the human cancers too.models of codon substitution make it possible to separate mutational biases in the dna fromselective constraints on the protein, and offer a great advantage over amino acid models forunderstanding the evolutionary process of proteins and protein-coding dna sequences. in thiswork, we investigated abou...

background: breast cancer is one of the most common malignancies among iranian women; however, its clinicopathological feature is uncertain. we pioneered a genetic counseling program among patients with breast cancer and their families in isfahan. this is the first report of this program. methods: this was a descriptive cross-sectional study on women with breast cancer registered in ala cancer ...

PURPOSE Although survival with a p53 missense mutation is highly variable, p53-null mutation is an independent adverse prognostic factor for advanced stage ovarian cancer. By evaluating ovarian cancer survival based upon a structure function analysis of the p53 protein, we tested the hypothesis that not all missense mutations are equivalent. EXPERIMENTAL DESIGN The p53 gene was sequenced from...

BACKGROUND p53 plays a key role in the apoptotic event induced by chemotherapeutic agents. Mutation of p53 gene has been observed in various spontaneous tumors in humans and is associated with a poor prognosis. p53 abnormalities have been evaluated in several tumors in dogs; however, the association of p53 gene mutation with clinical outcome in dogs with lymphoma has not been documented. HYPO...

PURPOSE The p53 gene is one of the most frequently mutated genes in breast cancer. We investigated the patterns and biologic features of p53 gene mutation and evaluated their clinical significance in Korean breast cancer patients. METHODS Patients who underwent p53 gene sequencing were included. Mutational analysis of exon 5 to exon 9 of the p53 gene was carried out using polymerase chain rea...

During a search for causative genes in patients with concurrent multiple primary colon tumours, we found a novel case with a germline mutation of the p53 gene, from GCC (Ala) to GTC (Val) at codon 189. Of the six primary colon tumours that this patient had, one large advanced carcinoma exhibited a somatic p53 mutation and a somatic APC mutation, in addition to the germline p53 mutation. Two ear...

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...
