abstract objective: detection of p53 gene mutation on its codon 248 between iranian women with breast cancer by pcr-rflp. material and methods: dna extraction of tumor tissues was performed in 53 patients with primary breast cancer. designing primer for the sub-studying codon was performed with nti-vector software and detection of codon 248 mutation was done by msp i pcr_rflp. results: the soma...
One of the major bottlenecks in malaria research has been the difficulty in recombinant protein expression. Here, we report the application of the wheat germ cell-free system for the successful production of malaria proteins. For proof of principle, the Pfs25, PfCSP, and PfAMA1 proteins were chosen. These genes contain very high A/T sequences and are also difficult to express as recombinant pro...
BACKGROUND Bacillus subtilis produces and secretes proteins in amounts of up to 20 g/l under optimal conditions. However, protein production can be challenging if transcription and cotranslational secretion are negatively affected, or the target protein is degraded by extracellular proteases. This study aims at elucidating the influence of a target protein on its own production by a systematic ...
For high-throughput production of recombinant protein in Escherichia coli (E. coli), besides important parameters such as efficient vector with strong promoter and compatible host, other important issues including codon usage, rare codons, and GC content specially at N-terminal region should be considered. In the current study, the effect of decreasing the percentage of GC nucleotides and optim...
Objective(s) P53 is an important tumor suppressor, which is mutated in later stages of many cancers and leads to resistance to chemotherapy. The aim of this study was to reveal mutations of TP53 in colorectal cancer in Kerman province. Materials and Methods A total of Forty-three colon cancer specimens as paraffin block or fresh tissues, which passed stage IIIA, were selected. Three exons 5,...
the tp53 gene is one of the most frequently mutated genes amongst human malignancies, particularly tp53 codon 72 polymorphism. furthermore, an association between the tp53 codon 72 variants and prostate cancer has been reported in several studies. although some studies have indicated an association between the tp53 arg/arg variant and an increased risk for prostate cancer, other studies have sh...
background: in prostate cancer, mutated p53 alleles typically contain missense single-base substitution in codon 72 that resides within exons 5-8. stable p53 proteins in tumor cell nuclei have been associated with malignancy. a role of p53 is the regulation of drug transporters like abcc1 (mrp1) by an effect on promoter region.objectives: the objective of this study was to identify association ...
