Methylation-specific PCR (MSP) of the mouse p53 gene has not yet been reported. We searched the CpG islands, sequenced the bisulfited DNA, and designed PCR primers for methylation and unmethylation sites. DNA from a young mouse produced a strong PCR product with the unmethylated primer and a weaker band with the methylated primer. DNA from an old mouse produced bands of similar intensities with both primers. In radiation-induced tumors, DNA from an old mouse yielded similar bands with both types of primers. We suggest that MSP is a valuable technique for the epigenetic study of the mouse p53 gene.

Abstract The authors report a case of an intracranial meningioma that developed 33 years after radiation therapy for a pituitary tumor. Radiation-induced tumors form a distinct biological group with aggressive growth characteristics and a malignant potential.

The gene P53 can activate DNA repair proteins when DNA has sustained damage. So, it is an important factor in aging. Also, P53 gene can also be modified by mutagens (chemicals, radiation, or viruses), increasing the likelihood for uncontrolled cell division. For this importance, we collected thirty samples from Yarmouk hospital in Baghdad, Iraq. Twenty-nine from women patients carrying breast cancer and the last one was from healthy woman, and the samples that we have taken were embedded in paraffin wax. The extracted RNA from each samples was used to check the expression of a suppressor gene (P53) via Real time PCR. We designed primers of P53 gene on encoded sequence (Exon), to make sure generation a specific PCR product of P53 gene by converting mRNA to cDNA then PCR Product. The expression of each samples was fluctuated between 0.1 fold to 0.2 fold compared with the control (the healthy sample). The highest expression showed was samples 7 (0.2 fold), and the lowest expression showed was samples 27 (0.1 fold) that compared with control expression (sample 19). While the control expression was the highest (0.25 fold) among all samples. The results indicate that tumor may affects on a suppressor gene (P53) and can decrease the gene expression, and eventually can decrease the P53 suppressor protein that can be used it in the cell protection against cancer.
