Measles is a highly contagious viral disease and rapid identification and control of cases/outbreaks are important global health priorities. Measles was declared eliminated from the United States in March 2000. However, importations from endemic countries continued through out the last decade and in 2011, the United States reported its highest number of cases in 15 years. With a global snapshot...

Throughout the 1970s and 1980s, the Prince Edward Island Right to Life Association (RTLA) lobbied medical professionals, hospital boards, politicians, and neighbours to prevent the Charlottetown and Summerside hospital corporations, the only abortion providers on the Island, to eliminate their Therapeutic Abortion Committees. Because abortion committees were not mandatory and only hospital boar...

We conducted a quantitative analysis of the extent of de novo methylation of four CpG islands in human urinary transitional cell carcinomas of different stages and grades to determine how frequently these CpG islands became methylated in transition cell carcinomas during progression. The CpG islands included exon 5 of PAX6, exon 2 of p16, the 5' end of the deleted in bladder cancer gene, and th...

Methylation of promoter CpG islands in colorectal cancer (CRC) falls into two categories: age related and cancer specific. Most cancer-specific methylation at CpG islands occurs in a subset of cases that display the CpG island methylator phenotype (CIMP). The underlying cause of CIMP is not known. Using methylation-specific PCR, we studied 47 CRC patients for methylation at five loci to determi...

In this study, the relationship between CpG island methylation and smoking and DNA methyltransferase in the occurrence and development of lung adenocarcinoma was explored by detecting p16 promoter methylation status. Protein and mRNA levels of p16 were detected by immunohistochemistry and in situ hybridization assays. p16 gene promoter and exon 1 CpG island locus Hap II sites methylation status...

The human insulin-like growth factor type 2 receptor gene (IGF2R) is biallelically expressed in a variety of fetal and adult tissues. In contrast, the imprinted mouse Igf2r gene is expressed exclusively from the maternally inherited chromosome. The mouse gene contains two CpG islands that are methylated in a parent-specific manner. Methylation of the CpG island in the promoter region occurs on ...

BACKGROUND The Bcl-2 protein family members have known as essential controllersof mitochondrial pathway of apoptosis. Bax has been implicated as potential tumor suppressor in certain solid tumors such as breast and colorectal carcinoma. DNA methylation of promoter associated CpG islands has known as a common mechanism for gene inactivation in tumor cells. METHODS The Methylation Specific PCR ...

Methylation of a CpG island is a faithful marker of silencing of its associated gene. Different approaches report the methylation status of a CpG island based on the determination of one or a few CpG sites by assuming the homogeneity of methylation along the element. This strategy is frequently applied in both locus-specific and genome-wide studies, but often without a validation of the represe...
