Abstract

Transcriptional silencing induced by CpG island methylation is believed to be one of the important mechanisms of carcinogenesis. Checkpoint with fork head-associated and ring finger (CHFR) governs the transition from prophase to prometaphase in response to mitotic stress. This study was to analyze the relationship between the methylation of CHFR gene and the clinicopathologic features of gastric cancer, and the difference of results between methylation-specific polymerase chain reaction (MSP) and combined bisulfite restriction analysis (COBRA) in detecting aberrant methylation of CHFR gene in gastric cancer. Both MSP and COBRA methods were used to detect the promoter methylation of CHFR gene in gastric cancer specimens from 64 patients. The relationship between methylation status of CHFR gene and the clinicopathologic features of gastric cancer were analyzed using SPSS16.0. The methylation rates of CHFR gene promoter were significantly higher in gastric cancer samples than in the corresponding paracancer normal gastric mucosa by MSP (51.6% vs. 18.8%, P < 0.001). However, there was no significant correlation between methylation status of CHFR gene and the clinicopathologic parameters of gastric cancer, including age, gender, tum...Continue Reading

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
