Interplay between promoter methylation and chromosomal loss in gene silencing at 3p11-p14 in cervical cancer

ABSTRACT: We performed integrative methylation, gene dosage and expression profiling to explore the interplay between promoter methylation and loss in gene silencing at 3p11-p14 in cervical cancer. Totally 26 hypermethylated genes were identified by comparing the methylation level of individual CpG sites with corresponding data of normal cervical tissue. Candidate methylation regulated genes in tumors were proposed from the correlation between methylation and gene expression. Integrated analysis of methylation, gene dosage and expression revealed three significant regulation patterns encompassing 8 hypermethylated genes; a methylation driven pattern, a gene dosage driven pattern, and a combined methylation and gene dosage driven pattern. For the LRIG1 gene, patients with both hypermethylation and l
