Figure 1 illustrates the representative conventional and nanotechniques for DNA methylation analysis. Despite the challenges, an integration of genome-wide association studies with the molecular pathological epidemiology represents a promising area for personalized prevention and therapy of cancer.30This review focuses on the fundamental distinctions andattributes of the following methylation screening techniques: blotting, genomic sequencing, bisulfite sequencing, methylation-specific PCR, methylated DNA immunoprecipitation,microarray analysis, matrix-assisted laser desorptiontime-of-flight mass spectroscopy (MALDI-TOF MS), a nanowire transistor detection procedure, a quantum-dot (QD) nanoassay, single-molecule real-time (SMRT) detection, a fluorimetric assay, electrochemical detection, and atomic force spectroscopy.

Whether global hypomethylation and gene-specific hypermethylation are mutually exclusive or not remains ambiguous.16and17 CpG methylation analysis is useful in detecting the progression of tumor, classification of disease, diagnosis, and prognosis of various types of human cancer.

Although methylation inhibition is a targeted therapy, downstream effects are non-specific, causing cytotoxicity and making clinical predictions difficult.29 Molecular pathological epidemiology deals with the interrelationship between exogenous and endogenous factors, tumor biomarkers, and progression. Alterations in the methylation status of DNA are promising candidates for a highly specific and sensitive indicator of cancer diagnosis and prognosis.10, 11and12 Apart from carcinogenesis, DNA methylation is crucial for a variety of processes, such as genomic imprinting, X-chromosome inactivation, and suppression of repetitive elements.1and13Genome-wide hypomethylation results in chromosomal instability14 and increased mutation rates,15 whereas promoter hypermethylation suppresses gene transcription by either preventing transcription factors from binding to the gene or altering chromatin structure.1DNA hypermethylation contributes to oncogenesis by point mutation and inactivation of tumor suppressor gene, whereas hypomethylation may lead to chromosomal instability and activation of proto-oncogene.1 Tumor growth is characterized by genome-wide hypomethylation, accompanied by hypermethylation of tumor suppressor gene promoters caused by increased expression of DNA methyltransferases.2 Changes in DNA methylation in cancer include both global hypomethylation and gene-specific hypermethylation.
