Project description:DNA methylation analysis in oropharyngeal squamous carcinoma (OPSCC) samples and oropharyngeal non-cancerous mucosa samples. Infinium HumanMethylation450 BeadChip was used to obtain DNA methylation profiles across 485,577 CpG sites. Total samples included 89 OPSCC samples and 5 non-cancerous mucosa samples.
Project description:DNA methylation analysis in oropharyngeal squamous carcinoma (OPSCC) samples and oropharyngeal non-cancerous mucosa samples. Infinium MethylationEPIC BeadChip Kit was used to obtain DNA methylation profiles across more than 850,000 CpG sites. Total samples included 89 OPSCC samples and 5 non-cancerous mucosa samples.
Project description:Methylation of CpG Islands within promoter regions of genes has been associated with gene silencing, suggesting loss of tumor suppressor function and tumorigenesis. The northeastern states of India are leaders in the country for cancers of several sites. Almost no reports are available of any DNA methylation biomarker for oropharyngeal cancers of the northeastern states. The present study aimed to identify targets of CpG hypermethylation and hypomethylation in oropharyngeal cancer prevalent in northeast India. Using Illumina Infinium Human Methylation 450K microarray platform a genome wide screening has been done for differentially methylated genes, including genes not previously implicated in carcinogenesis. Differential gene expression correlated to their methylation status was elaborated using transcriptome profiling. The new genes identified may be used to develop promising panels of DNA Methylation biomarkers for oropharyngeal screening and detection at a very early stage.
Project description:Genome wide DNA methylation profiling of normal whole blood samples. The data consist of 43 samples with Illumina HumanMethylation450 BeadChip data. Bisulphite converted DNA from 43 of these samples were hybridized to the Illumina Infinium 450k Human Methylation Beadchip.
