Project description:Epigenome-wide association study (EWAS) of oral rinse samples from a cohort of 82 oral squamous cell carcinoma (OSCC) patients. The Illumina Infinium HumanMethylation450 Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in oral rinse samples.

The Illumina Infinium HumanMethylation450 Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in oral rinse samples. Bisulphite lsconverted DNA from the 82 oral rinse samples were hybridized to the Illumina Infinium HumanMethylation450 Beadchip
Project description:Epigenome-wide association study (EWAS) of oral rinse samples from a case-control study of 154 cases and 72 controls. The Illumina Infinium HumanMethylation450 Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in oral rinse samples.
Project description:Predictive Value of MicroRNAs in the Progression of Oral Leukoplakias Comparison of 10 samples from non-progressive leukoplakias (did not turn into oral squamous cell carcinoma), with 10 samples from progressive leukoplakias (turned into oral squamous cell carcinoma w/in 5 yrs)
Project description:We applied a combination of Methyl-CpG Immunoprecipitation (MCIp) and Human CpG Island microarrays to identify aberrant DNA methylation in eight low-grade breast invasive carcinomas and two pre-invasive breast tumors against ten normal breast tissues.

Project description:Understanding the dynamics of the immune microenvironment is critical to the development of immuno-prevention strategies for the prevention of oral potentially malignant disorders transformation to oral squamous cell carcinoma (OSCC). We generated gene expression profiles of the microdissected epithelial and stromal compartments normal mucosa, hyperplasia, dysplasia and invasive tumors in the 4-nitroquinolein (4-NQO) murine model of oral carcinogenesis. Most gene expression changes were observed in the stromal compartment and related to immune biological processes. Immune cell deconvolution identified infiltration by the macrophage population as the most important quantitatively especially at the stage of dysplasia. In 86 patients with oral leukoplakia, three M2 macrophages signatures were independently associated and highly predictive of improved oral cancer-free survival.
Project description:The CpG island methylator phenotype is common in both BRAF mutant colorectal cancer and their precursors, the sessile serrated adenoma (SSA). SSAs acquire dysplasia immediate prior to progressing to invasive cancer. Here we examine the methylome of the remnant non-dysplastic portion of dysplastic sessile serrated adenomas to identify changes that occur immediately prior to the development of overt histological dysplasia.
