(Submitter supplied) In our previous study, we identified global genetic and epigenetic aberrations in the tumors of oral squamous cell carcinoma (OSCC) patients who were habitual smokers. We hypothesized that cigarette smoke might play a role in oral malignant transformation. DOK cell line is a dysplasitc oral keratinocyte derived from a heavy smoker with OSCC. The differentially expressed genes between DOK and normal human oral keratinocytes (HOK) may provide important information about OSCC carcinogenesis mediated by cigarette smoking.

(Submitter supplied) According to epidemiological studies, a vast majority, approximately 80%~90% of male OSCC patients in Taiwan habitually drink alcohol (A), and chew betel quid (B), and use cigarette (C). To assess the impact of these dietary factors on the epigenome, we conduct a high-throughput screen survey in an oral cancer cohort with exposure of A, B, and C. Results indicate aberrent methylation patterns are prevalent in OSCC patients with ABC risk factors.

To assess the impact of these dietary factors on the transcriptom, we conduct a high-throughput screen survey in an oral cancer cohort with exposure of A, B, and C. Results indicate several potential oncogenes and tumor suppressor genes are dysregulated in OSCC patients with ABC risk factors.

(Submitter supplied) We define how chronic cigarette smoke-induced time-dependent epigenetic alterations can sensitize human bronchial epithelial cells (HBEC) for transformation by a single oncogene. The smoke-induced, chromatin changes include initial repressive polycomb marking of genes later manifesting abnormal DNA methylation by 10 months. At this time, cells manifest epithelial to mesenchymal changes, anchorage-independent growth and upregulated RAS/MAPK signaling with silencing of hyper-methylated genes normally inhibiting these pathways and which are associated with smoking related NSCLC. more...

(Submitter supplied) MicroRNAs (miRNAs) participate in many biological processes and have emerged as key players in carcinogenesis. In order to identify changes in miRNAs specific for betelquid-associated oral squamous cell carcinoma (OSCC), we investigated the expression profiles of 858 miRNAs in a panel of 40 pairs of OSCC specimens and their matched non-tumorous epithelial counterparts. Eighty-four miRNAs were differentially expressed in the OSCC specimens compared to the matched tissue. more...

(Submitter supplied) Silencing of tumor suppressor genes plays a vital role in head and neck carcinogenesis. Aberrant hypermethylation in the promoter region of some known or putative tumor suppressor genes (TSGs) occurs frequently during the development of various cancers including head and neck squamous cell carcinoma (HNSCC). In this study we used an expanded mRNA expression profiling approach followed by microarray expression analysis to identify epigenetically inactivated genes in HNSCC. more...
