(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. BACKGROUND: Cell lines have been developed for modeling cancer and cancer progression. The molecular background of these cell lines is often unknown to those using them to model disease behaviors. As molecular alterations are the ultimate drivers of cell phenotypes, having an understanding of the molecular make-up of these systems is critical for understanding the disease biology modeled. more...

(Submitter supplied) BACKGROUND: Cell lines have been developed for modeling cancer and cancer progression. The molecular background of these cell lines is often unknown to those using them to model disease behaviors. As molecular alterations are the ultimate drivers of cell phenotypes, having an understanding of the molecular make-up of these systems is critical for understanding the disease biology modeled. METHODS: Six immortalized normal, one immortalized dysplasia, one self-immortalized dysplasia, and two primary normal cell lines derived from oral tissues were analyzed for DNA copy number changes and changes in both mRNA and miRNA expression using SMRT-v.2 genome-wide tiling comparative genomic hybridization arrays, Agilent Whole Genome 4x44k expression arrays, and Exiqon V2.M-RT-PCR microRNA Human panels. more...

(Submitter supplied) In order to identify biomarkers that contribute to genetic causes of OSCC, we attempt to identify copy number variation regions (CNV) in patients with OSCC. We identified and confirmed the clinical significance of amplification regions scattered from 8q22.2 to 8q24.3.

(Submitter supplied) Oral potentially malignant disorders (OPMDs) may precede oral squamous cell carcinoma (OSCC). Early detection of OPMDs has a crucial role in OSCC prevention. DNA aneuploidy and chromosomal aberrations are markers of genomic DNA damage and chromosomal instability (CIN), which is involved in cancer development. We explored the relationship among genomic DNA copy number aberrations (CNAs), histological diagnosis and DNA aneuploidy in OPMDs/OSCCs. more...

(Submitter supplied) Clinically evident oral lesions, oral epithelial dysplasia, precede development of oral squamous cell carcinomas (SCC) and are considered to transform to cancer by acquisition of genetic or epigenetic alterations. Here, we show that, +3q24-qter, -8pter-p23.1, +8q12-q24.2 and +20 are early events identifying two pathways to oral cancers that differ in clinical behavior. One or more of these copy number aberrations is present in the major subgroup (3q8pq20 subtype, 75-80% of lesions) that develops with chromosomal instability and risk for metastasis, while they are absent from the smaller and chromosomally stable non-3q8pq20 subgroup (20-25% of lesions) associated with low risk for metastasis. more...

(Submitter supplied) Chromosomal comparative genomic hybridization (CGH) and oligonucleotide microarrays were used to examine 8 HNSCC cell lines and a plot of gene expression levels relative to their position on the chromosome was produced. Three highly up-regulated genes, NT5C3, ANLN and INHBA, were identified on chromosome 7p14. These genes were subjected to quantitative real-time RT-PCR on cDNA and genomic DNA derived from 8 HNSCC cell lines. more...

(Submitter supplied) Genome wide DNA methylation profiling of normal and adjacent OSCC samples. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 4,50,000 CpGs in tissue samples. Total 21 samples were taken including 10 paired and 1 unpaired tissues. 6 were HPV Positive and 5 were HPV negative.

(Submitter supplied) Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations.

(Submitter supplied) A better understanding of molecular changes during oral tumorigenesis may help defining new personalized prevention strategies. In order to test this hypothesis, we analyzed whole-genome expression changes in a murine model of oral carcinogenesis, induced by an oral carcinogen (4-NQO) We generated genome-wide expression profiles of microdissected cells from murine tongue at each step of oral tumorigenesis: normal mucosa, hyperplasia, dysplasia and tumor.

(Submitter supplied) Objectives: Earlier studies involving a priori gene selection have identified promoter regions deregulated by DNA methylation changes in oral squamous cell cancers (OSCCs) and precancers. Interrogation of global DNA methylation patterns for such specimens has not been reported, though such analyses are needed to uncover novel molecular factors driving disease. Materials and Methods: We evaluated global DNA methylation patterns for 30 biopsies obtained from 10 patients undergoing surgical removal of an OSCC or carcinoma in situ (CIS). more...
