(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) 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) 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...

(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) 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) Rationale: Lung carcinoma-in-situ (CIS) lesions are the pre-malignant precursor to lung squamous cell carcinoma. However, only half progress to invasive cancer in three years, while a third spontaneously regress. Whether modern molecular profiling techniques can identify those preinvasive lesions that will subsequently progress and distinguish them from those that will regress is unknown. We performed gene expression microarrays on CIS lesions, with a view to deriving a molecular signature predictive of future progression to invasive cancer.
