Genomic DNA damage in oral potentially malignant disorders (OPMDs) and oral squamous cell carcinomas (OSCCs). Early detection of DNA aneuploidy and chromosomal aberrations in non dysplastic OPMDs.
Ontology highlight
ABSTRACT: 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. Samples from OPMDs and OSCCs were processed for high resolution DNA flow cytometry (hr DNA-FCM) to determine the relative DNA content expressed with the DNA index (DI). Additionally, on a subset of these samples, array-Comparative Genomic Hybridization (aCGH) analysis was performed on DNA obtained from diploid nuclei suspension or from aneuploid-enriched nuclei suspensions.
