Project description:Array Comparative Genomic Hybridization (CGH) profiling of Oral Leukoplakia (OPL) and early stage Oral Squamous Cell Carcinoma (OSCC) was performed to delineate candidate non-random chromosomal loci associated with disease progression and clinico-pathological parameters. The array CGH hybridizations were performed for 24 OPL and 38 OSCC samples with pooled gender matched controls. All tissue samples were collected after obtaining written informed consent.
Project description:The development of oral squamous cell carcinoma (OSCC) is a multistep process requiring the accumulation of genetic alterations. Oral carcinogenesis is a multifactorial process involving numerous genetic changes that affect the activity of oncogenes, tumor suppressor genes and other classes of disease-related genes.Therefore, to identify the responsive genes for progression of oral dysplasia or OSCC, we here performed CGH analysis to DNA from oral dysplasia and OSCC by microdissection Copy number analysis of Affymetrix 250K SNP arrays was performed for 8 oral dysplasia samples, 8 oral squamous cell carcinoma samples, using microdissection
