Genomic copy number variation in head and neck squamous cell carcinoma cell lines

Project description:Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer world wide, and survival rates range from 40-80% depending on subsite. As novel treatment strategies are investigated, comprehensively characterized cell lines representative of the diversity seen in patients will be crucial to correlating genetic and phenotypic features with therapeutic response. The University of Michigan has generated a large panel of HNSCC cell lines that are utilized in laboratories worldwide. Here, we performed Oncoscan array analysis for 33 of these cell lines along with 2 HNSCC lines derived elsewhere to inform selection of model systems for future studies.

Genetic and Epigenetic Somatic Alterations in Head and Neck Squamous Cell Carcinomas Are Globally Coordinated but Not Locally Targeted (Affymetrix Copy Number)

Project description:Solid tumors, including head and neck squamous cell carcinomas (HNSCC), arise as a result of genetic and epigenetic alterations in a sustained stress environment. Since it has been hypothesized that epigenetic alterations may act by providing the second carcinogenic hit in gene silencing, we sought to identify genome-wide DNA copy number alterations and CpG dinucleotide methylation events and examine the global/local relationships between these types of alterations in HNSCC. Importantly, we found that the global pattern of copy number alterations in these tumors was significantly associated with tumor methylation profiles. However, at the local level, gene promoter regions did not exhibit a correlation between copy number and methylation , and the spectrum of genes affected by each type of alteration was unique. A case-series of 19 tumors and matched blood references were hybrizided to Affymetrix Human Mapping 500k arrays and copy number was determined via HMM with Copy Number Analysis Tool v4.0.1. This study was designed to investigate the relationship between copy number and DNA methylation alterations in head and neck squamous cell carcinoma. Data in this submission relates to the copy number portion only. Each patient tumor has been de-identified and assigned a number (1-19) and the blood samples with the same number correspond to the respectively-numbered tumor. The supplementary file 'GSE20939_tumor_copy_number.txt' contains the (blood normalized) copy number calls for each tumor sample.

Somatic copy number alterations associating with alcohol drinking and smoking in head and neck squamous cell carcinoma

Project description:Background: The most important risk factors for head and neck squamous carcinoma (HNSCC) are tobacco smoking and alcohol consumption, while subgroups are caused by infection with human papillomaviruses (HPV) or Epstein-Barr virus (EBV). Here, we studied alterations of somatic copy-number in whole genome, p16 protein and TP53 mutations by alcohol drinking, smoking and viral infections. Methods: We conducted a prospective cohort study. DNA obtained from tumors and margin samples as well as peripheral blood was assayed by array comparative genomic hybridization using Agilent Whole Human Genome 180K. Mutations of p53 gene by direct sequencing, detection of HPV by polymerase-chain-reaction (PCR), quantification of EBV by reverse transcription-PCR and p16 immunohistochemical (IHC) staining were also performed.
