Project description:Head and neck squamous cell carcinomas (HNSCC) driven by human papillomavirus (HPV) generally have a more favourable prognosis. We hypothesized that HPV-positive HNSCC may be identified based on a miRNA signature according to their specific molecular pathogenesis and are characterized by a unique transcriptome compared to HPV-negative HNSCC. We characterized the miRNA-expression patterns of the tumors from 229 head and neck squamous cell carcinoma patients by Agilent miRNA microarrays in order to define a HPV-predicting miRNA signature.

Project description:Genome wide DNA methylation profiling of HPV positive and HPV negative head and neck squamous cell cancer (HNSCC) samples. The Illumina Infinium 450k Human DNA methylation Beadchip v1.1 was used to obtain DNA methylation profiles across approximately 485577 CpGs in 4 HPV positive and 4 HPV negative HNSCC tumors

Project description:Persistent infection by high-risk human papillomaviruses (HPVs) is associated with the development of cervical cancer and a subset of anogenital and head and neck squamous cell carcinomas. Abnormal expression of cellular microRNAs (miRNAs) plays an important role in the development of cancer, including HPV-related tumors. MiRNA expression profile was investigated by microrray analysis in the HPV-positive cervical cancer cell lines SiHa (HPV16-positive cell line derived from a cervical squamous cell carcinoma), CaSki (HPV16-positive cell line derived from a metastatic cervical epidermoid carcinoma), and HeLa (HPV18-positive cell line derived from a cervical adenocarcinoma) and compared with primary HFKs and C33a (HPV-negative cervical cell line).

Project description:Head and neck cancer (HNC) is the fifth most common malignancy worldwide with an annual mortality rate of 200,000. About 90% of HNC can be classified as head and neck squamous cell carcinomas (HNSCC), of which approximately 75% are attributed to alcohol and tobacco consumption and 25 are associated with human papillomavirus (HPV), predominantly HPV16. HPV-associated OPC have better prognosis and a more favorable response to therapy as compared to HPV-negative tumors. Differences in risk factors, age of presentation, clinical behavior and gene expression profiles indicate that HPV-positive and HPV-negative tumors develop via different molecular mechanisms and are biologically distinct. This study aimed to compare the gene expression profiles of HPV-negative oropharyngeal squamous cell carcinoma (OPC) and normal benign uvula/tonsil tissues and determine what biological processes and pathways are affected in HPV-negative OPCs.

Project description:Genome-wide DNA methylation profiling of head and neck squamous cell carcinomas (HNSCCs). The Illumina Infinium 27k Human DNA methylation BeadChip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in fresh-frozen tumor tissues. Samples included 91 tumors from the oralpharynx and larynx, reflecting all stages of disease, 18 normal head and neck National Disease Research Interchange (NDRI) samples, and 213 normal control blood samples. Bisulphite-converted DNA from the 91 head and neck squamous cell carcinoma samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2.

Project description:Head and neck cancer (HNC) is the fifth most common malignancy worldwide with an annual mortality rate of 200,000. About 90% of HNC can be classified as head and neck squamous cell carcinomas (HNSCC), of which approximately 75% are attributed to alcohol and tobacco consumption and 25% are associated with human papillomavirus (HPV), predominantly HPV16. HPV-associated OPC have better prognosis and a more favorable response to therapy as compared to HPV-negative tumors. Differences in risk factors, age of presentation, clinical behavior and gene expression profiles indicate that HPV-positive and HPV-negative tumors develop via different molecular mechanisms and are biologically distinct. African American (AA) males have a higher incidence of HNC than any other racial/gender group, and a mortality rate almost three-fold that observed in European American (EA) males. Overall, AA patients tend to present with more HPV-negative OPC and have worse prognosis as compared to both HPV-positive and HPV-negative HNSCC in EA patients. Despite the unveiling of differential gene expression patterns, genetic and epigenetic profiles and the compilation of a mutational landscape along with preliminary TCGA data of HPV-related and unrelated HNC, the molecular determinants of the racial disparity in HNC are yet to be identified. This study aimed to compare the gene expression profiles of HPV-negative HNSCC from AA and EA patients, and determine their biological differences. ANALYSIS 2: Two-condition, on-color experiment: African American (AA) vs European American (EA) HPV-negative oropharyngeal squamous cell carcinomas. Biological replicates: 8 African American and 8 European American.
