Project description:To investigate miRNA expression in human tonsil squamous cell carcinoma (SCC) compared to normal tonsil tissue. Two colour LNA Exiqon array. MicroRNAs were labeled at 3'-end with a P-CU-C3-Cy3 RNA linker. A mixture of 371 synthetic DNA reference oligonucleotides containing complementary sequences to all LNA probes was randomly labeled using the ULYSIS labeling kit.

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. ANALYSIS 6: Two-condition, one-color experiment: HPV-negative oropharyngeal tumor samples and normal benign uvula/tonsil tissues. Biological replicates: 16 HPV negtive samples and 4 Normal samples.

Project description:transcription profiling of human head and neck squamous cell carcinoma (HNSCC) samples vs. normal tonsil samples using a self-self hybridization experimental design on two-color arrays. Used to identify differentially expressed genes in tumor/normal samples, and compare the result to that of the same samples using the reference design experimental setting. Keywords: tumor/normal comparison 8 HNSCC tumor samples and 8 normal tonsil samples. Each was profiled using a self-self hybridization design, where two aliquots of the same sample were labeled with two different dyes (cy3 and cy5) and hybridize to the same array.

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. Viral oncoproteins are capable of transforming primary human keratinocytes from either genital or oral epithelia in vitro and most likely play the same role in vivo, by disrupting cell-cycle regulatory pathways leading to a genetic progression to ano-genital cancer and OPC. However, the precise mechanisms by which HPV mediates malignant transformation of keratinocytes in the upper digestive tract epithelia are not entirely clear. HPV E7-mediated inactivation of pRb results in overexpression of p16INK4A, which is commonly used as a clinical surrogate marker for HPV positivity/activity. However, high p16INK4A alone has insufficient sensitivity and specificity as a biomarker of HPV positivity in different mucosal sub-sites of HNC. Therefore, increasing emphasis is being placed on the assessment of viral load and E7 oncogene expression, resulting in further classification of HPV positive OPC as HPV-active and HPV-inactive. This study aimed to compare the gene expression profiles of HPV-inactive oropharyngeal squamous cell carcinoma (OPC) and normal benign uvula/tonsil tissues from European American patients and determine what biological processes and pathways are affected in HPV-inactive OPCs in this ethnic group. ANALYSIS 7: Two-condition, one-color experiment: European American (EA) HPV-inactive oropharyngeal tumor samples and normal benign uvula/tonsil tissues. Biological replicates: 4 EA HPV inactive samples and 4 EA Normal samples.
