Project description:transcription profiling of human head and neck squamous cell carcinoma (HNSCC) samples vs. normal tonsil samples using a two-color reference design experimental setting. Used to identify differentially expressed genes in tumor/normal samples, and compare the result to that of the same samples using the self-self hybridization experimental setting. Keywords: tumor/normal comparison 8 HNSCC tumor samples and 8 normal tonsil samples. One sample per array. Two-color reference design with a common reference sample (a modified version of the Stratagene Human Universal Reference) on each array.

HNSCC samples vs. normal tonsil samples: self-self hybridization design

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.

MiRNA array based, miRNA expression profiles of head and neck squamous cell carcinoma patients

Project description:MiRNA expression profiles were successfully examined through expression profiling of a total of 656 miRNAs between 2 head and neck squamous cell carcinoma (HNSCC) tissues (C) and their paired adjacent normal mucousal tissues (AN). In the study presented here, 2 head and neck squamous cell carcinoma (HNSCC) tissues (C) and their paired adjacent normal mucousal tissues (AN) were examined by miRNA array

Gene expression profiling of HPV-negative oropharyngeal cancers and Normal benign uvula, tonsil

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.
