Project description:RNA-seq analysis was performed in primary NKTL (Natural killer T-cell lymphoma) samples and healthy tonsil samples to analyze gene expression changes in lymphoma sample.
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: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.
Project description:ChIP-seq analysis was performed in primary NKTL (Natural killer T-cell lymphoma) samples, normal tonsil samples and 2 cell lines to analyze acetylation of histone H3K27ac.
Project description:The effect of PDGF-DD on the gene expression of human tonsil ILC1 is unknown. We used microarray to determine the transcriptional differences between unstimulated and PDGF-DD-stimulated human tonsil ILC1.
Project description:To study characteristics of the orapharyngeal epithelia which may influence susceptibility or resistance to HIV, we performed microarray analysis of the tonsil and gingival epithelium.Tonsil epithelium has been implicated in HIV pathogenesis, but its role in oral transmission remains controversial. We performed microarray analysis of Laser Capture Microdissected tonsil and gingival epithelium. Our data revealed that genes related to immune functions such as antibody production and antigen processing were increasingly expressed in tonsil compared to the epithelium of another oro-pharyngeal site, gingival epithelium. Importantly, tonsil epithelium highly expressed genes associated with HIV entrapment and/or transmission, including the HIV co-receptor CXCR4 and the potential HIV binding molecules, FcRγIII, complement receptor 2, and various complement components. This increased expression of molecules involved in viral recognition, binding and entry may favor virus-epithelium interaction in an environment with reduced innate anti-viral mechanisms. Specifically, secretory leukocyte protease inhibitor, an innate molecule with anti-HIV activity, was minimal in the tonsil epithelium, in contrast to oral mucosa. Collectively, our data suggest that increased expression of molecules associated with HIV binding and entry coupled with decreased innate anti-viral factors may render the tonsil a potential site for oral transmission.

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.
