ABSTRACT: Global gene expression in Head and neck squamous carcinoma (KB) cells treated with the combination of 2-DG + 6-AN followed by irradiation (2-Gy)
Project description:Whole genome expression profiling of head and neck squamous carcinoma (KB) cells comparing control untreated cells as well as irradited (2 Gy) alone cells with carcinoma cells treated with the combination of 2-DG and 6-AN followed by irradiation (2 Gy). Goal of this study was to study the global gene expression involved in radiosensitization of Head and neck squamous carcinoma (KB cells) treated with the combination of two metabolic modifers namely 2-deoxy-D-Glucose (2-DG) and 6-Aminonicotinamide (6-AN) followed by irradiation (2 Gy). This will enable us to understand the role of metabolic oxidative stress (MOS) involved in the radiosensitization of cancer cells and regulation between complex molecular circuits to develop better therapeutic approaches/ protection against oxidative damage.
Project description:Low passage head and neck squamous cancer cells (UT-14-SCC) were injected into the flanks of female nu/nu mice to generate xenografts. After tumors reached a size of 500mm3, they were treated with either sham RT or 15 Gy in one fraction. At different time points, days 0, 3, 10 and for controls and days 4, 7, 12, and 21 after irradiation, the tumors were harvested for global gene expression analysis and pathway analysis.

After tumors reached a size of 500mm3, they were treated with either sham RT or 15 Gy in one fraction. At different time points, days 0, 3, 10 and for controls and days 4, 7, 12, and 21 after irradiation, the tumors were harvested for global gene expression analysis and pathway analysis. Samples from the control time points (n=7) were compared to each of the post-irradiation time points (n=2). The changes in gene expression at each time point were compared to the other time points.
Project description:By employing a global gene expression profiling, we performed the differential gene expression analysis and the analysis of the molecular pathways which are deregulated in Hyperthermia (HT) and Radiation therapy (RT) treated SAS and FaDu spheroids from the head-and-neck cancer cell lines. The RNA-Seq analysis was done on FaDu and SAS spheroids treated with clinically relevant HT dose of 42.5°C for 60 minutes alone or in combination of single dose irradiation of 7 and 10 Gy for FaDu and SAS, respectively. The main pathways and networks modulated by the treatments (0.5 h after treatment) were identified using Gene Ontology (GO) enrichment analysis.
Project description:Microarrays were used to examine gene expression differences between human head and neck squamous cell carcinoma cell lines (FaDu, UTSCC8, UTSCC42a) grown in culture in comparison to a normal oral epithelial cell line. Gene expression data was integrated with global protein expression of head and neck squamous cell carcinoma cell lines and conditioned media to identify secreted protein markers up-regulated at the mRNA level in cancer cells versus the normal cell line. Total RNA obtained from head and neck squamous cell carcinoma cell lines and a normal oral epithelial cell line
Project description:The aim of the present study was to evaluate miRNAs as response predictors in FFPE head and neck samples from a phase II clinical trial designed to evaluate the feasibility of delivering cisplatin concurrent with radiotherapy after an induction chemotherapy (IC) regimen based on the combination of cisplatin plus paclitaxel in locally advanced head and neck squamous cell carcinoma (HNSCC) patients. For this purpose, we assessed the global miRNA expression profile of 15 HNSCC patients undergoing treatment, in order to identify miRNAs able to segregate resistant tumors from the sensitive ones, thus serving as markers to predict response. The results showed four miRNAs (miR-21, miR-494, miR-720 and miR-923) that were overexpressed in HNSCC FFPE samples.

Project description:This data was used to detect good biomarkers for head and neck squamous cell carcinoma and was integrated with transcriptome and miRNome data aiming to elucidate role of epigenetics on gene expression in head and neck squamous cell carcinoma.
Project description:We performed gene expression profiling of 39 head and neck cancer cell lines and 1 hela cell line, and classified them based on previous classification of head and neck squamous cell tumors from patients We performed gene expression profiling of 39 head and neck cancer cell lines and 1 hela cell line.
