Project description:We demonstrate that ALDH2 knockdown increased multiple canonical pathways and transcriptions factors We used microarrays to analyze the potential mechanism by which ALDH2 regulates gene expression.
Project description:Epigenetic mechanisms play an important role in the cellular development and maintenance of cellular homeostasis. Any alteration of epigenetic mechanisms via the changes in DNA methylation and histone modification may lead to various diseases including cancer. The differential expression of histone modifiers has been observed in various malignancies. We used microarray to detail the differential gene-expression pattern of head and neck (HNC) cancer cells upon depletion of p21 activated kinase (PAK2). we identified distinct class of downregulated genes, majorly associated with cellular proliferation and tumorigenesis.
Project description:Genome-wide DNA methylation profiling of head and neck squamous cell carcinomas. 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 18 normal head and neck samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2.
Project description:We hypothesized that DKK3 may exert oncogenic function supecifically in head and neck squamous cell carcinoma (HNSCC). DKK3 knockdown in HNSCC cell resulted in decreased cellular proliferation, migration, invasion and in vivo tumor growth.
Project description:This SuperSeries is composed of the following subset Series: GSE25083: Global hypomethylation identifies loci targeted for hypermethylation in head and neck cancer: normal head and neck tissue GSE25089: Global hypomethylation identifies loci targeted for hypermethylation in head and neck cancer: HNSCC GSE25091: Global hypomethylation identifies loci targeted for hypermethylation in head and neck cancer: blood controls Refer to individual Series
