Project description:The study was designed to identify differential expressed genes between human oral cavity carcinoma cell lines with and without LDBI knockout Three parental human oral cavity carcinoma cell lines were used as control, LDB1 was knocked out in the three parent cell lines to create KO cell lines.

Project description:Genome wide high resolution assay of copy number in a series of frozen, microdissected head and neck cancers originating from the oral cavity. The objective was to characterize areas of amplification and deletion in head and neck cancers arising from the oral cavity subsite.
Project description:Genome wide high resolution assay of copy number in a series of frozen, microdissected head and neck cancers originating from the oral cavity. The objective was to characterize areas of amplification and deletion in head and neck cancers arising from the oral cavity subsite. 31 tumors were snap frozen at the time of surgical resection, microdissected to >70% tumor content, and DNA extracted.
Project description:The aim of this study is to investigate the alterations in gene expression in Porphyromonas gingivalis W83 after inoculation in rat oral cavity. P.gingivalis W83 inoculation in rat oral cavity caused inflammatory responses in gingival tissues and destroyed host alveolar bone. Microarray analysis revealed that 42 genes were upregulated, and 22 genes were downregulated in the detected 1786 genes in the inoculated P.gingivalis W83. Products of these upregulated and downregulated genes are mainly related to transposon functions, cell transmembrane transportation, protein and nucleic acid metabolism, energy metabolism, cell division and bacterial pathogenicity.P.gingivalis W83 has a pathogenic effect on host oral cavity. Meanwhile, inflammatory oral environment alters P.gingivalis W83 gene expression profile. These changes in gene expression may limit the proliferation and weaken the pathogenicity of P.gingivalis W83, and favor themselves to adapt local environment for survival.
Project description:Oral Cavity Cancer Comparative analysis of gene expression using Affymetrix U133 plus 2.0 microarrays to compare differences between oral cancer samples (most HPV-) and adjacent "normal" mucosa. We have 24 matched pairs of tumor and normal from the same patient
