To identify genes associated with radioresistant oral squamous cell carcinoma (OSCC), we compared gene expression signatures between OSCC cell lines exhibiting radioresistance and cells with radiosensitivity after X-ray irradiation in a dose-dependent manner using Affymetrix GeneChip analysis with Human Genome-U133 plus 2.0 GeneChip. The microarray data(More)
The aim of the present study was to clarify the clinical characteristics of postoperative delirium and to determine appropriate postoperative management for its prevention. The authors analysed 132 cases of primary surgery for oral carcinoma and observed 24 (18%) cases of postoperative delirium. Univariate analysis revealed that significant risk factors for(More)
Considerable evidence suggests that periodontal disease not only is caused by bacterial infection but also is associated with host susceptibility. Using in-house cDNA microarray analysis, we attempted to identify gene expression changes in human periodontal ligament (PDL)-derived cells with and without treatment with lipopolysaccharide (LPS) extracted from(More)
BACKGROUND MicroRNAs (miRNAs) are involved in essential biological activities, and have been reported to exhibit differential expression profiles in various cancers. Our previous study demonstrated that intercellular adhesion molecule-2 (ICAM2) inhibition induces radiosensitisation in oral squamous cell carcinoma (OSCC) cells. Thus, we hypothesised that(More)
Frequent allelic imbalances (AIs) including loss of heterozygosity and microsatellite instability on a specific chromosomal region have been identified in a variety of human malignancies. The objective of our study was to assess the possibility of prognostication and monitoring of oral squamous cell carcinoma (SCC) by microsatellite blood assay. DNA from(More)
Collagens represent a large family of structurally related extracellular matrix proteins containing unique triple helical structure. One of the characteristics of this structural protein is its extensive post-translational modifications that have major effects on molecular assembly, stability, and metabolism. Hydroxylation of specific lysine residues is one(More)
Oral squamous cell carcinomas (OSCCs), a major public health problem worldwide, are the most common neoplasms of the head and neck. The most important prognostic indicator for patients with OSCC is metastasis to cervical lymph nodes or distant organs. Galectin-9 is correlated with cellular adhesion and aggregation in melanoma cells. To investigate(More)
Stathmin is an intracellular phosphoprotein that is overexpressed in a number of human malignancies. Our previous study using proteomic profiling showed that significant upregulation of stathmin occurs in oral squamous-cell carcinoma (OSCC)-derived cell lines. In the current study, to determine the potential involvement of stathmin in OSCC, we evaluated the(More)
To characterize cancer-related gene expression changes in oral squamous cell carcinomas (OSCCs), we compared the gene expression profiles in OSCC-derived cell lines with human normal oral keratinocytes (HNOKs). Microarray analysis identified 166 genes that were up-regulated in OSCC-derived cell lines. Gene ontology analysis showed that cancer-related(More)
The structure and function of chromatin can be altered by modifications to histone. Histone acetylation is a reversible process governed by histone acetyltransferases and histone deacetylases (HDACs). HDAC6 is a subtype of the HDAC family that deacetylates alpha-tubulin and increases cell motility. We investigated the expression levels of HDAC6 mRNA and(More)
