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)
This study was designed to identify specific gene expression changes in tongue squamous cell carcinomas (TSCCs) compared with normal tissues using in-house cDNA microarray that comprised of 2304 full-length cDNAs from a cDNA library prepared from normal oral tissues, primary oral cancers, and oral cancer cell lines. The genes identified by our microarray(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)
BACKGROUND Annexins are calcium and phospholipid binding proteins that form an evolutionary conserved multigene family. Considerable evidence indicates that annexin A10 (ANXA10) is involved in tumoral progression, although little is known about its role in human oral carcinogenesis. In this study, we investigated the involvement of ANXA10 in oral squamous(More)
BACKGROUND Sindbis virus (SIN) infection causes no or only mild symptoms (fever, rash, and arthralgia) in humans. However, SIN has a strong cytopathic effect (CPE) on various cancer cells. This study focuses on the oncolytic activity of SIN AR399 on oral cancer cells compared with reovirus, a well-known oncolytic virus that targets cancer cells. METHODS(More)
The aim of the present study was to identify a target molecule that could predict the efficacy of radiotherapy in oral squamous cell carcinoma (OSCC). We used DNA microarray analysis to identify differences in gene expression after X-ray irradiation. We compared the gene expression profiles between X-ray (8 Gy)-irradiated Ca9-22 cells (an OSCC-derived cell(More)
MicroRNAs (miRNAs) are small, noncoding RNAs which regulate cell differentiation, proliferation, development, cell cycle, and apoptosis. Expression profiling of miRNAs has been performed and the data show that some miRNAs are upregulated or downregulated in cancer. Several studies suggest that the expression profiles of miRNAs are associated with clinical(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)
