Project description:The study aimed to resolve the mechanisms of protective actions of MMP-8 in oral tongue squamous cell carcinoma. The experiment compares the gene expression levels of control and MMP-8 overexpressing human oral tongue squamous cell carcinoma cells (HSC-3) in stationary and migrating phenotype.
Project description:This study aims to compare the global expression signature of protein coding genes between oral cancers from carcinogen-induced mice and human patients. Combinatorial treatment of 4NQO and arecoline for 8 weeks consistently induced the formation of mouse oral cancer with morphology and pathology resembling human oral squamous cell carcinoma. In this dataset, 5 mouse normal tongue and 7 tumor samples were used and Illumina Mouse Ref-8 cDNA microarray was conducted. To identify protein coding genes differentially expressed in mice oral cancers, 7 tumor tissues from carcinogen-treated mice and 5 normal tongue tissues from control mice were used in a microarray-based analysis for protein-coding gene expression patterns.
Project description:DNA methylation profiling of heterogeneous head and neck squamous cell carcinoma (HNSCC) cohorts has been reported to predict patient outcome. We investigated if a prognostic DNA methylation profile could be found in tumour tissue from a single uniform subsite, the oral tongue. The methylation status of 83 comprehensively annotated oral tongue squamous cell carcinoma (OTSCC) formalin-fixed paraffin-embedded (FFPE) samples from a single institution were examined with the Illumina HumanMethylation450K (HM450K) array.

Project description:Transcriptional profiling of squamous cell carcinoma of oral tongue, comparing p53 NS+ and p53 NS- tumors. Goal was to determine differentially expressed genes between them based on global gene expression.
Project description:To investigate the mechanism of artemisinin derivatives in the treatment of oral tongue squamous carcinoma, we treated Cal-27 oral tongue squamous carcinoma cells with artemisinin derivative (DHA) for 48 hours. The results indicated that DHA effectively inhibited the secretion of PDGF-BB by tumor cells, thereby weakening the tumor cells' reprogramming effects on the tumor microenvironment. This finding provides new theoretical support for the anti-tumor mechanisms of natural product derivatives.
