Project description:MicroRNAs play a crucial role in tumorigenesis. However, the value of microRNAs in the diagnosis and treatment of tongue squamous cell carcinoma (TSCC) still await investigations. To identify the microRNAs associated with the metastasis of TSCC, we analyzed the transcriptomic difference between metastatic and the non-metastatic TSCC tissue. We identified a set of metastasis-related microRNAs with potential prognostic value.
Project description:To identify differentially expressed genes by anti cancer treatments (microRNAs or siRNAs) in human cancer, several cell lines (pancreatic cancer, esophageal cancer, tongue squamous cell carcinoma, hypopharyngeal squamous cell carcinoma and lung squamous cell carcinoma) were subjected to Agilent whole genome microarrays.
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:We previously found that IGFBP3 mRNA levels are higher in endophytic-type human tongue squamous cell carcinoma (TSCC) that is more invasive and more prone to metastasis than exophytic and superficial types. To investigate the roles of IGFBP-3 in SAS cells that express a fluorescent ubiquitination-based cell-cycle indicator (Fucci).
Project description:Tumor microenvironment (TME) is an active player in malignant growth and spread. Changes in the composition and structure of TME and extracellular matrix can result in either suppression or facilitation of malignant tumor growth. Carcinoma‐associated fibroblasts, bone marrow-derived multipotent mesenchymal stromal cells (BMMSCs), tumor associated macrophages and other inflammatory cells all affect the composition of TME, proliferation and survival of cancer cells, angiogenesis, invasion and metastasis. The objective of this work was to investigate the effect of the interaction between bone marrow-derived BMMSCs and human oral tongue squamous cell carcinoma (OTSCC) cells in the processes of invasion and gene expression. Co-cultures of OTSCC cancer cells and BMMSCs in 3D organotypic invasion assay were used in addition to cell culture, immunological, microarray, and RNA interference techniques. Total number of 4 samples were analyzed. 2 replicates of cultured human oral tongue squamous cell carcinoma (OTSCC) cells, and 2 replicates of OTSCC cells co-cultured with bone marrow-derived multipotent mesenchymal stromal cells
