Project description:Investigation of whole genome gene expression level changes in laryngeal squamous carcinoma cell line TU177 in response to overexpressed miR-145-5p. Differentially expressed protein-coding genes in the human laryngeal squamous carcinoma cells TU177 overexpressing miR-145-5p were identified by microarray analysis.

Project description:OBJECTIVE: To investigate the differentially expressed genes related to the chemosensitivity of laryngeal squamous cell carcinoma （LSCC）by microarrays arrays. METHODS: 1. A total number of 11 patients who underwent induction chemotherapy for primary hypopharyngeal squamous cell carcinoma (7 patients are sensitive to chemotherapy ,and others are not) were recruited for microarray and miRNA array gene expression analysis 2. Bioinformatics analysis of differentially expressed genes screened by microarrays : The differential gene cluster analysis was applied in biological processes, cellular components and molecular functions by GO database; The differential gene enrichment analysis was applied in signaling pathways by KEGG database, and the differentially expressed and biologically meaningful core genes would be screened. RESULTS: 1. Analyzed by microarrays, there were 1554 genes significantly related to the sensitivity to chemotherapy; Among these 1554genes, 777 showed a higher expression in the tissue from patients who are sensitive to chemotherapy , while 785 presented the contrasting pattern. CONCLUSIONS: The research revealed a gene expression signature of chemosensitivity in laryngeal squamous cell carcinoma by microarrays arrays. The result will contribute to the understanding of the molecular basis of laryngeal squamous cell carcinoma and help to improve diagnosis and treatment.

Project description:To understanding the miRNA expression profiling of cancer stem cells of laryngeal squamous carcinoma, the total RNA of CD133+CD44+ laryngeal cancer stem cells (isolated from LSCC cell line TU-177, named TDP), CD133-CD44- cells (TDN) and parental TU-177 (unsorted TU-177 cells, named TPT) was extracted, followed by miRNA sequencing. Differentially expressed miRNAs were identified.

Project description:Cancer of the larynx is the second most common upper-aerodigestive cancer, and laryngeal squamous cell carcinoma (LSCC) is the major histological form. However, the molecular mechanism within LSCC progression remains poorly understood. MicroRNA-based target therapy is a promising approach in cancer therapy and offers multiple advantages as compared with the conventional treatment modalities. Hence, there is a need to identify the key microRNA involved in the progression of LSCC. We used GeneChip miRNA 2.0 array to profile the global microRNA deregulation in LSCC.

Project description:Laryngeal squamous cell carcinoma (LSCC) is a common form of head and neck cancer with poor prognosis. The spindle and kinetochore associated complex subunit 3 (SKA3) protein was upregulated in LSCC and associated with poor prognosis. To understand mechanism of SKA3 regulation in LSCC, we performed high throughout transcriptome sequencing to identify SKA3-regulated genes.

Project description:Objective: The purpose of this study was to investigate the miRNAs basis of tumorigenesis in LSCC, and analyze the physiological processes of target genes predicted by the screened miRNAs that may be useful for the effective therapeutic strategies. Methods: A total number of 6 patients who underwent surgery for primary laryngeal squamous cell carcinoma were recruited for miRNA array analysis. LSCC tissues compared with corresponding adjacent non-neoplastic tissues were analysed by the Affymetrix GeneChip miRNA Array 3.0 to screen effective miRNAs, then TargetScan,PITA and microRNAorg were used for target gene prediction in GeneSpring 12.5 software.Moreover, pathway-based methods were adopted to analyse physiological processes of the target genes. The screened miRNAs and the significant target genes were also validated by qRT-PCR in another 36 patients diagnosed for LSCC. Results: Analysed by the miRNAs arrays, there were seven miRNAs (hsa-miR-224, hsa-miR-183, hsa-miR-23a, hsa-miR-675, hsa-miR-27a, hsa-miR-503 and hsa-miR-4800-3p) significantly related to tumorigenesis ,and all the screened miRNAs in laryngeal squamous cell carcinoma tissues were significantly up-regulated(P<0.05). The expressions of these miRNAs were also validated by qRT-PCR. Then analysed by GeneSpring 12.5 software, there were 72 putative target genes corresponding to the seven significant miRNAs. Moreover,analysed by String database,the result indicated that most target genes could be composed of gene networks; Analysed by GO database, we observed that these target genes were involved in processes such as metabolic process, biological regulation,membrane,protein binding,ion binding and so on (P <0.05); Analysed by KEGG pathways database, MAPK signaling pathway, adherens junction and pathways in cancer played especially important role in tumorigenesis of LSCC (P<0.05). As the two important genes in MAPK signaling pathway which plays pivotal roles in tumorigenesis, FGF2 and MAP2K4 were validated by qRT-PCR, and they were significantly down-regulated(P<0.05). Conclusions: The research revealed seven miRNAs expression signature(hsa-miR-224, hsa-miR-183, hsa-miR-23a, hsa-miR-675, hsa-miR-27a, hsa-miR-503 and hsa-miR-4800-3p) of tumorigenesis in laryngeal squamous cell carcinoma,and analysed the physiological processes of the predicted target genes regulated by screened miRNAs in LSCC. The result will contribute to the understanding of the molecular basis of LSCC and help to improve the treatment.
