Project description:To identify differentially expressed microRNAs in tumor tissues, human hyopophryngeal squamos cell carcinoma tissues were subjected to miRCURY LNA microRNA Array. A total of 11 pairs of primary hypopharyngeal squamous cell carcinoma samples and adjacent normal mucosa were obtained from patients who underwent tumor resection at Chiba University Hospital (Chiba, Japan). The Ethics Committee of Chiba University approved our study, and informed consent was obtained from all patients for use of their tissue samples and clinical data. The tissue samples were immersed in RNAlater and stored at -20°C until use.

Project description:OBJECTIVE: To investigate the differentially expressed genes and miRNAs related to the chemosensitivity of hypopharyngeal squamous cell carcinoma ï¼HSCCï¼by microarrays and miRNA arrays. METHODS: 1. A total number of 21 patients who underwent induction chemotherapy for primary hypopharyngeal squamous cell carcinoma (12 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. 3. Prediction and analysis of target genes of differentially expressed miRNAs: TargetScan, PITA and microRNAorg methods were used for target gene prediction in GeneSpring 12.5 software, and the intersection of the three methods analysis was considered as significant target genes. Considering the result of microarrays, the intersection of the predicted target genes and the genes screened by microarrays would be analyzed by bioinformatics, which were considered as genes regulated by different miRNAs. RESULTS: 1. Analyzed by microarrays, there were 1579 genes significantly related to the sensitivity to chemotherapy; Among these 1579genes, 815 showed a higher expression in the tissue from patients who are sensitive to chemotherapy , while 764 presented the contrasting pattern. 2. Analyzed by miRNA arrays, there were 24 genes significantly related to the sensitivity to chemotherapy; Among them, 6 showed a higher expression in the tissue from patients who are sensitive to chemotherapy , while 18 presented the contrasting pattern. TargetScan, PITA and microRNAorg were used for target gene prediction in GeneSpring 12.5 software, and the intersection of the three methods analysis was considered as significant target genes. There were 613 putative target genes corresponding to the 24 significant miRNAs. Among them, six genes(MAPK14, ADCY1, GSTM4, CDC42, JUN, GPX6) were statistically and biologically different related to the sensitivity to chemotherapy. And among the 24 significant miRNAs, miR-193b-3pãmiR-211-3pãmiR-4253ãmiR-4496ãmiR-6738-5p could regulate them. CONCLUSIONS: The research revealed a gene expression signature of chemosensitivity in hypopharyngeal squamous cell carcinoma by microarrays and miRNA arrays. The result will contribute to the understanding of the molecular basis of hypopharyngeal squamous cell carcinoma and help to improve diagnosis and treatment. 1.

Project description:To explore the mechanisms underlying the radioresistance of hypopharyngeal carcinoma, we first established specifically radioresistant FaDu cell line (FaDu-RR cells) derived from FaDu cell lines by repeatedly exposing to different doses of ionizing radiation. Then, the aberrantly expressed mRNAs and IncRNAs were detected using microarrays and their bioinformatics were analyzed.

Project description:Background: Clear cell renal cell carcinomas (ccRCCs) display divergent clinical phenotypes. Up to one third of patients with local disease at diagnosis will progress. Therefore, it is a need to identify patients at risk for recurrence. In the present study, we analyzed genome-wide promoter DNA methylation at diagnosis in relation to clinicopathological parameters, in order to identify DNA methylation profiles associated with risk for progress. Method: DNA methylation status in 155,931 CpGs located in gene promoter regions was analyzed by Illumina HumanMethylation450K arrays in diagnostic tissue samples from 115 ccRCC patients. Methylation profiles were compared with genetic aberrations and clinicopathological parameters. Results: The tumors separated into two clusters based on genome-wide promoter methylation status. The tumors in these clusters differed in tumor diameter (p < 0.001), TNM stage (p < 0.001), morphological grade (p < 0.001), and patients outcome (5 year cancer specific survival (pCSS5yr) 72 % in cluster A vs 26 % in cluster B, p < 0.001). When metastasis-status (M0/M1) and cluster A/B status at diagnosis were combined, we found poor survival in M1 patients regardless of cluster A/B status (pCSS5yr 9 % vs 6 %). In M0 patients, the cluster status clearly separated in survival (pCSS5yr 81 % vs 17 %; p < 0.001). We identified a methylation profile of 398 CpGs that was associated with progress of disease, which included differently methylated CpG sites in the SMAD6, SOCS3 and MX2 genes. An integrated genomic and epigenomic analysis revealed significant correlations between the total number of genetic aberrations and hypermethylated CpGs (R = 0.435, p > 0.001), and predicted mitotic age (R = 0.407, p < 0.001). Conclusion: DNA methylation analysis at diagnosis in ccRCC has the potential to improve outcome-prediction and therapy stratification.

Project description:It has been confirmed that nsun2 promotes cell proliferation and migration in hypopharyngeal cancer cell lines, but the pathway of nsun2 in hypopharyngeal cancer cell lines is poorly understood. We constructed stable cell lines by knocking down nsun2 to find the key genes of downstream pathway, and compared them with normal FaDu cell lines.It has been confirmed that nsun2 promotes cell proliferation and migration in FaDu cell line, but the pathway of nsun2 in FaDu cell line is poorly understood.
