Project description:Despite rapid advances in treatment options, challenges still persist in advanced breast cancer. Bevacizumab is a VEGF-neutralizing antibody with proven efficacy in combination with chemotherapy for treatment of HER2 negative metastatic breast cancer (mBC). Vinorelbine, a semisynthetic vinca alkaloid, is a well-established and well tolerated chemotherapeutic in breast cancer. The combination of vinorelbine with platinum and addition of bevacizumab is relatively underreported in the literature. We propose this combination regimen as safe, well tolerated and efficacious in HER2 negative mBC patients.

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 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: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.

Project description:ObjectiveTo screen out a set of candidate genes which could help to determine whether patients with hypopharyngeal squamous cell carcinoma (HSCC) could benefit from docetaxel, cisplatin and 5-fluorouracil (TPF) induction chemotherapy.MethodsGene-expression profiles in 12 TPF-sensitive patients were compared to 9 resistant controls by microarray analysis. Subsequently, expression levels of potential biomarkers in chemosensitive cell line FaDu after TPF treatment were observed by quantitative real-time polymerase chain reaction (qRT-PCR).ResultsThrough microarray analysis, 1,579 differentially expressed genes were identified, of which 815 were up-regulated in TPF chemotherapy-responsive tissues whereas 764 were down-regulated. Gene ontology (GO) analysis suggested these genes participating in physiological processes including transcription and its regulation, cellular signal transduction and metabolic process. Additionally, Kyoto Encyclopedia of Genes and Genomes (KEGG) database revealed that MAPK and Jat/STAT signaling pathways occupied important roles in TPF chemotherapeutic sensitivity. Moreover, in vitro cell culture experiments revealed the expression alternations of IL-6, MAPK14, JUN, CDK5 and CAMK2A exposed to TPF treatment by qRT-PCR, whilst providing an insight into the mechanism underlying TPF chemotherapeutic response in HSCC.ConclusionsThese results provided a battery of genes related to TPF chemotherapeutic sensitivity and might act as molecular targets in HSCC treatment. Moreover, these candidate biomarkers could contribute to HSCC individualized treatment.
