Project description:Metastasis is the major reason of treatment failure in nasopharyngeal carcinoma. miRNAs have been identified to regulate tumor metastasis. We aimed to identify metastasis-associated miRNAs in nasopharyngeal carcinoma.
Project description:microRNA profiles of exosomes :Exosomes from two nasopharyngeal carcinoma cell line TW03M-oM-<M-^HEBV+M-oM-<M-^Iand TW03M-oM-<M-^HEBV-M-oM-<M-^I and Exosomes from nasopharyngeal epithelial cells NP69 Two-condition experiment, Exosomes from two nasopharyngeal carcinoma cell line vs.one normal epithelium cell line. Biological replicates:1 Exosomes from nasopharyngeal carcinoma cell line TW03M-oM-<M-^HEBV+M-oM-<M-^I, 1 Exosomes from nasopharyngeal carcinoma cell line TW03M-oM-<M-^HEBV-M-oM-<M-^I,1 Exosomes from nasopharyngeal epithelial cells NP69.
Project description:1. To determine the association between LVD and clinico-pathologic variables in archived colorectal cancer and Nasopharyngeal carcinoma specimens
2. To determine the association between VEGF-C,-D expression with COX-2 expression and clinico-pathologic variables in colorectal cancer and Nasopharyngeal carcinoma
3. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma Lymphangiogenesis and factors modulating lymphangiogenesis are associated with clinico-pathological outcome in Nasopharyngeal carcinoma and colorectal cancer. Celecoxib down-regulates lymphangiogenesis Archival colorectal cancer and Nasopharyngeal carcinoma tumor specimens will be obtained from the Department of Pathology. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma, the investigators intend to analyze archived specimens collected in a previously conducted study. Colorectal tumor and nodal specimens and Nasopharyngeal carcinoma primary will be examined for MVD, LVD and growth factor expression using established haematoxylin and eosin and immunohistochemical techniques. Quantification of LVD and MVD shall be performed by two pathologists blinded to clinico-pathological variables using standardised methods.
Project description:The comprehensive DNA methylation analysis with nasopharyngeal carcinoma cases with normal nasopharyngeal epithelial tissues, and nasopharyngeal epithelial cell lines. Infinium HumanMethylation850 BeadChip was used to obtain DNA methylation profiles across 850,000 CpG sites. Samples included 2 nasopharyngeal carcinoma cases, 3 normal nasopharyngeal epithelial tissues, and NP69T and NP69T-LMP1 cell lines.
Project description:microRNA profiles of exosomes :Exosomes from two nasopharyngeal carcinoma cell line TW03（EBV+）and TW03（EBV-） and Exosomes from nasopharyngeal epithelial cells NP69
Project description:We analyzed active enhancers of nasopharyngeal epithelial cell lines and nasopharyngeal carcinoma cell lines by performing ChIP-seq on H3K4me1, H3K4me3, and H3K27ac.
Project description:MicroRNAs are biomarkers of prognosis and survival for many types of cancer. We evaluated whether microRNAs can predict the survival and efficacy of concurrent chemotherapy in nasopharyngeal carcinoma (NPC) patients. We retrospectively analyzed microRNA expression in 312 paraffin-embedded NPC specimens and 18 normal nasopharyngeal tissues using microarray. We found Forty-one microRNAs are differentially expressed between NPC and normal tissues, and a five-microRNA signature can predict survival independent of stage. NPC patients with the low-risk microRNA signature have a favorable response to concurrent chemotherapy. microRNA profiling of nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues 312 paraffin-embedded nasopharyngeal carcinoma tissues and 18 paraffin-embedded normal nasopharyngeal tissues
