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:Exosomal and cellular miRNA expression levels were measured using a microRNA chip array or quantitative reverse transcription PCR (qRT-PCR). miR-24-3p was enriched in T-EXOs from the sera of NPC patients and NPC cells, which was correlated with worse disease-free survival (DFS). Exosomes (miR-24-3p-sponge-EXO) released from miR-24-3p-sponge-TW03 cells failed to inhibit T-cell proliferation and Th1 and Th17 differentiation or to induce Treg differentiation in vitro, compared with controlNC -sponge-EXO. Mechanistic analyses revealed that in miR-24-3p-sponge-EXO-treated T-cells, P-ERK, P-STAT1 and P-STAT3 were up-regulated, whereas P-STAT5 was down-regulated compared with controlNC-sponge-EXO-treated T-cells. FGF11 was identified as a direct target gene of miR-24-3p through in vivo and in vitro assessments. More importantly, the T-EXOs repressed FGF11 expression in T-cells during proliferation and differentiation. Interestingly, when FGF11 expression in T-cells was blocked, miR-24-3p-sponge-EXOs impeded shFGF11-T-cell proliferation and Th1 and Th17 differentiation but induced Treg differentiation, like controlNC-sponge-EXO. When FGF11 was knocked down in miR-24-3p-sponge-EXO-treated T-cells, neither P-ERK, P-STAT1 and P-STAT3 up-regulation or P-STAT5 down-regulation occurred. Interestingly, FGF11 expression in tumor-infiltrating lymphocytes (TILs) was significantly and positively correlated with the number of CD4+ and CD8+ TILs and predicted favorable DFS of the patients (p < 0.05). Two-condition experiment, one nasopharyngeal carcinoma cell line TW03 vs. one normal epithelium cell line NP69. Biological replicates: 1 nasopharyngeal carcinoma cell line TW03; 1 nasopharyngeal epithelial cell line NP69.
