ABSTRACT
Objective To figure out and verify infiltration related miRNAs in bladder urothelial carcinoma (BUC). Methods Fresh tissues (20 samples,12 were infiltrative BUC samples,8 were non-infiltrative BUC samples) were collected in liquid nitrogen.The total RNA was extracted by using Trizol reagents.RNA quality control; miRNA microarray hybridization; data analysis.Another 22 samples were collected in fresh (15 were infiltrative BUC samples,7 were non-infiltrative BUC samples) for verifying purpose.4 types of bladder cancer cell lines were used for the study.BUC cell strain; total RNA was extracted by Trizol reagents; RNA quality control; RT-PCR and analysis of the data. Results ①In infiltrative BUC group,compared with non-infiltrative BUC group,there were 7 differentially expressed miRNAshsa-miR29c,hsa-miR-200a,hsa-miR-378,hsa-miR-429,hsa-miR-200c and hsa-miR-141 were up-regulated; hsamiR-451 was down-regulated.②In collected samples,the result of RT-PCR was consistent with miRNA array.③In bladder cancer cell lines,only the results of T24 were consistent with miRNA array. Conclusion Infiltration of BUC might relate with different expression of miRNAs.
