Abstract:
Objective: To construct a hsa-microRNA-224(miR-224) lentiviral expression vector and to establish pancreatic mucinous cystadenocarcinoma MCC1 cell line with stable miR-224 over-expression. Methods: Pri-miR-224 gene fragment was designed and amplified by quantitative real-time polymerase chain reaction (qRT-PCR), and then loaded into GV369 lentiviral vectors (GV369-miR224) by gene recombination technology. GV369-miR-224 lentivrial expression vectors were then identified by PCR and DNA sequencing. The GV369-miR-224 vector fluid was then used to infect pancreatic mucinous cystadenocarcinoma MCC1 cell line to establish the MCC1 cell line stably over-expressing miR-224. The transfection efficiency of GV369-NC and GV369-miR-224 was observed under fluorescence microscopy; and the expression levels of miR-224 in MCC1, GV369-miR-224-MCC1 and GV369-NC-MCC1 cell lines were detected by RT-PCR. Results: The GV369-miR-224 lentiviral vectors were successfully constructed. GV369-miR-224-MCC1 and GV369-NC-MCC1 cells all emit green fluorescence under the fluorescence microscope. The expression level of miR-224 in GV369miR-224-MCC1 cell group was significantly higher than that in negative control GV369-miR-224-MCC1 group and blank control MCC1 cell group (23.45±1.94， 1.46±0.1 and 2.11±0.38, P<0.01), however, there was no significant difference between the two control groups (P>0.05). Conclusion: A pancreatic mucinous cystadenocarcinoma MCC1 cell line with stable miR-224 over-expression was successfully established, and this will provide a new cell model for exploring the function and pathogenesis of miR-224 in pancreatic mucinous cystadenocarcinoma.
