ABSTRACT
Objective To study the expression and targeted relationship of miR-103/KLF4 (Krüppel like factor) in A549 and resistant cell lines of lung cancer.Methods To culture the A549 cell lines and A549/DDP (cisplatin) resistant cell lines in vitro and detect survival rates by methyl thiazolyl tetrazolium (MTT) method.Real-time polymerase chain reaction (RT-PCR) and Western blotting were used to test the expression of miR-103/KLF4 of these cell lines.Dual-luciferase reporter gene experiment to detect the targeted relationship.Results A higher expression of miR-103 and a obvious lower expression of KLF4 were observed in A549/DDP resistant cell lines.MiR-103 target KLF4-3'UTR (3'untranslated regions) directly in lung cancer cells.Conclusions In A549/DDP resistant cells,miR-103 can regulate KLF4 at target.
