The Lenti-shRNA vector system (pGV112) was constructed, packed, purified by GeneChem (Shanghai, China), and manipulated according to the protocol provided by the manufacturer. Then, transfection was performed using Lipofectamine 2000 following the manufacturer’s instructions.
To identify the transfection efficiency, SiHa and HeLa cells were transfected with lentivirus plasmids (sh-DGKZ or sh-NC). 48 h post transfection, DGKZ expression was observed using inverted fluorescence microscope (OLYMPUS, Japan).
