Objective Two recombinant plasmids , TAZ‐pcDNA3 .1 and TAZ‐pEGFP‐C2 , were established . The protein expression of TAZ in HEK293 cells was detected by Western Blot and the roles of TAZ in promoting cell proliferation and migration were further explored . Methods AZ gene was amplified by PCR , fragments were recovered followed by connection with glue T carrier , blue‐white screening , transformation and extraction of plasmid DNA . Then the plasmid DNA was digested , connected by T 4 DNA Ligase , and then sub‐cloned into pEGFP‐C2 and pcDNA3 .1 to construct new recombinant plasmids . These plasmids were transfected into HEK293 cells to observe the distribution of TAZ using a fluorescence detector . The protein expression was detected by Western Blot .Results By restriction enzyme identification and sequence analysis , the recombinant plasmids were successfully constructed . Fluorescent photos show that the distribution of TAZ molecule was in the nucleus and cytoplasm . Western Blot test results showed that TAZ molecule could induce over‐expression of specific proteins . Conclusion Two recombinant plasmids were successfully constructed . The effects of TAZ over‐expression were validated , which will lay a foundation for revealing the mechanism of TAZ in promoting cell proliferation and migration .
