Construction of a hepatocellular carcinoma cell line that stably expresses stathmin with a Ser25 phosphorylation site mutation
We constructed hepatocellular carcinoma (HCC) cells that stably express stathmin with a Ser25 phosphorylation site mutation (stathmin S25A). We used the polymerase chain reaction for site-directed mutagenesis, constructed a stathmin S25A plasmid, and verified the results by restriction enzyme cleavage and sequencing technology. Using the liposome transfection method, stathmin wild-type and S25A HCCLM6 cells were established, which were identified by western blotting.
