Objective: To construct eukaryotic expression vector pcDNA3.1-Fat1 and transfect human oral squamous cell
carcinoma cell line Tca8113, then tested the changes of fatty acids content in Tca8113. Methods: The Fat-1 gene was constructed by
SOE-PCR. The pcDNA3.1-Fat1 was constructed by using recombinant DNA technology, human oral squamous carcinoma cells line
Tca8113cells was transfected using lipofection method. The fatty acids content of the transfected Tca8113 cells was detected by using gas
chromatography technology. Results: Eukaryotic expression vector pcDNA3.1-Fat1 was successfully constructed and transfected into
human oral squamous carcinoma cell lineTca8113. The cells that expressed the fat-1 gene had a lower n-6/n-3 PUFA ratio compared with
the cells that expressed the control vector. Conclusion: The pcDNA3.1-Fat1 is successfully constructed, and it has significant effect on the
PUFAs content of Tca8113 cells, which makes a foundation in the future study on the biological function of Fat-1 gene in human oral
squamous carcinoma. |
