ABSTRACT
Objective:
To explore the influence and regulatory mechanism of TES gene on proliferation and migration of nasopharyngeal squamous cancer(NSPC) 5-8F cell.Method:
DNA fragment encoding TES was obtained by RT-PCR method from the human highly metastatic nasopharyngeal squamous carcinoma cell line 5-8F. we identified the recombinant plasmid pEGFP-N1-TES by RT-PCR and DAN sequencing. we stablely transfected the pEGFP-N1-TES into the human highly metastatic nasopharyngeal squamous carcinoma cell line 5-8F, and detected the expression of TES by the RT-PCR and Western-blot method. And detected the impact of 5-8F cells transfection by flow cytometry and scratch tests.Result:
Flow cytometry analysis showed that the apoptotic in 5-8F/pEGFP- N1-TES was significantly higher than non-transected TES and 5-8F/pEGFP-N1,and the differences were statistically significant(P<0.05).Cell scratch experiments showed that the 5-8F/pEGFP-N1-TES group cell migration rate was obviously lower than nonîtransected TES and 5-8F/pEGFP-N1 group in the first 12 h, 24 h and 48 h.The difference was significant(P<0.01).Conclusion:
The stable transfectant cell model was established successfully. TES in vitro could significantly increase apoptosis and reduce the athletic ability. And thus TES gene might be a novel candidate of tumor-suppressor.Palavras-chave
