Abstract:
Objective Signal transducers and activators of transcription 3 (STAT3) silenced by RNA interference (RNAi) technique were used to induce the apoptosis and growth inhibition in T24 and 5637 bladder cancer cells. Methods Three recombinant plasmids pGenesil-1-shRNA-STAT3 was constructed and transfected into T24 and 5637 cells. The expression of STAT3 gene was detected by RT-PCR and Western blotting. FCM was used to observe the apoptosis in T24 and 5637 cells. Results pGenesil-1-shRNA-STAT3 was successfully constructed, and transfected into T24 and 5637 cells. RT-PCR and Western blot analysis demonstrated that pGenesil-1-shRNA-STAT3 could significantly inhibit the expression of STAT3 in T24 and 5637 cells; FCM results show that it could suppress the growth of 1'24 and 5637 cells. Conclusion pGeneSiI-1-shRNA-STAT3 could significantly inhibit STAT3 expression, suppress the growth of T24 and 5637 cells.
