ABSTRACT
AIM:
To investigate the effects of eukaryotic vector expressing short hairpin RNA (shRNA) of signal transducers and activators of transcription 3 (STAT3) on the proliferation and apoptosis of SiHa cells.METHODS:
shRNA templates were designed based on STAT3 gene sequence and cloned into pSilencer2.1-U6-neo vector. The resultant plasmid was transfected into SiHa cells with Lipofectamine 2000. The STAT3 protein and mRNA were detected by Western blot and RT-PCR, respectively. The cellular growth activity was assayed by MTT and the apoptosis was tested by flow cytometry.RESULTS:
The plasmid pSilencer2.1-U6-neo-STAT3 was successfully constructed and transfected into SiHa cells. The expression of STAT3 in SiHa cells decreased, the cellular growth activity decreased, and the cell apoptosis increased.CONCLUSION:
The siRNA expressing plasmid pSilencer2.1-U6-neo-STAT3 can inhibit cellular proliferation and induce the apoptosis of cervical cancer cells by suppressing the expression of STAT3.
