Objective:To study the effects of oligodeoxynucleotides complementary Stat3 on apoptosis in laryngeal carcinoma Hep-2 cell. Method:Oligodeoxynucleotides complementary Stat3 was designed, which was transferred into laryngeal carcinoma Hep-2 cell by lipofection. Expression of Stat3 and p-Stat3 were detected by Western blot and PCR. MTT was used to observe the growth-inhibiting ratio. DNA ladder, AO/EB and FCM were used to observe the apoptosis of laryngeal carcinoma cell Hep-2 in vitro. Result:Western blot and PCR results demonstrated that oligodeoxynucleotides complementary Stat3 could significantly inhibit the expression of Stat3 and p-Stat3 in Hep-2 cell. MTT results showed that it could significantly suppress the growth of Hep-2 cell. The DNA ladder, AO/EB and FCM results showed it could inhibit the expression of Stat3 and induce the apoptosis of Hep-2 cell in a concentration-dependment manner. Conclusion:Oligodeoxynucleotides complementary Stat3 could induce the apoptosis and suppress cell proliferation in laryngeal carcinoma Hep-2 cell.
