[Mitochondrial mechanisms of antisense oligodeoxynucleotide Stat3 induced apoptosis in laryngeal carcinoma cell].

To investigate the changes of mitochondrion by transferring antisense oligodeoxynucleotide Stat3 into laryngeal carcinoma Hep-2 cell, for elucidating the mechanism of laryngeal carcinoma Hep-2 cell apoptosis, for developing more effective treatment for laryngeal cancer.The designed Stat3 ASODN was transferred into laryngeal carcinoma Hep-2 cell by lipofection. Mitochondrion membrane potential, VDAC and Cyt-c were detected for determining the changes of mitochondrion.MMP was fell, Cyt-c and VDAC were increased with the heighten concentration of ASODN.Mitochondria approach play an important role in the apoptosis mechanism of human Hep-2 cell by Stat3. This research elucidated the regulating mechanism of Hep-2 cell proliferation by Stat3, provided a new research focus for clinical therapy.
