ABSTRACT
This study was aimed to investigate the anti-leukemia activity of Tel03 in vivo. The K562 xenografted leukemia model was established and mice were divided randomly into three groups. Mice of different group were treated with PBS (control), 5 mg/kg Tel03 or 15 mg/kg Tel03 (ip, twice a week) respectively. Tumor volume, body weight and other behavior were observed regularly. Cell apoptosis was detected with TUNEL assay and the expression levels of Bcl-2 and Bax were detected by Western blot. The results indicated that Tel03 exerted anti-leukemia activity in mouse model. Tel03 significantly reduced tumor volume in Tel03-treated group compared with control. In addition, 5 mg/kg Tel03 induced cell apoptosis without exerting apparent toxicity in mice. After Tel03 treatment, the expression of Bcl-2 was inhibited, however, the expression of Bax was up-regulated. It is concluded that G-quadruplex ligand Tel03 can induce cell apoptosis in leukemia mouse model, and this agent may be a potential anticancer drug.
