Abstract:
OBJECTIVETo observe the in vivo effects of oxysophoridine on hepatocellular carcinoma in mice and to study the related mechanisms.
METHODSC57BL mice were inoculated with mouse hepatoma H22 cells subcutaneously, then divided into 5 groups (14 per group), and treated with oxysophoridine (50, 100, or 150 mg/kg) or cisplatin (4 mg/kg) for 10 days. Inhibitory rate of tumor, body weight gain, and influence indices on internal organs (liver, spleen and thymus) were evaluated. The differentially expressed genes between the oxysophoridine-treated group, and the control group were analyzed using cDNA microarray and quantitative real-time PCR (qRT-PCR) experiments.
RESULTSCompared with the tumor weight of the control group (2.75±0.66 g), oxysophoridine significantly suppressed hepatocellular carcinoma growth in mice (P <0.01), with 0.82±0.36 g, 0.57±0.22 g, and 1.22±0.67 g for the tumor weight in the low, moderate, and high dose treatment group, respectively. The moderate dose led to the highest inhibitory rate, 79.3%. Observation of body weight gain and influence on three organs showed that compared with cisplatin, oxysophoridine produced fewer side effects in vivo. cDNA microarray and qRT-PCR showed that the most significant differentially expressed genes in the tumor samples of oxysophoridine-treated mice were mostly involved in regulating apoptosis, with the Tnfrsf11b (osteoprotegerin) gene being the most significantly affected.
CONCLUSIONOxysophoridine was a promising compound for developing drugs against hepatocellular carcinoma, and its anti-hepatoma effect was probably related to osteoprotegerin activation.
