| Abstract | Aim of study: This study aimed to elucidate and compare the anti-metastatic mechanism of Tian-Xian liquid (TXL) and its bioactive components namely butanol (BU), ethyl-acetate (EA) and aqueous (WA) fractions on human colorectal cancer in vitro (HT-29 cancer cells) and in vivo (nude mouse xenografts). Materials and methods: The anti-proliferative effects of TXL and its bioactive components in HT-29 cells were determined by MTT assay. Their modulations on the potential angiogenic and metastatic marker expressions on HT-29 cells and xenografts were investigated by real-time PCR and Western blot at transcriptional and translational levels, respectively. For the in vitro study, migration abilities of HT-29 cells were determined using wound healing assay. For the in vivo study, daily measurements of the tumor size and volume of the xenografts were also performed. Results: TXL, BU, EA and WA effectively inhibited the proliferation of HT-29 cells in a dose- and time-dependent manner. The IC 50 value of TXL on HT-29 cells was obtained after incubation with 1% (v/v) TXL for 4 h; whereas IC 50 values were obtained for the following bioactive components: BU at 1.25% (v/v); EA at 5% (v/v); and WA at 0.3125% (v/v). It was found that 1% (v/v) TXL significantly down-regulated MMP2 and MMP7 expression at both transcriptional and translational levels and it reduced MMP9 and VEGF protein expression in vitro. TXL decreased the metastatic ability of HT-29 cells as demonstrated by wound healing assay. TXL and its bioactive fractions caused no significant changes in the body weight indicating lack of toxicity to the xenografts. Conclusions: In summary, TXL multi-targeted to down-regulate the metastatic markers in both in vitro and in vivo models. However, the effects of its bioactive fractions were not obvious. This study profoundly elucidated the anti-proliferative mechanism of TXL, which is vital for the development of future anti-cancer regime in Chinese medicinal formulations. © 2011 Elsevier Ireland Ltd All rights reserved. | ||||||
