Figure 2From: Spica prunellae promotes cancer cell apoptosis, inhibits cell proliferation and tumor angiogenesis in a mouse model of colorectal cancer via suppression of stat3 pathway Effect of EESP on tumor growth in colorectal cancer (CRC) xenograft mice and HT-29 colon cancer cells. After tumor development, the mice were given intra-gastric administration of 6Â g/kg/d dose of EESP or saline daily, 5Â days per week for 16Â days. Tumor volume (A), tumor weight (B) and body weight (C) were was measured at the end of experiment. (D) HT-29 cell viability was determined by the MTT assay after cells were treated with the indicated concentrations of EESP for 24Â h. The data were normalized to the viability or survival of control cells (100%, treated with 0.5% DMSO vehicle). Data shown are averages with S.D. (error bars) from 9 individual mice in each group or from three independent cell-based experiments. *P< 0.01, versus controls.Back to article page
