Plants, due to their remarkable composition, are considered as natural resources of bioactive compounds with specific biological activities. Salvia genus (Lamiaceae) has been used around the world in complementary medicine since ancient times. We investigated the cytotoxic, apoptotic and anti-angiogenic effects of methanolic Salvia triloba extract (STE) in prostate cancer cells. Cell viability was evaluated by XTT; apoptosis was investigated by DNA fragmentation and caspase 3/7 activity assays. Changes in the angiogenic cytokine levels were investigated by human angiogenesis antibody array. Scratch assay was used to determine the cell motility. STE induced cytotoxicity and apoptosis in a concentration-dependent manner in both cancer cells; however, it was not cytotoxic to normal cells. Cell motility was reduced in PC-3, DU-145 and HUVEC cells by STE treatment. ANG, ENA-78, bFGF, EGF, IGF-1 and VEGF-D levels were significantly decreased by -2.9, -3.7, -1.7, -1.7, -2.0 and -1.8 fold in STE-treated DU-145 cells, however, ANG, IL-8, LEP, RANTES, TIMP-1, TIMP-2 and VEGF levels were significantly decreased by -5.1, -2.0, -2.4, -3.1, -1.5, -2.0 and -2.5 fold in PC-3 cells. These data suggest that STE might be a promising candidate for anti-tumor and anti-angiogenic treatment of prostate cancer.
由于其独特的成分,植物被视为具有特定生物活性的生物活性化合物的天然资源。鼠尾草属(唇形科)自古以来就在世界各地被用于辅助医学。我们研究了三叶鼠尾草甲醇提取物(STE)对前列腺癌细胞的细胞毒性、凋亡和抗血管生成作用。通过XTT评估细胞活力;通过DNA片段化和半胱天冬酶3/7活性测定研究凋亡。通过人血管生成抗体阵列研究血管生成细胞因子水平的变化。划痕试验用于确定细胞运动性。STE在两种癌细胞中均以浓度依赖性方式诱导细胞毒性和凋亡;然而,它对正常细胞没有细胞毒性。通过STE处理,PC-3、DU-145和HUVEC细胞的细胞运动性降低。在STE处理的DU-145细胞中,ANG、ENA-78、bFGF、EGF、IGF-1和VEGF-D水平分别显著降低了2.9倍、3.7倍、1.7倍、1.7倍、2.0倍和1.8倍;然而,在PC-3细胞中,ANG、IL-8、LEP、RANTES、TIMP-1、TIMP-2和VEGF水平分别显著降低了5.1倍、2.0倍、2.4倍、3.1倍、1.5倍、2.0倍和2.5倍。这些数据表明,STE可能是前列腺癌抗肿瘤和抗血管生成治疗的一个有前景的候选药物。
