Salvia clandestina L. is a wild perennial species present in the Salento area of Italy. Here, we examined the in vitro effects of an aqueous extract of S. clandestina L. on the MG-63 osteosarcoma cell line. The extract reduced osteosarcoma cell viability mainly by way of apoptosis, as we observed (1) upregulation of gene and protein expression of p53, cyclin-dependent kinase inhibitors p21WAF1 and p27Kip1, and proapoptotic BAX; (2) activation of caspases; and (3) induction of a sub-G1 peak in the cell cycle. The mitogen-activated protein kinases (MAPKs) JNK1/2 and p38 are activated and involved in the intracellular effects of the S. clandestina extract, as preincubation with the JNK1/2 inhibitor SP600125 or the p38 inhibitor SB203580 significantly decreased S. clandestina extract–induced cytotoxicity and inhibited increase in p53, p21WAF1, p27Kip1, and BAX. SP600125 also inhibited mRNA levels for all the aforementioned proteins, while SB203580 only affected p53 mRNA. Furthermore, S. clandestina extract treatment counteracted epithelial-to-mesenchymal transition, inhibited cell migration, and decreased the expression and activity of matrix metalloproteinase MMP2. In addition, S. clandestina extract enhanced the cytotoxic activity of cisplatin on MG-63 cells through downregulation of the Akt/PKB protein kinase. We conclude that S. clandestina extract may be a novel agent for osteosarcoma treatment.

丹参提取物对骨肉瘤细胞的抗肿瘤和抗迁移作用

Salvia clandestina L. 是一种存在于意大利萨兰托地区的多年生野生物种。在这里,我们检查了S. cldestina L.的水提取物对 MG-63 骨肉瘤细胞系的体外作用。提取物主要通过细胞凋亡降低骨肉瘤细胞活力,因为我们观察到 (1) p53、细胞周期蛋白依赖性激酶抑制剂 p21 WAF1和 p27 Kip1以及促凋亡 BAX的基因和蛋白质表达上调;(2)半胱天冬酶的活化;(3)在细胞周期中诱导亚G 1峰。丝裂原活化蛋白激酶(MAPK)JNK1 / 2和p38被激活,参与的细胞内效应S. clandestina提取物,因为与 JNK1/2 抑制剂 SP600125 或 p38 抑制剂 SB203580 预温育显着降低了秘密链球菌提取物诱导的细胞毒性,并抑制了 p53、p21 WAF1、p27 Kip1和 BAX 的增加。SP600125 还抑制所有上述蛋白质的 mRNA 水平,而 SB203580 仅影响 p53 mRNA。此外,S.clandestina提取物处理抵消了上皮-间质转化,抑制了细胞迁移,并降低了基质金属蛋白酶 MMP2 的表达和活性。此外,秘密链球菌提取物通过下调 Akt/PKB 蛋白激酶,增强了顺铂对 MG-63 细胞的细胞毒活性。我们得出的结论是S. cldestina提取物可能是治疗骨肉瘤的新型药物。
