Nasopharyngeal carcinoma (NPC) at present is considered to be one of the fatal diseases detected commonly in the people belonging to Southeast Asia and southern China. According to the WHO reports among the detected cases of NPC worldwide, 80% are from China. The present study investigates the effect of tanshinone IIA on the migration and invasion potential of HNE-1NPC cells and studied the detailed mechanism involved. Effect of the tanshinone IIA on viability of the HNE-1NPC cells was analyzed by MTS assay. Cell matrigel invasion and wound-healing motility assays, respectively were used for the analysis of invasion and migration potential of HNE-1 cells. Tanshinone IIA inhibited the viability of HNE-1cells in a dose dependent manner. Migration and invasion potential of the tanshinone IIA treated cells was reduced significantly ( < 0.05) compared to the control cells after 48 h. Analysis of the proteins involved in migration and invasion revealed a significant decrease in the expression of matrix metalloproteinase (MMP)-2 and MMP-9 on treatment with tanshinone IIA. It also inhibited the p65 and p50 expression in the nuclear fractions of HNE-1 cells after 48 h. Thus, tanshinone IIA inhibits migration and invasion potential of the HNE-1NPC cells through reduction in the expression of matrix metalloproteinases. Therefore, tanshinone IIA can be used for the treatment of NPC.
鼻咽癌(NPC)目前被认为是在东南亚和中国南方人群中常见的致命疾病之一。根据世界卫生组织的报告,全球检测到的鼻咽癌病例中,80%来自中国。本研究调查了丹参酮IIA对HNE-1NPC细胞迁移和侵袭能力的影响,并研究了其中涉及的详细机制。通过MTS试验分析丹参酮IIA对HNE-1NPC细胞活力的影响。分别使用细胞基质胶侵袭试验和伤口愈合运动试验分析HNE-1细胞的侵袭和迁移能力。丹参酮IIA以剂量依赖性方式抑制HNE-1细胞的活力。与对照细胞相比,48小时后丹参酮IIA处理的细胞的迁移和侵袭能力显著降低(<0.05)。对参与迁移和侵袭的蛋白质分析显示,用丹参酮IIA处理后,基质金属蛋白酶(MMP)-2和MMP-9的表达显著降低。48小时后,它还抑制了HNE-1细胞核组分中p
65和p50的表达。因此,丹参酮IIA通过降低基质金属蛋白酶的表达来抑制HNE-1NPC细胞的迁移和侵袭能力。因此,丹参酮IIA可用于治疗鼻咽癌。
