摘要:

目的探讨丹参酮对雄激素剥夺疗法(ADT)诱导的PCa细胞侵袭的影响及其可能的作用机制。我们分别用0 nmol/L(对照组)、5 nmol/L丹参酮处理人PCa LNCaP细胞。分别为(丹参酮组 1)、10 nmol/L(丹参酮组 2)和 20 nmol/L(丹参酮组 3)。分别采用平板克隆实验、管形成实验和Transwell小室实验检测其克隆、血管生成和侵袭能力,采用AnnexinV-FITC/PI双染法检测其凋亡情况,并测定磷脂酰肌醇3-激酶的蛋白表达。 Western blot检测PI3K、p-PI3K、蛋白激酶B(AKT)和p-AKT。与对照组相比,丹参酮1、2、3组的PCa LNCaP细胞克隆出现明显的剂量依赖性下降。形成率([25.14±5.19]% vs [19.33±4.12]% vs [14.69±4.71]% vs [9.35±2.37]%,P<0.05)、细胞腔数([23.20±4.85] vs [19.80±)每个显微视野中的5.12] vs [14.40 ± 4.16] vs [10.20 ± 3.21],P<0.05)和跨膜细胞计数([62.80 ± 8.97] vs [50.40 ± 7.62] vs [38.60 ± 5.16] vs [27.40 ± 4.91] ]每视野,P<0.05),细胞凋亡率增加([3.58±0.74]% vs [8.97±1.36]% vs [14.64±4.10]% vs [21.17±5.37]%,P<0.05) ,下调 p-PI3K、PI3K、p-AKT 和 AKT 的表达(P<0.05)。丹参酮可以逆转 ADT 诱导的 PCa 细胞侵袭,减少其克隆形成和血管生成,促进其凋亡,并抑制PI3K 和 AKT 信号通路的活性。
To explore the effect of tanshinone on the invasion of PCa cells induced by androgen-deprivation therapy (ADT) and its possible action mechanism.We treated human PCa LNCaP cells with tanshinone at 0 nmol/L (the control group), 5 nmol/L (tanshinone group 1), 10 nmol/L (tanshinone group 2) and 20 nmol/L (tanshinone group 3), respectively. Then we detected their cloning, angiogenesis and invasion abilities by plate cloning assay, tube-formation assay and Transwell chamber assay, respectively, examined their apoptosis using the AnnexinV-FITC/PI double staining method, and determined the protein expressions of phosphatidylinositol 3-kinase (PI3K), p-PI3K, protein kinase B (AKT) and p-AKT by Western blot.Compared with the control group, the PCa LNCaP cells in the tanshinone groups 1, 2 and 3 showed significant dose-dependent decreases in the clone formation rate ([25.14 ± 5.19]% vs [19.33 ± 4.12]% vs [14.69 ± 4.71]% vs [9.35 ± 2.37]%, P<0.05), number of cellular lumens ([23.20 ± 4.85] vs [19.80 ± 5.12] vs [14.40 ± 4.16] vs [10.20 ± 3.21] per microscopic field, P<0.05) and count of transmembrane cells ([62.80 ± 8.97] vs [50.40 ± 7.62] vs [38.60 ± 5.16] vs [27.40 ± 4.91] per microscopic field, P<0.05), increase in the rate of cell apoptosis ([3.58 ± 0.74]% vs [8.97 ± 1.36]% vs [14.64 ± 4.10]% vs [21.17 ± 5.37]%, P<0.05), and down-regulation of the expressions of p-PI3K, PI3K, p-AKT and AKT (P<0.05).Tanshinone can reverse ADT-induced invasion of PCa cells, reduce their clone formation and angiogenesis, promote their apoptosis, and inhibit the activity of PI3K and AKT signaling pathways.
