Tetrandrine inhibits human brain glioblastoma multiforme GBM 8401 cancer cell migration and invasion in vitro

Tetrandrine (TET) has been reported to induce anti‐cancer activity in many human cancer cells and also to inhibit cancer cell migration and invasion. However, there are no reports to show TET inhibits cell migration and invasion in human brain glioblastoma multiforme GBM 8401 cells. In this study, we investigated the anti‐metastasis effects of TET on GBM 8401 cells in vitro. Under sub‐lethal concentrations (from 1, 5 up to 10 μM), TET significantly inhibited cell mobility, migration and invasion of GBM 8401 cells that were assayed by wound healing and Transwell assays. Gelatin zymography assay showed that TET inhibited MMP‐2 activity in GBM 8401 cells. Western blotting results indicated that TET inhibited several key metastasis‐related proteins, such as p‐EGFR_(Tyr1068), SOS‐1, GRB2, Ras, p‐AKT_(Ser473) and p‐AKT_(Thr308), NF‐κB‐p65, Snail, E‐cadherin, N‐cadherin, NF‐κB, MMP‐2 and MMP‐9 that were significant reduction at 24 and 48 hours treatment by TET. TET reduced MAPK signaling associated proteins such as p‐JNK1/2 and p‐c‐Jun in GBM 8401 cells. The electrophoretic mobility shift (EMSA) assay was used to investigate NF‐κB and DNA binding was reduced by TET in a dose‐dependently. Based on these findings, we suggested that TET could be used in anti‐metastasis of human brain glioblastoma multiforme GBM 8401 cells in the future.     

miR-31调控PAX9对肺癌细胞增殖和侵袭能力的影响

目的 研究miR-31调控配对盒基因9(PAX9)对肺癌细胞侵袭和增殖能力的影响.方法 运用免疫组织化学检测肺癌组织和癌旁正常组织PAX9蛋白的表达;运用荧光定量PCR检测肺癌组织、癌旁正常组织和肺癌细胞株M14中miR-31的表达.通过转染miR-31-inhibitor下调M14细胞中miR-31的表达,双荧光素酶活性检测miR-31对PAX9转录活性的影响;Transwell侵袭实验检测miR-31对M14细胞的侵袭能力的影响;平板克隆实验检测miR-31对M14细胞的增殖能力的影响.结果 与癌旁正常组织比较,PAX9蛋白在肺癌组织中表达降低,miR-31在肺癌组织中表达明显升高(P<0.05);双荧光素酶活性检测结果显示,miR-31可以直接调控PAX9的转录活性;抑制miR-31的表达后,肺癌细胞株M14的PAX9蛋白表达水平上调,侵袭和转移能力明显降低(P<0.05).结论 miR-31靶向PAX9的表达,从而调控肺癌细胞的侵袭和增殖能力.

Binding and Anticancer Properties of Plumbagin with Human Serum Albumin

Plumbagin has received extensive attention as a promising anticancer drug. Therefore, we investigated the binding and anticancer properties of plumbagin with human serum albumin. Fluorescence results demonstrated that plumbagin interacts with human serum albumin, although its binding affinity may be affected to various extents by different compounds. The human serum albumin–plumbagin complex structure revealed that plumbagin binds to the hydrophobic cavity in the IIA subdomain of human serum albumin through hydrogen bonding and hydrophobic interactions. The plumbagin–human serum albumin complex enhances cytotoxicity by 2‐ to 3‐fold particularly in cancer cells but has no effect on normal cells in vitro. Compared with the unbound drug, the human serum albumin–plumbagin complex promotes HeLa cell apoptosis and has a stronger capacity for cell cycle arrest at the G2/M phase of HeLa cells. In conclusion, this study contributes to the rational design and development of plumbagin‐based drugs and a drug–human serum albumin delivery system.
