Momordica charantia has been found to exhibit anticancer activity, in addition to its well-known therapeutic functions. We have demonstrated that the leaf extract of Momordica charantia (MCME) induces apoptosis in several human cancer cells through caspase- and mitochondria-dependent pathways. In this study, a different susceptibility to MCME was found in human lung adenocarcinoma CL1 cells with different metastatic ability, leading to the significant difference of cell viability and invasiveness between MCME-treated CL1-0 and CL1-5 cells. MCME was found to upregulate the expression of Wnt-2 and affect the migratory and invasive ability of CL1 cells through suppressed MMP-2 and MMP-9 enzymatic activities. We proposed that MCME mediates inhibition against migration of CL1 cells by reducing the expression and activation of Src and FAK to decrease the expression of downstream Akt, β-catenin, and MMPs.
苦瓜除了众所周知的治疗功能外,还被发现具有抗癌活性。我们已经证明苦瓜叶提取物(MCME)通过半胱天冬酶和线粒体依赖性途径诱导几种人类癌细胞凋亡。在这项研究中,具有不同转移能力的人肺腺癌细胞 CL1 对 MCME 的敏感性不同,导致 MCME 处理的 CL1-0 和 CL1-5 细胞之间的细胞活力和侵袭性存在显著差异。MCME 被发现上调 Wnt-2 的表达,并通过抑制 MMP-2 和 MMP-9 的酶活性来影响 CL1 细胞的迁移和侵袭能力。我们提出 MCME 通过减少 Src 和 FAK 的表达和激活来降低下游 Akt、β-连环蛋白和 MMPs 的表达,从而介导对 CL1 细胞迁移的抑制。
