摘要:

目的 探讨毛兰素对乳腺癌细胞的增殖、迁移、侵袭和凋亡的影响及潜在的分子机制。 方法 分别用0、12.5、25、50、100 nmol/L毛兰素处理乳腺癌细胞系T-47D和MCF-7,采用CCK-8法检测12、24、36、48、72 h的细胞活力;克隆形成、细胞划痕、Transwell侵袭和细胞衰老实验分别检测毛兰素对T-47D和MCF-7细胞增殖、迁移、侵袭能力以及细胞衰老的影响。通过毛兰素mRNA微阵列以及Enrichr数据库探索毛兰素的生物学功能。通过流式细胞术检测不同浓度毛兰素对T-47D和MCF-7细胞凋亡率的影响。通过Western blotting检测细胞凋亡、上皮-间充质转化(EMT)以及Wnt/β-catenin通路相关蛋白的表达情况。 结果 毛兰素呈浓度依赖性抑制T-47D和MCF-7细胞活力、增殖、迁移与侵袭能力,并促进细胞衰老(P<0.05)。毛兰素相关mRNA微阵列分析结果显示,共有1064个差异表达基因(DEGs)(P<0.05),其中948个表达上调基因,116个表达下调基因。GO富集分析结果显示,毛兰素的DEGs主要富集在EMT的调节、含胶原蛋白的细胞外基质及钙离子结合等功能中;KEGG和WikiPathways富集分析结果显示,毛兰素可能通过调节PI3K-Akt信号通路、Wnt/β-catenin信号通路以及细胞凋亡影响乳腺癌的发生与进展。流式细胞术结果显示,毛兰素呈浓度依赖性诱导乳腺癌细胞凋亡(P<0.05)。Western blotting结果显示,随着毛兰素浓度升高,促凋亡蛋白Bax、Caspase3表达上升,而抗凋亡蛋白Bcl-2表达下降(P<0.05);EMT相关蛋白Snail、N-cadherin、β-catenin表达下降(P<0.05);Wnt/β-catenin信号相关蛋白TCF4、Cyclin D1、c-Myc表达下降(P<0.05);与100 nmol/L毛兰素组相比,100 nmol/L毛兰素+Wnt/β-catenin激动剂组TCF4、Cyclin D1、c-Myc表达增加(P<0.05)。 结论 毛兰素能抑制乳腺癌细胞增殖、迁移和侵袭,并诱导细胞衰老和凋亡,其分子机制可能与阻断Wnt/β-catenin信号通路,协同诱导细胞凋亡并逆转EMT过程有关。

Abstract:

Objective To investigate the effect of erianin on proliferation, migration, invasion, and apoptosis of breast cancer cells and the underlying mechanisms. Methods Breast cancer cell lines T-47D and MCF-7 treated with 0, 12.5, 25, 50, and 100 nmol/L erianin for 12, 24, 36, 48, and 72 h were examined for cell viability using CCK-8 assay. The effects of erianin on cell proliferation, migration, invasion, senescence and apoptosis were evaluated using clone formation, wound healing, Transwell invasion, and senescence assays and flow cytometry. mRNA microarray analysis and the Enrichr database were used to explore the biological functions of erianin. Western blotting was used to detect the changes in protein expressions related to apoptosis, epithelial-mesenchymal transition (EMT), and the Wnt/β-catenin pathway. Results Erianin concentration-dependently inhibited cell viability, proliferation, migration, and invasion, and promoted senescence in T-47D and MCF-7 cells. Microarray analysis identified 1064 differentially expressed genes (DEGs), including 948 upregulated and 116 downregulated genes, which were involved primarily in EMT regulation, collagen-containing extracellular matrix, calcium ion binding, the PI3K-Akt signaling pathway, the Wnt/β-catenin signaling pathway, and apoptosis. Flow cytometry confirmed that erianin concentration-dependently induced apoptosis in the breast cancer cells, upregulated the expressions of Bax and caspase-3, decreased Bcl-2 expression, and lowered the expressions of EMT-related proteins (Snail, N-cadherin, and β‑catenin) and Wnt/β‑catenin signaling proteins (TCF4, Cyclin D1, and c-Myc). In the breast cancer cells treated with 100 nmol/L erianin, the application of a Wnt/β‑catenin agonist significantly increased the proteins expressions of TCF4, Cyclin D1, and c-Myc. Conclusion Erianin inhibits proliferation, migration, and invasion and induces senescence and apoptosis in breast cancer cells possibly by suppressing the Wnt/β-catenin signaling pathway to induce cell apoptosis and reverse EMT of the cells.
