摘要: 本研究初步探讨体外黄芩黄素对人食管鳞癌OE33细胞的抑制作用以及可能的作用机制。MTT分析结果表明,黄芩黄素对人食管腺癌OE33细胞具有较强的增殖抑制作用;光学显微镜和激光共聚焦显微镜观察结果表明,黄芩黄素可诱导OE33细胞分化。荧光定量RT-PCR和Western-blot分析结果表明,经80μmol/L黄芩黄素作用后,OE33细胞中hTERT mRNA的表达下降;黄芩黄素诱导14-3-3σ、抑制cyclin B1和cyclin D1的表达,推测此3种基因可能是黄芩黄素实现细胞分化诱导作用的靶基因。

Abstract: Baicalein is a polyphenol compound belonging to the family of flavonoids. The suppressive effect and potential mechanism of baicalein on human esophageal adenocarcinoma cell line (OE33) in vitro were investigated in current work. The results from MTT assay showed that baicalein could greatly inhibit the growth and proliferation of OE33 cells. Baicalein could induce OE33 cell differentiation as determined by phase-contrast microscopy, cofocal laser scanning microscopy, and flow cytometry. The results from real-time RT-PCR and Western-blot analysis showed that baicalein induced the expression of 14-3-3σbut inhibited the expressions of cyclin B1 and cyclin D1. It was suggested that 14-3-3σ, cyclin B1, and cyclin D1 might be the target genes during the differentiation induction by baicalein.

Key words: baicalein, human esophageal adencarcinoma, differentiation, mechanism
