Abstract

In the present study a rat model of oval cell‑mediated liver regeneration was constructed to examine the molecular mechanisms of matrine in oval cell‑mediated liver regeneration and the effects of matrine on hepatic function and the expression of OV6 protein and recombination signal sequence‑binding protein Jκ (RBP‑Jκ) and HES1 mRNA. A total of 48 Sprague Dawley rats were equally and randomly assigned to two groups. The model group underwent oval cell‑mediated liver regeneration, whereas the matrine group underwent oval cell‑mediated liver regeneration and received oral gavage of matrine. Expression of OV6 protein was tested by immunohistochemistry and RBP‑Jκ and HES1 mRNA expression was determined by reverse‑transcription polymerase chain reaction. Recovery of hepatic function was faster in the matrine group compared with the model (P<0.05). OV6 protein, RBP‑Jκ and HES1 mRNA expression levels were lower in the matrine than the model group (P<0.05). Matrine promotes oval cell‑mediated liver regeneration through downregulation of the RBP‑Jκ‑HES1 signaling pathway.

摘要

在本研究中,构建了大鼠卵圆细胞介导的肝再生模型,以研究苦参碱在卵圆细胞介导的肝再生中的分子机制,以及苦参碱对肝功能和 OV6 蛋白、重组信号序列结合蛋白 Jκ (RBP-Jκ) 和 HES1mRNA 表达的影响。将 48 只 Sprague Dawley 大鼠等分为两组。模型组行卵圆细胞介导的肝再生,苦参碱组行卵圆细胞介导的肝再生并给予苦参碱灌胃。采用免疫组织化学法检测 OV6 蛋白表达,逆转录聚合酶链反应法检测 RBP-Jκ 和 HES1mRNA 表达。与模型组相比,苦参碱组肝功能恢复更快(P<0.05)。苦参碱组的 OV6 蛋白、RBP-Jκ 和 HES1mRNA 表达水平低于模型组(P<0.05)。苦参碱通过下调 RBP-Jκ-HES1 信号通路促进卵圆细胞介导的肝再生。
