中文摘要:目的: 探讨河蚌肉提取物葡聚糖HBP-A(anodonta glucan HBP-A)对体外软骨细胞Wnt通路的调控作用。方法: 体外培养大鼠软骨细胞,添加IL-1β(10 ng/ml)诱导分化,分为空白组,IL-1β组,IL-1β+IWP-2(5 μM,Wnt通路抑制剂)组,IL-1β+ HBP-A(0.3 mg/ml)组,IL-1β+IWP-2 +HBP-A共5组培养,提取各组细胞RNA和蛋白,采用Rt-PCR检测各组细胞Wnt-3a、β-catenin(24、48、72 h)及MMP-13(72 h)的基因表达;采用Western-blot检测β-catenin、MMP-13、Sox-9和Coll-Ⅱ蛋白的表达水平(48 h).结果: 细胞经IL-1β诱导分化,Wnt-3a基因表达升高,β-catenin以及MMP-13基因和蛋白表达升高,Sox-9和Coll-Ⅱ蛋白表达下调。添加HBP-A干预可以抑制 IL-1β诱导下软骨细胞Wnt-3a基因的高表达、β-catenin以及MMP-13基因和蛋白的高表达,上调Sox-9和Ⅱ型胶原蛋白的表达。IWP-2和HBP-A合用时,Wnt-3a、β-catenin基因以及β-catenin蛋白表达最低,Sox-9蛋白表达最高。结论: HBP-A可通过降低Wnt/β-catenin信号通路表达,延缓软骨细胞分化,并且可与Wnt抑制剂协同调节Wnt-3a、β-catenin和Sox-9因子的表达。

Regulating effect of anodonta glucan HBP-A on chondrocytes through Wnt pathway
ABSTRACT  Objective: To investigate regulation function of anodonta glucan HBP-A on chondrocytes through Wnt pathway in vitro. Methods: Rat chondrocytes were cultured and differentiated induced with IL-1β(10 ng/ml) in vitro. Chondrocytes were divided into five groups:IL-1βgroup,IL-1β+IWP-2(5 μM,Wnt pathway inhibitor) group,IL-1β+ HBP-A (0.3 mg/ml) group and IL-1β+IWP-2 +HBP-A group. Wnt-3a,β-catenin (24 h,48 h,72 h) and MMP-13(72 h) genes expression were detected by Rt-PCR,while β-catenin,MMP-13,Sox-9 and coll-Ⅱ(48 h) protein expression were measured by Western-blot. Results: After induction of IL-1β,gene expression of Wnt-3a,β-catenin and MMP-13 were increased,so were the protein expression of β-catenin and MMP-13. In contrast,protein expression of Sox-9 and Coll-Ⅱ were declined. Following addition of HBP-A,Wnt-3a,β-catenin and MMP-13 were shown as induction of IL-1β,but protein expression of Sox-9 and Coll-Ⅱ were upgraded. Combining HBP-A with IWP-2 led to the lowest level in Wnt-3a,β-catenin gene and β-catenin protein expression and highest expression of Sox-9 protein. Conclusion: HBP-A could not only delay the differentiation of chondrocytes through downgrading the signal expression of Wnt/β-catenin,but also adjust the expression of Wnt-3a,β-catenin and Sox-9 when combinated with the Wnt inhibitor.
