摘要: 目的:探讨鹿茸多肽对小鼠胚胎成纤维细胞NIH/3T3增殖和胶原蛋白分泌能力的影响,并阐明其相关作用机制。方法:选取对数生长期的NIH/3T3细胞,加入不同剂量(1.56、3.13、6.25、12.50、25.00、50.00、100.00和200.00 mg·L-1)鹿茸多肽作为实验组,以加入0 mg·L-1鹿茸多肽的细胞作为空白对照组,以加入50μg·L-1碱性成纤维细胞生长因子(bFGF)的细胞作为阳性对照组。MTT法检测各组NIH/3T3细胞存活率,ELISA法检测各组NIH/3T3细胞中胶原蛋白分泌情况,划痕愈合实验检测各组NIH/3T3细胞的迁移能力,Western blotting法检测各组NIH/3T3细胞的细胞外调节蛋白激酶1/2(ERK 1/2)的磷酸化蛋白(p-ERK 1/2)表达水平,免疫荧光法检测转化生长因子β1(TGF-β1)的表达情况。结果:与空白对照组比较,阳性对照组和6.25、12.50、25.00、50.00、100.00及200.00 mg·L-1鹿茸多肽组细胞存活率明显升高(P<0.05或P<0.01)。与空白对照组比较,阳性对照组和6.25、12.50、25.00和50.00mg·L-1鹿茸多肽组NIH/3T3细胞培养液中Ⅰ型胶原蛋白水平明显升高(P<0.05或P<0.01),阳性对照组和12.50及25.00 mg·L-1鹿茸多肽组NIH/3T3细胞培养液中Ⅲ型胶原蛋白水平明显升高(P<0.05)。与空白对照组比较,阳性对照组和12.50mg·L-1鹿茸多肽组细胞划痕愈合率、NIH/3T3细胞中p-ERK 1/2表达水平及NIH/3T3细胞质中TGF-β1表达水平均明显升高(P<0.05或P<0.01)。结论:鹿茸多肽能促进NIH/3T3细胞增殖和胶原蛋白分泌,并提高其迁移能力,其作用机制是可能是通过激活ERK 1/2磷酸化及增加TGF-β1表达实现的。

Abstract: Objective: To investigate the effects of pilose antler polypeptide on the abilities of proliferation and collagen secretion of mouse embryonic fibroblasts NIH/3T3, and to clarify the relevant mechanisms.Methods: The NIH/3T3 cells were treated with different doses(1.56,3.13,6.25,12.50,25.00,50.00,100.00, and 200.00 mg·L-1) of pilose antler polypeptide as experimental groups,the cells treated with 0 mg·L-1 pilose antler polypeptide were used as blank control group, and the cells treated with 50.00 μg·L-1 basic fibroblast growth factor(bFGF) were used as positive control group. MTT assay was used to detect the survival rates of NIH/3T3 cells in various groups. ELISA assay was used to detect the collagen secretion of NIH/3T3 cells in various groups.Wound healing assay was used to detect the migration abilities of NIH/3T3 cells.Western blotting method was performed to detect the expression levels of p-ERK 1/2 in the NIH/3T3 cells in various groups. Immunofluorescence method was used to detect the expression levels of transforming growth factor-β1(TGF-β1) in the NIH/3T3 cells in various groups.Results: Compared with blank control group,the survival rates of NIH/3T3 cells in positive control group and 6.25,12.50,25.00,50.00,100.00,200.00 mg·L-1 pilose antler polypeptide groups were markedly increased (P<0.05 or P<0.01). Compared with blank control group, the levels of type Ⅰ collagen protein in the culture solution of the NIH/3T3 cells in positive control group and 6.25,12.50,25.00,and 50.00 mg·L-1 pilose antler polypeptide groups were markedly increased (P<0.05 or P<0.01), and the levels of type Ⅲ collagen protein in the culture solution of the NIH/3T3 cells in positive control group and 12.50 and 25.00 mg·L-1 pilose antler polypeptide groups were markedly increased (P<0.05). Compared with blank control group,the scratch healing rates of NIH/3T3 cells,and the expression levels of p-ERK 1/2 in the NIH/3T3 cells,and the expression levels of TGF-β1 in the NIH/3T3 cells in positive control group and 12.50 mg·L-1 pilose antler polypeptide groups were markedly increased (P<0.05 or P<0.01).Conclusion: Pilose antler polypeptide can promote the proliferation, and collagen secretion of NIH/3T3 cells and increase the migration ability,which may be achieved by activating the phosphorylation of ERK 1/2 and increasing the expression of TGF-β1.

Key words: pilose antler polypeptide, collagen protein, extracellular signal-regulated kinase, transforming growth factor-β1
