摘要
验证自制DMEM/F12培养基与商品化DMEM/F12培养基相比是否会对奶牛乳腺上皮细胞生物学功能造成负面影响,为进一步研究氨基酸对乳蛋白合成影响及其机理奠定基础。从对奶牛乳腺上皮细胞增殖能力、泌乳相关基因表达和酪蛋白合成这几个方面比较自制DMEM/F12培养基与DMEM/F12培养基的差别。结果显示,自制DMEM/F12培养基对乳腺上皮细胞的增殖活力要显著高于DMEM/F12培养基(P<0.0001);自制DMME/F12培养基与商品化DMEM/F12培养基相比乳腺上皮细胞CSN1S1、CSN3基因表达显著上调(P<0.05),上调量分别达到了3.57倍和3.27倍,CSN1S2、CSN2基因表达量差异不显著(P>0.05);自制DMEM/F12培养基与商品化DMEM/F12培养基相比,对乳腺上皮细胞αS酪蛋白及β-酪蛋白的合成的影响差异并不显著(P>0.05)。由此得出,与商品化DMEM/F12培养基相比,自制DMEM/F12培养基在奶牛乳腺上皮细胞增殖、泌乳相关基因表达和酪蛋白合成方无负面影响。
The purpose of this study was to exam if the self-compounding medium had negative effects on the biological function of bovine mammary epithelial ceils and offered foundation for further experiments.The differences between self-compounding medium and DMEM/F12 medium in this experiment were compared based on determination of cell proliferation, lactating genes expression and casein synthesis. The proliferation of BMEC cultured in self-compounding medium was higher significantly than that of DMEM/F12 medium （ P 〈 0.0001 ） . The CSN1S1 and CSN3 genes expression of BMEC cultured in self-compounding medium increased significantly （ P 〈 0.05 ） and up-regulated 3.57-fold and 3.27-fold, respectively. There were no significance of the CSN1S2, CSN2 gene expression and aS-casein, β-casein synthesis （ P 〉 0.05 ） .Compared with DMEM/F12 medium, self-compounding medium had no negative effects on the lactating genes expression and the casein synthesis, and the further study on effects of different amino acid patterns on lactating genes expression and casein synthesis.
