摘要
目的探讨DHA对神经生长因子NGF诱导PC12细胞的分化作用及其对BMP通路的影响。方法分别用100μg·L-1NGF和100μg·L-1NGF+10μmol·L-1DHA处理PC12细胞,并在3、6、9 d进行免疫荧光染色,观察细胞突起长度和突起数目的变化;气相色谱法分析3、6、9 d NGF+DHA组与NGF组PC12细胞的DHA含量;Western blot法检测NGF+DHA组与NGF组中BMP4、BMP7、BMPR-Ⅱ和pSmad 1/5/8蛋白的表达。结果 NGF+DHA处理组与NGF组相比,突起数目和突起长度明显增多和增长(P<0.01);胞内的DHA含量明显增加(P<0.01);BMP4、BMP7、BMPR-Ⅱ和p-Smad 1/5/8蛋白的表达升高(P<0.05)。结论 DHA能促进NGF诱导的PC12细胞分化,其机制可能与上调BMPs蛋白表达有关。
