چکیده
Objectives: The aim of this study was to examine the effect of flaxseed on gene expression of intestinal transporters: Niemann-Pick C۱ like ۱ (NPC۱L۱), ATP-cassette binding proteins G۵ (ABCG۵) and G۸ (ABCG۸). Methods: Animals were randomly divided into ۳ groups ۸ rats in each group: group۱; normal diet, group۲; diabetic rats, and group۳; diabetic rats + ۴% (w/w) flaxseed. After one-month rats were sacrificed, blood was collected; lipid profiles were determined enzymatically, and mRNA levels were deter-mined by RT-PCR. Results: Compared to diabetic rats, flaxseed significantly decreased total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides, very low density lipoprotein cholesterol (VLDL-C) and atherogenic index (all P< ۰.۰۵). Intestinal NPC۱L۱ mRNA was significantly decreased (P< ۰.۰۱) in flaxseed group treatment compared with diabetic animals. Intestinal ABCG۵ and ABCG۸ mRNAs were significantly increased (P< ۰.۰۰۱) in flaxseed group treatment compared with diabetic animals. Conclusion: In conclusion, flaxseed significantly reduced lipid profile and atherogenic index, as compared with the diabetic group. Flaxseed treatment also led to down-regulation of NPC۱L۱ mRNA and up-regulation of ABCG۵ and ABCG۸ mRNAs in the intestine of rats.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
