    体外研究
    (In Vitro)

    Neferine down regulates hypoxia induced NF-κB p65 nuclear translocation and COX-2 expressions[1]. Neferine reduces high-glucose-induced collagen production and inhibits TGF-β1-Smad, ERK and p38 MAPK signaling activation in cardiac fibroblasts. Cardiac fibroblasts (CFs) are cultured in HG medium with varying concentrations of Neferine (1, 2, or 5 μM). CCK-8 assays are carried out at different time points (24, 48, and 72 h). Compared with normal glucose (NG) and osmotic control (OC) treatments, High glucose (30 mM) treatment significantly increases the proliferation of CFs in a time-dependent manner (P<0.05). High glucose (HG)-induced CF proliferation is markedly attenuated by Neferine treatment at either 2 or 5 μM compared with vehicle treatment. However, 1 μM Neferine does not inhibit HG-induced proliferation of CFs. Therefore, 2 and 5 μM Neferine are used in the remaining experiments[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Neferine treatment at both low-dose (60 mg/kg/day by gavage) and high-dose (120 mg/kg/day by gavage) reduces the increment of collagen I, III and TGF-β1 protein expression induced by hyperglycemia[2].

    动物实验：

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：
    ——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

    • 方案 一

      请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.08 mg/mL (3.33 mM); 澄清溶液

      此方案可获得 ≥ 2.08 mg/mL（饱和度未知）的澄清溶液。

      以 1 mL 工作液为例，取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。

      生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。
    • 方案 二

    Cell Assay
    [2]

    Cardiac fibroblasts (CFs) are isolated from neonatal mouse ventricular tissues. After starvation in serum-free medium for 24 h, CFs are incubated in DMEM containing 5.6 mM glucose (normal glucose; NG), 30 mM D-glucose (HG), 30 mM D-glucose plus 1 μM Neferine, 30 mM D-glucose plus 2 μM Neferine, 30 mM D-glucose plus 5 μM Neferine, and 5.6 mM glucose plus 27.5 mM mannose. Cells are harvested at 24 h, 48 h, and 72h. Cell proliferation is measured with the Cell Counting Kit-8 (CCK-8) and the Cell-LightTM EdU assay[2].

    Animal Administration
    [2]

    Mice[2]
    Eight-week-old C57BL/6J male mice are used. Diabetes is induced by intraperitoneal injection of Streptozotocin dissolved in citrate buffer (pH 4.5) at 60 mg/kg body weight for five consecutive days. Control mice are injected with citrate buffer only. Whole blood glucose in mouse tail blood is detected with an Accu-Check Active glucometer. Mice with blood glucose concentrations higher than 18 mM are considered as diabetic animals and used in this study. The animals are randomly divided into four groups of eight animals each. Diabetic mice are divided into three groups: group 1, the diabetic control group (DM); group 2, which receive Neferine at a dose of 60 mg/kg/day (DM-NL); and group 3, which receive Neferine at a dose of 120 mg/kg/day (DM-NH). Neferine is administered twice per day by intragastric gavage for 12 weeks. Equivalent volumes of normal sodium are administered to the normal and DM control groups by gavage. Mice are anaesthetized and sacrificed at the end of the 12-week treatment[2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
