    Doxycycline (0.01-10 µg/mL, 4 d) 仅在高浓度下影响胶质瘤细胞的生长[2]。
    Doxycycline (0.01-10 µg/mL, 24 h) 浓度为 1 µg/mL 及更高时降低 SVG 细胞中 MT-CO1 蛋白含量[2]。
    Doxycycline (100 ng/mL, 1 µg/mL; 24 h) 降低人细胞系的增殖[4]。

    体内研究

    诱导基因表达的 ON-OFF 体系[6][7][8]

    致病原理
    Doxycycline 在分子生物学研究中常被用作诱导剂，用于诱导基因表达。在构建了 Tetracycline (Tet; HY-A0107) 诱导表达 (Tet-ON/Tet-OFF) 系统的细胞或模型动物中，可以通过添加或去除 Doxycycline 来精确控制目标基因的表达 ON 和 OFF 的状态。Doxycycline 可以在 Tetracycline (Tc) 控制的反式激活 (tTA) 系统中作为转录激活的抑制剂，又在“反向 tTA‘系统中，作为转录激活的诱导剂。Doxycycline 和 Tetracycline 被上消化道吸收后都是在全身起作用。相比之下，Doxycycline 的主要优点是活性更长，并且可以每天服用两次或一次。虽然两者的峰浓度相似，但 Doxycycline 达到峰浓度的时间更短，半衰期明显更长[6][7][8]。
    具体造模方法
    Rat[8]: male • adult middle-aged (12-month-old) • Sprague-Dawley rats
    Administartion (for GDNF regulation): 3g/kg (Doxycycline; HY-N05655) (dietary with regular food) • po once daily for 6 days • monitored every day
    Note
    1. 该研究[7]中，使用了重组腺相关病毒 (rAAV) 为基础的双顺反子四环素 (tet)-OFF 构建体，用于对 GDNF (目的基因) 长期表达过程中的动态控制。
    2. 3g/kg 膳食 DOX 产生的 DOX 血清水平相当于饮用水中 1mg/ml DOX 的水平。
    造模成功指标
    （1）目的基因表达水平下降；
    （2）与目的基因对应的正相关表型减轻。

    Dosage: 200 or 800 mg/kg
    Administration: Oral gavage; 200 or 800 mg/kg; once daily; 3 months
    Result: Reduced MMP-9 activity in a dose-dependent manner.

    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.
