MMP

[体外研究]

强力霉素在体外对鸡毒支原体菌株S6显示出优异的有效性和时间依赖性[2]。与对照成骨细胞培养物相比,在所有实验时间点,暴露于含有25μg/ mL多西环素(DOX)/β-环糊精(βCD)的复合物的成骨细胞具有增加的细胞增殖(p <0.05),在第二周达到最大值。暴露于DOX /βCD复合物的成骨细胞中碱性磷酸酶(AP)活性和胶原分泌水平也升高(与对照相比p <0.05),14天后达到最大值[3]。强力霉素(20 nM)抑制SMC(平滑肌细胞)类型培养物中ECM(细胞外基质)的产生和重塑,SMC-Ch(富含胆固醇的饮食)中胶原蛋白和异戊二烯化蛋白的合成高于SMC -C(标准饮食)[4]。

[体内研究]

在杂合(HT)Col3a1敲除小鼠中,在用强力霉素或安慰剂治疗3个月后,对9个月大的HT或野生型(WT)小鼠进行主动脉的外科应力。干预后1周未治疗的HT小鼠中应力诱导的主动脉病变增加3倍(累积评分4.5±0.87对比WT中的1.3±0.34,p <0.001)在强力霉素中完全预防(25或100 mg/kg) ,po)-处理组(1.1±0.56)[1]。

[激酶实验]

将明胶（0.1％（w / v））加入到标准LaemmLi丙烯酰胺聚合混合物中。将组织提取物与样品缓冲液[250mM Tris-Cl pH 6.8,10％（w / v）SDS，20％（v）1：2混合。 / v）甘油，0.005％（w / v）溴酚蓝]。血清用电泳缓冲液（2.5mM Tris，20mM甘氨酸，0.005％SDS）1:10稀释，并与样品缓冲液1：2混合。二十μL是在室温下孵育10分钟而不煮沸。在90V电泳后，将凝胶浸泡在2.5％（w / v）Triton X-100中，在37℃下在明胶消化缓冲液中孵育2至3天[50] mM Tris-Cl，pH 8.0,8mM CaCl 2,10mM ZnSO 2,0.02％（w / v）NaN 3]，在0.05％考马斯蓝R-250的乙酸/甲醇/水（体积比1：4.5：4.5）中染色），在10％乙酸和5％甲醇中脱色，扫描裂解带强度。裂解带强度与明胶酶活性成正比，并用一维扫描软件进行光密度定量。结果，数值在0.07和3.75之间，没有通过将光密度测定结果与来自BCA蛋白质测定试剂盒结果的相对光密度分开，使蛋白质含量变得均匀。结果用作任意单位的分析。对于MMP-9的裂解条带的总MMP活性结果，加入活性MMP-9，pro-MMP-2和活性MMP-2。蛋白质大小标记用于确定正确的大小。

[细胞实验]

当SMC中的ECM合成开始明显时，所有体外处理在SMC培养物中以90％汇合进行。将多西环素（20 nM）稀释于培养基中，浓度为10μg/ mL（20 nM），此时未报告原代培养的SMC增殖的毒性或变异，以及其他细胞系，培养时间为48小时将SMC-C和SMC-Ch以相同的细胞密度接种在6孔板中，当汇合度达到90％时，向每个含有3.7×104 Bq L- [5-H3] - 脯氨酸的孔中加入1mL培养基（ 9.62×1011 Bq / mmol）。温育48小时后，将细胞用0.5mL 0.5mol / L NaOH裂解1小时。用等量的0.5mol / L HCl中和所得溶液，用Bradford法测定50μL总蛋白质。向剩余的250μL中加入一体积的10％TCA，并在4℃下以13,000g离心15分钟。将所得沉淀物溶于100μL0.2mol/ L NaOH中，然后用1mol / L HCl中和。将溶液与胶原酶缓冲液（Tris-HCl，pH 7.6 20mM，CaCl 2 250mM终浓度）和10单位胶原酶在37℃温育过夜。然后，加入150μL10％TCA并在4℃下以13000g离心15分钟。将得到的上清液加入到4mL闪烁液中，并在液体闪烁计数器LS 600 TA中测量放射性。

[动物实验]

用强力霉素治疗两组6个月大的雌性杂合（HT）Col3a1敲除小鼠3个月。用含有200或800mg / kg多西环素的食物提供治疗。因为这些小鼠的初步测量食物摄入量平均为3.5克/天，动物的平均体重为25克，低剂量和高剂量组的平均药物剂量为25（Doxy25）或100（Doxy100）mg /每天kg，分别。未处理的（野生型）WT和HT小鼠维持常规饮食（NIH-07小鼠/大鼠饮食）并用作对照。 3个月后，在一般吸入麻醉（氧气中异氟醚2％）和无菌条件下，腹主动脉通过以下手术进行手术暴露和应激：通过用无菌方法将腹主动脉阻塞在脊柱上来阻止血流。在肾动脉水平压迫棉签。在髂骨分叉处按压第二个涂药器后，第一个涂药器突然松开，然后释放第二个涂药器。缝合腹部切口，将小鼠放回家笼中。干预后继续治疗。干预一周后，通过过量的异氟烷使小鼠安乐死。收集血液，收获主动脉和结肠和皮肤的部分。
