Description
技术领域
本发明属于微生物技术领域,具体涉及治疗糖尿病及相关病症的两歧双歧杆菌(
Bifidobacterium bifidum)。
背景技术
随着社会的发展,人们生活水平的不断提高和饮食结构的调整,饮食呈富余化趋势,且多大鱼大肉,高脂饮食已成为一种重要的日常膳食方式,然而由此导致代谢类疾病的发病率不断提高,其中以肥胖、糖尿病等代谢综合症最为常见,严重影响人们的身心健康。
在肠道中约有1.5 kg的细菌,数量浩瀚的肠道菌群通过与宿主长期的共同进化,已经形成了密不可分的结构、功能联系,它通过消化营养成分、提供宿主维生素及能量、参与正常免疫构建等一系列功能参与宿主稳态平衡。肠道菌群的失调已经被认为与超过50种疾病有关。近年来研究发现代谢性疾病,尤其是肥胖和糖尿病与肠道菌群密切相关,肠道菌群可以调节宿主的脂肪积累和胰岛素敏感性。临床FMT的研究表明,肥胖患者接受来自正常个体的肠道FMT6周后,胰岛素抵抗得到了显著改善。另一项研究在对171名中国成人2型糖尿病患者和174名健康志愿者的肠道菌群研究中,共识别出52484个与2型糖尿病相关的肠道细菌基因。因此益生菌在治疗肥胖、糖尿病中具有巨大的潜力。
GPR120是长链不饱和游离脂肪酸受体,具有调节胃肠道激素分泌、调节脂肪细胞发育和分化等多种生理功能。动物实验显示,高脂饮食诱导GPR120缺失小鼠会产生更为严重的肥胖、胰岛素抵抗和肝脏脂肪变性。一系列临床前研究显示GPR120激动剂能够调节葡萄糖和能量稳态,包括改善肥胖引起的慢性炎症及胰岛素抵抗、调节脂肪细胞生热和调节食欲等。人的队列研究也显示,GPR120L氨基酸序列中R270H突变与肥胖显著相关。因此,GPR120是治疗肥胖、糖尿病等代谢综合症的潜在重要靶点。
脂肪组织中有两种甘油三酯脂肪酶,脂肪组织甘油三酯脂肪酶(adiposetriglyceride lipase,ATGL)和激素敏感脂肪酶(hormone-sensitive lipase,HSL)。前者不需要激素激活即有活性,所以在基础脂解中非常重要,也是最主要的脂解酶。后者则需由脂解激素激活才有活性。二者水解的甘油三酯(TG)约占水解总量的95%。
HSL是1962年发现的,因其脂肪酶活性受激素影响很大而得名。研究表明,HSL激活剂可以通过PKA将HSL磷酸化,使其易位到脂滴中,从而促进脂解过程。胰岛素是其最重要的抑制剂。
ATGL是2004年发现的。其C端含有疏水性脂滴结合区,所以主要定位于脂滴表面。ATGL能特异性地水解TG的第一酯键,被认为是TG水解过程的限速酶,其表达减少会导致脂肪细胞和其他组织的TG大量积累,造成肥胖和其他代谢并发症。

(6)室温孵育20分钟后,使用 Spectramax i3进行荧光定量。
实验结果如图8所示,与培养基相比,ibiome001对GPR120的激活作用最强,是培养基对照的4倍,其他的两歧双歧杆菌菌株激活作用均小于2倍,证明ibiome001对GPR120的激活作用明显优于其他两歧双歧杆菌菌株。
实施例3 菌株对小鼠体重、脂肪组织重量、脂解基因表达、口服葡萄糖耐量、禁食血糖、糖化血红蛋白、血浆胰岛素的影响
选取C57BL/6J(10周,雄性)小鼠,SPF级,购自江苏集萃药康生物科技股份有限公司。小鼠适应一周后,给予小鼠60%高脂饲料(购自美迪森,货号MD12033),并同时给药,实验共分为4组:
(1)control组:对照组,灌胃0.2mL PBS溶液;
(2)Bb组:灌胃109 CFU两歧双歧杆菌ibiome001;
(3)Bb+BI组:灌胃两歧双歧杆菌ibiome001+长双歧杆菌(菌株按照1:1混合,菌落数共109 CFU);
(4)5mix(Ba+Bf+BI+Bb+Bp)组:五种双歧杆菌混合,分别为两歧双歧杆菌ibiome001(Bb),长双歧杆菌(BI),青春双歧杆菌(Ba),粪双歧杆菌(Bf)和假链双歧杆菌(Bp)(菌株按照1:1:1:1:1混合,菌落数共109 CFU)。
对小鼠体重的影响
实验开始前将上述小鼠按体重分组,实验开始后每周记录小鼠体重,共记录13周。小鼠的体重变化率和体重绝对值如图9所示。
从图9a中可看出,灌胃两歧双歧杆菌ibiome001(Bb)从第四周开始就可以显著抑制小鼠体重增长,并且这种效果一直持续到实验结束;而与其他双歧杆菌组合后,抑制体重增长的效果不显著。从图9b可以看到在灌胃两歧双歧杆菌ibiome001 13周后,小鼠的绝对体重与对照组(control)相比降低了5.53g。
对小鼠禁食血糖值和口服葡萄糖耐量的影响
实验第10周时检测小鼠的禁食血糖值并进行口服葡萄糖耐量试验(OGTT)。
OGTT实验方法:动物禁食12小时,小鼠尾尖取血用血糖试纸检测小鼠空腹血糖值(0时)同时按照2g/kg的剂量给小鼠灌胃葡萄糖溶液,然后分别在灌胃葡萄糖后的30、60、120min尾尖取血测量血糖值,绘制血糖随时间变化曲线,计算曲线下面积。
禁食血糖值结果如图10所示:灌胃两歧双歧杆菌ibiome001(Bb)可以显著降低高脂饲料诱导的肥胖、糖尿病小鼠的禁食血糖值,而与其他双歧杆菌组合后没有改善作用。
口服葡萄糖耐量(OGTT)的结果如图11a所示:与对照组(control)相比,灌胃两歧双歧杆菌ibiome001(Bb)大幅降低了糖负荷后30 min的血糖水平(
P=0.051),并且显著降低了口服葡萄糖耐量曲线下面积(图11b)。而与其他双歧杆菌组合后没有显著改善作用。
对小鼠脂肪组织重量的影响
给药13周后小鼠禁食12小时,牺牲小鼠,取血浆、脂肪组织(肠系膜白色脂肪,皮下白色脂肪,附睾白色脂肪和棕色脂肪),将脂肪组织分别称重,结果如图12所示:灌胃两歧双歧杆菌ibiome001(Bb)能够显著降低小鼠皮下白色脂肪和肠系膜白色脂肪的重量。灌胃两歧双歧杆菌和长双歧杆菌的组合(Bb+BI)仅能够显著降低小鼠的皮下白色脂肪重量。灌胃5种双歧杆菌混合物对小鼠各部位脂肪均没有影响。
对小鼠脂解基因表达的影响
取上述白色脂肪组织提取RNA,用qPCR方法检测脂解相关基因的表达量。具体方法如下:
组织RNA的提取:采用动物组织的总RNA提取试剂盒(购自天根生化科技(北京)有限公司,货号DP424)对组织中的RNA进行提取,具体操作参考试剂盒说明书,接着,利用NanoDrop及琼脂糖凝胶电泳测定RNA浓度和纯度。
逆转录:将2
μg组织中总RNA加入2
μL 5×g DNA Buffer,以RNase-Free ddH2O补足至10
μL简短离心,置于42 ℃,孵育3 min后,冰上放置10 min,再加入2
μL 10×Fast RTBuffer 2
μL,RT Enzyme Mix 1
μL,FQ-RT Primer Mix 2
μL,以RNase-Free ddH2O补足至20
μL,于42 ºC水浴15分钟后,于95 ºC反应3分钟,将产物保存于-80 ºC。
qPCR:2
μg cDNA、10
μL SYBR染液、0.8
μL引物,剩余体积用ddH2O补足(总反应体系:20
μL)。反应条件:95 ºC变性10分钟,扩增(95 ℃ 15秒,60 ºC 1分钟,共40循环)。各基因分别设2个副孔,数据处理采用2-ΔΔCT进行相对定量分析。
qPCR的结果如图13所示,结果表明:灌胃两歧双歧杆菌ibiome001(Bb)能够提高脂解基因ATGL和HSL的表达,其中ATGL的升高程度达到了显著性差异(
P<0.05)。
对小鼠糖化血红蛋白和血浆胰岛素的影响
取上述血浆,用试剂盒(购自华美生物,货号CSB-E08141m和CSB-E05071m)检测血浆中糖化血红蛋白、胰岛素含量。
糖化血红蛋白水平是衡量血糖控制的金标准,如图14所示,灌胃两歧双歧杆菌ibiome001(Bb)显著降低高脂饲料诱导的肥胖、糖尿病小鼠血浆中糖化血红蛋白的含量,而与其他双歧杆菌组合后对血浆中糖化血红蛋白的含量没有影响。
如图15所示,灌胃两歧双歧杆菌ibiome001(Bb)显著降低高脂饲料诱导的肥胖、糖尿病小鼠血浆中胰岛素的含量,而灌胃两歧双歧杆菌和长双歧杆菌的组合(Bb+BI)对血浆胰岛素含量没有影响。
综上所述,灌胃两歧双歧杆菌ibiome001(Bb)能够显著降低高脂饲料诱导的肥胖、糖尿病小鼠的体重、白色脂肪重量,提高脂解基因ATGL和HSL的表达;并且显著降低小鼠禁食血糖、口服葡萄糖耐量曲线下面积、血浆糖化血红蛋白和胰岛素含量。两歧双歧杆菌ibiome001是潜在的治疗肥胖、糖尿病等代谢综合症的功能菌株,效果优于与其他两歧双歧杆菌的组合。
