Description
技术领域
本发明涉及生物医药技术领域,具体地说,涉及海藻提取物GV971在制备治疗多囊卵巢综合征药物中的应用。
背景技术
多囊卵巢综合征(PCOS)是生育年龄妇女常见的一种复杂的内分泌及代谢异常所致的疾病,以慢性无排卵(排卵功能紊乱或丧失)和高雄激素血症(妇女体内男性激素产生过剩)为特征,主要临床表现为月经周期不规律、不孕、多毛和/或痤疮,是最常见的女性内分泌疾病。
海藻提取物GV971是酸性寡糖糖链类(AOSC)化合物。AOSC来源于翅藻科植物昆布(Echlonia Kurome Okam),可对抗Aβ诱导小鼠海马神经元凋亡。合成系列AOSC衍生物,发现GV971可直接与Aβ结合,阻止Aβ诱导的SH-SY5Y细胞凋亡。GV971口服吸收良好并可迅速通过血脑屏障;还可改善东莨菪碱及Aβ诱导的小鼠认知障碍。临床Ⅲ期实验显示GV971安全性良好,显著改善AD患者认知障碍,有望成为新型抗AD临床用药。

实验产生四组小鼠:安慰剂对照组(C),来曲唑组(L),安慰剂小鼠灌胃GV971组(G),来曲唑小鼠灌胃GV971组(LG)。
1.5小鼠动情周期检测
从造模第7天开始,每日上午9点行阴道涂片,直至造模完成。沾取:将消毒的10ul枪头吸取少量无菌生理盐水,轻轻插入小鼠的阴道内,吹吸数次。涂片:将带有阴道内含物的生理盐水置于载玻片上做成涂片,然后将涂片散在空气中自然干燥(以载玻片上发白为准)。固定:将玻片置于95%乙醇中固定30-60min。染色:吉姆萨染色法染色。结果观察:将涂片置于显微镜下,观察阴道涂片的组织学变化,确定动情周期变化的不同阶段。
动情前期(P):显微镜下可见阴道涂片中有核上皮细胞占多数,有的是单个的,有的呈片状,可伴有少量白细胞。
动情期(E):涂片中有很多无核的角化鳞状细胞,细胞大而扁平,边缘不整齐,视野中看不到或很少白细胞与上皮细胞。
动情后期(M):涂片中角化上皮细胞减少,出现许多白细胞及有核上皮细胞。
动情间期(D):小鼠阴道粘膜薄,阴道涂片中几乎全是白细胞。
1.6糖耐量试验
(1)将小鼠换入干净的笼子禁食12h(禁食期间保证正常的饮水)后,称取每只小鼠的体重,并逐一对小鼠进行标记,以便在实验过程中能快速辨认所测小鼠。

(2)确定雌鼠怀孕后,证明与其合笼的雄鼠性能力正常,可以使用,若不能使同笼雌鼠怀孕,则更换雄鼠;
(3)挑选出足够数目的生育力正常的雄鼠,与待检测雌鼠1:1合笼;
(4)待见栓后10天解剖雌鼠,计数子宫内胚胎数。
1.9血清激素、血清及卵巢组织的IL-18检测
将所得血液3000g离心10min,取上层血清分装后-80℃冻存,卵巢组织取出置于含蛋白酶抑制剂的PBS中研磨匀浆分装后-80℃冻存,根据睾酮定量测定试剂盒、LH定量测定试剂盒说明、DHEAS定量试剂盒说明和IL-18定量试剂盒说明,用酶联免疫吸附测定各激素含量。
1.10卵巢形态检测

(9)逆转录为cDNA,加入各炎症因子引物进行聚合酶-链式反应。
1.12卵巢组织转录组测序实验
(1)提取total RNA:
从组织样品中提取total RNA,利用Nanodrop2000对所提RNA的浓度和纯度进行检测,琼脂糖凝胶电泳检测RNA完整性,Agilent2100测定RIN值。单次建库要求RNA总量≥1ug,浓度≥35ng/μL,OD260/280≥1.8,OD260/230≥1.0。
(2)Oligo dT富集mRNA:
真核生物mRNA 3’末端具有ploy A尾的结构,利用带有Oligo(dT)的磁珠与ploy A进行A-T碱基配对,可以从总RNA中分离出mRNA,用于分析转录组信息。
(3)片段化mRNA:
Illumina Novaseq 6000平台是针对短序列片段进行测序,富集得到的mRNA是完整的RNA序列,平均长度达几kb,因此需要对其进行随机打断。加入fragmentation buffer,可以将mRNA随机断裂,通过磁珠筛选分离出300bp左右的小片段。
(4)反转合成cDNA:
在逆转录酶的作用下,加入六碱基随机引物(random hexamers),以mRNA为模板反转合成一链cDNA,随后进行二链合成,形成稳定的双链结构。
(5)连接adaptor:
双链的cDNA结构为粘性末端,加入End Repair Mix将其补成平末端,随后在3’端加上一“A”碱基,用于连接Y字形的接头。
(6)Illumina平台上机测序:
①文库富集,PCR扩增15个cycles;
②2%琼脂糖胶回收目的条带;
③TBS380(Picogreen)定量,按数据比例混合上机;
④cBot上进行桥式PCR扩增,生成clusters;
⑤Illumina平台测序(PE文库,读长2×150bp)。
1.13小鼠肠道微生物多样性测序及分析
(1)收集新鲜的小鼠粪便于1.5mlEP管中,液氮快速冷冻后-80℃冻存。
(2)微生物多样性测序:根据 soil DNA Kit(Omega Bio-Tek,Norcross,GA)进行微生物群落总DNA抽提,使用NanoDrop 2000NanoDrop UV-vis测DNA浓度、纯度;用1%琼脂糖凝胶电泳测DNA提取质量,用338F(5’-ACTCCTACGGGAGGCAGCAG-3’)(SEQ ID NO:1)和806R(5’-GGACTACHVGGGTWTCTAAT-3’)(SEQ ID NO:2)对16SrRN基因V3-V4区进行PCR扩增(GeneAmp 9700,ABI,Waltham,MA)。将同一样本的PCR产物混合后使用2%琼脂糖凝胶回收PCR产物,利用AxyPrep DNA Gel Extraction Kit进行回收产物纯化,2%琼脂糖凝胶电泳检测,并用QuantusTM Fluorometer(Promega,USA)对回收产物进行检测、定量。使用NEXTFLEX Rapid DNA-Seq Kit进行建库。利用Illumina公司的MiseqPE300平台进行测序。
(3)序列拼接及注释:Fastp软件对原始测序序列进行质控,Flash软件进行拼接。Usearch软件根据97%的相似度对序列进行OTU聚类并剔除嵌合体。利用RDP classifier对每条序列与Silva数据库(SSU132)进行比对,设置比对阈值为70%,得到物种分类注释结果。
(4)数据分析:Alpha多样性分析、物种组成分析、物种比较分析、物种差异分析,明确特征性上调菌属。
(5)基于OTU arcsin-square根转换计数数据,使用加权基因共表达网络分析(WGCNA)生成共现网络,输入大于15个样本的数据,包括OTU根转化技术数据、体重、血清T、LH、FSH、E2、P以及DHT值,以及是否为PCOS动物模型(以0或1表示);选择构建一个有向网络,并选择合适的power值,即要使构建的网络符合无标度网络特征;层级聚类树显示各个模块;利用定义为模块第一主成分的模块本征otu计算模块与代谢性状之间的皮尔逊相关,绘制模块之间相关性图。相关性的显著性由渐近p值决定的。使用snaR包中的gplot函数实现网络的可视化,找到与疾病相关的微生物种类biomarker。
2 实验结果
2.1 基础指标
图1至图5说明了来曲唑诱导小鼠出现了体重增加、卵巢重量增加、性腺旁脂肪垫增加、糖耐量损害以及胰岛素抵抗等代谢异常表型,在给予葡萄糖或注射胰岛素后,L组小鼠的血糖水平较对照组有明显升高,且血糖下降较慢。而通过GV971的灌胃处理后,以上代谢异常表型得到改善。(注:图1至图3,与L组比较,★P<0.05,★★P<0.01,★★★P<0.001;图4和图5,C组与L组比较,★P<0.05,★★P<0.01,★★★P<0.001,L组与LG组比较,#P<0.05)。
2.2动情周期
图6至图9体现了四组小鼠的动情周期。安慰剂组小鼠的典型动情周期(图6),来曲唑组小鼠的典型动情周期(图7),安慰剂灌胃GV971组小鼠的典型动情周期(图8),来曲唑组小鼠灌胃GV971组的典型动情周期(图9)。其中P为动情前期、E为动情期、M为动情后期、D为动情间期)。动情周期是评价小鼠性周期的一个重要指标,正常小鼠的动情为4-5天,动情前期(P)、动情期(E)、动情后期(M)及动情间期(D)重复出现,动情周期紊乱是PCOS小鼠的一个重要特征。
图7中体现出来曲唑小鼠长期处于动情间期,而经过GV971灌胃的来曲唑小鼠的动情周期表现出各个动情时期的重复出现,GV971灌胃的安慰剂组小鼠与对照组无明显差异。
2.3性激素水平
图10至图12体现了四组小鼠的血清性激素的水平。来曲唑组小鼠血清的睾酮水平明显升高(图10),脱氢睾雄酮的水平以及黄体生成素的水平也明显升高(图11,图12),而雄激素水平升高也是PCOS的一个重要病理表现和诊断标准。而经过GV971干预的来曲唑小鼠与来曲唑小鼠相比,睾酮水平明显降低,LH水平也显著降低。(注:与L组比较,★P<0.05,★★P<0.01,★★★P<0.001)
2.4生育力
图13体现了四组小鼠的生育力实验。来曲唑组小鼠的妊娠胚胎数较对照组显著减少,GV971的干预使来曲唑小鼠的妊娠胚胎数增加,生育力得到改善,说明GV971改善了来曲唑小鼠的卵巢排卵异常。(注:与L组比较,★P<0.05,★★P<0.01)
2.5卵巢形态、卵泡数及黄体数
图14至图17体现了对照组、来曲唑组小鼠及安慰剂灌胃GV971小鼠以及来曲唑灌胃GV971小鼠的卵巢形态。图14为对照组小鼠的典型卵巢HE染色,图15为来曲唑组小鼠的典型卵巢HE染色,图16为安慰剂灌胃GV971组小鼠的典型卵巢HE染色,图17为来曲唑灌胃GV971小鼠的典型卵巢HE染色,图18为四组小鼠卵巢黄体数,图19为四组小鼠囊泡状卵泡数(其中,*表示黄体,#表示囊状卵泡,与L组比较,★P<0.05,★★P<0.01)。
图14至图17中体现了来曲唑小鼠的黄体计数较对照组明显减少,而囊泡状卵泡数明显增多,说明来曲唑诱导小鼠出现了卵巢多囊样的形态变化,而经过GV971干预后,黄体数增加,囊状卵泡明显减少,说明GV971改善了PCOS模型鼠的卵巢形态异常和排卵异常。
2.6卵巢转录组测序分析
图20体现了四组小鼠的卵巢转录组测序的聚类模型的热图。可以看到LG组小鼠与L组小鼠分别都自成一个聚类,而C组和G组聚类模式相似(左侧前三列分别为样本LG1、LG3、LG6,此三列相关基因表达明显上调,呈现与另三组不同的聚类模式;可见L13、L12、L7此三组呈现相同聚类模式;C18、G22、C15、C16聚类模式更接近)。
图21体现了四组小鼠的卵巢转录组测序的聚类PCA图。可以看出LG组小鼠自成一个聚类模式。
图22和图23体现了C与L、L与LG之间的差异基因火山图。可以看出L组较C组上调表达的基因包括IL-17rb、IL-33、IL-13ra2等促炎症因子,还包括Col6a5、Col4a3、Vcam1、Fads1等与卵巢血管合成及组织增生相关的功能基因,和Hsd17b3、Cyp27a1、Cyp17a1等芳香酶类促进雄激素合成相关基因。说明来曲唑组小鼠的卵巢局部呈现免疫激活、雄激素合成激活的状态(图22)。而经过GV971的干预后的LG组Cyp17a1的表达下调,促炎症因子IL-17rb、IL-34,以及卵巢功能基因Col6a5、Vcam1、Fads1等表达也下调,说明GV971的干预改善了PCOS样小鼠卵巢局部的免疫激活状态,改善了其卵巢组织结构增生的表现(图23)。
通过图24和图25,C与L、L与LG差异基因的KEGG富集分析,体现了L组较C组的炎症及免疫相关通路激活,以及代谢通路激活(图25);而GV971的干预使L组的卵巢局部炎症相关通路的激活改善,尤其注意其中肠道免疫通路的下调(图26)。
图26和图27体现了GV971的干预使L组的卵巢局部IL-18的表达量下调(图26),以及血清IL-18的水平明显下调(图27)。(注:与L组比较,★P<0.05,★★P<0.01,★★★P<0.001)
2.7肠道菌群
图28至图31体现了四组小鼠的肠道菌群变化情况。可以看出,来曲唑组小鼠的肠道菌群α多样性较对照组明显降低,而肠道菌群α多样性的降低是在PCOS中的变化已经达成了共识,而GV971的干预使α多样性得到了恢复(图28注:与L组比较,★P<0.05)。来曲唑小鼠肠道菌群β多样性的聚类模式与LG组不同,而C组与G组的聚类模式大致相同,说明GV971的干预使PCOS样小鼠的肠道β多样性发生了改变(图29)。通过对四组小鼠的肠道菌群属水平的差异菌属的分析,可以看出来曲唑小鼠的norank_f_Muribaculaceae菌属的丰度较对照组升高,而GV971的干预使该菌属的丰度下调(图30注:组间差异★P<0.05)。并且将小鼠血清IL-18与差异性菌属进行Spearman相关性分析中,发现IL-18水平与上述的norank_f_Muribaculaceae丰度水平呈现正相关性(图31注:★P<0.05,★★P<0.01,单元格颜色越深,说明相关性越强)。
以上结果说明,GV971可以改善来曲唑小鼠的代谢及生殖异常表型,并且这种改善作用是通过调节肠道菌群的失调,进而改善了卵巢局部炎症激活状态而实现的。
以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明方法的前提下,还可以做出若干改进和补充,这些改进和补充也应视为本发明的保护范围。
