Description
技术领域
本发明涉及鸡抗病遗传育种和营养调节技术领域,具体涉及与鸡脂肪代谢相关的lncRNA、其调控靶点及其应用。
背景技术
肝脏是维持机体脂类代谢稳态的重要器官。正常情况下,肝脏合成的甘油三酯以极低密度脂蛋白的形式进入血液,运送到各组织被摄取利用。当肝脏脂类合成代谢增强或分解代谢障碍时会引起鸡脂肪肝的发生,导致肝内脂类向肝外组织运输过程异常,最终对鸡体脂分布造成影响。已有证据表明,鸡脂肪肝的发生伴随血脂水平、腹脂以及胸、腿肌肌内脂肪含量的增加,体内多部位脂肪沉积均有不同程度的增加。
鸡脂肪肝综合征(Fatty liver syndrome,FLS)是指各种原因引起肝细胞内脂肪代谢紊乱,以肝脏肿大、发生脂肪变性为特征的一种营养代谢疾病。鸡脂肪肝的发生直接导致腹脂的过量沉积,造成生产效率的降低。鸡脂肪肝综合征不同于脂肪肝出血综合征(FLHS),FLHS除具有肝脏脂肪过度沉积和肝细胞变性特征外,还会伴随血管壁变脆而发生肝脏出血,进而致死。FLS一般不具有致死率,初期无明显临床病状,不易被发现,剖检会发现肝脏肿大、呈暗黄色、油腻、质地柔软易碎,母鸡产蛋率一般只能上升到85%左右,而后下降,很难出现产蛋高峰,给养殖企业带来巨大经济损失。此外,动物脂肪肝综合征模型也是研究脂肪代谢异常的理想素材。开发脂类代谢相关的分子标记,对于优化家禽体脂分布结构、调控脂肪的合理沉积以及家禽脂肪肝的检测和防治具有重要意义。
肝脏脂肪的合成、分解代谢,脂肪酸的摄取以及分泌过程的异常均可能导致脂肪肝的发生,而这些代谢过程受到多个关键基因和表观遗传的调控。长链非编码RNA(lncRNA)是指长度大于200个核苷酸的非编码RNA,具有组织特异性,在表观遗传调控、转录及转录后水平的基因表达调控、细胞周期及分化调控等生命活动中发挥重要作用。lncRNA主要通过lncRNA-mRNA或lncRNA-miRNA-mRNA网络调节相关基因表达,广泛参与体内甘油三酯代谢、脂肪酸氧化等过程,是人类和动物脂类代谢过程的关键调节因子。已有研究报道,lncRNA可通过调控靶基因的表达减缓肝脏脂肪变性,抑制脂肪肝的发生。
单纯通过生物信息预测筛选核心lncRNA,其准确性无疑会大打折扣。针对特定时期、特定组织进行lncRNA与mRNA深度测序,根据lncRNA的反式调控原理,构建共表达网络和功能注释,可极大地减小核心lncRNA的筛选范围。
综上所述,利用分子标记辅助选择法对脂肪肝等脂代谢异常疾病进行分析,并筛选相关调控因子及其关键靶向基因,为辅助抗病系的选育或利用营养手段进行精准饲喂,提高生产效率提供了有效的方法。

具体实施方式
下面将结合实施例对本发明的优选实施方式进行详细说明。需要理解的是以下实施例的给出仅是为了起到说明的目的,并不是用于对本发明的范围进行限制。本领域的技术人员在不背离本发明的宗旨和精神的情况下,可以对本发明进行各种修改和替换。
下述实施例中所使用的实验方法如无特殊说明,均为常规方法。
下述实施例中所用的材料、试剂等,如无特殊说明,均可从商业途径得到。
实施例1基于高通量测序技术的lncRNA和mRNA联合分析获得脂肪肝发生相关的lncRNA及其调控靶点
本实施例利用基于高通量测序技术的lncRNA和mRNA联合分析方法筛选与脂肪肝发生相关的靶标,具体方法如下:
1、实验动物和样本准备
采用矮脚京星黄鸡品系作为试验动物,采用高脂肪日粮诱导的方法诱导F0代公鸡发生脂肪肝。之后利用脂肪肝公鸡与健康母鸡交配产生后代脂肪肝组,健康公鸡与健康母鸡交配产生后代对照组。其中采用先繁育后屠宰的方式,根据屠宰后鸡脂肪肝发生情况选择性地保留相应组别的后代。利用此繁育方法可使得脂肪肝组群体中40%左右个体发生脂肪肝,而对照组不发生或很小概率的发生脂肪肝。在F3代中,将42周龄脂肪肝组中患脂肪肝个体和对照组中正常个体进行屠宰、收集肝脏样本,检测肝脏脂肪沉积情况,并将剩余样品于-80℃保存。根据肝脏HE切片与油红O切片的结果,区分出脂肪肝组和对照组的样本用于后续研究。其中,将脂肪变性面积大于1/3且具有明显脂肪沉积的表型的个体判断为脂肪肝个体;无明显脂肪变性、肝细胞形态正常、排列整齐,并且油红O切片显示无明显脂肪沉积的个体判断为正常个体。
在脂肪肝组中挑选4份脂肪肝个体样本,在对照组中挑选4份正常个体样本,使用商品化试剂盒提取肝脏组织的总RNA,并对RNA总量及纯度进行检测,分别构建用于lncRNA和mRNA测序的cDNA文库。将cDNA文库送测序公司利用HiSeq X Ten平台进行测序。
2、基于高通量测序结果分析差异表达lncRNA和mRNA
利用DESeq2软件分析脂肪肝组与对照组样本的差异表达lncRNA和mRNA。将在脂肪肝组与对照组样本中差异表达倍数绝对值大于1.5、矫正后p-value<0.05的lncRNA定义为差异表达lncRNA;将在脂肪肝组与对照组样本中差异表达倍数绝对值大于1.5、p-value<0.05的mRNA定义为差异表达mRNA。
3、差异表达lncRNA和mRNA联合分析筛选脂肪肝相关的关键lncRNA
(1)对所有差异表达lncRNA与差异表达mRNA进行联合分析,即进行Pearson相关性分析,构建共表达网络。将相关系数绝对值大于0.95、p-value<0.05定义为显著相关;
(2)对共表达网络进行分析,将每对lncRNA-mRNA定义为一个度(degree),表示在共表达网络中的地位。发现LNC_006756具有最高的度(45),表明其处于网络最核心地位(表1)。最后对LNC_006756的靶基因进行功能注释,LNC_006756的靶基因包括FABP1、HSD17B122、HAO1等,其中,FABP1与HSD17B122基因为已知参与脂肪代谢的相关基因;同时根据相关数据库的注释结果,HAO1基因可能参与肝脏的氧化还原过程和脂肪酸α氧化过程。
上述靶基因预测结果表明,LNC_006756为脂肪肝与健康肝脏中最核心的差异lncRNA,而FABP1、HSD17B122和HAO1为LNC_006756潜在调控的靶基因,且与脂类代谢过程可能相关,因此推测LNC_006756能够通过调节FABP1、HSD17B122或HAO1的表达,参与脂肪肝的发生过程。
表1LNC_006756的调控靶基因及其富集分析结果
实施例2利用不同群体对LNC_006756及其预测靶基因与脂肪肝的相关性进行验证
利用实时荧光定量PCR(qRT-PCR)对实施例1中鉴定获得的与鸡脂肪肝相关的关键lncRNA LNC_006756及其调控靶基因FABP1、HSD17B122和HAO1的表达水平进行扩大样本验证。
1、实验样本准备
以42周龄矮脚京星黄鸡脂肪肝组与对照组群体(F3代)作为试验动物。每组样本数>10。取样过程同实施例1,记录体重、肝脏指数等表型指标,采集肝脏组织,放于-80℃保存。
2、LNC_006756和HAO1的差异表达验证
采用TRIzol法提取肝脏组织的总RNA,LNC_006756、FABP1、HSD17B122和HAO1的qRT-PCR检测方法如下:

qRT-PCR检测每次设置3个平行管反应,以β-actin与RPS6作为内参。qRT-PCR反应程序为:95℃30s;95℃3s,60℃34s,40个循环。
3、实验结果分析
肝脏指数检测:根据每个个体的肝重与活体重计算肝脏指数,计算公式为:肝脏指数=肝脏重量/活体重×100%。
LNC_006756与HAO1及表型指标的关联分析:根据线性回归计算原理,将肝脏LNC_006756的表达量分别与HAO1的表达量及肝脏指数进行相关分析,p<0.05定义为显著相关。
统计学分析:采用SPSS 25.0软件(SPSS,Chicago,IL,USA)进行分析。均数间比较采用t检验或曼惠特尼检验,p<0.05定义为有差异显著性,具有统计学意义。分析各表型组间表达差异。
qRT-PCR结果表明,脂肪肝组LNC_006756的表达量是对照组的27.9倍,表达水平差异极显著(图1);脂肪肝组HAO1的表达量是对照组的1.9倍,表达水平差异极显著(图2)。肝脏指数检测结果表明,脂肪肝组个体的肝脏指数是对照组的1.4倍,差异显著(图3)。相关分析结果表明,LNC_006756与HAO1表达量显著相关(r=0.45,p<0.05)(图4);LNC_006756与肝脏指数极显著相关(r=0.76,p<0.0001)(图5);HAO1与肝脏指数显著相关(r=0.49,p<0.05)(图6)。
而另外两个预测靶基因FABP1和HSD17B12基因,虽然在脂肪肝组和对照组间呈现差异表达,但是与LNC_006756表达的相关性不显著。因此还不能确定其为LNC_006756作用的靶基因。
实施例3在后代群体中验证LNC_006756及其预测靶基因与脂肪肝的相关性
在后代群体中利用实时荧光定量PCR(qRT-PCR)对实施例1中鉴定获得的LNC_006756及其调控靶基因HAO1与鸡脂肪肝的相关性进行验证。
1、实验样本准备
以45周龄矮脚京星黄鸡脂肪肝组与对照组群体(F4代)作为试验动物。每组样本数>10。取样过程同实施例1,采集肝脏组织,放于-80℃保存。
2、LNC_006756和HAO1的差异表达验证
验证方法同实施例2,具体如下:
采用TRIzol法提取肝脏组织的总RNA,LNC_006756和HAO1的qRT-PCR检测方法如下:
(1)LNC_006756的qRT-PCR检测:利用FastKing cDNA第一链合成试剂盒(TIANGEN,中国)进行反转录;以反转录得到的cDNA为模板,利用试剂盒KAPA SYBR FAST UniversalqPCR Kit(KAPA,美国)进行qRT-PCR。
qRT-PCR使用的上、下游引物序列如下:
SEQ ID NO.3:F:5’-CTGGGGGCATGCAATGATTC-3’;
SEQ ID NO.4:R:5’-GCGTGAAGGATGGAAAACAAC-3’。
qRT-PCR检测每次设置3个平行管反应,以β-actin与RPS6作为内参。qRT-PCR反应程序为:95℃30s;95℃3s,60℃34s,40个循环。
(2)HAO1的qRT-PCR检测:利用FastKing cDNA第一链合成试剂盒进行反转录;以反转录得到的cDNA为模板,利用试剂盒KAPA SYBR FAST Universal qPCR Kit进行qRT-PCR。
qRT-PCR使用的上、下游引物序列如下:
SEQ ID NO.5:F:5'-CGGTTTGTGTTGCTGATTT-3';
SEQ ID NO.6:R:5'-TGCTGCTACATTATCTGCTA-3'。
qRT-PCR检测每次设置3个平行管反应,以β-actin与RPS6作为内参。qRT-PCR反应程序为:95℃30s;95℃3s,60℃34s,40个循环。
3、实验结果分析
结果分析方法同实施例2,具体如下:
LNC_006756与HAO1及表型指标的关联分析:根据线性回归计算原理,将肝脏LNC_006756的表达量分别与HAO1的表达量及肝脏指数进行相关分析,p<0.05定义为显著相关。
统计学分析:采用SPSS 25.0软件(SPSS,Chicago,IL,USA)进行分析。均数间比较采用t检验或曼惠特尼检验,p<0.05定义为有差异显著性,具有统计学意义。分析各表型组间表达差异。
qRT-PCR结果表明,在F4代中,脂肪肝组LNC_006756的表达量是对照组的5倍,表达水平差异显著(图7);脂肪肝组HAO1的表达量是对照组的1.6倍,表达水平差异显著(图8)。肝脏指数检测结果表明F4代脂肪肝组个体的肝脏指数是对照组的1.4倍,差异显著(图9)。相关分析结果表明,F4代中LNC_006756与HAO1表达量极显著相关(r=0.72,p<0.0001)(图10);LNC_006756的表达量与肝脏指数极显著相关(r=0.61,p<0.01)(图11)。
实施例4一种鸡脂肪肝检测试剂盒及其检测方法(1)
本实施例提供一种鸡脂肪肝检测试剂盒,其包括如表2所示的组分。
表2鸡脂肪肝检测试剂盒的组分
本实施例还提供一种鸡脂肪肝的检测方法,具体如下:
(1)提取待测鸡肝脏样本的总RNA;
(2)以oligo-dT为3’引物,利用反转录酶进行lncRNA的反转录;
(3)采用如SEQ ID NO.3-4所示的引物进行LNC_006756的qRT-PCR检测;
(4)以正常鸡肝脏样本作为对照,根据LNC_006756的表达水平,判断待测鸡是否患有脂肪肝;判断依据为:若待测鸡的LNC_006756表达水平显著高于正常鸡,则判断待测鸡患有脂肪肝。
实施例5一种鸡脂肪肝检测试剂盒及其检测方法(2)
本实施例提供一种鸡脂肪肝检测试剂盒,其包括如表3所示的组分。
表3鸡脂肪肝检测试剂盒的组分
