本试验旨在探究Pax7(paired box 7)基因在猪不同组织中的表达特征及其在背最长肌中的发育性表达规律.采用实时荧光定量PCR(qRT-PCR)技术和Western blotting技术检测了Pax7基因在1日龄马身猪心脏、肝脏、脾脏、肺脏、肾脏、胃、小肠、下丘脑、小脑、背最长肌、腰大肌、股二头肌12种组织中的mRNA和蛋白质表达谱,以及马身猪和大白猪从出生1日龄到180日龄7个发育阶段(1、30、60、90、120、150、180日龄)背最长肌中的发育性表达规律.结果表明,Pax7基因mRNA在背最长肌、腰大肌、股二头肌、下丘脑和小脑组织中表达,而Pax7蛋白仅在背最长肌、腰大肌和股二头肌中表达.背最长肌中Pax7基因mRNA和蛋白质的发育性表达趋势在马身猪和大白猪中基本一致.在mRNA水平上,30日龄的表达量最高,极显著高于其他日龄(P <0.01);1日龄的表达量次之;其他日龄维持低表达的稳定状态.Pax7蛋白表达量在1日龄时最高,极显著高于其他日龄(P <0.01);30日龄次之;其他日龄维持低表达的稳定状态.从出生1日龄到180日龄,马身猪背最长肌中Pax7蛋白的表达量均显著或极显著地高于大白猪(P <0.05;P <0.01).Pax7 基因的表达与组织、日龄及品种的遗传背景有关. 相似文献

本研究旨在分析环腺苷酸应答元件结合蛋白H(cyclic AMP-responsive element-binding protein 3-like 3,CREB-H)在猪不同组织中的表达谱及其在马身猪和大白猪肝脏中的发育性表达规律。采用实时荧光定量PCR和Western blotting技术检测1日龄猪12个组织(心脏、肝脏、脾脏、肺脏、肾脏、胃、小肠、小脑、下丘脑、背最长肌、股肌和腰肌)中CREB-H基因的表达谱,以及CREB-H在1、30、60、90、120、150和180日龄马身猪和大白猪肝脏中的表达规律。结果显示,CREB-H基因mRNA在马身猪的12个组织中广泛表达,其中在肝脏和小肠中高表达;CREB-H蛋白在肝脏组织中的表达量显著高于其他组织(P0.05),在心脏、脾脏和小脑中不表达。猪肝脏CREB-H基因mRNA和蛋白的发育表达受日龄、品种、品种与日龄相互作用的影响(P0.01)。马身猪和大白猪肝脏中CREB-H基因mRNA和蛋白的表达量均在1日龄时达到最大值。在各发育阶段,马身猪CREB-H蛋白的表达量均极显著高于大白猪(P0.01),且CREB-H主要在猪肝脏中表达。CREB-H在两猪种肝脏中的表达存在时空差异,可能与猪在不同发育期的脂质代谢能力有关,本试验结果为研究猪的脂质代谢调控机制提供一定的理论依据。 相似文献

试验分别采集40日龄小体型猪（巴马猪）和大体型猪（大白猪）的心脏、肝脏、脾脏、肺脏、肾脏、头骨、骨骼肌组织,利用实时荧光定量PCR检测斯钙素-1（stanniocalcin 1,STC-1）基因mRNA在各个组织中的表达水平,并通过Western blotting检测STC-1蛋白在各个组织中的分布。实时荧光定量PCR检测结果表明,STC-1基因mRNA在巴马猪和大白猪肺脏、肾脏中相对表达水平较高,在骨骼肌中的表达水平最低;除心脏和骨骼肌外,巴马猪其余各组织中STC-1基因mRNA表达水平均显著高于大白猪（P < 0.05）。Western blotting检测结果表明,巴马猪肝脏中STC-1蛋白的表达量最高,而大白猪脾脏中STC-1蛋白表达量最高,两者差异显著（P < 0.05）;巴马猪肺脏、肝脏、骨骼肌及心脏组织中STC-1蛋白表达量均极显著高于大白猪（P < 0.01）;而巴马猪肾脏、脾脏中STC-1蛋白表达量极显著低于大白猪（P < 0.01）。本研究首次对大、小体型猪不同组织的STC-1基因mRNA表达水平及其STC-1蛋白分布进行检测,导致该基因表达与分布差异的原因可能与两种猪受外界环境应激及生长发育差异有关。 相似文献

试验旨在探究载脂蛋白CⅡ(apolipoprotein Ⅱ,ApoCⅡ)基因mRNA在马身猪和大白猪肝脏组织中的发育性表达规律,揭示ApoCⅡ基因表达水平与猪脂质代谢之间的关系。采用实时荧光定量PCR技术检测了马身猪和大白猪1~180日龄(1、30、60、90、120、150和180日龄)肝脏组织中ApoCⅡ基因mRNA表达。结果表明,马身猪和大白猪肝脏组织ApoCⅡ基因mRNA发育性变化趋势存在差异,马身猪ApoCⅡ表达量从1日龄到60日龄逐渐降低,在90日龄时上升,之后逐渐降低;而大白猪从1日龄到150日龄呈现逐渐降低趋势,180日龄时回升。1日龄时,马身猪和大白猪肝脏中ApoCⅡ基因mRNA的表达量差异不显著(P>0.05),在其他阶段,两品种间的表达量存在显著或极显著差异(P<0.05或 P<0.01)。这表明肝脏中ApoCⅡ mRNA的表达具有显著的日龄依赖性和明显的品种差异性,其表达可能对猪脂质代谢有显著影响。 相似文献

为探讨杀菌/通透性增强蛋白(BPI)基因在梅山猪从初生到成年各个时期不同组织中的表达规律,利用qPCR检测初生、断奶、性成熟、体成熟4个重要发育时期(即1、35、134、158日龄)梅山猪的心脏、肝脏、脾脏、肺脏、肾脏、胃、肌肉、胸腺、淋巴结、十二指肠、空肠和回肠12个组织中BPI基因的表达水平。结果表明:4个不同发育阶段BPI基因的组织表达谱在心脏、肝脏、脾脏、肌肉和胸腺中均表现出相对一致的规律,即BPI基因的表达量一直处于极低水平,而在肠道组织中从初生到成年各时期均高度表达;BPI基因在胃中的表达程度随着日龄增长而显著提高;在小肠组织中,35日龄断奶仔猪BPI基因的表达水平极显著高于其他3个日龄。综上,推断肠道中BPI基因的高度表达是仔猪从初生就具有的抵抗大肠杆菌等病原感染属固有免疫的一部分,而在胃中的表达很可能是其后天为了抵御不断侵染的大肠杆菌等病原的结果。 相似文献

This study was aimed to investigate the expression characteristics of myoneurin (MYNN) gene in different tissues and its developmental expression in muscles (longissimus dorsi, biceps femoris and psoas major), cerebellum, liver, pancreas, kidney, stomach, spleen and lung tissues of pigs. The expression characteristics of MYNN mRNA in 11 different tissues including heart, liver, spleen, lung, kidney, cerebellum, small intestine, pancreas, stomach, biceps femoris and fat of Large White pigs and Mashen pigs at the age of 90 days and the developmental expression patterns in muscle, cerebellum, liver, pancreas, kidney, stomach, spleen at three strages (1, 90, 180 days) of Large White pigs and Mashen pigs were studied by Real-time PCR. The results showed that MYNN was widely expressed in various tissues of pigs, and there was significant difference among the tissues(P < 0.05; P < 0.01); The expression of MYNN in muscle, liver, pancreas, cerebellum, kidney, stomach, spleen, lung tissues were significant difference at three development stages of Large White pigs and Mashen pigs(P < 0.05; P < 0.01), and also had a specific rule, which indicated that it may play an important role in these pig tissues. The expression of MYNN gene could related to the tissue, age and the genetic background of breeds. The results of this study provided a better understanding of the biological functions of pig MYNN. Further studies are required to determine its molecular mechanisms, especially in the regulation of skeletal muscle development. 相似文献

The Real-time PCR results showed that the expression level of STC-1 gene mRNA was higher in lung and kidney, but was the lowest in skeletal muscle of Bama Mini pig and Large White pig. Except for heart and skeletal muscle tissues, the expression level of STC-1 gene mRNA in other tissues of Bama Mini pig was significantly higher than Large White pig (P < 0.05).The Western blotting results showed that the STC-1 protein distribution were the highest in liver and spleen of Bama Mini pig and Large White pig, respectively, and the difference was significant (P < 0.05). The STC-1 protein expression in lung, liver, skeletal muscle and heart of Bama Mini pig were extremely significantly higher than Large White pig (P < 0.01),and the STC-1 protein expression in kidney and spleen of Bama Mini pig were extremely significantly lower than Large White pig (P < 0.01). STC-1 gene mRNA and protein were firstly detected in different tissues from big and small body shape pigs,this might have a relationship with various external environments stress and development. 相似文献

The aim of this study was to investigate the developmental patterns of ApoCⅡ gene mRNA in liver in Mashen and Large White pigs, and study the relationship between the expression level of ApoCⅡ and the lipid metabolism in pigs.The mRNA relative expressions of ApoCⅡ gene in liver at seven stages of 1,30,60,90,120,150,and 180-day old in Mashen and Large White pigs were determined by quantitative Real-time PCR.The results showed that the developmental trend of ApoCⅡ mRNA expression in liver between Mashen and Large White pigs was different.The ApoCⅡ mRNA abundance was decreased from birth to 60-day old,then increased at 90-day old,and decreased again after that in Mashen pig.However,the relative expression amount in Large White pig was gradually decreased from birth to 150-day old and increased again at 180-day old.Except for the ApoCⅡ mRNA expression amount at 1-day old,the differences of the expression amount at other stages in Mashen and Large White pigs were significant or extremely significant (P<0.05 or P<0.01).The ApoCⅡ mRNA expression in liver was affected by age and breed,and could play an important role in lipid metabolism in pigs. 相似文献
