摘要:

为筛选出山羊不同组织、不同时期骨骼肌及骨骼肌卫星细胞(Skeletal muscle satellite cells,SMSCs)中稳定表达的内参基因,以出生后3日龄的山羊不同组织(心、肝、脾、肺、肾、大脑、大肠、小肠、背最长肌、臂三头肌和半膜肌)和不同时期(3、30、60、90和120 d)的3种骨骼肌(背最长肌、臂三头肌和半膜肌)以及培养至不同阶段(1、3、4和7 d) 的山羊SMSCs为研究对象,运用qRT-PCR 技术及geNorm分析软件,探索9个内参基因(ACTINGAPDHTOP2β、YWHAZ、SDHA、PGK1、RP2、RPL4和HPRT1)mRNA的表达稳定性。结果表明,在同一时期的11个组织中,内参基因表达稳定度的排序:HPRT1>RP2>TOP2β>SDHA>GAPDH>ACTIN>YWHAZ>PGK1>RPL4,需要2个内参基因 (HPRT1和RP2) 共同校正目的基因的表达;在不同发育时期的骨骼肌中,各内参的稳定度:YWHAZ>ACTIN>HPRT1>RPL4 >TOP2β>SDHA>PGK1>GAPDH>RP2,需引入3个内参(YWHAZACTINHPRT1)才能准确地校正定量结果;在SMSCs中各内参表达的稳定度排序:PGK1>SDHA>ACTIN>RPL4>GAPDH>TOP2β>YWHAZ>RP2>HPRT1,需要3个合适的内参(PGK1、SDHAACTIN)作为标准化指标校正定量数据。本试验分别筛选出了能在山羊同一时期不同组织、不同发育时期的骨骼肌及SMSCs中稳定表达的内参基因及需要引入的内参数目,有利于更加准确地校正基因mRNA水平的表达量,为更好地研究基因功能奠定了基础。

Abstract:

 To screen the reference genes of stable expression in different tissues,skeletal muscle of different development periods and skeletal muscle satellite cells (SMSCs) in goat,the expression levels of 9 reference genes of ACTINGAPDHTOP2β,YWHAZSDHAPGK1,RP2,RPL4 and HPRT1 mRNA were detected in different tissues (heart,liver,spleen,lung,kidney,brain,small intestine,large intestine,longissimus dorsitriceps brachii and semimembranosus ) of 3-day-old postnatal kids,and the longissimus dorsitriceps brachii and semimembranosus of 3,30,60,90 and 120 days old goat and the SMSCs cultured for 1,3,4 and 7 d.The data of expression levels were analyzed using the geNorm software.The results showed that the expressive stability of nine reference genes from high to low were HPRT1,RP2,TOP2β,SDHAGAPDHACTINYWHAZPGK1,RPL4,and the 2 genes (HPRT1 and RP2) were needed to normalize the qRT-PCR data in different tissues of neonatal goat kids.Meanwhile,the stability of 9 references genes decreased as following: YWHAZACTINHPRT1,RPL4,TOP2β,SDHAPGK1,GAPDHRP2,and the first 3 genes (YWHAZACTIN and HPRT1) were suggested to accurately measure the true expression levels of target genes during the skeletal muscle of different development stages.Additionally,their expressive stability rank were PGK1,SDHAACTINRPL4,GAPDHTOP2β,YWHAZRP2,HPRT1 in SMSCs,and 3 genes (PGK1,SDHA and ACTIN) were recommend as standardized factors.Here,the expressive stability of 9 reference genes and suitable genes were confirmed in different tissues,the skeletal muscle of different development periods and the SMSCs in goat.This will be beneficial to the research about the expression and function of gene at mRNA level.
