| 摘要: |
| [目的]筛选出多氯联苯(PCBs)胁迫下红树蚬(Polymesoda erosa)的实时荧光定量PCR (qRT-PCR)最适内参基因,为进一步开展分子毒理学研究奠定基础。[方法]以β-actin、18S rRNA、GAPDH和α-tubulin为候选内参基因,qRT-PCR测定PCBs胁迫下4个候选内参基因在红树蚬外套膜、鳃、闭壳肌和肝胰腺组织中的表达水平,应用geNorm、NormFinder和BestKeeper软件分析其表达稳定性。[结果]geNorm软件分析表明β-actin表达最稳定;NormFinder软件分析发现,外套膜、鳃和肝胰腺组织中β-actin的稳定性最好,闭壳肌组织中β-actin(0.454)表达稳定性略微低于α-tubulin(0.425),排第2位;BestKeeper软件分析表明,外套膜和鳃组织中β-actin最稳定,肝胰腺和闭壳肌组织中GAPDH最稳定,β-actin排位第2位。[结论]筛选β-actin为红树蚬在PCBs胁迫下的qRT-PCR最适内参基因。 |

| Abstract: |
| [Objective] To select the suitable reference genes in the mangrove mud clam (Polymesoda erosa) exposed to polychlorinated biphenyls (PCBs) by using quantitative real-time PCR (qRT-PCR), which will be conducive to further research in molecular toxicology.[Methods] β-actin, 18S rRNA, GAPDH and α-tubulin were chosen as four candidate reference genes to test their expressed level in different tissues (mantle, gill, adductor muscle and hepatopancreas)of the mangrove mud clam under PCBs stress by using qRT-PCR method.The expression stability of these candidate reference genes were analyzed and evaluated with three software-based approaches (geNorm, NormFinder and BestKeeper).[Results] geNorm analysis showed that β-actin was the most stable expressed gene among the four candidate reference genes.NormFinder analysis found that β-actin was the most stable expressed gene in mantle, gill, and hepatopancreas, but in adductor muscle tissue, β-actin (0.454) was slightly less stable than α-tubulin (0.425) and ranked as the second.BestKeeper analysis showed that β-actin was the most stable expressed gene in mantle and gill tissues, whereas GAPDH was the most stable expressed gene and β-actin was ranked as the second in adductor muscle and hepatopancreas tissues.[Conclusion] β-actin can be used as a reference gene for mangrove mud clam under PCBs stress. |
