摘要:

鸡绿蛋壳特征的形成与内源性逆转录病毒EAV-HP启动蛋壳腺中溶质载体有机阴离子转运蛋白家族成员1B3(SLCO1B3)的高表达相关。作为代谢核心器官,鸡的肝脏中SLCO1B3高表达,但EAV-HP的插入突变下调鸡肝脏中SLCO1B3的表达,该过程中鸡肝脏的代谢组学研究未见报道。本研究以芦花鸡为研究对象,利用绿壳蛋判型引物确定38只芦花鸡中产绿壳蛋频率为47.4%;EAV-HP+/+和EAV-HP+/-整合均显著降低芦花鸡肝脏中SLCO1B3转录水平(P<0.05),尤其是EAV-HP+/+整合影响效果更为显著;代谢组学共筛选到80个差异代谢物,其中上调30个,下调50个;代谢物所富集到的通路主要涉及牛磺酸和次牛磺酸代谢、柠檬酸循环(TCA循环)、碳水化合物代谢、醚脂质代谢及丙氨酸、天冬氨酸和谷氨酸代谢等生物过程。研究结果揭示了EAV-HP插入突变所致的SLCO1B3表达下调对芦花鸡肝脏代谢物及代谢通路的影响,为充分了解和利用内源性逆转录病毒改善鸡群生产性能提供研究思路和方向。

Abstract:

The formation of green eggshell characteristics in chickens is associated with the high expression of Solute Carrier Organic Anion Transporter Family Member 1B3 (SLCO1B3) in eggshell glands initiated by the endogenous retrovirus EAV-HP. As a core metabolic organ, SLCO1B3 is highly expressed in the chicken liver. The insertion mutation of EAV-HP downregulates the expression of SLCO1B3 in the chicken liver. Metabolomics studies of chicken liver during this process have not been reported. This study took the Luhua chicken as the research object. Using the green-shelled egg genotypic primers, it was determined that the frequency of green-shelled eggs produced in 38 Luhua chickens was 47.4%. Both the integration of EAV-HP+/+ and EAV-HP+/- significantly reduced the transcriptional level of SLCO1B3 in the liver of Luhua chicken (P<0.05), especially the effect of the integration of EAV-HP+/+ was especially significant. A total of 80 differential metabolites were screened out by metabolomics, among which 30 were up-regulated and 50 were down-regulated. The pathways through which metabolites are enriched mainly involve biological processes such as taurine and hypotaurine metabolism, the citric acid cycle (TCA cycle), carbohydrate metabolism, ether lipid metabolism and alanine, aspartic acid and glutamic acid metabolism. The research results revealed the effect of down-regulation of SLCO1B3 expression caused by EAV-HP insertion mutation on liver metabolites and metabolic pathways in chickens, providing research ideas and directions for fully understanding and utilizing endogenous retroviruses to improve the production performance of chicken flocks.
