Abstract:

To investigate the function of tachykinin 3 receptor gene(TACR3)and the expression and distribution of its encoded product neurokinin B receptor(NK3R)in the oviduct and uterus of Ganjia Tibetan sheep,hypothalamus,oviduct and uterus tissues during estrous cycle and anestrus of Ganjia Tibetan sheep were taken as samples.The TACR3 gene coding sequence(CDS)was cloned by nested PCR.The biological function of TACR3 interacting proteins was predicted using STRING protein interaction database,Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG).Real-time Quantitative PCR(qRT-PCR),Western Blot and immunohistochemistry(IHC)were used to analyze the distribution and expression of TACR3 gene and NK3R in the oviduct and uterus during estrous cycle and anestrus of Ganjia Tibetan sheep.The results showed that the total length of the open reading frame of TACR3 gene in Ganjia Tibetan sheep was 1 395 bp,encoding 464 amino acids,and no signal peptide structure was found,with seven transmembrane structures.TACR3 may participate in biological processes such as neuropeptide signaling pathway,GnRH signaling pathway and calcium signaling pathway.The NK3R protein encoded by TACR3 was mainly expressed in the mucosal epithelium,ciliary cells,secretory cells of oviduct,uterine glands and stromal cells of uterus.In oviduct,the expression level of TACR3 mRNA was the highest in the metestrus,and the expression level of NK3R protein was the highest in the estrus.The expression levels of TACR3 mRNA and protein in uterus were the highest in the metestrus.The results showed that TACR3 was conserved in animal evolution,and TACR3 mRNA and protein were expressed in oviduct and uterus tissues at different estrus periods,which may play an important role in the reproductive process of Ganjia Tibetan sheep.
