Abstract:

The aim of this study was to obtain the CDS of CIDEB and CIDEC gene,detect the expression of CIDEB and CIDEC in different tissues of goats,predict their interaction proteins.It would provide basial data for revealing the regulatory role of CIDEs in lipid metabolism.The CDS of CIDEB and CIDEC gene were cloned by RT-PCR,and the biological characteristics and interaction proteins of CIDE proteins were analyzed by online tools.Real-time quantitative PCR(RT-qPCR)was used to detect the expression of CIDEs and the genes,encoding the interaction proteins,in different tissues of goats,following the correlation analyses by a SPSS software.The CDS of CIDEB was 660 bp,encoding 219 amino acids,while the CDS of CIDEC was 714 bp,encoding 237 amino acids.Phylogenetic tree analysis showed that goat CIDEA,CIDEB and CIDEC were closely related to corresponding genes from sheep.RT-qPCR detection showed that CIDEA,CIDEB and CIDEC were highly expressed in the rumen,liver and small intestine of goat,respectively.The expression of CIDEA was significantly correlated with the expression of DFFB (P<0.01),ELOVL3 (P<0.01),DIO2 (P<0.05),TMEM26 (P<0.05),PRDM16 (P<0.05)and PLIN1 (P<0.05)in rumen.The expression of CIDEB was significantly correlated with that of DFFA and SDR39U1 in liver(P<0.05).The expression of CIDEC was obviously correlated with that of PLIN2,GPLD1 and ADIPOQ in small intestine(P<0.05).Through the analysis,we found genes related to the expression level of CIDEs,which could provide a theoretical basis for further revealing the role of CIDE gene in lipid metabolism and its regulatory network.Moreover,the proteins of CIDEs were all lipid-droplet related proteins,and could also provide a reference for further studying the precise mechanism of lipid droplet formation.
