Abstract: In previous work,a novel lncRNA (PAANCR) was found to significantly associated with porcine lipogenesis,so the aim of this study was to investigate the expression of PAANCR in porcine different tissues and fatten periods and its relationship with lipogenesis.10 healthy Landrace×Large White piglets were selected,3 pigs were randomly selected and slaughtered at 90 and 210 days,respectively.Real-time PCR was used to detected the expression files of PAANCR,meanwhile Oil Red O staining and Real-time PCR were used to analyze lncRNAB130024G19Rik's (a mouse lncRNA,the homologue of PAANCR) effect on lipid deposition in 3T3-L1 preadipocyte.The results showed that the expression trends of PAANCR was tissue- and development-specific,its expressional level was higher in lung,uterus,spleen,kidney and adipose tissues,its expression levels was up-regulated in liver,small intestine and brain during the development,which couldn't be detected in muscle.During differentiation,when the expression of lncRNAB130024G19Rik was knockdown,the expression level of genes associated with adipogenesis and lipid deposition were down-regulated.The results indicated that PAANCR could be used as candidate factor for porcine lipogenesis,and it was meaningful for understanding the molecular mechanism of lncRNA on lipogenesis.
