Abstract:
AIM:To analyze the expression profile of long non-coding RNA (lncRNA) in the liver tissues of drug-induced liver injury ( DILI) and immune liver injury ( ILI) .METHODS:The technique of lncRNA microarray was used to inspect the lncRNA expression profile in the mouse liver tissues that the liver injury was induced by acetaminophen or concanavalin A .The raw data of lncRNA were pretreated for normalization .RESULTS:Compared with normal hepatic tissue, the lncRNA which had more than 1.5-fold variation and significant difference (P<0.05) by statistical analysis were regarded as lncRNA with differential expression .A total of 68 lncRNA with differential expression were found in the hepatic tissues of DILI, with 21 increased more than 1.5 folds and 47 reduced more than 1.5 folds.A total of 60 lncRNA with differential expression in the liver tissues of ILI were observed , with 17 increased more than 1.5 folds and 43 reduced more than 1.5 folds.In all lncRNA, 8 was simultaneously up-regulated in 2 liver injury models , accounting for 38%and 47%respectively, while 28 was simultaneously down-regulated in 2 liver injury models, accounting for 59%and 65%re-spectively .CONCLUSION:lncRNA expression profiles of DILI and ILI change significantly in comparison with normal hepatic tissue , and there are also differences between 2 hepatic damage models .The simultaneous changes of lncRNA may participate in the same or similar pathophysiological process , while the differences may be involved in relatively particular mechanisms .
