ABSTRACT
Objective To explore the link between the expression of long non-coding RNA(lncRNA)metastasis associated lung adenocarcinoma transcript 1(MALAT1)and IL-6/signal trans ducers and activators of transcription 3(STAT3)signaling pathway in isoniazid induced rats liver injury. Methods Fifty-six specific pathogen-free(SPF)SD rats were randomly divided into experimen?tal group(48 rats)and control group(8 rats),each with half females and half males. The rats in experimental group were given isonia?zid of 63 mg/(kg·d)for 3,7,10,14,21 and 28 d,with 8 rats at the same time point of each day. The rats in control group were giv?en distilled water by intragastric administration. Serum levels of ALT and AST were measured by automatic biochemical analyzer;SYBR green real-time polymerase chain reaction was used to test the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA in the liver. Results Liver tissue injury occurred after 7 days and worsened with the extention of administration time. Compared with the rats in the control group,the expression level of lncRNA MALAT1 and IL-6/STAT3 mRNA as well as ALT and AST showed a trend of increase(P<0.01). The expression of ALT,AST and lncRNA MALAT1 declined at different degrees on 28(P<0.05). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels were positively correlated(P<0.01). LncRNA MALAT1 and IL-6/STAT3 mRNA expression levels had a positive correlation with the contents of ALT and AST(P<0.01). Conclusion The expression level of lncRNA MALAT1 in isoniazid induced liver injury rat models showed an abnormal rising trend,and the positive detection time preceded that of ALT and AST. The mechanism may be related to the activation of IL-6/STAT3 signaling pathway.
