Abstract

MicroRNAs are a group of small non-coding RNAs with modulator activity of gene expression. Recent studies have uncovered a profound role of microRNAs in liver diseases. This study aimed to investigate a potential relationship between microRNA-223 (miR-223) expression and hepatic ischemia/reperfusion injury in mice. Quantitative RT-PCR analysis showed that miR-223 expression levels were greatly up-regulated in the livers after 75 min ischemia followed by 120 min reperfusion when compared to sham controls (2.59 ± 0.23 vs. 0.83 ± 0.15; < 0.01). Correlation analysis also revealed that hepatic miR-223 expression level was significantly positively correlated with serum markers of ischemic injury. By prediction assay of miRNA targets mRNA, acyl-CoA synthetase long-chain family member 3, ephrin A1, and ras homolog gene family member B were predicted to be downstream targets of miR-223. Thus, we conclude that hepatic ischemia/reperfusion injury might be another form of liver disease that is associated with alteration in miR-223 expression.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
