RESULTS Recognition of early-phase circulating miRNAs indicating late-phase HCC recurrence after liver organ transplantation In microRNA microarray evaluation, after normalization using the expression degree of miRNAs in healthful donors, 14 considerably upregulated miRNAs had been identified in repeated recipients at a fake discovery price (FDR) of 0% in comparison to nonrecurrent recipients (Shape ?(Figure1A).1A). There is no down-regulated miRNA identified in recurrent recipients predicated on these criteria significantly. Cluster evaluation revealed how the expression degree of these 14 miRNAs in repeated recipients had been relatively greater than nonrecurrent recipients (Shape ?(Figure1B).1B). Statistical evaluation showed how the expressions of 10 out of 14 miRNAs in repeated recipients had been significantly greater than in nonrecurrent recipients (Shape ?(Shape1C1C).
