NCR1 and liver cancer: MiR-544 was significantly upregulated (Fig. 1a; P < 0.05) while NCR1 (Fig. 1a, b; P < 0.05) and RUNX3 (Fig. 1b; P < 0.05) were markedly downregulated in NK cells of liver cancer patients compared with those of healthy population, hinting that miR-544 level was negatively associated with the expression of NCR1 and RUNX3.
