Intriguingly, the culture supernatant derived from UQCRC1-overexpressing PC cells consistently displayed a reduced chemotactic effect on NK-92MI as well as primary NK cells (p < 0.01, Figures 2D, E), which implies that UQCRC1-elicited reduction of NK cell infiltration might be attributed to soluble products from cancer cells. This evidence concerns the gene UQCRC1 and cancer.
