Figure 8. Effect of DDX49 on migration after HCC cells treat with morphine. Phase micrographs of migration HCC cells with DDX49 knock down or over expression in wound healing assay after exposure to morphine(10μM). Scale approximately 500 μm. Morphine QGY-7703 cells were treated with morphine (10μM) for 48h. *P < 0.05 compare to the respective control group. NS non-significant different.
