RGS3 and hepatocellular carcinoma: As the in vitro experiment demonstrated, the UBE2MP1 transcript potently facilitates HCC cell proliferation and apoptosis resistance, and the ceRNA effect of it provides a critical mechanism of UBE2MP1, independent of its parental gene, in facilitating HCC cell growth and maintenance via modulating the miR-145-5p/RGS3 axis.
