miR-371-5p down-regulates pre mRNA processing factor 4 homolog B (PRPF4B) and facilitates the G1/S transition in human hepatocellular carcinoma cells

► miR-371 down-regulates pre mRNA processing factor 4 homolog B (PRPF4B). ► miR-371-5p promotes and PRPF4B suppresses the G1/S transition of cell cycle. ► The expressions of miR-371-5p and PRPF4 are deregulated in human hepatoma cells.
