DUSP4 and hepatocellular carcinoma: Likewise, the newly identified interaction between mir-122-5p and DUSP2 should be the subject of future studies since a significant negative correlation was found in hepatocellular carcinoma while miR-122-5p is primarily regarded as a liver-specific tumour suppressor i.a. by downregulation of DUSP4 (Table 2) [106, 107].
