DUSP9 and colorectal carcinoma: The results of MTS cell viability assay also showed that PD98059 treatment significantly decreased the growth of SW480 cells induced by DUSP9 knockdown, whereas Curcumin treatment significantly increased the growth of LoVo cells suppressed by DUSP9 overexpression, indicating that Erk activation is involved in the DUSP9 silencing-mediated tumor growth of CRC (Figure 7D).
