DUSPs as markers of MEK/Erk activation in primary colorectal cancer.


4064 Background: DUSPs dephosphorylate P-MAPK and are activated as a negative feedback loop upon RTK signaling. Higher expression of DUSP 4 & 6 is also found in cells with constitutive Erk activation like KRAS mutant (MUT) cells (Bild et al. Nature 2005). We correlated DUSP1, 4, 6 (isoforms a & b) & 8 mRNA expression level in FFPE primary colorectal cancer… (More)
