Figure 2From: ERK/pERK expression and B-raf mutations in colon adenocarcinomas: correlation with clinicopathological characteristicsSchematical representation of the association between nuclear pERK expression and histological grade. Tumors with grade II/III tended to display higher pERK nuclear immunoreactivity compared to those with grade I (p = 0.0113, Mann- Whitney U test).Back to article page
