MYB and breast carcinoma: Then, we investigated whether there was a correlation between NLK and c-MYB expression and found that high NLK levels (Fig. 1E) were correlated with low c-Myb levels (Fig. 1F) in the same breast carcinoma specimen (grade I); furthermore, low NLK levels (Fig. 1I) were correlated with high c-Myb levels (Fig. 1J) in the same breast carcinoma specimen (grade III).
