Consistent with published reports in human melanoma, Dicer expression in B16F0 (non-metastatic) and B16F10 (metastatic) was significantly higher compared to the 4T1 and CT26 cell lines and was also significantly elevated relative to normal murine melanocytes (Melan A) (Figure 1) [22, 23]. The gene discussed is DICER1; the disease is melanoma.
