Compared to the human prostate cancer cell lines, the murine prostate cancer cell line Myc-CaP seemed to have lower migration rates, as evidenced by the fact that they failed to completely close the wound before they started to grow again around the 32 hour time point (data not shown), regardless of the status of ERBB2- or RAS-overexpression (Figure 3). The gene discussed is ERBB2; the disease is prostate carcinoma.
