Bpag1, tbc1d13 and c7orf30 were expressed at much higher levels in F10 melanoma cells (7.0-, 3.1- and 1.9-fold, respectively) and F10 melanoma tumors (10.9-, 4.2- and 6.3-fold, respectively) as compared to NIH-3T3 cells (Figure 2C); the expression levels of the remaining 5 candidates in melanoma cells and tumors were less than the expression level in NIH-3T3 cells (data not shown). The gene discussed is TBC1D13; the disease is melanoma.
