In our study, we showed that the expression level of the ABCA2, ABCA3, ABCB1, ABCB4, ABCB9, ABCC1, ABCC2, ABCC4, ABCC5, ABCC6, ABCC10, ABCC11, and ABCG2 genes was reduced in relation to the normal tissue surrounding the tumor (control) and only the average level of expression ABCC3 gene was elevated compared to controls (Figure 1 and Figure 2). The gene discussed is ABCC2; the disease is neoplasm.
