Sequencing of the aforementioned three cloned RAPD fragments from human breast cancer tissue revealed that clone 10-1 consisted of 1027 nucleotides is located in the intron of DPEP1 transcript variant 2, and overlapped DPEP1 (dipeptidase 1) transcript variant 1 in GenBank (NM_004413) (Figure 3A and Figure 4A). This evidence concerns the gene DPEP1 and breast cancer.
