“…However, recent studies have revealed that at least some members of the transposable element families are transcriptionally active and may be capable of causing human cancers through several mechanisms. The association of transposable elements with breast cancer (Wang-Johanning et al, 2003b), melanoma (Buscher et al, 2005), seminoma (Rakoff-Nahoum et al, 2006), germ cell tumors (Galli et al, 2005), leukemia (Depil et al, 2002), ovarian carcinomas (Menendez et al, 2004), and prostate adenocarcinoma (Wang-Johanning et al, 2003a) has been suggested. Therefore, transposable elements may play a biological role in cancer development or organismal complexity by introducing transcriptional diversity .…”
