Previous studies showed that the expression levels of eEF1A2 are elevated (Anand et al., 2002; Lee and Surh, 2009) and their genes (genomic region: 20q13) are amplified in a high proportion of solid tumors, such as ovarian (Iwabuchi et al., 1995) and breast cancers (Kallioniemi et al., 1994). This evidence concerns the gene EEF1A2 and breast cancer.
