Similar to previous studies in both gastric (Krieg et al, 2002) and renal carcinomas (Mahotka et al, 2002a) as well as breast cancer (O'Driscoll et al, 2003), we show here that full-length survivin is also the main form of survivin expressed in normal breast tissue, fibroadenomas and breast carcinomas. This evidence concerns the gene BIRC5 and renal carcinoma.
