In normal tissues, a strong signal is observed in testis, weak signals in brain, kidney, trachea, uterus, and prostate (a); all other tissues tested are negative. (b) and (c) NW-BR-3 expression in several tumors and tumor cell lines. ZR-75-1, MCF 7, SK-BR-3, and Cama are breast cancer cell lines; CRL 10995 is a prostate cancer cell line; Asc-1, SK OV-3, and NW0192 - NW0049 are ovarian cancer cell lines. Abbreviations: BC, breast cancer; MEL, melanoma; OC, ovarian cancer; PC, prostate cancer; RC, renal cancer; TCC, transitional cell cancer.
