The invention provides SPANX polypeptides, nucleic acids and antibodies that are useful for detecting and treating cancer. The invention relates to a new subfamily of SPANX genes, SPANX-N1, SPANX-N2, SPANX-N3 SPANX-N4 and SPANX-N5. In contrast to the previously identified SPANX-A/D subfamily, expression of SPANX-N genes is not restricted to testis, and was detected in normal prostate, placenta, lung, colon, ovary and cervix tissues. Comparison of matched normal/tumor tissues revealed a predominant activation of only one member of the subfamily, SPANX-N1, in tumors, indicating that expression of this gene is diagnostic of cancer. Methods and reagents described herein permit detection and treatment of cancers associated with SPANX-N1 expression.

L'invention concerne des polypeptides, des acides nucléiques et des anticorps SPANX qui sont utiles pour détecter et traiter le cancer. L'invention concerne également une nouvelle sous-famille de gènes SPANX, les gènes SPANX-N1, SPANX-N2, SPANX-N3 SPANX-N4 et SPANX-N5. Contrairement à la sous-famille SPANX-A/D préalablement identifiée, l'expression de gènes SPANX-N n'est pas limitée au testicule, et a été détectée dans les tissus de la prostate, du placenta, du poumon, du côlon, de l'ovaire et du col de l'utérus normaux. La comparaison de tissus normaux/tumoraux correspondants a révélé une activation prédominante d'uniquement un élément de la sous-famille, le SPANX-N1, dans des tumeurs, indiquant que l'expression dudit gène est un élément de diagnostic du cancer. Les méthodes et réactifs selon l'invention permettent de détecter et de traiter des cancers associés à l'expression de SPANX-N1.
