The results demonstrated that: i) PCPH is expressed in TGCT cell lines and tumors, including CIS; ii) its expression levels vary among different TGCT pathologies, being generally higher in well differentiated regions and lower in areas of predominant proliferation; iii) PCPH expression is substantially increased in tumors relative to matched normal testicular tissue; iv) tumor samples express PCPH polypeptides of low molecular mass, consistent with the known size of the PCPH oncoprotein, that are either absent from, or markedly reduced in, matched normal tissue.
