A novel gene, designated UROC28, was identified by an agarose gel-based differential display technique, and it was found to be up-regulated in prostate, breast, and bladder cancer. Expression of UROC28 was also up-regulated in prostate cancer cells in the presence of androgens as demonstrated by relative quantitative reverse transcription-PCR. The elevated expression of this gene was observed to increase in surgically removed tissues concomitantly with rising Gleason grade and was most elevated in metastatic tissue. UROC28 protein was detected in serum by Western slot blot analyses, and a significant higher UROC28 protein level was found in sera of prostate cancer individuals compared with normal individuals and individuals with nonmalignant prostatic hyperplasia. Northern analyses in normal tissues showed that the UROC28 cDNA hybridizes to two mRNAs at about 2.1 and 2.5 kb. Nucleic acid sequence analyses indicated that these two alternatively spliced mRNA variants differ only at the 3' untranslated region. These two mRNAs encode the same protein with 135 amino acids. Bioinformation analyses suggest that there is a possible transmembrane domain from amino acid aa34 to aa50, three protein kinase-C phosphorylation sites at aa62 (SQK), aa89 (TMK), and aa94 (SMK), and one myristylation site at aa118 (GLECCL). Genomic Southern hybridization and chromosomal mapping demonstrated that UROC28 is encoded by a single copy of gene at chromosome 6q23-24. In situ hybridization and immunohistochemistry experiments further confirmed up-regulation of this gene in prostate and breast cancers with the expression localizing to the glandular epithelium. This gene did not demonstrate increased expression in lung and colon cancer tissues.
