The objective of this study was to examine the potential of CRISP-3 as a biomarker for prostate cancer. In transient transfection studies, CRISP-3 was found to be a secretory protein. Using a multiple tissue dot blot experiment, CRISP-3 transcript was identified in a limited number of human tissues including the prostate. In situ hybridization experiments indicated that CRISP-3 mRNA is epithelial-specific and is up-regulated in prostate adenocarcinoma compared with benign prostate tissue. CRISP-3 mRNA overexpression in cancer was confirmed using quantitative real-time reverse-transcription-PCR using benign prostatic epithelia and adenocarcinoma (in 5 of 5 cases) isolated by laser capture microdissection, as well as bulk tissues (in 20 of 23 cases) from surgically resected human prostates. These findings suggest that CRISP-3 is a potential biomarker for prostate cancer.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":241,"end":256},"obj":"HP_0012125"},{"id":"T2","span":{"begin":250,"end":256},"obj":"HP_0002664"},{"id":"T3","span":{"begin":406,"end":421},"obj":"HP_0012125"},{"id":"T4","span":{"begin":415,"end":421},"obj":"HP_0002664"},{"id":"T5","span":{"begin":844,"end":850},"obj":"HP_0002664"},{"id":"T6","span":{"begin":1184,"end":1199},"obj":"HP_0012125"},{"id":"T7","span":{"begin":1193,"end":1199},"obj":"HP_0002664"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"},{"subj":"T2","pred":"source","obj":"PubmedHPO"},{"subj":"T3","pred":"source","obj":"PubmedHPO"},{"subj":"T4","pred":"source","obj":"PubmedHPO"},{"subj":"T5","pred":"source","obj":"PubmedHPO"},{"subj":"T6","pred":"source","obj":"PubmedHPO"},{"subj":"T7","pred":"source","obj":"PubmedHPO"}]},{"project":"DisGeNET5_gene_disease","denotations":[{"id":"12433721-0#0#33#gene10321","span":{"begin":0,"end":33},"obj":"gene10321"},{"id":"12433721-0#61#76#diseaseC0376358","span":{"begin":61,"end":76},"obj":"diseaseC0376358"},{"id":"12433721-0#61#76#diseaseC0600139","span":{"begin":61,"end":76},"obj":"diseaseC0600139"},{"id":"12433721-5#49#56#gene10321","span":{"begin":692,"end":699},"obj":"gene10321"},{"id":"12433721-5#108#131#diseaseC0007112","span":{"begin":751,"end":774},"obj":"diseaseC0007112"},{"id":"12433721-6#0#7#gene10321","span":{"begin":813,"end":820},"obj":"gene10321"},{"id":"12433721-6#144#158#diseaseC0001418","span":{"begin":957,"end":971},"obj":"diseaseC0001418"}],"relations":[{"id":"0#33#gene1032161#76#diseaseC0376358","pred":"associated_with","subj":"12433721-0#0#33#gene10321","obj":"12433721-0#61#76#diseaseC0376358"},{"id":"0#33#gene1032161#76#diseaseC0600139","pred":"associated_with","subj":"12433721-0#0#33#gene10321","obj":"12433721-0#61#76#diseaseC0600139"},{"id":"49#56#gene10321108#131#diseaseC0007112","pred":"associated_with","subj":"12433721-5#49#56#gene10321","obj":"12433721-5#108#131#diseaseC0007112"},{"id":"0#7#gene10321144#158#diseaseC0001418","pred":"associated_with","subj":"12433721-6#0#7#gene10321","obj":"12433721-6#144#158#diseaseC0001418"}],"attributes":[{"subj":"12433721-0#0#33#gene10321","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-0#61#76#diseaseC0376358","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-0#61#76#diseaseC0600139","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-5#49#56#gene10321","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-5#108#131#diseaseC0007112","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-6#0#7#gene10321","pred":"source","obj":"DisGeNET5_gene_disease"},{"subj":"12433721-6#144#158#diseaseC0001418","pred":"source","obj":"DisGeNET5_gene_disease"}]},{"project":"CoMAGC","denotations":[{"id":"T1","span":{"begin":207,"end":214},"obj":"Gene"},{"id":"E2","span":{"begin":225,"end":237},"obj":"Positive_regulation"},{"id":"T2","span":{"begin":241,"end":256},"obj":"prostate
