A model combining two cancer-related glycoproteins (THBS1 and CTSD) and %fPSA can improve PCa diagnosis and may reduce the number of unnecessary prostate biopsies because of its improved specificity for PCa when compared to %fPSA alone.
Conclusively, the use of CTSD and THBS1 together with commonly used parameters for PCa diagnosis such as %fPSA and age has the potential to improve the diagnosis of PCa.
Identification of genes potentially involved in the acquisition of androgen-independent and metastatic tumor growth in an autochthonous genetically engineered mouse prostate cancer model.
Compared with the LNCaP/pcDNA3.1 and LNCaP cells, the expression of vimentin, cathepsin D, MMP-2 and uPAR were up-regulated in LNCaP/HIF-1alpha, whereas the expression of E-cadherin was down-regulated.
Although this study did not find independent prognostic status for cathepsin D in prostate cancer, the correlation with tumor grade and DNA ploidy status is noteworthy and the inter-relationship of outcome variables may prove of interest and warrant further evaluation of this potential predictor or CO-predictor of disease outcome.
