Abstract

Objectives To investigate the expression of osteoprotegerin (OPG) and RANK ligand (RANKL) in human prostatic tissues. The factors regulating the increased turnover associated with prostate cancer (CaP) bone metastasis are unknown. OPG and RANKL are recently identified regulators of bone resorption and bone remodeling.Methods Tissues from 28 patients with CaP and from 4 normal organ donors were analyzed by reverse transcriptase-polymerase chain reaction and immunohistochemistry for the expression of OPG and RANKL.Results OPG and RANKL messages were detected in both normal and cancerous prostate samples. In the normal prostate, OPG protein was detected in luminal epithelial and stromal cells (5% to 65% and 15% to 70%, respectively) and RANKL immunoreactivity was observed in 15% to 50% of basal epithelial cells, 40% to 90% of luminal epithelial cells, and 70% to 100% of stromal cells. OPG was not detected in 8 of 10 primary CaP specimens; RANKL was heterogeneously expressed in 10 of 11 CaP specimens. The percentage of tumor cells expressing OPG and RANKL was significantly increased in all CaP bone metastases compared with nonosseous metastases or primary CaP.Conclusions CaP bone metastases were consistently immunoreactive for both OPG and RANKL compared with nonosseous metastases or primary CaP. The presence of these crucial bone resorption regulators in CaP bone metastases suggests a mechanism whereby CaP cells may modulate bone turnover and has profound implications for the establishment and development of CaP bone metastases in advanced disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
