Reciprocal cross-talk between Prostaglandin E2 and bone in prostate cancer: a current review


, : Reciprocal cross-talk between Prostaglandin E2 and bone in prostate cancer: a current review. Central European Journal of Urology 64(4): 201-204

In this review we analyzed the role of PGE2 as a possible regulator of bone metabolism and bone metastases in prostate cancer. Published studies were identified by searching computerized bibliographic systems from January 1(st), 2000 to July 1(st), 2011. PGE2 represents a key factor in the modulation of bone metabolism and bone metastatic disease in prostate cancer interacting with bone regulatory signals including the RANK/RANKL/OPG system and Wnt pathways. A high concentration of PGE2 exerts a prevalent stimulatory effect on osteoclastogenesis via OPG/RANK/RANKL axis activation and a inhibitory effect on osteoblastogenesis trough inhibition of Wnt pathway. An inversely low level of PGE2 exerts a stimulatory effect on osteoblastogenesis via activation of the Wnt pathway. Our finding suggests that PGE2 acts as a regulator in maintaining normal bone mass and indicate a mechanism whereby chemical manipulation of PGE2 levels or signaling may be therapeutically beneficial for prostate cancer treatment.

In this short paper, we suggest some concepts and methods that may be useful in considering a metabolomic approach to the study of amino acid adequacy and safety. We suggest that the analysis of a metabolomic subset, such as amino acids, may yield...

The symmetry breaking by reflection manifests itself by tipping the net-spi...
