原始语种摘要: Prostate cancers (PRCAs) frequently metastasize to bone. We show here that this process is facilitated by osteoblast-mediated tumor cell recruitment. Transforming growth factor-beta1 (TGF-beta1) is produced by osteoblasts in a latent form and is activated by proteases in a cell-dependent manner. This cytokine exhibits pleiotropic effects on cell-extracellular matrix (ECM) interactions and may influence tumor cell invasion and metastasis. Our purpose was to identify the potential molecular mechanisms involved in osteoblast-mediated cell recruitment and to characterize the effect of TGF-beta1 on adhesion, motility and invasiveness of a human prostate cancer cell line with high bone metastatic potential (PC3 cell line) in vitro. Conditioned media from osteoblast cultures (OB CM) enhanced PC3...
