TNFRSF11A and posterior cortical atrophy: Relative expression levels of RANKL, RANK, and OPG in LNRANKL and control neo-transfected LNNeo cells, ARCaPE, and ARCaPM are shown in Fig. 2A. To test the possibility that RANKL expression in PCa cells confers bone metastasis in mice, 1×106 LNRANKL-Luc or control LNNeo-Luc cells were injected intracardially into mice.
