To determine whether PCAT7 serves as a bone metastasis‐related lncRNA in PCa, an in vivo bone metastasis model was employed, in which the PCAT7‐overexpressing, PCAT7‐downregulated, and corresponding control PC‐3 cells labeled with luciferase were directly inoculated into the left cardiac ventricle of nude mice (Fig. S2a). The gene discussed is PCAT7; the disease is posterior cortical atrophy.
