Immunostaining confirmed the stimulation of postn in peri-tumoral infiltrating cells in PC3-ERRα bone lesions (Figure 7B, a versus b), in PC3c-ERRα bone lesions (Figure 7C, a versus b) and in peri-tumoral cells in PC3-ERRα SC tumor versus PC3-CT SC tumors (Supplementary Figure S1A a versus b). Here, ESRRA is linked to neoplasm.
