ZFP36 and posterior cortical atrophy: The cell proliferation test results (CCK-8 assay) indicated that tumor cells were significantly decreased after ZFP36 overexpression versus control, implying that ZFP36 could regulate proliferation of PCa tumor cells (Figures 2(e) and 2(h)); then, we performed cell scratch and cell invasion experiments, indicating that overexpression of ZFP36 could greatly suppress migration and invasion of tumor cells versus control (Figures 2(f), 2(i), 2(g), and 2(j)).
