OGFRP1 and posterior cortical atrophy: For transwell invasion assay, the number of cells that invaded Matrigel significantly decreased in the si-OGFRP1, miR-124-3p, and si-OGFRP1+miR-124-3p groups, suggesting that si-OGFRP1 and miR-124-3p both induced the inhibition of cell metastasis in PCa (Figure 4B).
