Figure 4: Repressive impact of sh-VPS9D1-AS1 on phenotype progression is rescued by downregulating miR-187-3p. (a) qRT-PCR was done to test miR-187-3p level in PC-3 cells in 3 groups (sh-NC + NC-inhibitor, sh-VPS9D1-AS1 + NC-inhibitor, and sh-VPS9D1-AS1 + miR-187-3p-inhibitor). (b) MTT assay detected the proliferative capacity of PC-3 cells in 3 groups. (c) Colony formation assay was carried out to examine the colony formation ability of PC-3 cells in 3 groups. (d) Wound healing assay was launched to assess the migratory property of PC-3 cells in three groups (magnification: ×40). (e) Cell invasion assay estimated the invasive property of PC-3 cells in 3 groups (magnification: ×100). *P < 0.05 relative to sh-NC + NC-inhibitor group, #P < 0.05 relative to sh-VPS9D1-AS1 + NC-inhibitor group, n = 3. NC: Negative controls.
