PCED1B and neoplasm: As shown in Figure 8a-c, knockdown of PCED1B-AS1 obviously inhibited the tumor growth, and miR-633 promoted tumor growth, while co-transfection of sh-PCED1B-AS1 and miR-633 inhibitor attenuated the protective role of sh-PCED1B-AS1 in tumor progression (p < 0.05 and p < 0.01, Figure 8a-c).
