Compared with the blank group (31.04% ± 0.86%), there were lower number of tumor spheres in the miR-542-3p mimics (19.86% ± 0.61%) and siRNA-ILK (21.18% ± 0.86%) groups, and increased number of tumor spheres in the miR-542-3p inhibitors group (51.31% ± 2.13%; all P < 0.05; Figure 5B). Here, ILK is linked to neoplasm.
