Figure 2. Upregulation of miR-34a inhibits proliferation, migration and invasion in TCP-1 cells. miR-34a mimics and its negative control (NC) was transfected into TCP-1 cells. (A) The expression of miR-34a was determined by qRT-PCR (*p < 0.05). (B) CKK-8 assay was used to examine the cell growth at 0, 24, 48 and 72 h (*p < 0.05). (C) Colony formation assay was used to calculated cell proliferation (*p < 0.05). (D) Wound healing assay was used to detect cell migration (*p < 0.05). (E) Transwell assay was performed to check cell invasive ability (*p < 0.05).
