Knockdown of PLOD2 inhibits cell migration and invasion. a Knockdown of PLOD2 in HeLa and SiHa cells. Cells were transfected with si-scramble or siPLOD2 and then subjected to a Western blot analysis and qRT-PCR; α-tubulin and GAPDH were used as loading controls, respectively. b, d Depletion of PLOD2 inhibited cell migration and invasion. Si-scramble and siPLOD2 cells were subjected to transwell migration (b) and matrigel-coated invasion assays (d). Photos were captured under an ×200 objective lens. c, e Statistical analysis of migration (c) and invasion (e) based on the mean ± SD of at least three independent experiments. p values were obtained using Student’s t test. p < 0.05 is indicated by “**”, and p < 0.001 is indicated by “***”, si-scramble versus siPLOD2-s2 or siPLOD2-s4. f Scratch assays corroborated the decrease in HeLa and SiHa cell migration after the knockdown of PLOD2. Images were captured at ×200 magnification. g Statistical data were obtained as described above
