The migration and invasion capacities of JEG3 cells are more significantly suppressed by TET1 knockdown in cells exposed to 3% O2 than in cells exposed to 21% O2. (A,B) Real-time q PCR and western blot analyses showing the specific knockdown of TET1 in JEG3 cells by shRNA. (C) The migration and invasion capacities of JEG3 cells transfected with scramble shRNA or TET1 shRNA and then exposed to 21% or 3% O2 were assessed using the transwell assay. (D) The migrated or invaded cells were counted and the quantitative data are expressed as the fold change from the control of three independent experiments. (*P < 0.05, **P < 0.01, shCtrl vs. shTET1; ##P < 0.01 compared to shCtrl in 21% O2; there was no significant difference between the shTET1 cells exposed to 3% and 21% O2, one-way ANOVA) (E) Proliferation capacity of JEG3 cells transfected with scramble shRNA or TET1 shRNA and then exposed 3% O2. (P = 0.0.84, between the shCtrl cells exposed to 3% and 21% O2, one-way ANOVA).
