KDM3A and lung cancer: Moreover, compared with the cells transfected with si‐KDM3A + oe‐NC, there was no significant change observed in KDM3A expression in cells transfected with si‐KDM3A + oe‐DCLK1, whereas DCLK1 expression was increased and lung cancer cell proliferation, migration and invasion were remarkably increased (Figure 4H‐K).
