(A–B) Examine the apoptosis of CD8+ T cells after co-cultured with U2OS miR-200a control or miR-200a OE separately. (C–D) Examine the proliferation rate of CD8+ T cells after co-cultured with U2OS miR-200a control or miR-200a OE separately. (E–F) Enzyme-Linked ImmunoSorbent Assay (ELISA) of the secretion of granzyme B and perforin. *P<0.05, **P<0.01, ***P<0.001.
