CD8A and acute myeloid leukemia: The targeting relationship between miR-128-3p and circ-RERE or ZEB1 was verified.<h4>Results</h4>As detected, suppressing circ-RERE or overexpressing miR-128-3p significantly blocked the proliferation, migration, invasion, and autophagy of AML cells, promoted cell apoptosis, suppressed PD-L1 expression, and increased CD8+ T-cell cytotoxicity.
