In addition to activating dendritic cell mediated innate immune response by repressing DAPK2/SP1 pathway in gastric cancer [74], miR-34a also increases tumor-infiltrating CD8 expression T lymphocytes and decreases CD8/PD1 expression T lymphocyte by directly targeting PD-L1 3'-untranslated region [75]. Here, CD8A is linked to gastric cancer.
