For instance, CD164 has been reported for the maintenance and progression of human tumors, such as human glioma,13 lung cancer,14 ovarian cancer,15 and prostate cancer.16 Besides, some microRNAs such as miR‐124 and miR‐219 were found that could suppress the proliferation, migration, and invasion of tumor cells by targeting CD164.17, 18 However, the roles of CD164 in BC have not yet been studied and are still unclear. The gene discussed is CD164; the disease is lung cancer.
