BCL6 and cancer: Aberrant expression of miR‐127 is reported in several cancer types such as hepatocellular carcinoma, ovarian carcinoma, and gastric cancer.24, 25, 26 miR‐127 is a tumor suppressor which regulates BC cell proliferation and senescence by targeting BCL6. Chen et al27 showed that miR‐127 was down‐regulated and its lower expression leads to the up‐regulation of BCL6 in BC tissues.
