Overexpression of YTHDF2 significantly inhibited the proliferation, invasion and migration of gastric cancer cells by negatively regulating forkhead box C2 (FOXC2), which acts as an oncogene in various cancers such as nasopharyngeal cancer, colorectal cancer and triple negative breast cancer (71, 83–85). Here, FOXC2 is linked to triple-negative breast carcinoma.
