CCND1 and gastric cancer: CCND1 stimulates G1 progression in responding to growth factor stimulation 27; miR‐211 down‐regulation results in CCND1 and CDK6 overexpression, which increases the proliferative ability of EOC cells 28.SMARCD1, whose high expression predicts poorer prognosis in gastric cancer, functions as an oncogene by promoting gastric cancer cell proliferation, migration and invasion 29.
