It was reported that silencing CCNB1IP1 in gastric cancer cells U2OS and breast cancer cells MCF‐7 promoted cell metastasis and invasion, but suppressed cell proliferation and growth, suggesting that the extent or nature of CCNB1IP1 being required in different biological behaviours of tumour cells may not be consistent.18 The gene discussed is CCNB1IP1; the disease is breast carcinoma.
