The overexpressed CCNDBP1 could inhibit the proliferation of breast cancer cell line MCF-7 (23) and NSCLC cell line H1299 (24), while the decrease in CCNDBP1 stability could accelerate the proliferation, migration, and invasion of lung cancer cell line and gastric cancer cell line (25). This evidence concerns the gene CCNDBP1 and breast carcinoma.
