ABSTRACT
OBJECTIVE@#To investigate the expression of ZNF652 in breast cancer tissues and cells and explore its role in breast cancer cell proliferation, invasion and migration.@*METHODS@#We exploited the data from the TCGA database to analyze the differential expression of ZNF652 in breast cancer tissues and adjacent tissues and the correlations of ZNF652 expression with the clinicopathological characteristics of breast cancer patients including molecular subtypes, pathological types, TNM stages and clinical stages. RT-qPCR and Western blotting were used to detect the expression of ZNF652 in 5 breast cancer cell lines including MCF-7, MDA-MB-231, SK-BR-3, UACC-812 and BT-474. Using a lentivirus system and siRNA technique, we assessed the effects of ZNF652 over-expression and knockdown on proliferation, colony forming ability, migration and invasion of breast cancer cells with CCK-8 assay, clonogenic assay, Transwell assay and wound healing assay. The subcellular localization of ZNF652 in 293T cells was determined using immunofluorescence assay.@*RESULTS@#ZNF652 was significantly up-regulated in breast cancer tissues (@*CONCLUSIONS@#ZNF652 is highly expressed in breast cancer tissues and cells to promote the development and progression of breast cancer and may serve as a potential molecular target for diagnosis and treatment of the malignancy.
