UHRF1 knockdown induces cell cycle arrest and apoptosis in breast cancer cells through the ZBTB16/ANXA7/Cyclin B1 axis.

ABSTRACT: Ubiquitin-like containing PHD and RING finger domains 1 (UHRF1) is involved in tumorigenicity through DNA methylation in various cancers, including breast cancer. This study aims to investigate the regulatory mechanisms of UHRF1 in breast cancer progression. Herein, we show that UHRF1 is upregulated in breast cancer tissues and cell lines as measured by western blot analysis and immunohistochemistry. Breast cancer cells are transfected with a UHRF1 overexpression plasmid (pcDNA-UHRF1) or short hairpin RNA targeting UHRF1 (sh-UHRF1), followed by detection of cell proliferation, invasion, apoptosis, and cell cycle. UHRF1 overexpression promotes proliferation and invasion and attenuates cell cycle arrest and apoptosis in breast cancer cells, while UHRF1 knockdown shows the opposite eff
