Abstract

Hirsuteine is extracted from Uncaria rhynchophylla, the bark of which has traditionally been used to treat hypertension, cancer, convulsions, hemorrhage, auto‑immune disorders, and other ailments. The anticancer properties of hirsuteine are of significant importance to the research community; however, its underlying mechanism of action is not well understood. The aim of the present study was to examine the antiproliferative ability of hirsuteine using human breast cancer MDA‑MB‑453 cells and to determine the underlying molecular mechanism involved in its therapeutic efficacy. The effects of hirsuteine on cell viability were determined using CCK‑8 and colony formation assays, while apoptosis was assessed using flow cytometry. Cell cycle distribution was assessed using flow cytometry, and apoptotic cell quantification was performed using via Annexin V‑FITC/PI staining and flow cytometry. Reverse transcription‑quantitative PCR and western blotting were used to assess the expression of cell cycle progression and apoptosis associated genes and proteins. MDA‑MB‑453 cell proliferation was significantly reduced by hirsuteine in a concentration and time‑dependent manner. Hirsuteine‑treated cells exhibited G2/M phase arrest, as evidenced by the increase in G2/M phase cells and a decrease in the G0/G1 phase cells, and this was related to cyclin B1 and CDK1 downregulation. Furthermore, hirsuteine accelerated MDA‑MB‑453 cell apoptosis by downregulating Bcl‑2 while upregulating cytoplasmic cytochrome c, Bax, Apaf1, cleaved caspase‑3, and cleaved caspase‑9 levels, which together drove apoptotic cell death. Thus, hirsuteine suppressed MDA‑MB‑453 cancer cell proliferation by inducing cell cycle arrest and promoting apoptosis.
