Abstract
<jats:title>Abstract</jats:title> <jats:p>Introduction: Prostate carcinoma (PCa) is the most common cancer in men. The therapeutic effect of approved compounds, such as docetaxel, is limited due to the development of therapy resistance, making new treatment options essential. Artesunate (ART), used in Traditional Chinese Medicine, has shown anti-tumor activity in several tumor types. However, little is known about the efficacy of ART on therapy-resistant PCa. Therefore, the impact of ART on docetaxel-resistant PCa cells was investigated.</jats:p> <jats:p>Material and Methods: Parental (=sensitive) and docetaxel-resistant PCa cell lines, PC3, DU145, and LNCaP, were exposed to ART [1-100 µM] for 24, 48, or 72 hours. Cells not exposed to ART served as controls. Tumor cell growth, proliferation, cell cycling, and the expression of cell cycle regulating proteins were assessed. Apoptotic, ferroptotic, and necrotic effects were also evaluated.</jats:p> <jats:p>Results: Exposure to ART significantly reduced tumor cell growth and proliferation of parental and docetaxel-resistant PCa cells in a time- and dose-dependent manner. Cell cycle arrest in the G0/G1 phase after 48h exposure to 37.5 µM ART was observed in parental LNCaP and in all three resistant cell lines. The observed changes in cell growth and cell cycle phases were accompanied by marked modulation of cell cycle regulating proteins. Significant apoptotic effects were observed in parental PC3 and both parental and resistant LNCaP, whereas ferroptosis was apparent in parental and resistant DU145 after exposure to ART. Necrotic events were not detectable in the PCa cells after ART exposure.</jats:p> <jats:p>Conclusion: ART induced anti-tumor effects, though differing according to the cell line, were apparent in not only parental but also in docetaxel-resistant PCa cells. Thus, adding ART to standard therapies might be a promising treatment strategy for patients with advanced prostate cancer. Further investigations are necessary to verify our findings.</jats:p> <jats:p>Citation Format: Vitus Braeunig, Patricia Schupp, Sascha Markowitsch, Olesya Vakhrusheva, Holger Erb, Thomas Efferth, Axel Haferkamp, Eva Juengel.
