Currently, radiotherapy is a popular treatment for prostate cancer patients, but radioresistance is still a challenge. CDC20 has been shown to play a crucial role in various tumors, including prostate cancer. Higher expression of CDC20 was observed in prostate cancer tissues and cells. Knockdown of CDC20 inhibited cell proliferation, migration, tumor formation, induced cell apoptosis, and increased radiosensitivity in prostate cancer both in vitro and in vivo. CDC20 was found to regulate the Twist1 pathway, influencing cell proliferation and migration. Targeting CDC20 and Twist1 may be an effective approach to improve the radiosensitivity of prostate cancer.
Currently, radiotherapy is one of the most attractive treatments for prostate cancer (PCa) patients. However, radioresistance remains a challenging issue and the underlying mechanism is unknown. Growing evidence has demonstrated that CDC20 (Cell division cycle protein 20) plays a pivotal role in a variety of tumors, including PCa. Here, GEPIA database mining and western blot analysis showed that higher expression of CDC20 was observed in PCa tissues and cells. We demonstrated that the expression of CDC20 was increased in PCa cells by irradiation, and knockdown of CDC20 resulted in inhibition of cell proliferation, migration, tumor formation, induced cell apoptosis and increased radiosensitivity in PCa in vitro and in vivo. Furthermore, we observed that CDC20 regulated Twist1 pathway, influencing cell proliferation and migration. These results suggest that targeting CDC20 and Twist1 may be an effective way to improve the radiosensitivity of PCa.
