Abstract

Cervical cancer is one of the most common malignant tumors in the female reproductive system. Radioresistance remains a significant factor that limits the efficacy of radiotherapy for cervical cancer. Interleukin‐11 (IL-11) has been reported to be upregulated in various types of human cancer and correlate with clinical stage and poor survival. However, the exact effects and mechanisms of IL-11 in the radioresistance of cervical cancer have not yet been defined. In this research, TCGA databases revealed that IL-11 expression was upregulated in cervical cancer tissues and was associated with clinical stages and poor prognosis in cervical cancer patients. We discovered that IL-11 concentration was significantly upregulated in radioresistant cervical cancer cells. Knocking down IL-11 in Hela cells could reduce clonogenic survival rate, decrease cell viability, induce G2/M phase block, and facilitate cell apoptosis. In contrast, Exogeneous IL-11 in C33A cells could upregulate clonogenic survival rate, increase cell viability, curb G2/M phase block, and cell apoptosis. Mechanistic investigations showed that radioresistance conferred by IL-11 was attributed to the activation of the PI3K/Akt signaling pathway. Altogether, our results demonstrate that IL-11 might be involved in radioresistance, and IL-11 may be a potent radiosensitization target for cervical cancer therapy.
