Abstract

Carpesium cernuum L. is a traditional medicine primarily used in Southwestern China, and it has been shown to exhibit a range of biological properties, including anti‑inflammatory and antitumor activities. Incaspitolide A (IA) is a sesquiterpene isolated from C. cernuum L. The aim of the present study was to investigate the antiproliferative effects of IA on PC‑3 prostate cancer cells and determine the underlying mechanism. Results from a Cell Counting Kit‑8 assay demonstrated that IA significantly reduced the numbers of viable PC‑3 cells in a time and dose‑dependent manner. Phase‑contrast microscopy revealed that the number and morphology of cells were markedly altered. Hoechst and EdU staining assays showed that IA reduced the proliferation of PC‑3 cells. Flow cytometry analysis revealed that IA arrested cell cycle progression at the S phase and promoted cell apoptosis in a dose‑dependent manner. Western blot analysis demonstrated that treatment with IA resulted in downregulation of phosphorylated (p‑) PI3K, p‑Akt, X‑linked inhibitor of apoptosis (xIAP), CKD2, cyclin A2 and pro‑Caspase‑3 protein expression, and upregulation of cleaved poly(ADP‑ribose) polymerase and P53 expression. The present results suggested that IA inhibited the growth of PC‑3 cells and induced apoptosis. The underlying mechanism appeared to involve the inhibition of the PI3K/Akt/xIAP pathway. The present study indicated that IA may serve as a therapeutic for the management of prostate cancer and provided a theoretical basis for the pathogenesis of prostate cancer.
