Prostate cancer, as one of the most prevalent malignant tumors in men, seriously affects the prognosis and survival of patients due to its extremely high rate of bone metastasis. This study investigated the effect of Polyphyllin VI (PPVI) on metastatic bone disease for the first time in prostate cancer, focusing on its impact on osteoclast and tumor cell. In vitro studies utilized TRAP staining, ghost pen cyclic peptide staining, and bone resorption assays to evaluate the differentiation and function of receptor activator of nuclear factor-κB ligand (RANKL) induced and RM-1 conditional medium (CM) induced osteoclasts.

Background: The development and maintenance of normal bone tissue is maintained by balanced communication between osteoblasts and osteoclasts. The invasion of cancer cells disrupts this balance, leading to osteolysis. As the only bone resorbing cells in vivo, osteoclasts play important roles in cancer-induced osteolysis.

Osteoblasts are the main functional cells of bone formation, and they are responsible for the synthesis, secretion, and mineralization of the bone matrix. Phosphatidylinositol-3-kinase/Akt is an important signaling pathway involved in the regulation of cell proliferation, death, and survival. Some studies have shown that 3-phosphoinositide-dependent protein kinase-1 (PDK-1) plays an important role in the phosphorylation of Akt.

The PI3K/AKT signaling pathway is strongly associated with the differentiation and survival of osteoblasts. The 3‑phosphoinositide‑dependent protein kinase‑1 (PDK‑1) protein is considered the master upstream lipid kinase of the PI3K/AKT cascade.

The osteoclast is the only cell in the body capable of resorbing and degrading the mineralized bone matrix. Osteoclast formation from monocytic precursors is governed by the actions of two key cytokines macrophage-colony-stimulating factor and receptor activator of nuclear factor-κB ligand (RANKL).

Studies have shown that miRNAs regulate the processes related to osteoporosis, including the differentiation of osteoblasts, osteoclasts, and chondrocytes, and are one of the important regulatory factors of some bone metabolic diseases. In our previous study, it has been revealed that natural compound polysaccharide (PSP) can promote osteoblast formation and block osteoclastogenesis through Wnt/β-catenin signaling pathway.
