Abstract
Patients with advanced-stage cancers often suffer from severe pain caused by bone metastasis and destruction, for which effective treatment options are limited. Liu-Shen-Wan (LSW) is a widely recognized herbal formula utilized for pain relief. This study aims to elucidate the effects of LSW on bone cancer pain (BCP). In this study, the pharmacology of LSW on BCP was screened by network pharmacology. A BCP model was conducted using Walker 256 cells. Paw withdrawal threshold and paw withdrawal latency were employed as measures to assess the pain threshold in rats. The pathways and cell types of LSW against BCP were explored. Next, the impact of LSW on Walker 256 cells was evaluated, and UPLC-MS was utilized to identify the active ingredients of LSW. Furthermore, the effects of the key active ingredient, Bufalin, on the BCP rats were evaluated. There were 275 shared targets between LSW and BCP, which were enriched in neural tissue ligand-receptor interaction pathway. LSW increased pain threshold and decreased inflammatory cytokines levels in BCP rats by inhibiting PI3K/Akt and transient receptor potential vanilloid 1 (TRPV1) signaling through astrocytes and microglia. LY294002 further alleviated BCP in rats, while the effects were reversed after treatment with insulin-like growth factor 1 (IGF-1). Both LSW and its active ingredient Bufalin were shown to inhibit the viability and migration of Walker 256 cells and induce apoptosis. Bufalin appears to be the key active ingredient of LSW and exerts its pain-relieving effects by suppressing PI3K/Akt and TRPV1 signaling in BCP.
期刊介绍：
Cancer, the second leading cause of death, is a heterogenous group of over 100 diseases. Cancer is characterized by disordered and deregulated cellular and stromal proliferation accompanied by reduced cell death with the ability to survive under stresses of nutrient and growth factor deprivation, hypoxia, and loss of cell-to-cell contacts. At the molecular level, cancer is a genetic disease that develops due to the accumulation of mutations over time in somatic cells. The phenotype includes genomic instability and chromosomal aneuploidy that allows for acceleration of genetic change. Malignant transformation and tumor progression of any cell requires immortalization, loss of checkpoint control, deregulation of growth, and survival. A tremendous amount has been learned about the numerous cellular and molecular genetic changes and the host-tumor interactions that accompany tumor development and progression. It is the goal of the field of Molecular Oncology to use this knowledge to understand cancer pathogenesis and drug action, as well as to develop more effective diagnostic and therapeutic strategies for cancer. This includes preventative strategies as well as approaches to treat metastases. With the availability of the human genome sequence and genomic and proteomic approaches, a wealth of tools and resources are generating even more information. The challenge will be to make biological sense out of the information, to develop appropriate models and hypotheses and to translate information for the clinicians and the benefit of their patients. Cancer Biology & Therapy aims to publish original research on the molecular basis of cancer, including articles with translational relevance to diagnosis or therapy. We will include timely reviews covering the broad scope of the journal. The journal will also publish op-ed pieces and meeting reports of interest. The goal is to foster communication and rapid exchange of information through timely publication of important results using traditional as well as electronic formats. The journal and the outstanding Editorial Board will strive to maintain the highest standards for excellence in all activities to generate a valuable resource.
