Regulatory mechanism of Scutellaria baicalensis Georgi on bone cancer pain based on network pharmacology and experimental verification

Abstract

Context Scutellaria baicalensis Georgi (SBG) may relieve bone cancer pain (BCP) by regulating cell proliferation, angiogenesis, and apoptosis. Objective The mechanism of SBG in the treatment of BCP remains to be further explored. Methods The active compounds and targets of SBG were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and SwissTargetPrediction databases. BCP-related targets were screened from NCBI and GeneCards databases. Additionally, Cytoscape software was applied to construct network diagrams, and OmicShare platform was used to enrich Gene Ontology (GO) and pathways. Finally, the verification of active compounds and core targets was performed based on quantitative real-time PCR (qRT-PCR). Results Interestingly, we identified baicalein and wogonin as the main active components of SBG. A total of 41 SBG targets, including VEGFA, IL6, MAPK3, JUN and TNF, were obtained in the treatment of BCP. In addition, pathways in cancer may be an essential way of SBG in the treatment of BCP. Experimental verification had shown that baicalein and wogonin were significantly related to BCP core targets. Conclusions The active components of SBG have been clarified, and the mechanism of the active components in treating BCP has been predicted and verified, which provides an experimental and theoretical basis for the in-depth elucidation of the pharmacodynamics material basis and mechanism of SBG.
