Project description:BackgroundCondyloma acuminatum (CA) is a sexually transmitted disease characterized by the anomalous proliferation of keratinocytes caused by human papillomavirus (HPV) infection. Fu Fang Gang Liu liquid (FFGL) is an effective externally administered prescription used to treat CA; however, its molecular mechanism remains unclear. This study aimed to identify and experimentally validate the major active ingredients and prospective targets of FFGL.MethodsNetwork pharmacology, transcriptomics, and enrichment analysis were used to identify the active ingredients and prospective targets of FFGL, which were confirmed through subsequent experimental validation using mass spectrometry, molecular docking, western blotting, and in vitro assays.ResultsThe network pharmacology analysis revealed that FFGL contains a total of 78 active compounds, which led to the screening of 610 compound-related targets. Among them, 59 overlapped with CA targets and were considered to be targets with potential therapeutic effects. The protein-protein interaction network analysis revealed that protein kinase B (Akt) serine/threonine kinase 1 was a potential therapeutic target. To further confirm this result, we performed ribonucleic acid sequencing (RNA-seq) assays on HPV 18+ cells after FFGL exposure and conducted enrichment analyses on the differentially expressed genes that were screened. The enrichment analysis results indicated that the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway may be a key pathway through which FFGL exerts its effects. Further in vitro experiments revealed that FFGL significantly inhibited the activity of HPV 18+ cells and reduced PI3K and Akt protein levels. A rescue experiment indicated that the reduction in cell viability induced by FFGL was partially restored after the administration of activators of the PI3K/Akt pathway. We further screened two active components of FFCL that may be efficacious in the treatment of CA: periplogenin and periplocymarin. The molecular docking experiments showed that these two compounds exhibited good binding activity to Akt1.ConclusionFFGL reduced HPV 18+ cell viability by inhibiting key proteins in the PI3K/Akt pathway; this pathway may represent an essential mechanism through which FFGL treats CA. Periplogenin and periplocymarin may play a significant role in this process.
