Biomarker Discovery and Molecular Docking Reveal Marsdenia tenacissima Fermentation Product's Anti-Lung Cancer Components.

Metadata-grounded summary

Citation abstract

In traditional Chinese medicine, Marsdenia tenacissima is employed to prevent and treat lung cancer. The anti-tumor properties are further amplified by the fermentation product of Ganoderma lucidum and Marsdenia tenacissima (MGF). Nevertheless, the efficacy of the chemical components in combating lung cancer and the potential therapeutic targets for treating the disease remain ambiguous. UPLC-Q-TOF/MS was used to identify 19 components, all of which are unique C 21 steroidal saponins found in MGF. The analysis of network pharmacology indicated that the active targets of these components were significantly concentrated in lung cancer and had a strong connection with cell proliferation. The bioinformatics analysis was conducted on data from TCGA and DisGeNET to identify a total of 28 biomarkers. Furthermore, our findings showed that the 19 targets connected to the active ingredients of Marsdenia tenacissima demonstrated significant enrichment in both the EGFR and apoptosis signaling pathways. Molecular docking technology was utilized to confirm the binding interactions of the primary constituents with the designated target.
