Solanum nigrum L.'s active component solasodine targets ABCB1 to overcome docetaxel resistance in prostate cancer
To explore whether solasodine, an active component
of
Solanum nigrum
L., can target ATP binding cassette subfamily B member 1 (ABCB1) to overcome docetaxel resistance in prostate cancer and to elucidate its mechanism of action.
Methods
2
The active components and target genes of
Solanum nigrum
L. were analyzed by network pharmacology. The interaction between solasodine and ABCB1 was assessed using molecular docking. The effect of solasodine on docetaxel resistance in prostate cancer cells was detected by thiazole blue (MTT) assay. The effects of solasodine on ABCB1 expression, localization, protein kinase B (Akt) and extracellular regulatory protein kinase (ERK) pathways were detected by Western blot and immunofluorescence. Additionally, the effects of solasodine on drug accumulation and efflux were detected by flow cytometry.
Results
2
Network pharmacological analysis result showed that the therapeutic effect of solasodine on prostate cancer were potentially associated with ABCB1. Molecular docking result revealed that solasodine could bind stably to ABCB1. MTT assay result demonstrated that solasodine could overcome docetaxel resistance by targeting ABCB1. Western blot and immunofluorescence results showed that solasodine did not affect ABCB1 expression and localization, nor did it affect Akt and ERK signaling pathways. Flow cytometry result showed that solasodine overcame docetaxel resistance by inhibiting ABCB1 efflux and increasing intracellular drug accumulation.
Conclusion
2
Solanum nigrum
L.'s
active component solasodine can target ABCB1 to effectively overcome docetaxel resistance in prostate cancer.
