BackgroundPlatinum-based chemotherapy is one of the main treatments for lung adenocarcinoma (LUAD). However, the toxic side effects and drug resistance of chemotherapeutic drugs on normal cells are still a thorny problem in clinical treatment. Dendrobium is one of the three largest genera of Orchidaceous family, which has ornamental and medicinal value. Dendrobium is mainly distributed in the tropics and subtropics of South Asia, Oceania and other regions, with 1547 species of Dendrobium currently known. In China, “Shi hu” and “Tie pi shi hu” are well-known traditional medicines and have been included in the Chinese Pharmacopoeia (Editorial Board of Chinese Pharmacopoeia, 2020). Erianin is a natural product isolated from Dendrobium and is considered as a potential anticancer molecule due to its remarkable anti-tumor effects through various mechanisms, among which induced cancer cell apoptosis, inhibited invasion and migration. This study preliminarily explored the mechanism of Erianin inhibiting the progression of cisplatin (DDP) resistant LUAD in vivo and in vitro.MethodsThe effect of Erianin on the proliferation of DDP-resistant LUAD cells was detected by CCK-8 assay, wound healing assay and cloning assay. Transwell assay was used to evaluate the effect of Erianin on cell invasion and migration. The changes of cell cycle and apoptosis were detected by flow cytometry and TUNEL assay. Finally, the effects of Erianin on cell function and signaling pathway-related protein expression in vivo and in vitro were examined based on the enrichment analysis.ResultsErianin could inhibit the proliferation, invasion and migration, induce apoptosis, altered cell cycle of DDP-resistant LUAD cells, and reverse the resistance to DDP. Western blotting results showed that Erianin exerted its anti-tumor effects by regulating the Wnt/β-catenin cascade in DDP-resistant LUAD cells.ConclusionErianin may exerted its anti-tumor effect in DDP-resistant LUAD cells by regulating the Wnt3/β-Catenin/Survivin/Bcl-2/Caspase-3/Cyclin D1 axis.
