The anti-melanoma roles and mechanisms of tricholoma isoflavone derivative CA028.

Abstract

As a form of skin cancer, melanoma's incidence rate is continuing to rise globally. Therefore, there is an urgent need to find new agents to improve survival in melanoma patients. Isoflavones, a class of phytoestrogens, are primarily found in soy and other legumes. Cumulating evidence demonstrates that isoflavones exhibits significant anti-tumor properties and is beneficial for the prevention and treatment of melanoma. In the present study, we aim to investigate the anti-melanoma role of tricholoma isoflavone derivative CA028. By using in vitro melanoma cell line models, A375 and A2058 and in vivo xenograft mouse model, our results indicate that melanoma proliferation, migration, and invasion are attenuated following CA028 treatment. In addition, the treatment of CA028 induced cell apoptosis of melanoma. Finally, we addressed the mechanism of CA028 against melanoma by comparative transcriptomic analysis. The results of gene ontology highlighted the involvement of CA028's targets in the cell proliferation, cell apoptosis, and migration ability of melanoma cells. Furthermore, Ingenuity Pathway Analysis constructed the network involved in the apoptotic roles of CA028 through targeting p53 signaling and death receptor signaling. For the first time, our data suggested the possible use of modified isoflavone for therapeutic applications against melanoma.
