Auranofin Suppresses the Growth of Canine Mammary Tumour Cells and Induces Apoptosis via the PI3K/AKT Pathway.
Canine mammary gland tumour (CMT) is the most common spontaneous tumour in intact female dogs and often exhibits metastases. Auranofin (AF) is a gold complex used for treating rheumatism. The excellent anti-tumour ability of AF has been demonstrated in various types of human and canine tumours. In this study, five CMT cell lines (CIPp, CMT-7364, CHMp, CIPm and CTBp) and three CMT primary cells (G7894, L1883 and L6783) were used to explore the anti-tumour effect of AF on CMT. Two CMT cell lines (CIPp and CMT-7364) were used to search the underlying mechanism of the effect of AF on CMT. The results showed that AF inhibited the growth, migration, invasion, and colony formation abilities of CMT cells. Additionally, the growth of CMT in a 3D cell culture model was effectively suppressed by AF. Furthermore, AF induced cell apoptosis of CMT cells via the PI3K/AKT pathway. In conclusion, AF effectively induces CMT apoptosis by regulating the PI3K/AKT pathway, indicating that AF should be explored as a potential CMT treatment in future studies.
期刊介绍：
Veterinary and Comparative Oncology (VCO) is an international, peer-reviewed journal integrating clinical and scientific information from a variety of related disciplines and from worldwide sources for all veterinary oncologists and cancer researchers concerned with aetiology, diagnosis and clinical course of cancer in domestic animals and its prevention. With the ultimate aim of diminishing suffering from cancer, the journal supports the transfer of knowledge in all aspects of veterinary oncology, from the application of new laboratory technology to cancer prevention, early detection, diagnosis and therapy. In addition to original articles, the journal publishes solicited editorials, review articles, commentary, correspondence and abstracts from the published literature. Accordingly, studies describing laboratory work performed exclusively in purpose-bred domestic animals (e.g. dogs, cats, horses) will not be considered.
