Abstract:

Objective To investigate the effect of Kaixinsan (KXS, a traditional Chinese medicine formula) for alleviating adriamycin-induced depression-like behaviors in mice bearing breast cancer xenografts and explore the pharmacological mechanism. Methods Forty female BALB/c mice were randomized equally into control group, model group, and low- and high-dose KXS treatment groups, and in the latter 3 groups, mouse models bearing orthotopic breast cancer 4T1 cell xenografts were established and treated with adriamycin along with saline or KXS via gavage. Depression-like behaviors of the mice were assessed using open field test and elevated plus-maze test, and the changes in serum levels of depression-related factors were examined. RNA-seq analysis and transmission electron microscopy were used and ferroptosis-related factors were detected to explore the mechanisms of adriamycin-induced depression and the therapeutic mechanism of KXS. The results were verified in SH-SY5Y cells using ferroptosis inhibitor Fer-1 as the positive control. Results KXS significantly alleviated depression-like behaviors and depression-related serological changes induced by adriamycin in the mouse models. RNA-seq results suggested that KXS alleviated chemotherapy-induced depression by regulating oxidative stress, lipid metabolism and iron ion binding in the prefrontal cortex. Pathological analysis and detection of ferroptosis-related factors showed that KXS significantly reduced ferroptosis in the prefrontal cortex of adriamycin-treated mice. In SH-SY5Y cells, both KXS-medicated serum and the ferroptosis inhibitor were capable of attenuating adriamycin-induced cell ferroptosis. Conclusion KXS alleviates adriamycin-induced depression-like behaviors in mice by reducing ferroptosis in the prefrontal cortex of breast cancer-bearing mice.
