Abstract: Background Depression promotes breast cancer progression. Given the lack of specific targets for depression-associated breast cancer, there are currently no therapeutic drugs for this type of breast cancer.
Methods Transcriptomic analysis was conducted to identify and functionally annotate genes with differential expression in breast cancer patients exhibiting depressive symptoms. Subsequently, Mendelian randomization was employed to investigate the causal associations between these pivotal genes and breast cancer, thereby validating their potential roles as therapeutic targets. Furthermore, molecular docking techniques were utilized to screen for candidate compounds that may exert therapeutic effects on depression-associated breast cancer. The efficacy of the selected compounds was further assessed using both in vitro cellular experiments and in vivo animal models.
Results We identified IL-8 as a key gene involved in depression-mediated breast cancer progression using transcriptomics. Mendelian randomized analysis suggested that high IL-8 expression promoted breast cancer progression. Further studies demonstrated that IL-8 mediated the breast cancer-promoting effect of depression through the receptor CXCR2. Evidence from both in vitro and in vivo experiments indicates that senkyunolide H may exert its therapeutic effect by regulating CXCR2, thereby counteracting the protumor effects associated with depression in breast cancer.
Conclusion Depression activates CXCR2-mediated breast cancer cell proliferation through IL-8, and senkyunolide H regulates CXCR2 and inhibits its ability to block the cancer-promoting effects of depression, ultimately inhibiting the growth of breast cancer in the context of depression.
