Depression is a common and recurrent mental illness with a complicated etiology, but the specific pathogenesis is not clear. Breast cancer increases susceptibility to depression, which leads to a poor prognosis. Rapid advances in the understanding of tumor immunology and neuroimmunology have provided new evidence for the pathogenesis of depression. Dysfunction of immune cells and cytokines cause depression by affecting tryptophan metabolism, serotonin levels, and blood-brain barrier permeability. Dysregulation of cytokines or intestinal flora may be shared between patients with depression and breast cancer. This review presents an overview of immune dysregulation in breast cancer patients with depression and proposes future alternative research directions and interventions.

Introduction: Triple-negative breast cancer (TNBC) is the most challenging subtype of breast cancer to treat. While previous studies have demonstrated that ginsenoside Rh2 induces apoptosis in TNBC cells, the specific molecular targets and underlying mechanisms remain poorly understood. This study aims to uncover the molecular mechanisms through which ginsenoside Rh2 regulates apoptosis and proliferation in TNBC, offering new insights into its therapeutic potential.

Collagen type XI alpha 1 (COL11A1), a critical member of the collagen superfamily, is essential for tissue structure and integrity. This study aimed to validate previously identified variations in COL11A1 expression during breast cancer carcinogenesis and progression, as well as elucidate their clinical implications. COL11A1 mRNA expression levels were assessed using real-time reverse transcription-PCR (RT-PCR) in 30 pairs of normal breast tissue and primary breast cancer, 30 pairs of primary breast cancer and lymph node metastases, 30 benign tumors, and 107 primary breast cancers.

Increasing evidence has shown that physical exercise remarkably inhibits oncogenesis and progression of numerous cancers and exercise-responsive microRNAs (miRNAs) exert a marked role in exercise-mediated tumor suppression. In this research, expression and prognostic values of exercise-responsive miRNAs were examined in breast cancer (BRCA) and further pan-cancer types. In addition, multiple independent public and in-house cohorts, in vitro assays involving multiple, macrophages, fibroblasts, and tumor cells, and in vivo models were utilized to uncover the tumor-suppressive roles of miR-29a-3p in cancers.
