| Summary: | Breast cancer is the leading threat to the health of women, with a rising global incidence linked to social and psychological factors. Among its subtypes, triple-negative breast cancer (TNBC), which lacks <i>estrogen receptor (ER)</i>, <i>progesterone receptor (PR)</i>, and <i>human epidermal growth factor receptor 2 (HER2)</i> expression, is highly heterogeneous with early metastasis and a poor prognosis, making it the most challenging subtype. Mounting evidence shows that the mitochondrial quality control (MQC) system is vital for maintaining cellular homeostasis. Dysfunction of the MQC is tied to tumor cell invasiveness, metastasis, and chemoresistance. This paper comprehensively reviews the molecular link between MQC and TNBC development. We focused on how abnormal MQC affects TNBC progression by influencing chemoresistance, immune evasion, metastasis, and cancer stemness. On the basis of current studies, new TNBC treatment strategies targeting key MQC nodes have been proposed. These findings increase the understanding of TNBC pathogenesis and offer a theoretical basis for overcoming treatment challenges, providing new research angles and intervention targets for effective precision therapy for TNBC. |
