TNBC, the most malignant subtype of breast cancer, is characterized by high rates of cell proliferation and poor prognosis. Chemotherapy is the primary therapeutic strategy, but targeted therapies for TNBC are lacking. CircRNAs show potential as biomarkers for TNBC diagnosis, prognosis, and treatment, but further research is needed to understand their functions.
Triple-negative breast cancer (TNBC), which is the most malignant subtype of breast cancer (BC), accounts for 10%-20% of all BC cases. TNBC, which occurs more frequently in young women, is characterized by high rates of cell proliferation and metastasis and poor prognosis. Chemotherapy is the primary systemic therapeutic strategy for TNBC. However, chemotherapy is largely unsuccessful, and effective targeted therapies for TNBC have not been established. Therefore, it isa matter of great urgency to identify precise molecular targets for the promising prognosis of patients with TNBC. Circular RNAs (circRNAs), which are a type of non-coding RNAs (ncRNAs), are abundantly expressed in the eukaryotic cells and exhibit diverse cellular functions. The roles of circRNAs are to sponge microRNA or RNA-binding proteins, regulate gene expression, and serve as templates for translation. Here, we review the current findings on the potential of circRNAs as a diagnostic, prognostic, and therapeutic biomarker for TNBC. However, further studies are essential to elucidate the functions of circRNAs in TNBC. This review also discusses the current limitations and future directions of TNBC-associated circRNAs, which can facilitate the translation of experimental research into clinical application.
