Abstract
Breast cancer remains a major health concern among women, characterized by a high risk and substantial mortality. Chemotherapy is widely employed as a standard treatment modality to eliminate malignant cells and improve patient survival. Nevertheless, recurrence and chemoresistance arising from taxane treatment have emerged as key factors driving the high mortality rates in cancer patients. Non-coding RNAs (ncRNAs), encompassing microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), represent a key functional output of the human genome and, via intricate regulatory networks, influence nearly all facets of cancer biology, including the development of chemoresistance. Importantly, in taxane-resistant breast cancer cells, the identified miRNAs displayed bifunctional roles: some promoted resistance, whereas others enhanced sensitivity. This functional duality is also observed in lncRNAs, highlighting their context‑dependent regulatory roles. Additionally, ncRNAs are enriched in taxane-resistant cells-derived exosomes, where they play a crucial role in spreading taxane resistance and chemotherapy failure through genetic modulation of taxane‑sensitive cells. Notably, targeting ncRNAs via various therapeutic approaches, including herbal compounds and synthetic peptides, has shown hopeful findings in reversing taxane resistance in breast cancer, highlighting a promising avenue for the management of taxane resistance in breast cancer.
