Radhakrishnan Phytotherapy Research ABSTRACT Breast cancer remains a significant global health challenge, with high incidence and mortality rates despite advancements in early detection and treatment. Multidrug resistance (MDR), particularly in aggressive subtypes like triple‐negative breast cancer (TNBC), continues to hinder effective therapy. MDR is primarily driven by the overexpression of ATP‐binding cassette (ABC) transporters such as P‐gp, BCRP, and MRP1. ABC transporters actively efflux chemotherapeutic agents, reducing their efficacy and complicating treatment outcomes. This narrative review explores the potential of natural products to modulate ABC transporters as a strategy to mitigate MDR in breast cancer. A literature search was conducted across Ovid Medline, PubMed, Scopus, Embase, Web of Science, and EBSCOhost. Articles underwent a two‐stage screening process (title and abstract and full text), with additional manual searches of reference lists. The results show that natural products derived from plants can inhibit ABC transporters through suppression of protein expression, downregulation of mRNA expression, and inhibition of drug efflux functions. Additionally, they target indirect regulatory pathways, such as NF‐κB, YB‐1, PI3K/Akt, and ATPase activity, further contributing to the reversal of MDR. These compounds work synergistically with chemotherapeutic agents like doxorubicin and paclitaxel to enhance drug retention and efficacy while reducing toxicity. This multifaceted approach highlights the potential of natural products as valuable adjunct therapies in breast cancer treatment, offering new strategies to overcome drug resistance and improve patient outcomes. 10.1002/ptr.70355 http://creativecommons.org/licenses/by/4.0/ |
