Abstract:
Cancer is one of the most common causes of death in the world. Despite the fact that there are many types of therapies available, cancer treatment remains a major challenge. The main reason for the ineffectiveness of chemotherapy is the acquisition of multidrug resistance (MDR) by cancer cells. One of the factors responsible for the acquisition of MDR is the NRF2 transcription factor, which regulates the expression of proteins such as HO-1, NQO1, MRP1, MRP2, and GST. In normal cells, NRF2 is the first line of defense against oxidative stress, thereby preventing carcinogenesis. Still, its hyperactivation in cancer cells causes them to acquire MDR, which significantly reduces or eliminates the effectiveness of chemotherapy. Considering the important role NRF2 plays in the acquisition of MDR, its modulators and, above all, inhibitors are being sought after, including among compounds of plant origin. NRF2 inhibition may prove to be a key element of anticancer therapy. This review summarizes the current state of knowledge about plant NRF2 inhibitors and presents the effects of their use in overcoming MDR in cancer.
Insights
Plant-derived compounds that inhibit the NRF2 pathway can help overcome multidrug resistance (MDR) in cancer. This approach targets a key factor in chemotherapy ineffectiveness, offering new therapeutic strategies.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Cancer remains a leading cause of death globally, with chemotherapy often failing due to multidrug resistance (MDR).
- The transcription factor NRF2 (Nuclear factor erythroid 2-related factor 2) plays a dual role: protecting normal cells from oxidative stress but promoting MDR in cancer cells.
- Hyperactivation of NRF2 in cancer cells leads to the upregulation of genes (e.g., HO-1, NQO1, MRP1, MRP2, GST) that confer resistance to chemotherapy.
Purpose of the Study:
- To review the current knowledge on plant-derived NRF2 inhibitors.
- To explore the potential of NRF2 inhibition as a strategy to overcome MDR in cancer treatment.
Main Methods:
- Literature review of studies investigating plant compounds targeting the NRF2 pathway.
- Analysis of research on the role of NRF2 in MDR and the efficacy of its inhibitors.
Main Results:
- NRF2 is a critical factor in the development of MDR, significantly limiting chemotherapy effectiveness.
- Numerous plant compounds have been identified as NRF2 modulators, with many acting as inhibitors.
- Inhibition of NRF2 by plant-derived compounds shows promise in reversing MDR and enhancing chemotherapy efficacy.
Conclusions:
- NRF2 inhibition is a promising strategy for overcoming chemotherapy resistance in cancer.
- Plant-derived NRF2 inhibitors represent a valuable resource for developing novel anticancer therapies.
- Targeting NRF2 could be a key component in future cancer treatment regimens to improve patient outcomes.
