n-3 PUFAs Show Promise as Adjuvants in Chemotherapy, Enhancing their Efficacy while Safeguarding Hematopoiesis and Promoting Bone Generation

Curr Top Med Chem. 2023 Oct 27. doi: 10.2174/0115680266258838231020102401. Online ahead of print.ABSTRACTCancer ranks as the second leading cause of mortality in high-income countries, underscoring the critical need for effective therapeutic strategies. One prominent approach, chemotherapy, is widely employed for treating solid tumors. However, the significant adverse effects associated with chemotherapy, notably myeloablation and osteonecrosis, impart considerable challenges by compromising immune function and diminishing patients' quality of life. Furthermore, the emergence of chemotherapy resistance poses a formidable hurdle in achieving successful cancer treatment outcomes. In this context, the focus is on exploring alternative approaches to enhance the efficacy of cancer treatment and mitigate its adverse consequences. Among these approaches, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), two n-3 polyunsaturated fatty acids (PUFAs), have garnered substantial interest. These PUFAs exhibit the potential to influence membrane lipid composition and modulate critical gene expressions associated with cancer, such as Bcl-2, PI3K, NF-κB, and phosphorylated Akt, thereby potentially reducing cancer risk. Moreover, emerging evidence highlights their ability to augment chemotherapy efficacy, particularly in drug-resistant cancer cells. Importantly, both preclinical and clinical investigations have provided compelling evidence supporting the protective effects of n-3 PU...
