An insight into the therapeutic effects of isoliquiritigenin in breast cancer.

Abstract

Breast cancer ranks as the most widespread malignant condition in women, emerging as a primary contributor to mortality. The primary challenges in cancer treatments involve undesirable side effects. Therefore, exploring natural compounds as additional therapy could provide valuable insights. Isoliquiritigenin (ILN), an isoflavonoid featuring a chalcone moiety primarily sourced from Glycyrrhiza species, has garnered increasing interest in breast cancer research. This review aims to provide a comprehensive understanding of ILN's mechanisms of action in breast cancer, drawing from a range of in vitro and in vivo studies. ILN primarily acts by inhibiting angiogenesis, aromatase, inflammation, and cell proliferation, and preventing invasion and metastasis. Mechanistically, it downregulates miR-374a, phosphoinositide-3-kinase-protein kinase B/Akt, maternal embryonic leucine zipper kinase, vascular endothelial growth factor, and estrogen receptor protein levels, and causes enhancement of Wnt inhibitory factor-1, and Unc-51-like kinase 1 expression to treat breast cancer. ILN emerges as a promising natural option, offering therapeutic advantages with minimal side effects. However, it is important to note that current research on ILN is primarily limited to preclinical models, underscoring the need for further investigation to validate its potential efficacy.
