Abstract Title:
Licochalcone A inhibits PI3K/Akt/mTOR signaling pathway activation and promotes autophagy in breast cancer cells.
Abstract:
Previous studies have demonstrated that Licochalcone A possesses anti-inflammatory, anticancer, anti-bacterial, anti-malarial and anti-parasitic activities. In the present study the potential anticancer effects of Licochalcone A on MCF-7 cells were investigated. Licochalcone A significantly decreased cell viability and promoted autophagy and apoptosis, as demonstrated by an MTT assay, acridine orange staining and Annexin V-fluorescein isothiocyanate staining, respectively. Western blot analyses demonstrated that Licochalcone A treatment activated the LC3-II signaling pathway while suppressing the phosphoinositide 3-kinase (PI3K)/RAC-α serine-threonine-protein kinase (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. In addition, Licochalcone A significantly increased caspase-3 activity and significantly decreased B-cell lymphoma-2 expression. The results from the present study indicate that Licochalcone A inhibits PI3K/Akt/mTOR activation, and promotes autophagy and apoptosis in MCF-7 cells.
