ABSTRACT
The objective of this study was to explore the effects and mechanisms of the combination of isobavachalcone (IBC) and doxorubicin (DOX) on the progression of anaplastic thyroid cancer (ATC). Cell viability of 8505C and CAL62 cells was observed by CCK-8 assay. Kits were used to detect the presence of reactive oxygen species (ROS), glutathione (GSH), malondialdehyde (MDA), and cellular iron. Protein expression of solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) was detected using western blot, and CD31 was detected through immunofluorescence. Tumor xenograft models of 8505C cells were constructed to observe the effect of IBC and DOX on ATC growth in vivo. The co-administration of IBC and DOX exhibited a synergistic effect of suppressing the growth of 8505C and CAL62 cells. The concurrent use of IBC and DOX resulted in elevated iron, ROS, and MDA levels, while reducing GSH levels and protein expression of SLC7A11 and GPX4. However, the Fer-1 ferroptosis inhibitor effectively counteracted this effect. In vitro and in vivo, the inhibitory effect on ATC cell proliferation and tumor growth was significantly enhanced by the combination of IBC and DOX. The combination of IBC and DOX can inhibit the growth of ATC by activating ferroptosis, and might prove to be a potent chemotherapy protocol for addressing ATC.
