In Vivo Model
Six-week-old athymic BALB/c male nude mice (nu/nu) were purchased from OrientBio (Seoul, Republic of Korea). HN9 cells with transfection of CDH1 or control vector or HN4 cells with ZEB1 or control vector were subcutaneously injected into the bilateral flank of nude mice. From the day when gross nodules were detected in tumor implants, mice were subjected to different treatments: vehicle or sulfasalazine (250 mg/kg daily per intraperitoneal route). Each group included six mice.

Response regulation Histone deacetylase SIRT1 gene silencing or pharmacological inhibition by EX-527 suppressed EMT and consequently decreased ferroptosis, whereas SIRT inducers, resveratrol and SRT1720, increased ferroptosis. In head and neck cancer (HNC) cells with low expression of E-cadherin, the treatment of 5-azacitidine diminished the hypermethylation of CDH1, resulting in increased E-cadherin expression and decreased ferroptosis susceptibility.
