PG - 102187 LID - S0040-8166(23)00175-1 [pii] LID - 10.1016/j.tice.2023.102187 [doi] AB - Laryngeal squamous cell carcinoma (LSCC) is the second most common head and neck cancer. To identify the link between ferroptosis and LSCC, we targeted the dual oxidase 1 (DUOX1) gene. This study aimed to reveal the intrinsic mechanism by which the DUOX1-zinc-finger CCCH domain-containing protein 13 (ZC3H13) ferroptosis axis affected the LSCC process. GEPIA was used to investigate the expression of DUOX1 in LSCC, and the expression levels of DUOX1 and ZC3H13 were manipulated by overexpression and RNA interference. MTT assay was used to detect cell proliferation. Chromatin immunoprecipitation (CHIP) detected the binding of DUOX1 and ZC3H13, and ROS assessment and intracellular Fe(2+) content determination were performed to examine the ferroptosis. MeRIP was used to analyze the m6A methylation of DUOX1. Ferroptosis-related proteins were detected by qRT-PCR. DUOX1 was found to be poorly expressed in LSCC cells, low DUOX1 level promoted LSCC cell proliferation, and low ZC3H13 level decreased LSCC cell proliferation. Besides, there was an interaction between DUOX1 and ZC3H13. DUOX1 could inhibit the expression levels of ferroptosis-related genes GPX4 and F1H1 in LSCC cells DUOX1 inhibited the expression levels of ROS and ferroptosis-related genes GPX4 and F1H1 and increased intracellular iron content in LSCC cells, but ZC3H13 reversed this phenomenon by inhibiting DUOX1 gene through m6A methylation modification. ZC3H13 reduced DUOX1-mediated ferroptosis in LSCC cells through m6A-dependent modification. The regulatory pathway of DUOX1 and ferroptosis are potential targets for designing diagnostic and combination therapeutic strategies for LSCC patients. CI - Copyright (c) 2023 Elsevier Ltd.
