铁死亡是一种新发现的程序性细胞死亡形式,其特征是铁过载及脂质过氧化。越来越多的证据表明,铁死亡与妊娠相关疾病的发生密切相关有关,而抑制铁死亡对于妊娠相关疾病的治疗具有一定作用。本综述总结了铁死亡发生的分子机制及铁死亡在妊娠相关疾病中的最新研究进展,期望对妊娠相关疾病的诊治带来新的思路。Ferroptosis is a newly discovered form of programmed cell death characterized by iron overload and lipid peroxidation. Accumulating evidence suggests a significant association between ferroptosis and the pathogenesis of pregnancy-related disorders. Studies have shown that inhibiting ferroptosis may offer therapeutic benefits in managing these conditions. This review aims to elucidate molecular mechanisms underlying ferroptosis and to summarize recent advancements in understanding its role in pregnancy-related diseases, thereby providing novel insights for the diagnosis and treatment of such disorders.

目的探讨HPV16(Human Papillomavirus Type 16)E6-295T/G和E6-350T/G变异位点对IFNκ、MHC-Ⅰ、STAT1和IRF9蛋白质表达的影响。方法在宫颈癌细胞C33A(HPV阴性)中分别转染真核表达载体295G/350G-GV230、295T/350G-GV230和295T/350T-GV230作为实验组,以NC-GV230作为对照组。通过免疫组织化学法、Western blot方法检测HPV16 E6295T/G、350T/G不同变异位点对IFNκ、MHC-Ⅰ、STAT1和IRF9蛋白质表达的影响。通过IBM SPSS Statistics 26软件对实验结果进行统计学分析,P<0.05为差异具有统计学意义,免疫组织化学法定量采用image J软件进行阳性细胞计数。结果Western blot结果显示,免疫分子干扰素κ(Interferon Kappa,IFNκ)的表达,HPV16 E6-295G/350G变异组较HPV16 E6-295T/350T原型组和HPV16 E6-295T/350G组降低(P<0.01,P<0.05)。HPV16 E6-295G/350G变异组的免疫分子主要组织相容性复合体I类(Major Histocompatibility Complex Class I,MHC-I)的表达显著低于HPV16 E6-295T/350T原型组和HPV16 E6-295T/350G组(P<0.05)。HPV16 E6-295G/350G变异组的信号转导子和转录激活子1(Signal Transducer and Activator of Transcription 1,STAT1)表达显著低于HPV16 E6-295T/350T原型组和HPV16 E6-295T/350G组(P<0.05,P<0.01)。变异组HPV16 E6-295G/350G与HPV16 E6-295T/350T原型组和HPV16 E6-295T/350G变异组相比,干扰素调节因子9(Interferon Regulatory Factor 9,IRF9)表达显著降低(P<0.05,P<0.01)。结论HPV16病毒E6蛋白质可以降低IFNκ、MHC-Ⅰ、STAT1和IRF9的蛋白质表达水平,E6基因T295G/T350G变异降低这些分子的表达作用最强。
