MGI:96757 Homozygous mutants are more susceptible to infection with bacteria that utilize enterochelin-type siderophores to acquire iron and impaired thermogenesis. Mice homozygous for another knock-out allele exhibit apoptotic defects in hematopoietic cells.
基因研究概述
Lcn2,也称为Lipocalin 2,是一种重要的分泌性糖蛋白。Lipocalin家族是一组小分子蛋白质,主要参与细胞内铁代谢的调控,Lcn2是其中的一员。Lcn2通过结合并运输游离的铁离子,调节铁的稳态,对细胞的生长、发育和生理功能具有重要影响。Lcn2在多种生物学过程中发挥作用,包括细胞分化、发育、代谢和疾病发生。
Lcn2在多种疾病中发挥重要作用,包括溃疡性结肠炎(UC)、缺氧缺血性脑损伤(HIBD)、糖尿病视网膜病变(DR)、肺腺癌(LUAD)、非酒精性脂肪性肝炎(NASH)、心肌梗死(MI)、脓毒症引起的急性呼吸窘迫综合征(ARDS)和去势抵抗性前列腺癌(CRPC)。在UC中,Lcn2表达升高,与铁死亡相关,抑制Lcn2可以抑制铁死亡事件[1]。在HIBD中,Lcn2表达升高,与铁死亡相关,抑制Lcn2可以抑制铁死亡事件[2]。在DR中,Lcn2表达升高,通过Kdm6a介导的表观遗传沉默,影响光感受器细胞的功能[3]。在LUAD中,Lcn2表达升高,与肿瘤的发生和进展相关,抑制Lcn2可以抑制肿瘤细胞的增殖、迁移和侵袭[4]。在NASH中,Lcn2表达升高,与肝脏纤维化相关,抑制Lcn2可以减轻肝脏纤维化[5]。在MI中,Lcn2表达升高,与心肌损伤和不良重塑相关,抑制Lcn2可以减轻心肌损伤和不良重塑[6]。在ARDS中,Lcn2表达升高,与铁死亡相关,抑制Lcn2可以抑制铁死亡事件[7]。在CRPC中,Lcn2表达升高,与肿瘤的发生和进展相关,抑制Lcn2可以抑制肿瘤细胞的迁移和侵袭[8]。
综上所述,Lcn2是一种重要的分泌性糖蛋白,参与调控细胞内铁代谢,影响细胞的生长、发育和生理功能。Lcn2在多种疾病中发挥重要作用,包括UC、HIBD、DR、LUAD、NASH、MI、ARDS和CRPC。Lcn2的研究有助于深入理解铁代谢的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
