表型提示
MGI:96837Mice homozygous for a knock-out allele are viable, fertile, and grossly normal and exhibit only minor alterations in iron homeostasis. Mice homozygous for a different knock-out allele show increased susceptibility to inflammation-induced colorectal dysplasia along with increased cell proliferation and decreased apoptosis in colonic tissues.
基因Ltf,也称为Lactotransferrin,是一种在哺乳动物中广泛表达的铁结合蛋白。Ltf基因编码的乳铁蛋白(Lactoferrin)是一种具有多种生物学功能的蛋白质,包括调节铁代谢、免疫调节、抗菌和抗病毒活性等。Ltf的表达和功能在多种生理和病理过程中发挥重要作用,例如在免疫系统中,Ltf可以促进免疫细胞的分化,调节免疫反应;在铁代谢中,Ltf可以结合并转运铁,维持铁稳态;在抗菌和抗病毒活性中,Ltf可以通过结合并抑制细菌和病毒的生长和复制来发挥保护作用。

Ltf基因在多种癌症中表达异常,并且与疾病的预后和治疗效果相关。例如,在肝细胞癌(HCC)中,高表达的METTL16可以与IGF2BP2协同作用,调节SENP3 mRNA的稳定性,进而抑制LTF的泛素化降解,从而促进HCC的发生和发展[1]。在胶质母细胞瘤(GBM)中,LTF的表达与患者的生存期呈负相关,并且LTF可能通过诱导免疫浸润失调在GBM中发挥致癌作用[2]。在肺鳞状细胞癌(LUSC)中,LTF的表达与放疗抵抗性相关,并且LTF可以通过促进自噬和形成AMPK/SP2/NEAT1/miR-214-5p反馈回路来诱导放疗抵抗性[3]。此外,Ltf基因在糖尿病脑出血、前列腺癌、骨肉瘤和半月板退变等疾病中也发挥重要作用,并且与疾病的预后和治疗效果相关[4,5,6,7,8]。

综上所述,Ltf基因编码的乳铁蛋白在多种生理和病理过程中发挥重要作用,并且与多种疾病的预后和治疗效果相关。Ltf基因的研究有助于深入理解Ltf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。
