表型提示
MGI:88053Mice homozygous for a knock-out allele exhibit normal serum lipid levels on a chow diet, develop hypercholesterolemia only when fed a high-fat/high-cholesterol diet, and show significant increases in the liver content of cholesteryl esters and triglycerides and in biliary cholesterol concentration.
APOC1,即Apolipoprotein C1,是一种在哺乳动物中广泛表达的载脂蛋白,属于载脂蛋白C家族。APOC1主要在肝脏中合成,并在血浆中以极低密度脂蛋白(VLDL)和新生乳糜微粒的形式分泌。APOC1与脂质代谢密切相关,其在脂蛋白上的结合能够影响脂质的转运和代谢过程。APOC1还能够与脂蛋白受体相互作用,影响脂蛋白的降解。此外,APOC1还参与免疫调节和炎症反应,与多种疾病的发生发展密切相关。

近年来,越来越多的研究表明,APOC1在肿瘤发生发展中具有重要作用。例如,在肝细胞癌(HCC)中,APOC1的表达水平与肿瘤微环境中的免疫细胞浸润和肿瘤免疫治疗的效果密切相关。抑制APOC1的表达可以促进肿瘤相关巨噬细胞(TAMs)从M2型转变为M1型,通过铁死亡途径重塑肿瘤免疫微环境,提高抗PD-1免疫治疗的效果[1]。在卵巢癌中,APOC1的表达水平与患者预后相关,APOC1高表达的患者预后较差。此外,APOC1还能够促进卵巢癌细胞增殖、迁移和侵袭,与M2型TAMs的浸润密切相关[2]。在肾细胞癌(RCC)中,APOC1的表达水平与肿瘤免疫细胞浸润和肿瘤转移密切相关。APOC1通过调节巨噬细胞极化,促进M2型巨噬细胞的生成,进而促进肿瘤转移[3]。在IgA肾病中,APOC1的表达水平与肾纤维化程度相关,APOC1通过激活NF-κB信号通路,加剧肾纤维化[4]。在胶质母细胞瘤(GBM)中,APOC1的表达水平与肿瘤发生发展和患者预后相关。APOC1通过降低KEAP1/NRF2和CBS调控的铁死亡,促进GBM肿瘤发生发展[5]。在食管鳞状细胞癌(ESCC)中,APOC1的表达水平与淋巴结转移相关。APOC1阳性的巨噬细胞在转移性肿瘤微环境中表达上调,并与肿瘤和基质细胞的相互作用密切相关[6]。在非小细胞肺癌(NSCLC)中,APOC1的表达水平与患者预后和抗PD-1免疫治疗的效果相关。APOC1通过NRF2/HO-1信号通路,降低M2型巨噬细胞的极化,进而降低抗PD-1免疫治疗的效果[7]。在银屑病和特应性皮炎中,APOC1的表达水平与皮脂腺的脂质代谢和炎症反应相关。APOC1在皮脂腺中表达上调,参与调节脂质代谢和炎症反应[8]。在痴呆症中,APOC1的基因变异与转录调控网络相关。APOC1的功能性基因变异可能影响神经元的转录调控网络,进而影响痴呆症的发生发展[9]。在结直肠癌(CRC)中,APOC1的表达水平与肿瘤微环境和肿瘤进展相关。APOC1在CRC肿瘤相关巨噬细胞中表达上调,抑制APOC1的表达可以降低CRC肿瘤细胞的增殖和迁移[10]。

综上所述,APOC1在多种肿瘤的发生发展和免疫治疗中具有重要作用。APOC1可以通过调节巨噬细胞极化、铁死亡和免疫检查点等途径,影响肿瘤微环境和肿瘤免疫治疗的效果。此外,APOC1还参与脂质代谢、炎症反应和转录调控等生物学过程,与多种疾病的发生发展密切相关。因此,APOC1可能成为肿瘤免疫治疗和多种疾病治疗的新靶点。
