Synthesis pass · prose summary of the discoveries below

Ceruloplasmin (CP) is a multicopper ferroxidase that oxidizes Fe²⁺ to Fe³⁺ to regulate iron efflux from cells, and also functions as a plasma NO oxidase converting NO to nitrite, thereby maintaining both systemic iron and nitric oxide homeostasis (PMID:12055353, PMID:16906150). Loss-of-function mutations cause aceruloplasminemia, an autosomal recessive disorder of iron accumulation in brain, liver, and retina, with CP expression in CNS localized to perivascular astrocytes via a GPI-anchored splice isoform (PMID:7708681, PMID:8968753, PMID:10660599). CP transcription is induced by HIF-1α in response to hypoxia, iron depletion, and copper accumulation, and CP in turn modulates HIF-1α stability, forming a positive feedback loop that suppresses ferroptosis by limiting intracellular Fe²⁺ and lipid ROS accumulation (PMID:15741220, PMID:35101526, PMID:32283255). CP mRNA translation is post-transcriptionally silenced by the IFN-γ-activated GAIT complex, in which phosphorylated GluProRS binds the CP 3′-UTR GAIT element to repress translation via mRNA circularization (PMID:15479637, PMID:12575997).

1984 Human ceruloplasmin is a single polypeptide chain of 1,046 amino acid residues (Mr ~120 kDa) with four N-linked glucosamine oligosaccharide attachment sites; the apparent subunit-like fragments (67-, 50-, and 19-kDa) arise from proteolytic cleavage during purification rather than reflecting a multi-chain structure. Protein sequencing of proteolytic fragments with overlap determination; SDS-PAGE Proceedings of the National Academy of Sciences of the United States of America High 6582496
1995 Loss-of-function mutations in the ceruloplasmin (CP) gene cause aceruloplasminemia, an autosomal recessive disorder characterized by iron accumulation in the brain (basal ganglia), liver, and retina, establishing ceruloplasmin as essential for normal iron efflux from cells with mobilizable iron stores. A 5-bp insertion in exon 7 causing a frameshift and truncated protein was identified as the causative mutation.

1996 Ceruloplasmin gene expression is localized specifically to glial cells (astrocytes) associated with the brain microvasculature, glial cells surrounding dopaminergic neurons in the substantia nigra, and cells in the inner nuclear layer of the retina — tissues that correspond to sites of neurodegeneration in aceruloplasminemia — indicating that glial ceruloplasmin is essential for iron homeostasis and neuronal survival in the CNS.

1998 Ceruloplasmin (Cp) facilitates cellular iron uptake by HepG2 hepatocytes, increasing the apparent affinity for iron substrate approximately 3-fold; Cp synthesis is transcriptionally upregulated 4–5-fold by iron depletion, establishing a transcriptional feedback loop for intracellular iron homeostasis distinct from the post-transcriptional regulation of other iron-handling proteins.

2000 A GPI-anchored isoform of ceruloplasmin is expressed on the surface of brain astrocytes, generated by alternative RNA splicing downstream of exon 18, which replaces the C-terminal 5 amino acids of the secreted hepatocyte form with 30 amino acids that signal GPI anchor addition. The GPI-anchored form is the predominant ceruloplasmin isoform in brain, whereas the secreted form predominates in liver. cDNA cloning; RNase protection analysis comparing brain and liver; sequence analysis of alternatively spliced exon The Journal of biological chemistry High 10660599
2002 Ceruloplasmin functions as a serum ferroxidase that contains >95% of plasma copper and couples substrate (Fe2+) oxidation to the four-electron reduction of O2 to water, acting as a member of the multicopper oxidase family; its primary physiological role is determining the rate of iron efflux from cells with mobilizable iron stores (not copper transport).

2004 Interferon-gamma (IFN-γ) triggers phosphorylation of glutamyl-prolyl-tRNA synthetase (GluProRS), releasing it from the multisynthetase complex; phosphorylated GluProRS then assembles with three additional proteins into the GAIT (IFN-γ-activated inhibitor of translation) complex, which binds the ceruloplasmin (Cp) 3'-UTR GAIT element and silences Cp mRNA translation. GluProRS was identified as a GAIT complex component by RNA affinity chromatography using the Cp GAIT element as ligand.

2005 Copper stabilizes HIF-1α under normoxic conditions by inhibiting prolyl-4-hydroxylase (PHD) activity, leading to HIF-1-dependent transcriptional induction of the ceruloplasmin (CP) gene. Hypoxia also induces hepatic ceruloplasmin in vivo in mice. Both copper and hypoxia drive CP promoter activity via hypoxia-response elements (HREs) in hepatoma cells, revealing that CP is a direct HIF-1 target gene regulated by oxygen, iron, and copper status.

2006 Ceruloplasmin functions as a NO oxidase and nitrite synthase in plasma: it oxidizes nitric oxide (NO) to NO+, which is hydrated to nitrite, thereby maintaining endocrine NO homeostasis. Plasma NO oxidase activity was decreased after ceruloplasmin immunodepletion, in ceruloplasmin knockout (Cp−/−) mice, and in people with congenital aceruloplasminemia. Cp−/− mice had substantially reduced plasma nitrite and were more susceptible to hepatic ischemia-reperfusion injury, which was rescued by nitrite repletion.

2020 Ceruloplasmin (CP) suppresses ferroptosis in hepatocellular carcinoma (HCC) cells by regulating iron homeostasis: CP depletion promotes erastin- and RSL3-induced ferroptotic cell death with accumulation of intracellular Fe2+ and lipid ROS, while CP overexpression suppresses ferroptosis. A novel frameshift mutation in CP (c.1192-1196del) found in patients with iron accumulation and neurodegeneration abolishes CP's ability to regulate iron homeostasis and ferroptosis protection. siRNA knockdown and overexpression of CP in HCC cells; ferroptosis inducers (erastin, RSL3); Fe2+ and lipid ROS measurement; patient-derived CP frameshift mutation functional characterization Cellular signalling High 32283255
2022 The m6A reader Igf2bp1 is upregulated in LPS-activated microglia and enhances m6A methylation and stability of Cp (ceruloplasmin) mRNA (and Gbp11 mRNA), thereby mediating LPS-induced microglial inflammatory activation.

2022 In hepatocellular carcinoma, ionizing radiation reduces COMMD10 expression, causing intracellular copper accumulation, which stabilizes HIF1α (by impairing its ubiquitin-mediated degradation) and promotes HIF1α nuclear translocation. HIF1α then transcriptionally upregulates ceruloplasmin (CP) and SLC7A11, which jointly suppress ferroptosis and confer radioresistance. Elevated CP in turn reduces intracellular Fe2+ levels and further stabilizes HIF1α, forming a positive HIF1α/CP feedback loop.

2024 In cerebral ischemia/reperfusion injury (CIRI), HIF-1α nuclear translocation transcriptionally upregulates CP expression; elevated CP then reduces intracellular iron-dependent ferroptosis but also increases cytoplasmic HIF-1α expression while inhibiting its nuclear translocation, forming an HIF-1α/CP regulatory loop. Chrysin inhibits HIF-1α nuclear translocation, thereby suppressing CP transcription and downstream ferroptosis in CIRI. Overexpression of CP increased HIF-1α expression yet inhibited its nuclear translocation, while CP silencing promoted HIF-1α nuclear accumulation and worsened CIRI. tMCAO rat model; OGD/R in PC12 cells; transcriptomics; qRT-PCR; Western blot; HIF-1α nuclear/cytoplasmic fractionation; CP overexpression and siRNA silencing; ferroptosis marker assays Biomedicine & pharmacotherapy Medium 38555815
2024 In endometrial cancer, lncRNA LINC02936 interacts with the transcription factor SIX1 and recruits it to the CP (ceruloplasmin) promoter, upregulating CP expression, which suppresses ferroptosis and promotes cancer progression.
