Double-edged functions of hemopexin in hematological related diseases: from basic mechanisms to clinical application

open access: yesFrontiers in Immunology, 2023
It is now understood that hemolysis and the subsequent release of heme into circulation play a critical role in driving the progression of various diseases.

Hemopexin Modulates Expression of Complement Regulatory Proteins in Rat Glomeruli

open access: yesCurrent Issues in Molecular Biology, 2021
In systemic hemolysis and in hematuric forms of kidney injury, the major heme scavenging protein, hemopexin (HPX), becomes depleted, and the glomerular microvasculature (glomeruli) is exposed to high concentrations of unbound heme, which, in addition to ...

Insulin attenuates TNFα-induced hemopexin mRNA: An anti-inflammatory action of insulin in rat H4IIE hepatoma cells

open access: yesBiochemistry and Biophysics Reports, 2017
Proinflammatory cytokines, including TNF-α and IL-6, can contribute to insulin resistance. Conversely, insulin has some actions that can be considered anti-inflammatory.

Heme‐hemopexin: A ‘Chronosteric’ heme‐protein [PDF]

open access: yesIUBMB Life, 2007
AbstractHemopexin (HPX) serves as scavenger and transporter of toxic plasma heme to the liver. HPX is formed by two four‐bladed β‐propeller domains, resembling two thick disks that lock together at a 90° angle. The heme is bound between the two β‐propeller domains in a pocket formed by the interdomain linker peptide.

Heme as Possible Contributing Factor in the Evolvement of Shiga-Toxin Escherichia coli Induced Hemolytic-Uremic Syndrome

open access: yesFrontiers in Immunology, 2020
Shiga-toxin (Stx)-producing Escherichia coli hemolytic-uremic syndrome (STEC-HUS) is one of the most common causes of acute kidney injury in children.

Protease activity of plasma hemopexin [PDF]

open access: yesKidney International, 2005
Previous studies into the relevance of a putative circulating factor in the pathogenesis of minimal change nephrotic syndrome have opened the possibility that plasma hemopexin might be an important effector molecule in this disorder. Thus, intra renal infusion of isolated plasma hemopexin into rats induced minimal change like glomerular lesions and ...

Stromal expression of hemopexin is associated with lymph-node metastasis in pancreatic ductal adenocarcinoma.

open access: yesPLoS ONE, 2020
Pancreatic ductal adenocarcinoma is one of the most aggressive types of cancer. Certain proteins in the tumor microenvironment have attracted considerable attention owing to their association with tumor invasion and metastasis.

TLR4 Signaling by Heme and the Role of Heme-Binding Blood Proteins

open access: yesFrontiers in Immunology, 2020
Toll-like receptors (TLRs), also known as pattern recognition receptors, respond to exogenous pathogens and to intrinsic danger signals released from damaged cells and tissues.

A Rapid LC-MS/MS-PRM Assay for Serologic Quantification of Sialylated O-HPX Glycoforms in Patients with Liver Fibrosis

open access: yesMolecules, 2022
Development of high throughput robust methods is a prerequisite for a successful clinical use of LC-MS/MS assays. In earlier studies, we reported that nLC-MS/MS measurement of the O-glycoforms of HPX is an indicator of liver fibrosis.

The Diversity of Mammalian Hemoproteins and Microbial Heme Scavengers Is Shaped by an Arms Race for Iron Piracy

open access: yesFrontiers in Immunology, 2018
Iron is an essential micronutrient for most living species. In mammals, hemoglobin (Hb) stores more than two thirds of the body's iron content. In the bloodstream, haptoglobin (Hp) and hemopexin (Hpx) sequester free Hb or heme.
