The hemopexin and O-glycosylated domains tune gelatinase B/MMP-9 bioavailability via inhibition and binding to cargo receptors

open access: yes, 2006
Gelatinase B/matrix metalloproteinase-9 (MMP-9), a key regulator and effector of immunity, contains a C-terminal hemopexin domain preceded by a unique linker sequence of ∼64 amino acid residues. This linker sequence is demonstrated to be an extensively O-

What Is Next in This “Age” of Heme-Driven Pathology and Protection by Hemopexin? An Update and Links with Iron

open access: yesPharmaceuticals, 2019
This review provides a synopsis of the published literature over the past two years on the heme-binding protein hemopexin (HPX), with some background information on the biochemistry of the HPX system.

Free heme exacerbates colonic injury induced by anti-cancer therapy

open access: yesFrontiers in Immunology, 2023
Gastrointestinal inflammation and bleeding are commonly induced by cancer radiotherapy and chemotherapy but mechanisms are unclear. We demonstrated an increased number of infiltrating heme oxygenase-1 positive (HO-1+) macrophages (Mø, CD68+) and the ...

Interactions of Porphyrins with Rabbit Hemopexin

open access: yesJournal of Biological Chemistry, 1972
Abstract The formation of complexes of rabbit hemopexin with a representative group of porphyrins was investigated to determine the stoichiometry and estimated dissociation constants (Kd) as well as the effect of pH on these interactions. In a 1:1 molar ratio, rabbit apohemopexin (RHx) binds iron-protoporphyrin IX (heme), iron-deuteroporphyrin IX ...

Prediction of Intact N-Glycopeptide Retention Time Windows in Hydrophilic Interaction Liquid Chromatography

open access: yesMolecules, 2022
Analysis of protein glycosylation is challenging due to micro- and macro-heterogeneity of the attached glycans. Hydrophilic interaction liquid chromatography (HILIC) is a mode of choice for separation of intact glycopeptides, which are inadequately ...

Assessment of Ceruloplasmin, Hemopexin, and Haptoglobin in Asthmatic Children [PDF]

open access: yes, 2020
BACKGROUND: Ceruloplasmin (Cp), haptoglobin, and hemopexin play a role in iron homeostasis and may function to modulate the systemic inflammatory response and be involved in tissue repair.

Strongyloidiasis stercoralis coinfection is associated with altered iron status biomarkers in tuberculous lymphadenitis

open access: yesFrontiers in Immunology, 2022
Soil-transmitted helminth [mainly Strongyloidiasis stercoralis (Ss)] and tuberculous lymphadenitis (TBL) coinfection in humans is a significant public health problem. We have previously shown that TBL+Ss+ coinfection significantly alters diverse cytokine,

Small scale purification and biophysical characterization of haptoglobin derived from human Cohn fraction IV

open access: yesBiotechnology Progress, EarlyView.
Abstract Haptoglobin (Hp) is a polymorphic acute phase α‐2 glycoprotein found in plasma that plays a critical role in binding, neutralizing, and removing cell‐free hemoglobin (Hb) from the circulation. Under clinical conditions characterized by high levels of hemolysis, such as in patients with sickle cell disease (SCD), large quantities of cell‐free ...

Unraveling the Plasma Extracellular Vesicles Proteome: Predictors of Resistance in Immunotherapy of Advanced Melanoma

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Despite substantial clinical benefit from immune checkpoint inhibitors (ICI), advanced melanoma remains challenging due to frequent treatment resistance. Resistance may be intrinsic (primary) or emerge over time (secondary). Biomarkers predicting distinct resistance phenotypes before therapy are lacking.
