Contribution of PGE2 EP1 receptor in hemin-induced neurotoxicity

Frontiers in Molecular Neuroscience, 2013
Although hemin-mediated neurotoxicity has been linked to the production of free radicals and glutamate excitotoxicity, the role of the prostaglandin E2 (PGE2)-EP1 receptor remains unclear.

Esterification of hemins with trimethyloxonium tetrafluoroborate [PDF]

Analytical Biochemistry, 1976
A procedure has been developed for the methylation of hemins using trimethyloxonium tetrafluoroborate. The method is rapid and selective for carboxyl groups, and it can be used to methylate polar and nonpolar hemins under neutral and basic conditions. Esterifications of protohemin IX, hematohemin.

Interaction of hemin with quadruplex DNA [PDF]

Journal of Biological Physics, 2016
A DNA enzyme with peroxidase activity is a G-quadruplex-based DNAzyme formed by hemin and G-quadruplex DNA. Activity of peroxide DNAzymes can be influenced by the structure of quadruplex DNA. In this investigation, the interaction of hemin with T30695 G-quadruplex DNA is evaluated.

Induction of Heme Oxygenase-1 Modifies the Systemic Immunity and Reduces Atherosclerotic Lesion Development in ApoE Deficient Mice

Frontiers in Pharmacology, 2022
Heme oxygenase-1 (HO-1) has been reported to protect against oxidation and inflammation in atherosclerosis. It remains unclear how the immune system participates in the cytoprotective function of HO-1 in the context of atherosclerosis.
