Heme, an iron–protoporphyrin IX complex, is synthesised through an eight-step pathway beginning and ending in the mitochondrial matrix, with several cytosolic intermediates. Ferrochelatase catalyses ...

The biosynthesis of haem is a multi-step enzymatic process that converts simple precursors into the iron-containing tetrapyrrole cofactor essential for oxygen transport, electron transfer and diverse ...

The process of heme breakdown by heme oxygenase (HMOX) yields bilirubin (BR) and biliverdin (BV) as by-products. Yellow players (YP) are enzymes involved in the production of BR and BV. YP, along with ...

Higher intake of heme iron, the type found in red meat and other animal products—as opposed to non-heme iron, found mostly in plant-based foods—was associated with a higher risk of developing type 2 ...

Heme binding to a bacterial transcription factor is critical for hydrogen sulfide (H₂S) signaling, report researchers from Japan. Heme binding promotes the reaction of H₂S with the transcription ...

In a recent study published in Nature Metabolism, researchers combine traditional clinical indicators with cutting-edge metabolomics data to investigate the processes underlying dietary heme iron ...

Moments of connection between clinicians and patients in oncology: A mixed-methods exploratory study of sacred moments.

AIP is a rare genetic disorder affecting heme production, leading to a buildup of porphyrin precursors that can trigger acute episodes. AIP symptoms can range from abdominal pain and nausea to nerve ...

This study probes the role of Heme Oxygenase-1 (HO-1) and its nuclear interactors in prostate cancer (PCa). Previous results, demonstrated the anti-tumoral role of HO-1 in PCa and its nuclear ...
