Descripción general

Bilirubin, a heme catabolism end-product is produced by the reduction of its metabolic precursor biliverdin by the action of enzyme biliverdin reductase.

Aplicación

Bilirubin has been used as an interfering substance for in vitro interference and stability tests for myoglobin, creatine kinase-MB (CK-MB), and troponin-I. It has also been used as an interfering agent to test the effectiveness of the Heparin Red kit in the detection of various heparins.

Acciones bioquímicas o fisiológicas

Más del 99 % de la bilirrubina total es transportada como un conjugado con la albúmina. Niveles anormalmente elevados de bilirrubina pueden causar un daño neurológico grave, pero niveles levemente elevados están vinculados a la protección frente al estrés oxidativo.
Bilirubin is an active oxidative DNA cleaving agent as well as an effective antioxidant agent, a hydroxyl radical quencher. This bile pigment has both antioxidant and toxic properties. It is a natural inhibitor of vascular smooth muscle cell proliferation (VSMCs). It displays anti-inflammatory and anti-proliferative properties when used as a therapeutic agent in lung/vascular diseases. Serum bilirubin concentration slightly above the normal levels have shown a lesser incidence of heart disease. It is a potential therapeutic agent in heart transplantation and T-cell mediated immune disorders.

Heme oxygenase (HO)-1, an inducible, low-molecular-weight stress protein, confers cellular and tissue protection in multiple models of injury and disease, including oxidative or inflammatory lung injury, ischemia/reperfusion (I/R) injuries, and vascular injury/disease. The tissue protection provided by HO-1 potentially relates

Recent epidemiological and clinical data show protection from CVD (cardiovascular disease), all-cause mortality and cancer in subjects with GS (Gilbert's syndrome), which is characterized by a mildly elevated blood bilirubin concentration. The established antioxidant effect of bilirubin, however, contributes only
