Abstract:
We have recently reported that the central heme oxygenase (HO) pathway has an important role in the genesis of lipopolysaccharide fever. However, the HO product involved, i.e., biliverdine, free iron, or carbon monoxide (CO), has not yet been identified with certainty. Therefore, in the present study, we tested the thermoregulatory effects of all HO products. Body core temperature (Tc) and gross activity of awake, freely moving rats was measured by biotelemetry. Intracerebroventricular administration of heme-lysinate (152 nmol), which induces the HO pathway, evoked a marked increase in Tc, a r

Heme oxygenase catalyzes the metabolism of heme to biliverdine, free iron, and carbon monoxide. The current study was designed to determine if treatment with the heme oxygenase substrates heme-L-arginate or heme-L-lysinate, to stimulate formation of heme oxygenase products, can lower blood pressure in the rat. Heme-L-arginate (45 mumol/kg ip) and heme-L-lysinate (45 mumol/kg ip) acutely lowered blood pressure in awake spontaneously hypertensive rats (SHR) by approximately 35 mmHg. For both heme oxygenase substrates, this effect was blunted by pretreatment with an inhibitor of heme oxygenase, z

Oxidation of bilirubin to biliverdin inside mitochondria must be followed by the export of biliverdin to the cytosol, where biliverdin is reduced back to bilirubin.

Abstract:
The family of haem oxygenase enzymes is unique in nature for its role in haem degradation. Haem is cleaved at the α-meso position by haem oxygenase with the support of electrons donated by cytochrome P450 reductase, the first products of this reaction being CO, iron and biliverdin. Biliverdin is then converted to bilirubin by biliverdin reductase. If haem is viewed as a substrate for an anabolic pathway, it becomes evident that haem oxygenases do not break down haem for elimination from the body, but rather use haem to generate crucial molecules that can modulate cellular functions.

Tubuloglomerular feedback (TGF) is the mechanism by which the macula densa (MD) senses increases in luminal NaCl concentration and sends a signal to constrict the afferent arteriole (Af-Art). The kidney expresses constitutively heme oxygenase-2 (HO-2) and low levels of HO-1. HOs release carbon monoxide (CO), biliverdin, and free iron. We hypothesized that renal HOs inhibit TGF via release of CO and biliverdin. Rabbit Af-Arts and attached MD were simultaneously microperfused in vitro. The TGF response was determined by measuring Af-Art diameter before and after increasing NaCl in the MD perfusa

Abstract:
Biliverdin reductase (BVR) functions in cell signaling through three distinct tracks: a dual-specificity kinase that functions in the insulin receptor/MAPK pathways ( 25 , 29 , 51 ); a bzip-type transcription factor for ATF-2/CREB and HO-1 regulation ( 1 , 25 ); and a reductase that catalyzes the conversion of biliverdin to bilirubin ( 27 ). These, together with the protein’s primary and secondary features, intimately link BVR to the entire spectrum of cell-signaling cascades.

Abstract:
Green sera collected from larval lampreys of Lampetra lamottenii were assayed and were shown to contain biliverdin at a concentration ranging from 141.5 to 305.0 μmol/L (mean 231.0 ± 27.4). These levels of serum biliverdin are compared with those of other lower vertebrates and with those observed during several human pathological conditions and are discussed with regard to the location of larval nematodes of Truttaedacnitis stelmioides within the bile ducts of these lampreys.

Abstract:
The later stages in the pathway of biosynthesis of phycocyanobilin, the chromophore of phycocyanin, were studied by using radiolabelled intermediates. Three possible pathways from biliverdin IX-alpha to phycocyanobilin were considered. 14C-labelled samples of key intermediates in two of the pathways, 3-vinyl-18-ethyl biliverdin IX-alpha and 3-ethyl-18-vinyl biliverdin IX-alpha, were synthesized chemically and were administered to cultures of Cyanidium caldarium that were actively synthesizing photosynthetic pigments in the light. Neither of these two compounds was apparently incorporated into

The Raman spectrum of a microsubstance, smeared on a fiber coming from the Shroud of Turin, was compared with numerous spectra published for old or modern pigment dyes, whole bloods, dried bloods, red blood cells, albumin, very ancient blood stains, and various “degradation” products of heme. Within the wavenumber measure accuracy, it is shown that all Raman lines detected above background could correspond to vibration frequencies found in biliverdin-derived compounds except a weak line that we tentatively attributed to amide I. Biliverdin is known as an oxidative ring cleavage product of the

Abstract:
Heme oxygenase (HO) catalyzes the degradation of heme to biliverdin, iron, and CO. The inducible isoform (HO-1) has been implicated as a modulator of the inflammatory response. HO-1 activity can be induced by hemin and inhibited with zinc protoporphyrin IX (ZnPP). Using these reagents, we assessed the possibility that HO-1 modulates the inflammatory response by altering the expression of endothelial cell adhesion molecules. Endotoxin (lipopolysaccharide, LPS)-induced expression of P- and E-selectin expression was quantified in different vascular beds of the rat using the dual radiolabeled mono

We and other investigators have reported that bilirubin and its precursor biliverdin may have beneficial effects on diabetic vascular complications, including nephropathy, via its antioxidant effects. Here, we investigated whether phycocyanin derived from Spirulina platensis, a blue-green algae, and its chromophore phycocyanobilin, which has a chemical structure similar to that of biliverdin, protect against oxidative stress and renal dysfunction in db/db mice, a rodent model for Type 2 diabetes.
