Regulation of the expression of ferrochelatase in a murine model of diabetes mellitus type I

open access: yesBiochemistry and Biophysics Reports
Background: Diabetes produces changes on cellular hemeprotein metabolism. The last enzyme of heme biosynthetic pathway is ferrochelatase (FECH), an enzyme that catalyzes the insertion of ferrous ion into protoporphyrin IX to produce heme. The aim of this

Collagenous bone matrix-induced endochondral ossification hemopoiesis. [PDF]

open access: yes, 1976
Transplantation of collagenous matrix from the rat diaphyseal bone to subcutaneous sites resulted in new bone formation by an endochondral sequence. Functional bone marrow develops within the newly formed ossicle.

Permeability of rat choriocapillaris to hemeproteins. Restriction of tracers by a fenestrated endothelium. [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 1981
The choriocapillaris is the fenestrated capillary bed in the choroid of the eye and is the major blood supply to the retinal pigment epithelium (RPE) and photoreceptor cells. Bruch's membrane (BM) is a multilaminated basement membrane that separates the choriocapillaris from the RPE. In a previous study (Pino RM, Essner E; Cell Tissue Res 208:21, 1980)

A framework for protein classification [PDF]

open access: yes, 2003
It is widely understood that protein functions can be exhaustively described in terms of no single parameter, whether this be amino acid sequence or the three-dimensional structure of the underlying protein molecule. This means that a number of

Peptide-oligonucleotide conjugates as nanoscale building blocks for assembly of an artificial three-helix protein mimic [PDF]

open access: yes, 2016
Peptide-based structures can be designed to yield artificial proteins with specific folding patterns and functions. Template-based assembly of peptide units is one design option, but the use of two orthogonal self-assembly principles, oligonucleotide ...

Structure-Guided Directed Evolution of Highly Selective P450-Based Magnetic Resonance Imaging Sensors for Dopamine and Serotonin [PDF]

open access: yes, 2012
New tools that allow dynamic visualization of molecular neural events are important for studying the basis of brain activity and disease. Sensors that permit ligand-sensitive magnetic resonance imaging (MRI) are useful reagents due to the noninvasive ...

A quantitative model for oxygen uptake and release in a family of hemeproteins

open access: yesBioinformatics, 2016
Abstract Motivation: Hemeproteins have many diverse functions that largely depend on the rate at which they uptake or release small ligands, like oxygen. These proteins have been extensively studied using either simulations or experiments, albeit only qualitatively and one or two proteins at a time.
