Abstract (sommario):

Iron, known for its versatility, is an essential element in the metabolism of mammalian cells. One of the most common iron disorders is autosomal recessive disease---hereditary hemochromatosis, which leads to the iron overload in population of northern European descent. During years of my graduate research, I focused on the study of Hemochromatosis gene Hfe and a point mutation C282Y that leads to more than 80% of all hemochromatosis cases.<br>Iron Regulatory Proteins (IRPs), which serve as main posttranscriptional regulators of cellular iron homeostasis, are the other interest of resea

Abstract (sommario):

Organisms depend on iron to survive. This fact is underscored by the critical requirement for iron during DNA synthesis and as a cofactor in proteins involved in respiration and oxygen transport. However, when present in excess of cellular requirements, iron can be toxic, due to its ability to generate reactive oxygen species and induce oxidative stress. The physiological significance of iron renders it a target for the development of iron chelators as therapeutic agents and highlights the potential problems that can occur when iron regulatory pathways are disturbed in disease.

In solid phase binding assays, total membranes from only two (9L and 642A) of the five strains, grown under iron-restricted conditions, were able to bind Tfs (ovine, bovine and goat, but not porcine or human). However, when the organisms were grown under iron-restricted conditions in the presence of bovine Tf, total membranes from all strains exhibited Tf binding (a

Growth assays with porcine, bovine and human Tfs and Hbs revealed that all seven strains could use porcine (but not human or bovine) Tf and all three Hbs as iron sources. In solid phase binding assays, membranes derived from all strains exhibited strong binding of porcine Tf and each of the Hbs. Competition binding assays indicated that all three Hbs were bound by the same receptor(s).

Iron is a crucial element that is associated with many metabolic pathways important for life sustaining processes. Polyamines are small positively charged polycations involved in various physiological functions. Both iron and polyamines levels are known to be high in cancer cells which suggests a possible unexplored link between the two metabolic pathways. For the first time, we demonstrate that iron-depletion robustly regulates the expression of 13 polyamine pathway proteins. Iron-depletion also decreased polyamine and S-adenosylmethionine levels (required for spermidine/spermine biosynthesi

<p>Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. The flexible redox state of iron makes it ideal to contribute in single electron transfers, but may also catalyze reactions with oxygen resulting in cell damaging reactive oxygen species (ROS). Normally the cells are protected against iron toxicity by controlling iron uptake and storage. When the intra

Abstract (sommario):

Staphylococcus aureus requires iron as a nutrient and uses uptake systems to extract iron from the human host. S. aureus produces the iron-chelating siderophore staphyloferrin B (SB) to scavenge for available iron under conditions of low iron stress. Upon iron-siderophore re-entry into the cell, iron is separated from the siderophore complex to initiate assimilation into metabolism. To gain insight into how SB biosynthesis is integrated into S. aureus central metabolism, the three SB precursor biosynthetic proteins, SbnA, SbnB, and SbnG, were biochemically characterized.

Abstract (sommario):

The pathogenic bacterium Pseudomonas aeruginosa uses a variety of highly efficient chelating compounds (siderophores) to acquire sufficient iron for growth and virulence. These siderophores can either be endogenous or acquired from exogenous sources such as other bacteria or fungi. The transport of the endogenous siderophore pyoverdine activates a signal-transduction pathway that increases the synthesis of both the ferripyoverdine receptor protein (FpvA) and pyoverdine itself. Signal-transduction systems similar to this have three specific proteins involved: a receptor protein specific for one

Abstract (sommario):

Thesis (PhD)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: Iron is an essential micronutrient that is an absolute requirement for correct cellular function in all eukaryotic organisms. However, ferrous iron has the ability to catalyze the formation of potentially toxic reactive oxygen species and regulation of iron metabolism is therefore of critical importance. Currently, there is little known about the co-ordinated regulation of the plethora of genes coding for proteins involved in this biochemical pathway, with the exception of the well characterized post-transcriptional IRE/IRP
