Background: The gut microbiome and iron status are known to play a role in the pathophysiology of nonalcoholic fatty liver disease (NAFLD), although their complex interaction remains unclear. Results: Here, we applied an integrative systems medicine approa ...

Mechanistic insights into AMP-activated protein kinase-dependent gene expression

Caterina Collodet

AMP-activated protein kinase (AMPK) is a fundamental enzyme that controls energy homeostasis, through orchestrating the cellular response to a reduction in energy availability. Under conditions of cellular energy stress AMPK senses the decrease in ATP leve ...

Iron regulatory proteins and their role in controlling iron metabolism

Cellular iron homeostasis is regulated by post-transcriptional feedback mechanisms, which control the expression of proteins involved in iron uptake, release and storage. Two cytoplasmic proteins with mRNA-binding properties, iron regulatory proteins 1 and ...

Royal Soc Chemistry2015

Ferritin plays a central role in iron metabolism and is made of 24 subunits of 2 types: heavy chain and light chain. The ferritin heavy chain (FtH) has ferroxidase activity that is required for iron incorporation and limiting toxicity. The purpose of this ...

Metabolic Adaptation to Tissue Iron Overload Confers Tolerance to Malaria

Liviu Vanoaica

Disease tolerance is a defense strategy that limits the fitness costs of infection irrespectively of pathogen burden. While restricting iron (Fe) availability to pathogens is perceived as a host defense strategy, the resulting tissue Fe overload can be cyt ...

Intestinal ferritin H is required for an accurate control of iron absorption

Lukas Kühn, Liviu Vanoaica

To maintain appropriate body iron levels, iron absorption by the proximal duodenum is thought to be controlled by hepcidin, a polypeptide secreted by hepatocytes in response to high serum iron. Hepcidin limits basolateral iron efflux from the duodenal epit ...

Analysis of mice with conditional ferritin H deletion

Liviu Vanoaica

Iron is a transitional metal required by virtually all organisms as a dietary micromineral, indispensable for cellular survival and proliferation. The management of iron absorption and distribution in the organism and inside the cell must be tightly regula ...

Ferritin plays a central role in iron metabolism by acting both as iron storage and detoxifying protein. We have generated a ferritin H allele with loxP sites and studied the conditional ferritin H deletion in adult mice. Ten days after Mx-Cre induced dele ...

2009

Insects, like vertebrates, express iron regulatory proteins (IRPs) that may regulate proteins in cellular iron storage and energy metabolism. Two mRNAs, an unspliced form of ferritin H mRNA and succinate dehydrogenase subunit b (SDHb) mRNA, are known to co ...

Determination of drug binding sites to proteins by electrospray ionisation mass spectrometry: the interaction of cisplatin with transferrin

Paul Joseph Dyson, Claire Samantha Allardyce

Cisplatin, CiS-[PtCl2(NH3)(2)], is known to bind to human serum transferrin, but the binding site remains a matter of some debate. Electrospray ionisation mass spectrometry has been used to characterise the interaction of cisplatin with transferrin. The st ...
