Aging is associated with increased brain iron through cortex-derived hepcidin expression

eLife, 2022
Iron is an essential molecule for biological processes, but its accumulation can lead to oxidative stress and cellular death. Due to its oxidative effects, iron accumulation is implicated in the process of aging and neurodegenerative diseases.

Pulsed Electric Field (PEF) Enhances Iron Uptake by the Yeast Saccharomyces cerevisiae

Biomolecules, 2021
The aim of the study was to investigate the influence of a pulsed electric field (PEF) on the level of iron ion accumulation in Saccharomyces cerevisiae cells and to select PEF conditions optimal for the highest uptake of this element.

Different Forms Of Iron Accumulation In The Liver On Mri [PDF]

, 2016
Magnetic resonance imaging (MRI) is a well-established imaging modality to evaluate increased iron deposition in the liver. Both standard liver imaging series with in-phase and out-of-phase T1-weighted sequences for visual detection, as well as advanced ...

Excessive iron accumulation mediated oxidative stress and β-cell dysfunction via perturbations of insulin secretion in MIN6 cells [PDF]

, 2020
Type 2 diabetes mellitus (T2DM) is the predominant form of diabetes, with prevalence increasing steadily both in developed and developing countries. Defects in both insulin action and insulin secretion are known to contribute to the development of T2DM ...

Benefits and risks of iron supplementation in anemic neonatal pigs. [PDF]

, 2010
Iron deficiency is a common health problem. The most severe consequence of this disorder is iron deficiency anemia (IDA), which is considered the most common nutritional deficiency worldwide. Newborn piglets are an ideal model to explore the multifaceted

Leucine encoding codon TTG shows an inverse relationship with GC content in genes involved in neurodegeneration with iron accumulation

Journal of Integrative Neuroscience, 2021
We determined various forces involved in shaping codon usage of the genes linked to brain iron accumulation and infantile neuroaxonal dystrophy. The analysis paved the way for determining the forces responsible for composition, expression level, physical

Correction of the iron overload defect in beta-2-microglobulin knockout mice by lactoferrin abolishes their increased susceptibility to tuberculosis. [PDF]

, 2002
As a resident of early endosomal phagosomes, Mycobacterium tuberculosis is connected to the iron uptake system of the host macrophage. beta-2-microglobulin (beta2m) knockout (KO) mice are more susceptible to tuberculosis than wild-type mice, which is ...
