A low-molecular-weight compound K7174 represses hepcidin: possible therapeutic strategy against anemia of chronic disease.

Hepcidin is the principal iron regulatory hormone, controlling the systemic absorption and remobilization of iron from intracellular stores. The expression of the hepcidin gene, HAMP, is increased in patients with anemia of chronic disease. Previously, the synthetic compound K7174 was identified through chemical screening as a novel inhibitor of the adhesion of monocytes to cytokine-stimulated endothelial cells.

2,4-Dinitrofluorobenzene-induced contact hypersensitivity response in NC/Nga mice fed fructo-oligosaccharide.

Strategies to manipulate gut microbiota in infancy have been considered to prevent the development of allergic diseases later in life. We previously demonstrated that maternal dietary supplementation with fructo-oligosaccharide (FOS) during pregnancy and lactation modulated the composition of gut microbiota and diminished the severity of spontaneously developing atopic dermatitis-like skin lesions in the offspring of NC/Nga mice. The present study tested whether dietary FOS affects contact hypersensitivity (CHS), another model for allergic skin disease, in NC/Nga mice.
