Fpn hepcidin
WebHepcidin exerts its biologic effect by binding FPN, which causes the latter to be internalized and degraded, thus halting iron export into the circulation. 21 When there is excess iron … WebHepcidin, a peptide hormone produced by the liver, plays a pivotal role for systemic Fe homeostasis by regulating the activity of Fpn. High Fe levels and inflammation increase hepcidin expression followed by internalization and degradation of the hepcidin–Fpn complex ( Tussing-Humphreys, Pusatcioglu, Nemeth, & Braunschweig, 2012 ).

WebNational Center for Biotechnology Information WebFeb 7, 2024 · Hepcidin is emerging as a new important factor in brain iron homeostasis. Studies suggest that there are two sources of hepcidin in the brain; one is local and the other comes from the circulation. Little is known about the molecular mediators of local hepcidin expression, but inflammation and iron-load have been shown to induce …
WebApr 12, 2014 · In the current study, we demonstrated that STZ-induced hypoinsulinemia significantly reduced hepcidin expression in the liver, leading to an abnormally high content of Fpn in the intestine and … WebHepcidin could prevent erastin-induced ferroptosis by degrading Fpn. Erastin (5 μg/mL) was observed to induce ferroptosis in neuroblastoma cells at 6 hours, which was promoted by knockdown of Fpn. The expression of Fpn gene and protein was decreased in SH-SY5Y cells treated with erastin.
