NCOA4 Mediates Mobilization of Hepatic Iron Stores after Blood Loss
The intracellular protein NCOA4 mediates the autophagic degradation of ferritin in vitro (Mancias et al., Nature 2014; Dowdle et al., Nat Cell Biol 2014); mice with global Ncoa4 disruption show hyperferremia, microcytic anemia, and ferritin accumulation in multiple organs, including liver (Bellelli et al., Cell Rep 2016). Here, we dissect the requirement for NCOA4 in hepatic iron mobilization after acute blood loss, using Ncoa4-targeting siRNA that was conjugated to triantennary N-acetylgalactosamine (GalNAc-Ncoa4 siRNA) to promote uptake by hepatocytes. On experimental day 0, 8-week-old female C57BL/6N mice underwent a si...
