Dataset Summary
TitleQuantitative proteomics and RNA-sequencing of mouse liver endothelial cells identify novel regulators of BMP6 by iron
DescriptionIron induces hepcidin by activating bone morphogenetic protein (BMP)6-SMAD signaling. Liver endothelial cells (LECs) produce BMP6, but the molecular mechanisms are incompletely understood. To address this, we performed proteomics and RNA-sequencing on LECs from iron-adequate and iron-loaded mice. Gene set enrichment analysis identified transcription factors activated by high iron, including Nrf-2, which was previously reported to contribute to BMP6 regulation, and proto-oncogene c-Jun (encoded by Jun). Jun knockdown blocked Bmp6, but not Nrf-2 pathway, induction by iron in LEC cultures. Moreover, chromatin immunoprecipitation of mouse livers showed iron-dependent c-Jun binding to predicted sites in Bmp6 regulatory regions. Finally, c-Jun inhibitor blunted induction of Bmp6 and hepcidin, but not Nrf-2 activity, in iron-loaded mice. However, Bmp6 expression and iron parameters were unchanged in endothelial Jun knockout mice. Our data suggest that c-Jun participates in iron-mediated BMP6 regulation independent of Nrf-2, though the mechanisms may be redundant and/or multifactorial.
