ChIP-seq analysis to examine the effect of the iron chelator deferoxamine on histone methylation levels in 3T3-L1 pre-adipocyte cells

ABSTRACT: Adipocyte differentiation has been shown to require iron, but the underlying mechanism remains elusive. Ferrous iron ion is known to function as a co-factor for alpha-ketoglutarate-dependent dioxygenases, including demethylases for histones, DNA, and RNA. Previously we reported several alpha-ketoglutarate-dependent histone demethylases as critical epigenetic regulators during adipogenesis. These lines of evidence led us to hypothesize that iron orchestrates epigenetic/epitranscriptional regulations during adipogenesis by controlling demethylation activities. In this study, we conducted genome-wide analysis on methylation landscapes of histones, DNA, and RNA in differentiation of 3T3-L1 pre-adipocytes. Using the iron chelator deferoxamine, we demonstrate here how dynamically methylation levels of histones, DNA, and RNA are regulated by iron during adipogenesis.
