Expression data from jejunum IEC deleted for both HDAC1 and HDAC2
Both HDAC1 and HDAC2 are epigenetic erasers that drive specific and redundant gene expression patterns, in part by removing acetyl groups on histones. Deletion of these Hdac in intestinal epithelial cell (IEC) in vivo alters intestinal homeostasis, dependent on the Hdac deleted and the level of expression of both. To determine the intrinsic specific IEC function of HDAC1 and HDAC2, we have performed transcriptomic and quantitative proteomic approaches on IEC-deficient for Hdac1 and Hdac2. We have defined changes in both mRNA and protein expression patterns affecting IEC differentiation. We have identified IEC Hdac1- and Hdac2-dependent common as well as specific pathways and biological processes. These findings uncover unrecognized similarities and differences between normal IEC and HDAC1/2 deleted jejunum IEC. Overall design: Total RNAs from wild-type and HDAC1/2-deleted IEC were purified with the RNeasy mini kit (Qiagen), and quantified with a NanoDrop ND-1000 spectrophotometer (Thermo Fisher Scientific).
