Transcription profiling of wild type and C/EBPbeta deficient mice during a partial hepatectomy time series to identify transcriptional targets of C/EBPbeta


ABSTRACT: The aim of this experiment was to use microarray analysis to compare the response of wild type (WT) and C/EBPbeta deficient (KO) mice during a partial hepatectomy time course in hopes of identifying transcriptional targets of C/EBPbeta. In addition, the WT time course alone was examined to analyze mammalian cellular proliferation in vivo. In the partial hepatectomy model, quiescent hepatocytes reenter the cell cycle and progress in a synchronous fashion. This allows for the elucidation of regulatory networks operative in mammalian cell cycle.

CCAAT enhancer-binding protein beta (C/EBPbeta), a basic-leucine zipper transcription factor, is an important effector of signals in physiologic growth and cancer. The identification of direct C/EBPbeta targets in vivo has been limited by functional compensation by other C/EBP family proteins and the low stringency of the consensus sequence. Here we use the combined power of expression profiling and high-throughput chromatin immunoprecipitation to identify direct and biologically relevant target  ...[more]
