Genome-wide analysis of YY2 versus YY1 target genes

ABSTRACT: Yin Yang 1 (YY1) is a critical transcription factor controlling cell proliferation, development and DNA damage responses. Although two homologous Drosophila YY family members (pleiohomeotic (pho)) and pleiohomeotic-like (phol)) are redundant, the functional significance of a recently described mammalian YY1-like gene (YY2) is unknown. Using microarray and gene set enrichment analysis (GSEA), we found that lentiviral constructs containing short hairpin loop YY1- and YY2-specific inhibitory RNAs (shYY1 and shYY2) caused significant changes in both redundant and distinguishable expression patterns. Ribosomal protein genes were the most significant gene set up-regulated by both shYY1 and shYY2, although combined shYY1/shYY2 knockdowns were not additive. In contrast, shYY2 reversed anti-prolife
