JmjD2d-dependence of LPS-induced genes


ABSTRACT: In dendritic cells, expression of the H3K9me3 demethylase JmjD2d is upregulated by LPS stimulation. To identify genes whose induction by LPS depends on JmjD2d activity, we performed a microarray analysis of wild-type and JmjD2d-knockdown dendritic cells, before and after stimulation with LPS. RNA was extracted from three independent cultures of wild-type and JmjD2d-knockdown dendritic cells, before and 4h after stimulation with 100ng/ml LPS. The unstimulated and stimulated wild-type samples, and the stimulated JmjD2d-knockdown samples, were used for microarray analysis.

Cell-type-specific control of enhancer activity by H3K9 trimethylation.

Cell-type-specific control of gene expression is critical for the development of multicellular organisms. To investigate the mechanisms which underlie this, we have studied the regulation of the model genes Mdc and Il12b, whose stimulus-induced expression is tightly restricted to specific cells of the immune system. Surprisingly, we find that neither the promoter nor the enhancer sequences of these genes are sufficient to direct this cell-type specificity. Instead, the activities of upstream enh  ...[more]
