We have characterized a maize mutant, fuzzy tassel (fzt) with striking inflorescence and pleiotropic defects. fzt contains a mutation in the maize dicer-like1 homolog, a key enzyme required for microRNA (miRNA) biogenesis. By profiling the small RNA population in fzt mutants, we investigated the imp...

Objective. Microarray analysis was used to determine whether children with recent onset polyarticular juvenile idiopathic arthritis (JIA) exhibit biologically or clinically informative gene expression signatures in peripheral blood mononuclear cells (PBMC). Methods. Peripheral blood samples were o...

Hematopoietic stem cell (HSC) differentiation is regulated by cell-intrinsic and extrinsic cues. In addition to transcriptional regulation, post-translational regulation may also control HSC differentiation. To test this hypothesis, we visualized ubiquitin-regulated protein stability of a single tra...
