A paper in PNAS this week reporting that a signature of microRNA (miRNA) gene expression correlates with diagnosis and prognosis of B-cell chronic lymphocytic leukemias (CLLs) has drawn skepticism ...

Many key biological processes are impacted by miRNAs, including cell growth and proliferation, tissue differentiation, embryonic development, and apoptosis. Mutation, dysfunction, and/or dysregulation ...

Analyzing gene expression can provide a roadmap for deciphering the role of specific genes or elaborating critical players in functional metabolic pathways. Companies are pursuing solutions to better ...
