Research Description

o Dr. Arthur’s research is focused on understanding the epigenetic role of non-coding RNAs (ncRNAs) in the pathogenesis of acute lymphoblastic leukemia through the computational analysis of next-generation sequencing data provided by Dr. Kristen Taylor. This data contains extensive, high-dimensional information about the genomic locations and amount of DNA methylation present in this malignancy versus normal lymphoblasts. The central importance of ncRNAs in the regulation of the expression of genes at times and amounts appropriate for proper cellular development and function has only recently been recognized. The elucidation of the molecular mechanisms enabling these ncRNA functions promises to provide significant insights into the classification and treatment of this and other diseases. In particular, it is conceivable that the informatics studies of Dr. Arthur will identify specific sequences within ncRNA genes and expressed RNA that may serve as therapeutic targets for antisense oligonucleotides and other nanomedical reagents.
