Abstract
Z-DNA, the alternative form of double-stranded DNA involved in a variety of nucleotide metabolism, is recognized and stabilized by specific Z-DNA binding proteins (ZBPs). Three ZBPs known in vertebrates --ADAR1, DAI and PKZ-- modulate innate immunity, particularly, the IFN-induced immune response. The E3L protein of vaccinia virus appears to compete with the host ZBP for Z-DNA binding, thereby suppressing the host immune system. ZBPs are, therefore, considered to be attractive therapeutic targets for infectious and immune diseases. Recent advances in computer-aided drug development combined with the high-resolution crystal and NMR structures of ZBPs have enabled us to discover novel candidates for ZBP inhibitors. In this study, we present an overview of Z-DNA and known ZBPs as drug targets, and summarize recent progress in the structure-based identification of ZBP inhibitors.

RNA Molecules in the Treatment of Human Diseases
Messenger and non-coding RNAs, including long and small transcripts, are mediators of gene expression. Gene expression at the RNA level shows significant aberrations in human diseases, including cancer, leukemia, lymphoma, cardiovascular diseases, and neurological disorders. Human transcripts serve either as biomarkers of diagnosis, prognosis, prediction of treatment response, and/or therapy ...read more
