A Novel Method to Detect Identities in tRNA Genes Using Sequence
... We applied the method to Class I tRNAs to detect characteristic sites. We found that about 40% of characteristic sites that we detected are identities that have been detected experimentally, and that the remaining characteristic sites are in T and D domains which are the elbow regions of tRNAs. This ...

Conversely, retinoic acid (RA) has been shown to increase CYP4B1 gene expression in ocular organ cultures, resulting in increased metabolism of arachidonic acid to 12-HETE and 12-HETrE (Ashkar et al., 2004). These effects were shown to be mediated, at least in part, by transcriptional regulation of ...
