These include functional genomics, dynamic analysis of the transcriptome, metabolic and regulatory networks. Computational functional genomics-based approaches in analgesic drug discovery and repurposing. The common algorithms also do not take into account the expression pattern of miRNAs and the predicted target genes, and so will include functionally irrelevant predictions, in cases where the miRNA and mRNA are never co-expressed. This section aims to rapidly publish new methods, research findings, opinions, and hypothesis articles on all aspects of the discipline. Research in whole genome analyses include finding genes and pseudogenes, assigning protein structures and functions to known genes, and comparing genomes in terms of a wide variety of features. Because many mRNAs have been under selective pressure to preserve pairing to a 6-mer in the 5′ region of the miRNA known as the miRNA seed (nucleotides 2–7), targets of metazoan miRNAs can be predicted above the background of false positives by searching for conserved matches to the seed region [14–18]. As such they are unlikely to uncover unusual miRNA target interactions; for example, it is possible that miRNAs are able to mediate translational repression through sites outside of the 3′UTR [41]. Functional Genomics. The miRNA then acts as the specificity determinant of the silencing complex, hybridizing to complimentary sequences in the 3′UTRs of target mRNAs.
