Maximum expected accuracy structural neighbors of an RNA secondary structure

Since RNA molecules regulate genes and control alternative splicing by allostery, it is important to develop algorithms to predict RNA conformational switches. Some tools, such as paRNAss, RNAshapes and RNAbor, can be used to predict potential conformational switches; nevertheless, no existent tool can detect general (i.e., not family specific) entire riboswitches (both aptamer and expression platform) with accuracy. Thus, the development of additional algorithms to detect conformational switches seems important, especially since the difference in free energy between the two metastable secondary structures may be as large as 15-20 kcal/mol. It has recently emerged that RNA secondary structure can be more accurately predicted by computing the maximum expected accuracy (MEA) structure, rather than the minimum free energy (MFE) structure.

microRNAs quantitative assay with Splinted Ligation

Do you still use Northern Blot to quantitate microRNAs expression? Here I recommend Splinted Ligation Assay[1,2], though this method is an old story (published in 2007).   Detection of miRNAs using splinted ligation. Schematic depiction of the assay process. As described in the text, the assay involves: (1) Labeling of the ligation oligonucleotide; (2) concurrent … Read moremicroRNAs quantitative assay with Splinted Ligation
