The study, in which only the pathways with average IPA score >2 (−log (P value)) were included, revealed that the most probable genes modified by these miRNA correspond to pathways directly related to RA (that is, the role of macrophages, fibroblasts and endothelial cells in RA, the role of osteoblasts, osteoclasts and chondrocytes in RA, and the role of IL-17A in RA).
By analyzing the most probable gene sets for each topic, we can infer its underlying biological theme.
The most probable gene sets in most of the topics learned by the model are coherent, and the topics taken together describe a wide range of processes.
Recently, however, it was shown that with 4 taxa the most probable gene tree does not necessarily reflect the species tree, if the species tree is unbalanced [ 16].
However, even in the presence of lineage sorting, for 3 species the most probable gene tree represents the species tree [ 16].
The results of all analyses were written as sequence features in EMBL format and combined under Artemis to design most probable gene models.
Furthermore, the most probable gene tree can have a different topology from that of the species tree if multiple branch lengths are small enough in coalescent units [ 16].
The most probable gene tree has the topology (((A,B), C,D)),E) and the RF distance between the true species tree and the most probable gene tree is 2. The generated gene trees were then used as data to infer the species tree using MP-EST, STAR, and RT.
We conducted the re-annotation of the IPO323 genome using a pipeline that identifies the most probable gene models based on information from transcript assemblies, homology searches, and ab initio gene predictors (Haas et al. 2011).
Furthermore, under some conditions, even the most probable gene tree topology may not be identical to the species tree topology (Degnan, 2013; Degnan and Rosenberg, 2006, 2009), a condition called 'the anomaly zone'.
There can be many false positives because the data are ambiguous and much thought often has to go into deducing the most probable gene structure based on the evidence available.
