Novo Custom scripts (Beijing Novo Gene Genomics Institute, China) were used to obtain the miRNA counts as well as base bias on the first position of identified miRNA with certain length and on each position of all identified miRNA respectively.
To test if any correlation between miRNAs and their targets existed, the expression patterns of identified miRNA targets based on quantitative RT-PCR (qRT-PCR) were compared.
Since predictions are based on identifying miRNA precursors, genomic regions (70 nucleotides) surrounding the sRNA sequences were extracted (see "Methods" for details).
Subsequently, we analyzed the base bias on the first position of identified miRNAs with certain length and on each position of all identified miRNAs, respectively.
According to the results, we analyzed the base bias on the first position of identified miRNAs with certain length and on each position of all identified miRNAs respectively.
We aligned the small RNA to the miRNA precursor of corresponding species (using mature miRNA if there was no precursor information of that species in miRBase14.0) to obtain the miRNA count as well as base bias on the first position of identified miRNAs with certain lengths and on each position of all identified miRNAs respectively.
In Chen et al.'s study, it mainly focused on identifying miRNAs in porcine backfat tissues.
In the literature of computational analysis of miRNAs, the two main focuses have long been on identifying miRNA-encoding regions from genomes [ 33– 36] and on predicting the targets of individual miRNAs [ 37, 38].
Through an arrangement with a local slaughterhouse, we were able to isolate retinas and perform UV-induced cross-linking within 1 h of the death of an animal, minimizing the impact of post-mortem changes in gene expression on the identified miRNA target genes.
The advantage of using miRTI over Corrmir, Seq and W to identify miRNA influence on target partners or on patient gene expression is that it produces two types of modules, unlike W that favors the first type of modules and Corrmir that favors the second type of module.
