Analysis of RNA-Seq Data Using TopHat and Cufflinks
The recent advances in high throughput RNA sequencing (RNA-Seq) have generated huge amounts of data in a very short span of time for a single sample. These data have required the parallel advancement of computing tools to organize and interpret them meaningfully in terms of biological implications, at the same time using minimum computing resources to reduce computation costs. Described here is the method of analyzing RNA-seq data using the set of open source software programs of the Tuxedo suite: TopHat and Cufflinks. TopHat is designed to align RNA-seq reads to a reference genome, while Cufflinks assembles these mapped reads into possible transcripts and then generates a final transcriptome assembly. Cufflinks also includes Cuffdiff, which accepts the reads assembled from two or more biological conditions and analyzes their differential expression of genes and transcripts, thus aiding in the investigation of their transcriptional and post transcriptional regulation under different conditions. Also ...

MiniQuant – improving the accuracy of isoform quantification
RNA sequencing has revolutionized the way scientists study gene expression, helping researchers identify not just which genes are active but also which isoforms, alternative versions of RNA produced from the same gene, are being expressed. This is especially important because different isoforms can have very different roles in health and disease. However, accurately quantifying these isoforms has remained a challenge, particularly when relying on short-read sequencing. Short-read RNA sequencing technologies are widely used due to their high throughput and relatively low cost. But these reads are often too short to uniquely identify and assemble the full structure of complex isoforms, especially in genes with multiple exons or alternative splicing events. This can lead to quantification errors and misinterpretation of results. To address this issue, researchers from the University of Michigan have developed miniQuant, a computational method that significantly improves the accuracy of isoform quantification. Instead of relying solely on ...

ARPIR – automatic RNA-Seq pipelines with interactive report
RNA-Seq is an increasing used methodology to study either coding and non-coding RNA expression. There are many software tools available for each phase of the RNA-Seq analysis and each of them uses different algorithms. Furthermore, the analysis consists of several steps regarding alignment (primary-analysis), quantification, differential analysis (secondary-analysis) and any tertiary-analysis and can therefore be time-consuming to deal with each step separately, in addition to requiring a computer knowledge. For this reason, the development of an automated pipeline that allows the entire analysis to be managed through a single initial command and that is easy to use even for those without computer skills can be useful. Faced with the vast availability of RNA-Seq analysis tools, it is first of all necessary to select a limited number of pipelines to include. For this purpose, University of Perugia researchers compared eight pipelines obtained by combining the most used tools and for each one ...
