RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

miRSeqNovel is a new R-based workflow for analyzing miRNA sequencing data. It identifies differentially expressed microRNAs (miRNAs) and predicts novel miRNA candidates from various sequencing platforms.

Area of Science:

  • Bioinformatics
  • Genomics
  • Computational Biology

Background:

  • MicroRNA (miRNA) sequencing is crucial for understanding gene regulation.
  • Existing analysis workflows may lack flexibility for diverse sequencing data.
  • Accurate identification of novel miRNAs is essential for biological discovery.

Purpose of the Study:

  • To introduce miRSeqNovel, an R-based workflow for miRNA sequencing data analysis.
  • To enable processing of both colorspace (SOLiD) and basespace (Illumina/Solexa) data.
  • To provide a robust method for identifying differentially expressed miRNAs and novel miRNA candidates.

Main Methods:

  • Development of an R-based bioinformatics workflow.
  • Integration of multiple mapping algorithms for sequence alignment.
