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...

Designing effective small-interfering RNAs (siRNAs) for gene silencing requires considering RNA secondary structures. The OligoWalk software helps design efficient siRNAs by analyzing these structures in both the siRNA and target mRNA.

Area of Science:

  • Molecular Biology
  • Bioinformatics

Background:

  • RNA interference (RNAi) is a key tool in biological research and therapeutics.
  • Small-interfering RNAs (siRNAs) are utilized to reduce specific messenger RNA (mRNA) expression.
  • siRNA efficacy is influenced by various factors, including RNA secondary structure.

Purpose of the Study:

  • To present protocols for designing efficient siRNAs using the OligoWalk software.
  • To highlight the importance of considering RNA secondary structures in siRNA design.

Main Methods:

  • Utilizing the OligoWalk software package for siRNA design.
  • Analyzing self-structures of both siRNA sequences and target mRNA binding sites.
  • Considering local sequence features in the design process.
