RNA-seq03:21

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...
Nonsense-mediated mRNA Decay02:27

Nonsense-mediated mRNA Decay

The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Area of Science:

  • Bioinformatics
  • Molecular Biology
  • Genomics

Background:

  • High-throughput sequencing generates vast amounts of biological data, particularly small regulatory RNAs involved in transposable element (TE) control.
  • Existing databases contain extensive small RNA sequence data, but are largely unexplored due to difficult-to-use analytical tools.

Purpose of the Study:

  • To develop NucBase, a novel software program designed for efficient searching and alignment of short sequence reads from large nucleic acid databases.
  • To provide biologists with an accessible tool for exploring small RNA data and its role in biological systems.

Main Methods:

  • NucBase utilizes an exhaustive search algorithm for sequence matching and alignment.
  • Features a graphical interface for ease of use, enabling visualization of sequence matches, counts, and genomic positions.
  • Capable of identifying exact matches and candidates with mismatches, including "core sequences" of consecutive matching nucleotides.

Main Results:

  • NucBase successfully performs exhaustive searches and alignments of short sequence reads against large databases.
  • The software provides intuitive visualization of sequence match data, including location and quantity.
  • Identifies both exact and near-matches, offering flexibility in sequence analysis.

Conclusions:

  • NucBase is an easy-to-use software that enhances the discovery of small non-coding RNAs involved in transposable element silencing.
  • The tool simplifies the exploration of small nucleic acid sequences across various organisms, benefiting a wider research community.
