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...
Ribosome Profiling02:24

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique helps...

RACE - Rapid Amplification of cDNA Ends

Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.
Since the...

RNA Structure

Overview
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...

Area of Science:

  • Molecular Biology
  • Bioinformatics
  • Computational Biology

Background:

  • Messenger RNA (mRNA) contains functional elements within its coding regions that regulate post-transcriptional processes.
  • These functional elements are often encoded by RNA secondary structures.
  • Understanding mRNA secondary structure is crucial for deciphering gene regulation.

Purpose of the Study:

  • To introduce Structural Profile Assignment of RNA Coding Sequences (SPARCS), an efficient method for analyzing mRNA secondary structure profiles.
  • To develop a novel algorithm for uniform sampling of mRNA sequence landscapes.
  • To predict structured and unstructured regions within mRNA coding sequences.

Main Methods:

  • Developed a novel algorithm for uniform sequence landscape sampling, preserving dinucleotide frequency and amino acid sequence.
  • Utilized the sampling algorithm to generate artificial sequences for Z-score estimation of structural metrics.
  • Employed base pairing probabilities and base pairing entropy to predict structured/unstructured regions.

Main Results:

  • Successfully applied SPARCS to analyze the structural profile of ASH1 genes.
  • Identified key structural elements within the studied mRNA sequences.
  • Developed a web server and released source code for the SPARCS pipeline.

Conclusions:

  • SPARCS provides an efficient method for analyzing mRNA secondary structure profiles.
  • The method enables the prediction of functional structured and unstructured regions in mRNA.
  • This tool aids in understanding the role of RNA structure in gene regulation.
