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...
Real Time RT-PCR02:57

Real Time RT-PCR

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...
Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Non-coding RNAs (ncRNAs) play crucial roles in cellular processes, necessitating efficient computational prediction methods.
  • Current ncRNA detection tools lack reliability and standardization, hindering effective combination and comparison.
  • Genomic scans require custom scripting for existing tools, impacting transparency and reproducibility.

Purpose of the Study:

  • To develop a Java-based framework for integrating and comparing existing ncRNA detection tools.
  • To enhance the transparency, reproducibility, and efficiency of ncRNA detection workflows.
  • To improve the precision and sensitivity of ncRNA detection through method combination.

Main Methods:

  • Development of a Java-based framework for integrating diverse ncRNA detection tools.
  • Construction of transparent detection workflows for combining and comparing methods.
  • Application of the framework to small bacterial genomes (E. coli, L. monocytogenes, S. pyogenes).

Main Results:

  • Achieved 10% to 20% precision gains for sensitivities ranging from 30% to 80% by combining methods.
  • Identified four highly probable novel ncRNA candidates in Streptococcus pyogenes.
  • Experimentally verified all four novel ncRNA candidates using RT-PCR.

Conclusions:

  • An extensible framework for practical, transparent, and reproducible ncRNA detection method combination has been created.
  • The framework's effectiveness is demonstrated by improved detection rates and the discovery of new ncRNAs.
  • The software is freely available, promoting wider adoption and research in ncRNA detection.
