RNA-seq03:21

RNA-seq

10.2K
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...

Ribosome Profiling02:24

Ribosome Profiling

3.6K
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...

    Area of Science:

    • Genomics and Molecular Biology
    • Bioinformatics and Computational Biology

    Background:

    • Long non-coding RNAs (LncRNAs) are crucial regulators of gene expression and cellular processes.
    • Accurate identification of lncRNAs is essential for understanding disease mechanisms and developing therapies.
    • Existing methods like bio-sequencing and traditional machine learning have limitations, including tedious feature extraction and potential artifacts.

    Purpose of the Study:

    • To develop a novel deep learning framework, lncDLSM, for differentiating lncRNAs from protein-coding transcripts.
    • To overcome the limitations of existing lncRNA identification methods by eliminating the need for prior biological knowledge.
    • To assess the applicability and performance of lncDLSM across different species using transfer learning.

    Main Methods:

    • Development of lncDLSM, a deep learning-based framework for lncRNA identification.
    • Evaluation of lncDLSM's performance against traditional biological feature-based machine learning methods.
    • Application of transfer learning to test lncDLSM's efficacy in identifying lncRNAs across different species.

    Main Results:

    • lncDLSM successfully differentiates lncRNAs from protein-coding transcripts without relying on prior biological information.
    • The deep learning framework demonstrates superior performance compared to existing biological feature-based machine learning approaches.
    • Transfer learning enables lncDLSM to achieve satisfactory results in identifying lncRNAs across diverse species, highlighting species-specific distribution patterns.

    Conclusions:

    • lncDLSM provides an efficient and accurate tool for lncRNA identification, advancing the field of non-coding RNA research.
    • The framework's independence from biological knowledge makes it broadly applicable and adaptable.
    • The study reveals distinct inter-species variations in lncRNA distribution, offering insights into evolutionary conservation and specificity.
