Molecular mechanisms and function prediction of long noncoding RNA

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• The central dogma of gene expression traditionally views RNA as an information carrier from DNA to protein.
• Emerging evidence highlights diverse and critical roles for RNA beyond simple information transfer.
• Long noncoding RNAs (lncRNAs) are increasingly identified through transcriptomic analyses, suggesting significant biological functions.

Purpose of the Study:

• To review recent advancements in identifying long noncoding RNAs (lncRNAs).
• To summarize the known molecular functions and mechanisms of lncRNAs.
• To discuss computational methods developed for predicting lncRNA functions.

Main Methods:

• Review of recent literature on lncRNA identification and functional characterization.
• Analysis of studies detailing lncRNA molecular mechanisms.
• Compilation and categorization of computational approaches for lncRNA function prediction.

Main Results:

• Whole genome transcriptomic analyses have revealed numerous dynamically expressed lncRNAs.
• Many lncRNAs are implicated in a wide array of biological functions.
• The precise functions and mechanisms of most lncRNAs remain largely unknown.

Conclusions:

• Despite their growing identification, the functional landscape of lncRNAs is still largely unexplored.
• Computational methods are crucial for accelerating the functional annotation of lncRNAs.
• Further research into lncRNA functions is essential for a comprehensive understanding of gene expression.
