Biological relevance and therapeutic potential of G-quadruplex structures in the human noncoding transcriptome

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• Noncoding RNAs are key regulators of gene expression in various cellular conditions.
• While progress has been made, the precise roles and mechanisms of many noncoding RNAs remain unclear.
• RNA structures, beyond sequence, enable complex interactions with proteins and nucleic acids.

Purpose of the Study:

• To review the current understanding of G-quadruplexes within the noncoding transcriptome.
• To explore the structural and functional characteristics of RNA G-quadruplexes.
• To discuss the therapeutic implications of targeting G-quadruplexes in noncoding RNAs for disease intervention.

Main Methods:

• Literature review of studies on noncoding RNAs and G-quadruplexes.
• Analysis of structural and functional data related to RNA G-quadruplexes.
• Discussion of potential therapeutic strategies targeting G-quadruplexes.

Main Results:

• G-quadruplex structures are increasingly found in microRNAs and long noncoding RNAs.
• These structures play roles in microRNA biogenesis and interactions with biological partners.
• RNA G-quadruplexes are implicated in regulating gene expression.

Conclusions:

• RNA G-quadruplexes are significant structural motifs in the noncoding transcriptome.
• Understanding these structures is crucial for elucidating noncoding RNA function.
• G-quadruplex binders represent a promising therapeutic avenue for diseases linked to aberrant noncoding RNAs.
