How snoRNAs can contribute to cancer at multiple levels

Area of Science:

• Molecular Biology
• RNA Biology
• Cancer Research

Background:

• Small nucleolar RNAs (snoRNAs) are non-coding RNAs essential for guiding RNA modifications like 2'-O-methylation and pseudouridylation.
• Altered snoRNA expression is increasingly linked to cancer, suggesting potential diagnostic and prognostic value.
• Previous studies often lacked consistent validation and mechanistic understanding of snoRNA's role in neoplasia.

Purpose of the Study:

• To critically review the literature on snoRNAs in cancer.
• To focus on studies elucidating the functional consequences of snoRNA deregulation in cancer.
• To explore both canonical and non-canonical roles of snoRNAs in the neoplastic process.

Main Methods:

• Literature review and critical analysis of published studies.
• Focus on research investigating functional consequences of snoRNA alterations.
• Inclusion of studies examining diverse roles of snoRNAs beyond canonical functions.

Main Results:

• Evidence suggests snoRNAs are involved in RNA processing and modification, with altered expression in various cancers.
• Functional studies reveal snoRNA deregulation contributes to neoplastic processes.
• Emerging roles of snoRNAs in cancer, beyond their guide function, are being uncovered.

Conclusions:

• SnoRNAs represent promising cancer biomarkers, but further research is needed to validate their clinical utility.
• Understanding the functional impact of snoRNA alterations is crucial for deciphering their contribution to cancer.
• Further investigation into the multifaceted roles of snoRNAs in cancer is warranted.
