Small Nucleolar RNAs: Insight Into Their Function in Cancer

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• Small nucleolar RNAs (snoRNAs) are non-coding RNAs classified as C/D box or H/ACA box types.
• Canonical functions include 2'-O-ribose methylation (C/D box) and pseudouridylation (H/ACA box) of ribosomal RNAs (rRNAs).
• Growing evidence implicates snoRNAs in diverse cellular processes, both normal and pathological.

Purpose of the Study:

• To review the biogenesis and functions of snoRNAs.
• To explore the association between snoRNAs and various cancer types.
• To discuss the potential of snoRNAs in cancer diagnosis and therapy.

Main Methods:

• Literature review of existing research on snoRNA biogenesis, function, and cancer association.
• Synthesis of data on mutations and aberrant expression of snoRNAs in tumorigenesis.
• Analysis of studies investigating snoRNAs as cancer biomarkers and therapeutic targets.

Main Results:

• SnoRNAs play essential roles beyond rRNA modification, influencing cellular processes.
• Mutations and altered expression of snoRNAs are frequently observed in cancer.
• These findings suggest snoRNAs are involved in cell transformation, tumorigenesis, and metastasis.

Conclusions:

• SnoRNAs are increasingly recognized for their roles in cancer development.
• Further investigation into snoRNA mechanisms is crucial for their application.
• SnoRNAs hold promise as potential biomarkers and therapeutic targets for cancer treatment.
