To systematically review the biological features of tRNA and its modifications, elucidate their mechanistic roles in various cancers, and explore the functions of tRNA-derived small RNAs (tsRNAs) and tRNA-modifying enzymes.
Approach:
Review of tRNA biology: The article reviews the structure, function, and modifications of tRNA, emphasizing their roles in protein synthesis and cellular regulation.
Analysis of cancer mechanisms: It discusses how dysregulation of tRNA expression and modifications contributes to cancer development, influencing tumor proliferation, metastasis, and therapy resistance.
Exploration of tsRNAs: The review highlights the emerging roles of tRNA-derived small RNAs (tsRNAs) in cancer biology, including their potential as biomarkers and therapeutic targets.
Key Findings:
Dysregulated tRNA levels in cancer cells can lead to aberrant protein synthesis and promote tumorigenesis.
tRNA modifications can affect the translation efficiency of oncogenes and tumor suppressor genes.
tsRNAs are linked to cancer hallmarks such as therapy resistance and metastasis.
Interpretation:
The review indicates that tRNA and its modifications are integral to cancer biology, influencing various cellular processes and presenting opportunities for targeted therapeutic strategies.
Limitations:
The review may not cover all recent studies on tRNA and cancer due to the rapidly evolving nature of the field.
Potential biases in the selection of studies and interpretations may exist.
Conclusion:
The insights into tRNA biology and its modifications provide a foundation for advancing precision medicine approaches in oncology.
