Abstract:
Transfer RNAs (tRNAs), traditionally considered to participate in protein translation, were interspersed in the entire genome. Recent studies suggested that dysregulation was observed in not only tRNAs, but also tRNA derivatives generated by the specific cleavage of pre- and mature tRNAs in the progression of cancer. Accumulating evidence had identified that certain tRNAs and tRNA derivatives were involved in proliferation, metastasis and invasiveness of cancer cell, as well as tumor growth and angiogenesis in several malignant human tumors. This paper reviews the importance of the dysregulation of tRNAs and tRNA derivatives during the development of cancer, such as breast cancer, lung cancer, and melanoma, aiming at a better understanding of the tumorigenesis and providing new ideas for the treatment of these cancers.
Insights
Transfer RNAs (tRNAs) and their derivatives are increasingly linked to cancer development. Dysregulation of these molecules plays a role in tumor progression and may offer new therapeutic targets.
Area of Science:

- Oncology
- Genetics
Background:
- Transfer RNAs (tRNAs) are essential for protein translation.
- Recent research indicates tRNA and tRNA-derived fragment dysregulation in cancer progression.
- These molecules are implicated in cancer cell proliferation, metastasis, and angiogenesis.
Purpose of the Study:
- To review the role of tRNA and tRNA derivative dysregulation in cancer development.
- To highlight the involvement of tRNAs in breast cancer, lung cancer, and melanoma.
- To provide insights into tumorigenesis and potential cancer treatment strategies.
Main Methods:
- Literature review of recent studies on tRNAs and cancer.
- Analysis of evidence linking tRNA dysregulation to cancer hallmarks.
- Synthesis of information on tRNA involvement in specific cancer types.
Main Results:
- Dysregulation of tRNAs and their derivatives is a common feature in various cancers.

Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
