Summary
Epitranscriptomic modifications on transfer RNA (tRNA) regulate cancer progression. Targeting tRNA writers like Methyltransferase Like 1 protein (METTL1) offers potential for novel cancer therapies.
Area of Science:
- Cancer Biology
- Molecular Biology
- Epigenetics
Background:
- Epitranscriptomic modifications of transfer RNA (tRNA) are increasingly recognized for their role in cancer.
- These modifications influence translational control, impacting cancer cell progression and malignant transformation.
- Proteins like Methyltransferase Like 1 (METTL1) are key 'writers' of these tRNA modifications.
Purpose of the Study:
- To review the impact of tRNA modifications in tumorigenesis.
- To explore the role of tRNA modifications in cancer drug resistance and metastasis.
- To highlight the therapeutic potential of targeting the tRNA epitranscriptome.
Main Methods:
- Literature review of studies investigating tRNA modifications in various cancer types.
- Analysis of the role of specific tRNA writers, including METTL1.
- Synthesis of findings on tRNA modification impact on cancer progression and drug resistance.
Main Results:
- tRNA modifications are implicated in fundamental processes driving cancer.
- METTL1 and other tRNA writers are frequently studied in multiple cancer types.
- Modulation of the tRNA epitranscriptome influences cancer drug resistance and metastasis.
Conclusions:
- The tRNA epitranscriptome is a critical regulator of cancer cell biology.
- Targeting tRNA modifications presents a promising strategy for developing novel cancer therapies.
- Modulating tRNA epitranscriptomic processes could lead to first-in-class therapeutics for cancer treatment.

Transfer RNA Synthesis
11.9K
One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
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...

mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Translation
14.7K
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.

Tumor Progression
6.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

MicroRNAs
21.2K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

RNA Splicing
56.2K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
