Targeting RNA modifications, like N6-methyladenosine, offers new therapeutic strategies. Inhibiting enzymes and reader proteins involved in RNA modification shows promise for treating cancer and enhancing stem cell therapies.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- Cellular enzymes like methyltransferases chemically modify ribonucleotide bases, regulating RNA metabolism.
- Aberrant RNA modification effector proteins are linked to various human diseases, driving therapeutic interest.
Purpose of the Study:
- To review the cellular functions and disease associations of RNA modification regulatory proteins.
- To highlight advances in developing therapeutic agents targeting RNA modification pathways, particularly N6-methyladenosine.
Main Methods:
- Literature review focusing on RNA modification pathways, enzyme functions, and disease links.
- Analysis of early-stage inhibitor development against RNA modification proteins, including METTL3 and YTH reader proteins.
Main Results:
- The N6-methyladenosine pathway is a key focus, with early inhibitor development against reader proteins.
- Limited therapeutic agents currently target the full spectrum of RNA modification writers, readers, and erasers.
Conclusions:
- Targeting RNA modification systems presents a novel therapeutic strategy for cancer treatment and immunotherapy.
- Developing inhibitors for RNA modification pathways holds potential for enhancing stem cell therapies.

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.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
