Summary
RNA modifications, including inosine, 5-methylcytosine, and N6-methyladenosine, are crucial for cancer stem cell fate. Aberrant mRNA modifications drive cancer growth and metastasis, offering new therapeutic targets.
Area of Science:
- Oncology
- Epigenetics
- Molecular Biology
Background:
- Cancer stem cells (CSCs) drive tumor growth, metastasis, and therapy resistance.
- Research has focused on DNA/histone modifications, with limited understanding of RNA modifications in CSC fate.
- Over 170 RNA modifications exist, but only a few mRNA modifications are well-studied.
Purpose of the Study:
- To review recent advances in three key mRNA modifications: inosine, 5-methylcytosine, and N6-methyladenosine.
- To discuss the molecular mechanisms by which these mRNA modifications maintain CSC stemness.
- To highlight the potential of targeting mRNA modifications for novel cancer therapies.
Main Methods:
- Literature review of recent studies on mRNA modifications in cancer.
- Analysis of transcriptome-wide mapping data for aberrant mRNA modification deposition.
- Synthesis of current knowledge on molecular pathways linking mRNA modifications to CSC fate.
Main Results:
- Inosine, 5-methylcytosine, and N6-methyladenosine are essential for CSC fate regulation.
- Aberrant mRNA modification patterns are widespread across various cancers.
- These modifications disrupt gene regulatory networks, promoting uncontrolled cancer cell proliferation.
Conclusions:
- Targeting specific mRNA modifications offers a promising strategy for eradicating CSCs.
- Understanding these RNA modifications is key to developing novel anti-cancer therapeutics.
- Further research into RNA modification mechanisms can illuminate CSC-driven cancer progression.

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

3.6K
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 the pre-miRNA...

6.8K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
