Non-coding RNAs (ncRNAs) like miRNAs, circRNAs, and lncRNAs are key drivers of therapy resistance in chronic myeloid leukemia (CML). Understanding their dysregulation is crucial for overcoming treatment challenges and finding a cure for CML.
Area of Science:
- Hematology
- Molecular Biology
- Oncology
Background:
- Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm driven by the BCR-ABL1 fusion gene.
- Tyrosine kinase inhibitors (TKIs) have significantly improved CML patient outcomes, but therapy resistance remains a challenge.
- Non-coding RNAs (ncRNAs) are increasingly recognized for their role in cancer development and treatment resistance.
Purpose of the Study:
- To explore the role of aberrantly expressed ncRNAs in CML therapy resistance.
- To discuss the mechanisms by which ncRNAs influence TKI resistance in CML.
- To highlight the potential of targeting ncRNAs for novel CML therapies.
Main Methods:
- Review of current literature on ncRNAs in CML.
- Analysis of dysregulation patterns of microRNAs (miRNAs), circular RNAs (circRNAs), and long non-coding RNAs (lncRNAs) in CML.
- Discussion of ncRNA-mediated mechanisms of TKI resistance.
Main Results:
- ncRNAs, including miRNAs, circRNAs, and lncRNAs, are frequently dysregulated in CML.
- Aberrantly expressed ncRNAs contribute to both BCR-ABL1 dependent and independent TKI resistance.
- Tumor-suppressing ncRNAs are often silenced, while oncogenic ncRNAs are overexpressed in CML.
Conclusions:
- ncRNAs play a significant role in the development and progression of TKI resistance in CML.
- Targeting specific ncRNAs may offer a promising strategy to overcome CML therapy resistance.
- Further research into ncRNA function and regulation is essential for advancing CML treatment.
