Non-coding RNAs (ncRNAs) play a critical role in KMT2A-rearranged infant acute lymphoblastic leukemia (ALL). These molecules influence gene expression and epigenetic regulation, offering potential as biomarkers and therapeutic targets.
Area of Science:
- Hematologic Oncology
- Molecular Biology
- Epigenetics
Background:
- KMT2A rearrangements drive aggressive infant acute lymphoblastic leukemia (ALL).
- Non-coding RNAs (ncRNAs) are emerging as key regulators in KMT2A-r ALL.
- ncRNAs influence gene expression, chromatin dynamics, and epigenetic landscapes.
Purpose of the Study:
- To elucidate the multifaceted roles of ncRNAs in KMT2A-r ALL pathogenesis.
- To explore the potential of ncRNAs as biomarkers and therapeutic targets.
Main Methods:
- Review of current literature on ncRNAs in KMT2A-r ALL.
- Analysis of the functional impact of various ncRNA classes (circRNAs, lncRNAs, miRNAs, eRNAs).
Main Results:
- Circular RNAs (circRNAs) contribute to genome instability and chemoresistance.
- Long non-coding RNAs (lncRNAs) maintain leukemic stem cell properties.
- MicroRNAs (miRNAs) and enhancer RNAs (eRNAs) modulate oncogenic networks and gene expression.
Conclusions:
- ncRNAs are integral to KMT2A-r ALL regulatory circuits.
- ncRNAs show promise as biomarkers for classification, risk stratification, and treatment response.
- Targeting ncRNAs presents therapeutic opportunities for precision medicine in high-risk ALL.
