Circulating microRNAs in hematological diseases: principles, challenges, and perspectives

Area of Science:

• Biochemistry
• Molecular Biology
• Genetics

Background:

• MicroRNAs (miRNAs) are crucial regulators of cellular functions, including development, differentiation, and apoptosis.
• Cell-free miRNAs circulating in body fluids have been identified.
• These circulating miRNAs are stable and reflect physiological and pathophysiological states, making them potential disease biomarkers.

Purpose of the Study:

• To review recent findings on miRNA-mediated cell-to-cell communication.
• To discuss the functions of circulating miRNAs in hematology.
• To highlight the potential of circulating miRNAs as biomarkers for disease detection and monitoring.

Main Methods:

• Literature review of recent studies on circulating miRNAs.
• Analysis of miRNA-mediated cell-to-cell communication mechanisms.
• Evaluation of circulating miRNAs in hematological contexts.
• Discussion of strategies for designing biomarker studies involving circulating miRNAs.

Main Results:

• Circulating miRNAs are involved in intercellular communication.
• These molecules play significant roles in hematological processes.
• Their stability and reflective nature make them promising diagnostic and prognostic indicators.
• Current approaches for biomarker study design are discussed.

Conclusions:

• Circulating miRNAs represent a novel class of biomarkers.
• They hold significant potential for both clinical and basic research in various diseases, particularly in hematology.
• Further research into circulating miRNAs can advance disease diagnostics and understanding.
