Decoding Acute Myeloid Leukemia: A Clinician's Guide to Functional Profiling.

Area of Science:

• Hematology
• Molecular Biology
• Cancer Research

Background:

• Acute myeloid leukemia (AML) is a heterogeneous clonal disorder with significant therapeutic challenges.
• Despite advances, understanding AML's genetic, metabolic, and epigenetic landscape remains complex.
• Aberrant proliferation of precursor cells characterizes AML, necessitating novel diagnostic and therapeutic strategies.

Purpose of the Study:

• To review diverse functional profiling techniques for understanding acute myeloid leukemia (AML) biology.
• To highlight the advantages, limitations, and successes of these methods in AML research.
• To explore the potential of functional profiling in guiding personalized AML treatment and improving patient outcomes.

Main Methods:

• BH3 profiling (BP) assesses mitochondrial apoptotic thresholds.
• Gene expression profiling (GEP) analyzes transcriptomic alterations.
• Proteomics, metabolomics, drug sensitivity/resistance testing (DSRT), and CRISPR/RNAi screens offer functional insights.
• Multi-omics approaches and artificial intelligence integration are advancing precision.

Main Results:

• Functional profiling identifies AML-specific vulnerabilities and biomarkers.
• Techniques reveal drug resistance mechanisms and potential drug repurposing opportunities.
• Studies have linked specific mutations and gene signatures to aggressive AML subtypes.

Conclusions:

• Functional profiling methods provide critical insights into AML heterogeneity and behavior.
• These techniques are instrumental in identifying novel therapeutic targets and predicting treatment response.
• Integrating functional profiling into routine AML care holds promise for improved patient outcomes.
