Understanding and Targeting Metabolic Vulnerabilities in Acute Myeloid Leukemia: An Updated Comprehensive Review

Area of Science:

• Biochemistry
• Cancer Biology
• Hematology

Background:

• Acute Myeloid Leukemia (AML) exhibits aggressive proliferation and metabolic reprogramming.
• AML cells display altered mitochondrial function, oxidative phosphorylation (OXPHOS), and biosynthetic pathways compared to normal hematopoietic stem cells (HSCs).

Purpose of the Study:

• To review metabolic distinctions between AML cells and normal HSCs.
• To highlight metabolic vulnerabilities in AML cells as potential therapeutic targets.

Main Methods:

• Review of current literature on AML cell metabolism.
• Analysis of metabolic reprogramming in leukemic progression and therapy resistance.

Main Results:

• AML cells show increased mitochondrial biogenesis, reliance on glycolysis and amino acid metabolism.
• Metabolic dependencies sustain leukemic stem cells (LSCs) and contribute to therapy resistance.
• Metabolic inhibitors demonstrate efficacy in disrupting AML cell survival while sparing normal cells.

Conclusions:

• Targeting AML's metabolic vulnerabilities offers a promising therapeutic strategy.
• Metabolic therapies, including inhibitors of glycolysis, amino acid, and lipid metabolism, show potential for overcoming drug resistance.
• Further research into metabolic plasticity and precision medicine is crucial for improving AML treatment outcomes.
