Metabolic reprogramming in childhood acute lymphoblastic leukemia

Area of Science:

• Oncology
• Cellular Metabolism
• Pediatric Hematology

Background:

• Altered cellular metabolism in cancer was observed nearly a century ago.
• Targeting cancer cell metabolism has been a therapeutic strategy for decades.
• Childhood acute lymphoblastic leukemia (cALL) is a significant pediatric malignancy.

Purpose of the Study:

• To review the current understanding of metabolic dysregulation in cALL.
• To explore how metabolic reprogramming occurs at different stages of cALL.
• To highlight novel therapeutic strategies targeting cALL cell metabolism.

Main Methods:

• Literature review of studies on cALL cell metabolism.
• Analysis of metabolic alterations at diagnosis, during chemotherapy, and in relapsed cALL.
• Focus on emerging therapeutic approaches based on metabolic vulnerabilities.

Main Results:

• cALL cells exhibit metabolic reprogramming, including upregulated glycolysis and reliance on anaplerotic sources.
• Activation of the electron transport chain is observed in cALL.
• Metabolic rewiring allows cALL cells to potentially evade therapy, contributing to refractory disease and relapse.

Conclusions:

• Metabolic reprogramming is a key feature of cALL across disease stages.
• Current therapies may be insufficient due to cALL cells' ability to adapt metabolically.
• Targeting metabolic vulnerabilities presents a promising avenue for novel cALL therapies.
