Stopping mitochondrial calcium to eliminate leukemia stem cells

Targeting mitochondrial calcium to eradicate leukemia-initiating cells

['FUNDING_R01'] · UNIVERSITY OF COLORADO DENVER · NIH-11146705

This project tests whether blocking calcium uptake into mitochondria can kill leukemia stem cells that resist venetoclax plus azacitidine in people with acute myeloid leukemia.

What this research studies

Researchers are focusing on leukemia-initiating (stem) cells that survive initial treatment with venetoclax and azacitidine and cause relapses. They will study why some of these resistant cells rely on taking up calcium into their mitochondria and will use drugs and genetic approaches in lab models and patient-derived samples to block that process. The team will compare effects on resistant leukemia cells versus normal blood stem cells to find treatments that target cancer while sparing healthy cells. Results will guide development of new therapies to prevent relapse after ven/aza treatment.

Who could benefit from this research

Good fit: People with acute myeloid leukemia who have received venetoclax plus azacitidine and who have resistant disease or are at high risk of relapse are the main candidates, including those able to provide samples for research.

Not a fit: Patients with other types of leukemia, those never treated with venetoclax plus azacitidine, or whose disease does not depend on mitochondrial calcium are less likely to benefit from this work.

Why it matters

Potential benefit: If successful, this could produce therapies that eliminate drug-resistant leukemia stem cells and lower the chance of relapse in AML patients treated with venetoclax plus azacitidine.

How similar studies have performed: Targeting mitochondrial metabolism has shown promising preclinical results in related research, and targeting the mitochondrial calcium uniporter (MCU) is a newer but encouraging approach in lab studies.
