Research published in The FEBS Journal indicates that mitochondrial DNA copy numbers correlate with cancer progression and gene activity related to chemotherapy.
Key facts
- •Mitochondria contain their own DNA, which is essential for cellular energy production.
- •The study found a correlation between mtDNA copy number and the genetic mutation load in cancer cells.
- •High mtDNA copy numbers are linked to the expression of genes that promote tumor survival.
- •Variations in mtDNA copy number are associated with differential gene expression related to chemotherapy response.
- •The research was published in The FEBS Journal in 2026.
A study published in The FEBS Journal has identified a correlation between mitochondrial DNA (mtDNA) copy numbers and the severity of cancer cells. Researchers found that variations in these copy numbers are linked to both the extent of genetic mutations and the expression of genes that influence how tumors grow and respond to chemotherapy.
Mitochondrial function and tumor growth
The research suggests that an increase in mtDNA copy number may act as a compensatory mechanism for impaired mitochondrial function within cancer cells. Higher levels of mtDNA were specifically associated with the expression of genes that support the survival and growth of tumors.
Implications for cancer management
Corresponding author Riddhiman Dhar of the Indian Institute of Technology Kharagpur stated that the findings reveal a close association between mtDNA copy number, cancer progression, and therapy response. These results may facilitate further research into the role of mitochondria in cancer, potentially leading to new management strategies.
