Coenzyme Q10 and lipid-related gene induction in HeLa cells

Am J Obstet Gynecol. 2004 May;190(5):1432-4. doi: 10.1016/j.ajog.2004.01.076.


Objective: Coenzyme Q10 is an antioxidant that may have a therapeutic role in cervical cancer.

Study design: We investigated the cellular and molecular effects of 30 micromol/L Coenzyme Q10 in HeLa cells. Cell growth assays, fluorescence-activated cell sorting analyses, and Oil Red O staining were performed. Microarray experiments were performed in duplicate and analyzed on the basis of 2-fold changes in levels of gene expression.

Results: Coenzyme Q10 inhibited cell growth and led to apoptosis. Microarray analysis showed that 264 sequences were altered over time, with enrichment in lipid-related genes. Enhanced lipid accumulation was confirmed with Oil Red O staining.

Conclusion: A lipid response to Coenzyme Q10 may affect mechanisms of growth inhibition in HeLa cells.
