A number of preclinical studies have been done with CoQ10. Research in a laboratory or using animals is done to find out if a drug, procedure, or treatment is likely to be useful in humans. These preclinical studies are done before any testing in humans is begun. Most laboratory studies of CoQ10 have looked at its chemical structure and how it works in the body. The following has been reported from preclinical studies of CoQ10 and cancer:
Animal studies found that CoQ10 boosts the immune system and helps the body fight certain infections and types of cancer.
CoQ10 helped to protect the hearts of study animals that were given the anticancer drug doxorubicin, an anthracycline that can cause damage to the heart muscle.
Laboratory and animal studies have shown that analogs (drugs that are similar to CoQ10) may stop cancer cells from growing.
