Effects of the Herbal Product Curcumin on Cardiomyocytes in Micromass Culture and the Potential Role It May Play in Pregnancy and Development.
Curēus 2023 December
Introduction Herbal medicine (HM) consumption during pregnancy has been on the rise in many parts of the world. Curcumin is a proven antioxidant and anti-inflammatory herb component, having demonstrated efficacy in alleviating various diseases. However, there is conflicting evidence with regards to its effect on pregnancy. We assess the safety profile of the main component of turmeric, curcumin, during pregnancy. Furthermore, to investigate curcumin in combination with known teratogen ethanol to identify any protective effect that curcumin might exert. Method Embryonic chick cardiomyocytes in micromass culture were treated with varying concentrations of curcumin. Three endpoints were used to determine the effect of curcumin on these cells: contractile activity (morphological score), cell viability (resazurin assay), and total protein content (kenacid blue assay). Results Curcumin demonstrated cytotoxicity at the highest tested concentrations (10-20μM) by significantly reducing cell activity and total protein. The results of morphological scoring suggest that repeated investigations would have revealed the teratogenic potential of curcumin. Lower concentrations (50nM) of curcumin were comparable to the control. The combination of a non-toxic concentration of curcumin with ethanol revealed additive toxicity. Conclusion It seems unlikely that curcumin will adversely affect the embryo at low doses due to issues of bioavailability. The findings of cytotoxicity and possible teratogenicity at high concentrations are a concern. Due to the limited information available regarding curcumin metabolism in human embryos, advancements in curcumin delivery systems, and the high likelihood of overconsumption, further in vivo research using animal models is required.
