| Summary: | IVF: Mechanism and correction of increased cancer risk Increased production of ribosomes, the multi-molecular structures inside cells where protein synthesis occurs, is implicated in the enhanced risk of cancer in offspring conceived by in vitro fertilization (IVF), suggesting an approach to reduce this risk. In studies on IVF mouse embryos, Zhiling Li and colleagues at First Affiliated Hospital of Shantou University Medical College in China found that harmful effects of natural oxidizing agents induced overproduction of specific protein components of ribosomes. This increased the embryos’ susceptibility to tumorigenesis through a particular molecular signaling pathway. Exposure to the natural antioxidant chemical epigallocatechin-3-gallate (EGCG) corrected the overproduction and protected the embryos. EGCG, found in green tea, is being widely investigated for its anticancer effects. Exposing embryos to EGCG during IVF might protect the resulting children from increased risk of tumor formation in later life. |
