Oxygen-glucose deprivation and reoxygenation on human cerebral organoids alters expression related to lipid metabolism

Ischemic stroke is one of the most common neurological disease. However, the impact of ischemic stroke on human cerebral tissue remains largely unknown; due to a lack of ischemic human brain samples. In this study, we used cerebral organoids derived from human induced pluripotent stem cells to evaluate the effect of oxygen-glucose deprivation/reoxygenation (OGD/R). We identified 15 differentially expressed genes (DEGs); and found that all the DEGs were downregulated. Pathway analysis showed the relationship of vitamin digestion and absorption, fat digestion and absorption, peroxisome proliferator-activated receptor signaling pathway, and complement and coagulation cascades. These findings indicate the mechanisms underlying ischemic injury in human cerebral tissue.
