A study in mice demonstrated that the circFGD4 is highly expressed in the brain and spinal cord, where it functions as a miRNA sponge to regulate neuronal apoptosis and axon regeneration following spinal cord injury [Li et al. DOI:10.1016/j.neulet.2021.135795]. A study in human traumatic brain injury (TBI) patients identified the circFGD4 as a top up-regulated circular RNA (fold change 21.07) in brain injury tissues compared to adjacent contusion tissues, with its expression validated by qRT-PCR [Li et al. DOI:10.3389/fneur.2022.1086553].
