Abstract

Shaping the individual brain It is known that LINE-1 (long interspersed element-1) retrotransposons can move throughout the genomes of adult rat neural progenitor cells (NPCs) in vitro and in the mouse brain. Now it is shown that NPCs isolated from human fetal brain and derived from human embryonic stem cells also support the retrotransposition of engineered human LINE-1s in vitro. Interestingly, there is an increase in the copy number of endogenous LINE-1s in the hippocampus and elsewhere in adult human brains when compared to the copy number of endogenous LINE-1s in heart or liver genomic DNA from the same individual. This suggests that LINE-1 retrotransposition events may contribute to individual somatic mosaicism and heterogeneity of gene expression in the brain.
