LINE-1 retrotransposition in human embryonic stem cells.

Abstract:

:LINE-1 elements comprise approximately 17% of human DNA and their mobility continues to impact genome evolution. However, little is known about the types of non-transformed cells that can support LINE-1 retrotransposition. Here, we show that human embryonic stem cells express endogenous LINE-1 elements and can accommodate LINE-1 retrotransposition in vitro. The resultant retrotransposition events can occur into genes and can result in the concomitant deletion of genomic DNA at the target site. Thus, these data suggest that LINE-1 retrotransposition events may occur during early stages of human development.

  • Genetic and cellular defects contributing to benign tumor formation in neurofibromatosis type 1.

    abstract::Neurofibromatosis type 1 (NF1) is a common inherited cancer predisposition syndrome. The NF1 gene product, neurofibromin, is hypothesized to function as a tumor suppressor and nearly all NF1 patients develop benign peripheral nerve tumors. These neurofibromas presumably arise from NF1 inactivation in S100(+)Schwann ce...
