Disease relevance of Long Interspersed Nucleotide Elements

  • We have identified an RNA-dependent DNA polymerase activity in the microsomal fraction of human pluri-potential embryonal carcinoma cells NTera2D1, which are known to express the full length coding strand of the genomic Line-1 (L1) elements [1].
  • Mammalian LINE-1 (L1) elements belong to the superfamily of autonomously replicating retrotransposable elements that lack the long terminal repeated (LTR) sequences typical of retroviruses and retroviral-like retrotransposons [2].
 

High impact information on Long Interspersed Nucleotide Elements

  • We previously isolated two human L1 elements (L1.2 and LRE2) as the progenitors of disease-producing insertions [3].
  • The breakpoint occurs at 9q34 within COL5A1 intron 24 and interestingly, within a LINE-1 (L1) element at Xp21 [4].
  • Glycine receptor beta-subunit gene mutation in spastic mouse associated with LINE-1 element insertion [5].
  • This novel mutation of the dystrophin gene has important implications regarding retrotransposition of an active L1 element and provides a new insight into the origins of mutations in the dystrophin gene [6].
  • In addition, LINE 1 elements, satellite 2 sequences, and CpG island-containing DNA were identified [7].

Gene context of Long Interspersed Nucleotide Elements

  • The spa mutation is an insertion of a LINE-1 element in the gene for the beta subunit of the glycine receptor, Glrb [18].
  • An L1 element disrupts human bone sialoprotein promoter: lack of tissue-specific regulation by distalless5 (Dlx5) and runt homeodomain protein2 (Runx2)/core binding factor a1 (Cbfa1) elements [19].
  • Selection is for the restoration of URA3 gene activity attendant on recombination into an L1 element in the YAC insert [20].
  • A LINE-1 element lies at 5 kb upstream of CYBB in normal persons, and the 5' breakpoint of the deletion in the patient is in the LINE-1 element [21].
  • The truncated L1 element was inserted into CYP51P2 approximately 6 MYR ago [15].
