Targeted Chromosomal Cleavage and Mutagenesis in Drosophila Using Zinc-Finger Nucleases

Bibikova, Marina, Golic, Mary, Golic, Kent G, Carroll, Dana·2002·Genetics

Abstract

Zinc-finger nucleases (ZFNs) are hybrids between a nonspecific DNA-cleavage domain and a DNA-binding domain composed of Cys2His2 zinc fingers. Because zinc fingers can be manipulated to recognize a broad range of sequences, these enzymes have the potential to direct cleavage to arbitrarily chosen targets. We have tested this idea by designing a pair of ZFNs that recognize a unique site in the yellow (y) gene of Drosophila. When these nucleases were expressed in developing larvae, they led to somatic mutations specifically in the y gene. These somatic mosaics were observed in approximately one-half of the males expressing both nucleases. Germline y mutations were recovered from 5.7% of males, but from none of the females, tested. DNA sequences were determined and showed that all of the mutations were small deletions and/or insertions located precisely at the designed target. These are exactly the types of alterations expected from nonhomologous end joining (NHEJ) following double-strand cleavage of the target. This approach promises to permit generation of directed mutations in many types of cells and organisms.

  • NHEJ repairs double-stranded breaks without a homologous DNA template, regularly leading to mutations and deletions, and is error-prone.

    “In NHEJ, protein factors re-ligate the broken DNA strand either directly or by including nucleotide insertions or deletions (indels) (Hefferin & Tomkinson, 2005). This process occurs without a homologous DNA template, regularly leading to mutations and deletions in the repaired strand (Bibikova et al., 2002), as shown in Figure 1(A). NHEJ is, therefore, characterized as error-prone.”

  • If nuclease action mutates unintended targets that are important for cellular physiology, the treated cells may become dysfunctional or even die.

    “For example, if the nuclease action mutates unintended targets that are important for cellular physiology, the treated cells may become dysfunctional or even die [61,62,63].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
