Werner and Hutchinson–Gilford progeria syndromes: mechanistic basis of human progeroid diseases

Kudlow, Brian A., Kennedy, Brian K., Monnat, Raymond J.·2007·Nature Reviews Molecular Cell Biology

Abstract

Progeroid syndromes have been the focus of intense research in part because they might provide a window into the pathology of normal ageing. Werner syndrome and Hutchinson-Gilford progeria syndrome are two of the best characterized human progeroid diseases. Mutated genes that are associated with these syndromes have been identified, mouse models of disease have been developed, and molecular studies have implicated decreased cell proliferation and altered DNA-damage responses as common causal mechanisms in the pathogenesis of both diseases.

  • Progerin is a truncated lamin A with a hydrophobic farnesylated C-terminal.

    “The aberrantly processed protein produced is called progerin, a truncated form of lamin A with a hydrophobic farnesylated C-terminal 105–112.”
  • HGPS patients suffer laminopathy due to a sporadic deficiency in proteolytic processing of prelamin A into mature lamin A.

    “Hutchison-Gilford progeria syndrome (HGPS) patients suffer from a variety of laminopathy ailments due to a sporadic deficiency in the proteolytic processing of the precursor form of lamin A into the mature protein.”
  • HGPS and RD are laminopathy-based diseases arising from mutations causing altered processing/maturation of lamin A, not from mutated DNA metabolism genes.

    “Interestingly, HGPS and RD are laminopathy-based diseases; they arise not from mutated DNA metabolism genes but from mutations causing altered processing/maturation of lamin A, an intermediate-filament protein component of the nuclear lamina [6,11-16].”
  • Progerin and FC-prelamin A, the mutant forms of lamin A in HGPS and RD cells, disrupt normal nuclear structure including perinucleolar lamin A/C granules containing the replicative proteins PCNA and polymerase δ.

    “Progerin and FC-prelamin A, the mutant forms of lamin A in HGPS and RD cells, respectively (Figure 1; [6,11-16]), are known to disrupt normal nuclear structure including the perinucleolar lamin A/C granules containing the replicative proteins PCNA and polymerase δ [33].”
  • Changes in chromatin state have been strongly implicated in ageing by progeroid syndromes, which disrupt the nuclear lamina and its associated regulation of heterochromatin structure.

    “Nonetheless, changes in chromatin state have been strongly implicated in ageing by progeroid syndromes, which disrupt the nuclear lamina and its associated regulation of heterochromatin structure142,143.”

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.
