Inhibiting farnesylation of progerin prevents the characteristic nuclear blebbing of Hutchinson-Gilford progeria syndrome.
Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder that is characterized by dramatic premature aging and accelerated cardiovascular disease. HGPS is almost always caused by a de novo point mutation in the lamin A gene (LMNA) that activates a cryptic splice donor site, producing a truncated mutant protein termed "progerin." WT prelamin A is anchored to the nuclear envelope by...
متن کاملHutchinson-Gilford Progeria Syndrome
The Hutchinson-Gilford syndrome or progeria is a laminopathy generated by mutations that affect LMNA gene. This produces an abnormal protein named progerine which alters the formation of the cellular membrane inducing premature aging of all cells. In the present review aspects related to the pathophysiology and clinical characteristics of this syndrome are shown.
متن کاملHutchinson-Gilford Progeria Syndrome
Hutchinson-Gilford Progeria Syndrome (HGPS) is a lethal congenital disorder, characterised by premature appearance of accelerated ageing in children. Although HGPS was first descri‐ bed by Jonathan Hutchinson [1] and then by Hastings Gilford [2] more than a century ago, it was not until 2003 that the genetic basis of HGPS was uncovered [3, 4]. Approximately 90% of HGPS patients have an identica...
متن کاملHutchinson-Gilford progeria syndrome.
Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare, uniformly fatal, segmental "premature aging" disease in which children exhibit phenotypes that may give us insights into the aging process at both the cellular and organismal levels. Initial presentation in early childhood is primarily based on growth and dermatologic findings. Primary morbidity and mortality for children with HG...
متن کاملInhibiting farnesylation reverses the nuclear morphology defect in a HeLa cell model for Hutchinson-Gilford progeria syndrome.
Hutchinson-Gilford progeria syndrome (HGPS) is a devastating premature aging disease resulting from a mutation in the LMNA gene, which encodes nuclear lamins A and C. Lamin A is synthesized as a precursor (prelamin A) with a C-terminal CaaX motif that undergoes farnesylation, endoproteolytic cleavage, and carboxylmethylation. Prelamin A is subsequently internally cleaved by the zinc metalloprot...
