Defective Lamin A-Rb Signaling in Hutchinson-Gilford Progeria Syndrome and Reversal by Farnesyltransferase Inhibition
Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare premature aging disorder caused by a de novo heterozygous point mutation G608G (GGC>GGT) within exon 11 of LMNA gene encoding A-type nuclear lamins. This mutation elicits an internal deletion of 50 amino acids in the carboxyl-terminus of prelamin A. The truncated protein, progerin, retains a farnesylated cysteine at its carboxyl terminus, a ...
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 کاملIncomplete processing of mutant lamin A in Hutchinson-Gilford progeria leads to nuclear abnormalities, which are reversed by farnesyltransferase inhibition.
Hutchinson-Gilford progeria syndrome (HGPS) is typically caused by mutations in codon 608 (G608G) of the LMNA gene, which activates a cryptic splice site resulting in the in-frame loss of 150 nucleotides from the lamin A message. The deleted region includes a protein cleavage site that normally removes 15 amino acids, including a CAAX box farnesylation site, from the lamin A protein. We investi...
