Progeroid syndromes: probing the molecular basis of aging?
A valid method of studying age related degenerative pathologies is to study human genetic diseases that appear to accelerate many, though not necessarily all, features of the aging process. Such diseases are described as progeroid syndromes because of their possible relevance to many aspects of aging and age related disease. This article describes the recent progress made at the cellular and mo...
متن کاملThe role of DNA damage in laminopathy progeroid syndromes.
Progeroid laminopathies are characterized by the abnormal processing of lamin A, the appearance of misshapen nuclei, and the accumulation and persistence of DNA damage. In the present article, I consider the contribution of defective DNA damage pathways to the pathology of progeroid laminopathies. Defects in DNA repair pathways appear to be caused by a combination of factors. These include abno...
متن کاملHallmarks of progeroid syndromes: lessons from mice and reprogrammed cells
Ageing is a process that inevitably affects most living organisms and involves the accumulation of macromolecular damage, genomic instability and loss of heterochromatin. Together, these alterations lead to a decline in stem cell function and to a reduced capability to regenerate tissue. In recent years, several genetic pathways and biochemical mechanisms that contribute to physiological ageing...
متن کاملFarnesylated lamins, progeroid syndromes and farnesyl transferase inhibitors.
Three mammalian nuclear lamin proteins, lamin B(1), lamin B(2) and the lamin A precursor, prelamin A, undergo canonical farnesylation and processing at CAAX motifs. In the case of prelamin A, there is an additional farnesylation-dependent endoproteolysis, which is defective in two congenital diseases: Hutchinson-Gilford progeria (HGPS) and restrictive dermopathy (RD). These two diseases arise r...
متن کاملCongenital Myasthenic Syndromes – Molecular Bases of Congenital Defects of Proteins at the Neuromuscular Junction
Congenital myasthenic syndromes (CMS) are heterogeneous disorders caused by mutations in molecules expressed at the neuromuscular junction (NMJ) (Fig. 1). Each mutation affects the expression level or the functional properties or both of the mutant molecule. No fewer than 11 defective molecules at the NMJ have been identified to date. The mutant molecules include (i) acetylcholine receptor (ACh...
