摘要:
Although it can be farnesylated, the mutant lamin A protein expressed in Hutchison Gilford Progeria Syndrome (HGPS) cannot be defarnesylated because the characteristic mutation causes deletion of a cleavage site necessary for binding the protease ZMPSTE24 and effecting defarnesylation. The result is an aberrant farnesylated protein (called “progerin”) that alters normal lamin A function as a dominant negative, as well as assuming its own aberrant function through its association with the nuclear membrane. The retention of farnesylation, and potentially other abnormal properties of progerin and other abnormal lamin gene protein products, produces disease. Farnesyltransferase inhibitors (FTIs) (both direct effectors and indirect inhibitors) will inhibit the formation of progerin, cause a decrease in lamin A protein, and/or an increase prelamin A protein. Decreasing the amount of aberrant protein improves cellular effects caused by and progerin expression. Similarly, treatment with FTIs should improve disease status in progeria and other laminopathies. In addition, elements of atherosclerosis and aging in non-laminopathy individuals will improve after treatment with farnesyltransferase inhibitors.
摘要:
Disclosed herein are point mutations in the LMNA gene that cause HGPS. These mutations activate a cryptic splice site within the LMNA gene, which leads to deletion of part of exon 11 and generation of a mutant Lamin A protein product that is 50 amino acids shorter than the normal protein. In addition to the novel Lamin A variant protein and nucleic acids encoding this variant, methods of using these molecules in detecting biological conditions associated with a LMNA mutation in a subject (e.g., HGPS, arteriosclerosis, and other age-related diseases), methods of treating such conditions, methods of selecting treatments, methods of screening for compounds that influence Lamin A activity, and methods of influencing the expression of LMNA or LMNA variants are also described. Oligonucleotides and other compounds for use in examples of the described methods are also provided, as are protein-specific binding agents, such as antibodies, that bind specifically to at least one epitope of a Lamin A variant protein preferentially compared to wildtype Lamin A, and methods of using such antibodies in diagnosis, treatment, and screening. Also provided are kits for carrying out the methods described herein.
