New study describes a potential drug target for Hutchinson-Gilford progeria syndrome that may aid in the development of more effective treatments. Scientists have identified a potential new treatment approach for Hutchinson-Gilford progeria syndrome HGPS , a progressive genetic disorder that causes rapid and premature aging in children. The findings in mice, published in eLife, show that blocking a protein called ICMT can improve the condition of affected cells without reducing cell division and growth. These results suggest that ICMT could be a useful drug target to treat HGPS, especially as cell division and growth are important for development in children. HGPS is caused by progerin, a mutant protein which undergoes two types of structural modifications called farnesylation and methylation. Progerin accumulates between the membranes that surround the cell nucleus, leading to damage that makes cells slow down their growth and die prematurely.Scientists have identified a potential new treatment approach for Hutchinson-Gilford progeria syndrome HGPSa progressive genetic disorder that causes rapid and premature aging in children.
About Genetics
The findings in mice, published today in eLifeshow that blocking a protein called ICMT can improve the condition of affected cells without reducing cell division and growth. These results suggest that ICMT could be a useful drug target to treat HGPS, especially as cell division and growth are important for Dieorder in children.
HGPS is caused by progerin, a mutant protein which undergoes two types of structural modifications called farnesylation and methylation. Progerin accumulates between the membranes that surround the cell nucleus, leading to damage that makes cells slow down their growth and die prematurely.
Current treatments for HGPS prevent the farnesylation of progerin, but although these drugs improve some symptoms in patients, they can stop cells from multiplying. Cnild experiments have suggested that inactivating the gene for the protein ICMT, which normally causes the methylation of progerin, can also improve key symptoms while avoiding the effects on cell growth and division. However, these benefits have only been demonstrated in HGPS cells outside the body and in mice with a mimic of the disease.

They found that the mice which lacked ICMT survived significantly longer, and had higher body weights, compared to unmodified mice with progeria. They also had larger skeletal muscle fibres, and the muscle cells around their aorta — the large artery in the heart necessary for transporting oxygen-rich blood — resembled those of healthy mice. This result is particularly important as cardiovascular problems are the main cause of mortality in children with HGPS. This treatment delayed the deterioration of the cells and stimulated cell division and growth. Importantly, when applied to healthy human cells and mouse cells that lacked the target ICMT protein, C75 had no significant unintended effects, meaning that it has good specificity for HGPS. Next, the team studied where the progerin protein accumulates in cells treated with C They found that progerin accumulates inside the centre of the cell — the cell nucleus.

This suggests that blocking the methylation of progerin by ICMT redirects the proteins and reduces their ability to cause damage.
