Patients with HGPS are healthy at birth, then get growth impairment, such as loss of subcutaneous fat, alopecia, osteoporosis and heart diseases in 1-2years. HGPS is caused by progerin, which is a toxic form of lamin A expressed in most differentiated cells. Here, we discuss current views about the molecular mechanisms, the mouse models and the treatment approaches of HGPS.We summarize the work in this area and provide directions and clues for future studies.展开更多
