Hutchinson-Gilford Progeria Syndrome (HGPS), a rare human disease characterized by premature aging, is mainly caused by the abnormal accumulation of progerin, a mutant form of the mammalian nuclear envelope component lamin A. HGPS patients exhibit vascular alterations and die at an average age of 13 years, predominantly from myocardial infarction or stroke. Animal models of HGPS have been a valuable tool in the study of the pathological processes implicated in the origin of this disease and its associated cardiovascular alterations. Some of the molecular mechanisms of HGPS might be relevant to the process of normal aging, since progerin is detected in cells from normal elderly humans. Conversely, processes linked to normal aging, such as the increase in oxidative stress, might be relevant to the pathogenic mechanisms of HGPS. In this review, we discuss recent advances in the understanding of the molecular mechanisms underlying the cardiovascular alterations associated with HGPS, the potential role of oxidative stress, and therapeutic approaches for the treatment of this devastating disease.
哈钦森-吉尔福德早衰综合征(HGPS)是一种罕见的人类疾病,其特征为早衰,主要由早老素的异常积累引起,早老素是哺乳动物核膜成分核纤层蛋白A的一种突变形式。HGPS患者表现出血管改变,平均在13岁时死亡,主要死因是心肌梗死或中风。HGPS动物模型在研究该疾病起源及其相关心血管改变所涉及的病理过程中一直是一种有价值的工具。HGPS的一些分子机制可能与正常衰老过程相关,因为在正常老年人的细胞中可检测到早老素。相反,与正常衰老相关的过程,如氧化应激增加,可能与HGPS的致病机制有关。在这篇综述中,我们讨论了在理解与HGPS相关的心血管改变的分子机制、氧化应激的潜在作用以及治疗这种毁灭性疾病的治疗方法方面的最新进展。
