Hutchinson-Gilford Progeria syndrome (HGPS) serves as a prominent model for Progeroid syndromes, a group of rare genetic disorders characterized by accelerated aging. This review explores the genetic basis, clinical presentation, and complications of HGPS. HGPS is caused by mutations in the LMNA gene, resulting in the production of a defective structural protein, prelamin A. This protein contains a "CAAX" motif, where C represents cysteine, and its abnormal processing is central to the disease's pathology. HGPS leads to multiple organ systems being affected, including cardiovascular, skeletal, neurological, and dermatological systems, causing severe disability and increased mortality. Cardiovascular issues are particularly significant in HGPS and are crucial for developing therapeutic strategies. Recent advances in treatment modalities offer promise for managing HGPS. Farnesyltransferase inhibitors and genetic interventions, such as CRISPR-Cas9, have shown potential in mitigating progerin-associated symptoms, with encouraging results observed in preclinical and clinical studies. Additionally, emerging therapies such as rapamycin, sulforaphane, and MG132 hold promise in targeting underlying disease mechanisms. Comprehensive management approaches, including growth hormone therapy, retinoids, and dental care, are emphasized to enhance overall patient well-being. Despite progress, further research is essential to unravel the complex pathophysiology of Progeroid syndromes and develop effective treatments. Continued focus on therapies that address progerin accumulation and its downstream effects is vital for improving patient care and outcomes for individuals affected by HGPS and related disorders. This review highlights ongoing efforts to understand and combat Progeroid syndromes, aiming to alleviate the burdens imposed by these debilitating conditions.
哈钦森 - 吉尔福德早衰综合征(HGPS)是早老综合征的一个重要模型,早老综合征是一组罕见的遗传性疾病,其特征为加速衰老。本综述探讨了HGPS的遗传基础、临床表现和并发症。HGPS由LMNA基因突变引起,导致产生一种有缺陷的结构蛋白——前体核纤层蛋白A。该蛋白含有一个“CAAX”基序,其中C代表半胱氨酸,其异常加工是该疾病病理的核心。HGPS导致多个器官系统受到影响,包括心血管、骨骼、神经和皮肤系统,造成严重残疾并增加死亡率。心血管问题在HGPS中尤为显著,对制定治疗策略至关重要。治疗方式的最新进展为管理HGPS带来了希望。法尼基转移酶抑制剂和基因干预措施,如CRISPR - Cas9,已显示出减轻早老素相关症状的潜力,在临床前和临床研究中观察到了令人鼓舞的结果。此外,雷帕霉素、萝卜硫素和MG132等新兴疗法有望针对潜在的疾病机制。强调了包括生长激素治疗、维甲酸和牙科护理在内的综合管理方法,以提高患者的整体健康水平。尽管取得了进展,但进一步的研究对于揭示早老综合征的复杂病理生理学和开发有效的治疗方法至关重要。持续关注解决早老素积累及其下游效应的疗法对于改善受HGPS和相关疾病影响的个体的患者护理和预后至关重要。本综述强调了为理解和对抗早老综合征所做的持续努力,旨在减轻这些使人衰弱的疾病所带来的负担。
