Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent nuclear transcription factors and members of the nuclear receptor superfamily. Of the three PPARs identified to date (PPARγ, PPARβ/δ, and PPARα), PPARγ has been studied the most, in part because of the availability of PPARγ agonists (also known as PPARγ ligands) and its significant effects on the management of several human diseases including type 2 diabetes, metabolic syndrome, cardiovascular disease and cancers. PPARγ is expressed in many tumors including lung cancer, and its function has been linked to the process of lung cancer development, progression and metastasis. Studies performed in gynogenic and xenograft models of lung cancer showed decreased tumor growth and metastasis in animals treated with PPARγ ligands. Furthermore, data are emerging from retrospective clinical studies that suggest a protective role for PPARγ ligands on the incidence of lung cancer. This review summarizes the research being conducted in this area and focuses on the mechanisms and potential therapeutic effects of PPARγ ligands as a novel anti-lung cancer treatment strategy.
过氧化物酶体增殖物激活受体(PPARs)是配体依赖性核转录因子,属于核受体超家族成员。在迄今已鉴定出的三种PPARs(PPARγ、PPARβ/δ和PPARα)中,PPARγ的研究最为深入,部分原因是有PPARγ激动剂(也称为PPARγ配体)可用,且其对包括2型糖尿病、代谢综合征、心血管疾病和癌症在内的多种人类疾病的治疗具有显著作用。PPARγ在包括肺癌在内的许多肿瘤中表达,其功能与肺癌的发生、发展和转移过程有关。在肺癌的孤雌生殖和异种移植模型中进行的研究表明,用PPARγ配体处理的动物肿瘤生长和转移减少。此外,回顾性临床研究的数据表明,PPARγ配体对肺癌发病率具有保护作用。本综述总结了该领域正在进行的研究,并重点关注PPARγ配体作为一种新型抗肺癌治疗策略的作用机制和潜在治疗效果。
