Association between PPAR γ polymorphisms and neurological functional disability of ischemic stroke. J Cereb Blood Flow Metab 2025; 45:328-339. [PMID: 39161254 PMCID: PMC11572223 DOI: 10.1177/0271678x241274681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 04/04/2024] [Accepted: 07/05/2024] [Indexed: 08/21/2024]
Abstract
Peroxisome proliferator-activated receptor-γ (PPARγ) plays a protective role against brain injury after stroke in mice. However, the relationship between PPARγ gene polymorphisms and the functional outcome of acute ischemic stroke (AIS) remains unknown. 8822 patients from The Third China National Stroke Registry (CNSR-III) after whole-genome sequencing, two functional single nucleotide polymorphisms(SNPs) in PPARγ, rs1801282 C > G and rs3856806 C > T, were further analysed. The primary outcome was neurological functional disability at three months. Of the 8822 patients, 968 (11.0%) and 3497 (39.6%) were carriers of rs1801282 and rs3856806, respectively. Carriers of rs3856806 showed reduced risks for three-month neurological functional disability (OR, 0.84; 95% CI, 0.73-0.98; p = 0.02) and reduced risks for higher infarct volume (OR 0.90, 95% CI, 0.81-0.99, p = 0.04). They also had a reduced risk of neurological functional disability only in case of lower baseline IL-6 levels (OR 0.64, 95% CI 0.48-0.84, Pinteraction = 0.01). Carriers of rs1801282 had a reduced risk for three-month neurological functional disability (OR 0.77, 95% CI, 0.61-0.99, p = 0.04). Our study suggested that PPARγ polymorphisms are associated with a reduced risk for neurological functional disability and higher infarct volume in AIS. Therefore, PPARγ can be a potential therapeutic target in AIS.

[PMID: 32772463 DOI: 10.1002/jnr.24709] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 07/08/2020] [Accepted: 07/20/2020] [Indexed: 12/25/2022]
Abstract
Role of peroxisome proliferator-activated receptors (PPARs) in the pathophysiology of stroke and protective effects of PPAR ligands have been widely investigated in the last 20 years. Activation of all three PPAR isoforms, but especially PPAR-γ, was documented to limit postischemic injury in the numerous in vivo, as well as in in vitro studies. PPARs have been demonstrated to act on multiple mechanisms and were shown to activate multiple protective pathways related to inflammation, apoptosis, BBB protection, neurogenesis, and oxidative stress. The aim of this review was to summarize two decades of PPAR research in stroke with emphasis on in vivo animal studies. We focus on each PPAR receptor separately and detail their implication in stroke. This review also discusses recent clinical efforts in the field and the epidemiological data with regard to role of PPAR polymorphisms in susceptibility to stroke, and tries to draw conclusions and describe future perspectives.
