Association between PPARs Gene Functional Polymorphisms and Ischemic Stroke in Chinese Uyghur Population

Area of Science:

• Genetics and Molecular Biology
• Cardiovascular Research
• Neurology

Background:

• Peroxisome proliferator-activated receptors (PPARs) regulate inflammation, glucose metabolism, and endothelial function, suggesting a role in ischemic stroke (IS).
• Genetic variations in PPARs may influence IS susceptibility.
• The Uyghur population, with mixed European and East Asian ancestry, offers a unique genetic context for studying IS.

Purpose of the Study:

• To investigate the association between functional polymorphisms of PPARγ and PPARα and ischemic stroke (IS) in the Chinese Uyghur population.
• To determine if specific PPAR gene variants are linked to IS risk in this unique ethnic group.

Main Methods:

• Genotyping of PPARγ Pro12Ala and PPARα polymorphisms in 100 IS patients and 100 healthy controls from the Chinese Uyghur population.
• Statistical analysis to assess allele and genotype frequencies and their association with IS.

Main Results:

• The PPARγ Pro12Ala polymorphism showed a protective effect, with the Ala allele being more frequent in controls (P = 0.008).
• Carriage of the Pro/Ala genotype for PPARγ was associated with a reduced risk of IS (OR 0.542).
• The 162Val allele of PPARα was found to be extremely rare in both IS patients and controls within the Uyghur population.

Conclusions:

• The PPARγ Pro12Ala polymorphism may act as an independent protective factor against ischemic stroke in the Chinese Uyghur population.
• The low frequency of the PPARα 162Val allele highlights ethnic-specific genetic patterns in IS.
