Association of Klotho Gene Polymorphism and Serum Level of α Klotho Protein with Different Tumor Grades, Overall Survival and Cytokine Profile in Glioma Patients

Popis výsledku v původním jazyce

Gliomas are the most common and lethal forms of malignant brain tumors. We attempted to identify the role of the aging-suppressor Klotho gene and Klotho protein in the immunopathogenesis of gliomas. We examined Klotho genetic variants by PCR-RFLP and measured serum Klotho levels using the ELISA method. We found a statistically significantly increased frequency of rs1207568A allele and rs1207568 GA genotypes in co-dominant, dominant and over-dominant models in grade IV as compared to grade II and III glioma patients. The levels of soluble α Klotho (sαKL) were significantly lower in grade III and IV glioma patients than in healthy controls (p = 0.034; 0.0083). Patients with sαKL levels above 2500 pg/mL survived significantly longer than patients with sαKL below 2500 pg/mL (p = 0.038). We also found a positive correlation of the serum levels of sαKL with seven biomarkers, like angiogenic vascular endothelial growth factor (p = 0.0008), chemokine fractalkine (p = 0.0009), interferon γ (p = 0.003), glial derived neurotrophic factor (p = 0.0268), pro-inflammatory and pro-Th1 cytokine IL-6 (p = 0.0347), anti-inflammatory, pro-Th2 cytokines IL-4 (p = 0.0037) and IL-13 (p = 0.0004). Our results suggest the impact of Klotho genetic variants and Klotho levels on advanced-grade glioma.
