BACKGROUND/AIM: This study is the first to evaluate the relationship of caspase-9 (CASP-9) gene polymorphism with the risk for primary brain tumor development.
The study group included 43 glioma and 27 meningioma patients and 76 healthy individuals. CASP-9 gene Ex5+32 G>A (rs1052576) polymorphism was analyzed by real-time polymerase chain reaction (RT-PCR).
Individuals with the CASP-9 GG genotype had significantly decreased risk of developing a glioma brain tumor (p=0.024). Additionally, the GA genotype was significantly lower in patients with glioma than the control group (p=0.019). A significantly decreased risk of developing glioma was found in the A allele carrier group (p=0.024). However, there was no statistically significant relationship between CASP-9 polymorphism and brain meningioma (p=0.493).
CASP-9 (rs1052576) mutant A allele seems to be a protective factor for glioma brain tumor. Future studies with a larger sample size will clarify the possible roles of CASP-9 gene in the etiology and progression of primary brain tumors.
背景/目的：本研究首次评估半胱天冬酶-9（CASP-9）基因多态性与原发性脑肿瘤发生风险之间的关系。
研究组包括43例神经胶质瘤患者、27例脑膜瘤患者和76名健康个体。采用实时聚合酶链反应（RT-PCR）分析CASP-9基因Ex5+32 G>A（rs1052576）多态性。
携带CASP-9 GG基因型的个体发生神经胶质瘤脑肿瘤的风险显著降低（p=0.024）。此外，神经胶质瘤患者的GA基因型显著低于对照组（p=0.019）。在A等位基因携带者组中，发生神经胶质瘤的风险显著降低（p=0.024）。然而，CASP-9多态性与脑膜瘤之间无统计学显著关系（p=0.493）。
CASP-9（rs1052576）突变A等位基因似乎是神经胶质瘤脑肿瘤的保护因素。未来更大样本量的研究将阐明CASP-9基因在原发性脑肿瘤病因学和进展中的可能作用。
