Özet
Background. The phosphatidylinositol 3-kinase p85 alpha regulator subunit 1 gene (PIK3R1) encodes the PIK3R1 protein, which plays a direct role in insulin signaling. PIK3R1 (p85 regulatory subunit) connects firmly with the p110 catalytic subunit, and together these proteins form the phosphatidylinositol 3-kinase (PI3K) protein. PI3K is a key protein in the Akt signaling pathway, which regulates cell survival, growth, differentiation, glucose trafficking, and utilization. Defects in the insulin signaling cascade play an important role in the development of insulin resistance, which shares a common genetic basis for metabolic diseases such as type 2 diabetes (T2D), obesity and cardiovascular diseases. Objectives. In our study, we investigated the effect of single nucleotide polymorphisms (SNPs) rs3756668 in 3'UTR region, rs706713 and rs3730089 in exons 1 and 6, respectively, rs7713645 and rs7709243 in intron 1, and rs1550805 in intron 6 of PIK3R1 gene on T2D. Material and methods. This study enrolled a total of 840 individuals, including 427 diabetic individuals (206 obese and 221 non-obese) and 413 nondiabetic individuals (138 obese and 275 non-obese). The target SNPs were analyzed using real-time polymerase chain reaction (RT-PCR). Statistical analysis was performed using SPSS18.0 (IBM Corp., Armonk, USA). The p-values >= 0.05 were consideied statistically significant. Results. The SNPs rs706713 (Tyr73Tyr) and rs3730089 (Met326lle) located in exons, and rS7713645, rs7709243 and rs1550805 located in introns were determined to be significantly associated with T2D and phenotypic features such as obesity, insulin resistance and the lipid parameters. The association with SNP rs3756668, which is located in the 3'UTR, was not significant. Conclusions. Our study supports the role of PIK3R1, an important candidate gene due to its critical role in insulin signal transduction, in T2D development.
