Abstract:
:Papillary thyroid cancer (PTC) is the most common form of thyroid cancer, comprising 80% of all thyroid malignancies. The phosphoinositide-3-kinase-protein kinase B/Akt (PI3K-PKB/Akt) pathway is a main pathway in control of cell growth. Activated mTOR and Akt are involved in the development and progression of the PTC. This study aimed to evaluate the effects of MTOR (rs2536 and rs2295080) and AKT1 (rs2494732, rs1130214, and rs1130233) polymorphisms on PTC susceptibility. This study was conducted on 131 PTC patients and 144 healthy subjects. Genotype analysis was done using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods. Our results showed no statistically significant association between MTOR rs2536, AKT1 rs2494732, and rs1130214 polymorphisms and PTC development. However, MTOR rs2295080 polymorphism was found to be associated with a decreased risk of PTC in dominant and allelic models. The TT genotype of AKT1 rs1130233 was significantly higher in the PTC group in comparison to the controls, with a 3.5-fold increased risk for developing PTC. Furthermore, the allelic distribution also showed the T allele of rs1130233 as a risk factor for PTC occurrence. In conclusion, our results suggest the MTOR rs2295080 and AkT1 rs1130233 as the protective and risk factors for PTC development, respectively.
