TURKISH JOURNAL OF BIOCHEMISTRY-TURK BIYOKIMYA DERGISI(2020)
Abstract
Background: The proteolytic activities of matrix metalloproteinases (MMP), cell surface enzymes degrading extracellular matrix, is inhibited by matrix metalloproteinase tissue inhibitors (TIMP). We aim to detect the effects of MMP-9 rs3918242 and TIMP-2 rs8179090 gene variations in renal cell cancer transformation. Methods: One hundred tumor and 100 adjacent healthy tissues were obtained from the patients with renal cell cancer. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) was performed and the products carried out in agarose gel electrophoresis were visualized under UV light. Statistical analyses were performed using SPSS 22 and p-values of less than 0.05 were considered as statistically significant. Results: MMP-9 rs3918242 T allele was higher in tumor tissues (36.5%) than adjacent tissues (17%) and odds ratio was found 2.8 in T allele (p<0.001). Odds ratio values were found 3.325 in the carriers of TT genotype and 3.5 in the carriers of CT genotype compared to the carriers of CC genotype (p <0.01). The polymorphism of TIMP-2 rs8179090 was not found statically significant in tumor and adjacent tissues (p> 0.05). Conclusion: MMP-9 rs3918242 T allele, TT and CT genotypes can be used as biomarkers in determining of renal cell carcinoma.
