BACKGROUND: The aim of this study was to evaluate the gene polymorphism and expressions of Rho-A, ROCK-1, and ROCK-2 in cholesteatoma.
METHODS: In this study, 120 healthy control group patients and 120 cholesteatoma patients were enrolled. Venous blood was taken from all of the cholesteatoma and control group patients. The genotyping of ROCK-1(G/T)rs35996865, ROCK-2(A/C)rs10178332, and Rho-A(A/T)rs2177268 polymorphisms was performed using predesigned TaqMan SNP Genotyping Assays. Assays-on-Demand SNP genotyping kit was used for the realtime polymerase chain reaction. The expression levels of Rho-A(Hs00357608_m1), ROCK-1(Hs01127699_m1), and ROCK-2(Hs00178154_m1) genes were determined.
RESULTS: The expression of Rho-A, ROCK-1, and ROCK-2 was lower in cholesteatoma patients than in the control group. There was no difference in Rho-AAT/TT and ROCK-1GT/TT variation in cholesteatoma patients compared to the control. However, ROCK-2 AC/CC variance was lower in cholesteatoma patients.
CONCLUSION: The expression of Rho-A, ROCK-1, and ROCK-2 genes may be decreased in cholesteatoma. Furthermore, since ROCK-2 AC/CC genotype is also lower in cholesteatoma, having C allele seems to decrease the risk of developing this disease.
