| Summary: | Background: The aim of this study was to assess the dependence of advanced oxidation protein products (AOPPs) levels on the genotype of the CLOCK 3111T/C SNP in Caucasian menopausal women with and without insomnia.
Methods and Results: The study involved 105 Caucasian menopausal women volunteers aged between 45 and 60 years. The Pittsburgh Sleep Quality Index, PSQI, Insomnia Severity Index (ISI), and Epworth Sleepiness Scale (ESS) were employed. The study of the CLOCK 3111T/C SNP (rs1801260) was performed by PCR. The blood level of advanced oxidation protein products (AOPPs) was detected by IEMA. Based on the results of a clinical-anamnestic examination, the women were divided into two groups: the main (with insomnia) and the control (without insomnia). Given the small number of women carrying the CC genotype of the CLOCK 3111T/C SNP, the СС carriers and TC carriers were combined into one group as the carriers of the minor 3111C allele.
There were no statistically significant differences in the AOPP levels between carriers of different genotypes (TT genotype and TC+CC genotypes) in controls and patients. A comparative analysis of AOPP levels in the women of the main and control groups showed higher AOPP levels in women with insomnia carrying the TT genotype than in the control of the same genotype (P=0.013).
Conclusion: Insomnia in menopausal women is associated with increased protein oxidation only in carriers of the TT genotype of the CLOCK 3111T/C SNP. |
