Objective. To analyse the expression of 15 genes encoding receptors and enzymes associated with the molecular mechanism of the tocolytic drugs atosiban (oxytocin receptor antagonist), nifedipine (calcium channel blocker) and celecoxib (selective cyclo-oxygenase-2 inhibitor) in preterm labor patients with premature rupture of fetal membranes in relation to symptoms of intrauterine infection and preterm labor risk factors. Design. Experimental molecular study. Setting. Tertiary obstetric care center. Sample. Myometrial samples were obtained during cesarean sections from 35 patients who delivered preterm with unverified symptoms of intrauterine infection, 35 patients who delivered preterm without symptoms of intrauterine infection and 90 women who delivered at term. Methods. The Micro Fluidic Profiling Card analytic system was used to evaluate mRNA expression of the genes of interest. Main outcome measures. The relative quantification values for mRNA expression. Results. The median oxytocin receptor and cyclo-oxygenase-2 mRNA expression in preterm patients with clinical symptoms of intrauterine infection was significantly higher than in preterm patients without symptoms. The median mRNA expression of β1, β3 and β4 subunits of the L-type calcium channel and prostaglandin E2 receptor was significantly higher in preterm patients compared with term patients. Conclusions. The mRNA expression of hormones, enzymes and their receptors associated with tocolytic actions can differ in various clinical conditions. The expression of these genes is regulated at different levels and can be modified by inflammatory factors, which affect their functions. [ABSTRACT FROM AUTHOR] |
