The objective in the current study is to test the hypothesis that nocturnal uterine contractions in preterm women can be suppressed by brief ocular exposure to blue light.The Olcese lab at Florida State University identified a novel interaction between the myometrial melatonin receptors and OT receptors in human myometrial cells (Sharkey et al. 2009), which may ultimately help to resolve certain issues surrounding idiopathic preterm labor. Their results consistently indicate that melatonin at physiological concentration sensitizes human myometrial smooth muscle cells to the contractile effects of OT (Sharkey et al. 2010).
