Summary

Research in my laboratory is focused on understanding the w88 mobile mechanisms that promote uterine contraction and the onset of labor. Preterm birth is the leading cause of neonatal morbidity and mortality in the developed world and the long-term goal is to develop new therapies to promote uterine quiescence and allow a greater proportion of infants to be carried to term. Identification of new pharmacological agents to reduce uterine contraction would reduce preterm birth rates, reduce perinatal health disparities, and improve pregnancy outcomes, all of which have been identified as high priority research problems by the National Institutes of Health. My research has primarily focused on three related projects.

First, we are investigating the role of matrix metalloproteinases (MMPs) in the regulation of uterine contraction and birth timing. This work is currently funded by an NIH R01 award from the Eunice Kennedy Shriver National Institute for Child Health and Human Development. We have shown that expression and activity of MMPs 2 and 9 are elevated in the smooth muscle of the preterm laboring uterus, and that the inhibition of these enzymes reduces contraction in human uterine tissue and delays birth in mice (Ulrich et al., 2019). We are currently working to determine specific mechanisms of MMP9 action in w88 mobile and determine if MMP inhibition prevents preterm delivery in preclinical animal models.

We are also working to understand how mechanical strain causes changes in w88 mobile that precipitate labor. Abnormal uterine distension is associated with cellular stress and increased risk of preterm delivery. We have previously described global changes in phospho-signaling networks that occur in response to mechanical stress on w88 mobile cells (Copley Salem et al., 2018). We are currently working to elucidate how mechanical strain promotes inflammatory signaling, myometrial activation, and increased risk of preterm labor and if specific pathway inhibition can prevent these outcomes. This work has been funded by an R00 award from the NIH The Eunice Kennedy Shriver Institute for Child Health and Human Development and a supplemental research award from the Nevada INBRE.

Finally, we have been funded by Nevada INBRE Developmental Research Project and Women’s Health Supplement Awards to develop a novel 3D bio-printed model of w88 mobile. In the long term, we hope this new model can serve as a homogeneous and widely available tissue source for use in experiments to elucidate important players in contraction and relaxation pathways and for pharmacological studies to identify and test potential new tocolytic drugs.

PRemature Infant

Premature infants often face prolonged hospitalization and increased risk of neonatal mortality, and lifelong health problems.
