Research Interests:

My current research is focused on signaling pathways in the pregnant uterus. I am particularly interested in differences between the normal and preterm uterus (particularly human uterus). This topic is extremely relevant today when 12.8% of births in the United States are premature. Since preterm birth is the leading cause of infant morbidity and mortality, it is distressing that this number is so much higher than in other developed countries.

Title: Integrin Regulation of Stretch-Activated Myometrial Signaling During Pregnancy (8/1/13-7/31/16)
P.I.: Heather Burkin
Description of Project: A better understanding of the signaling pathways that regulate stretch-induced contractility of human myometrium could have important implications for treating preterm labor. Focal Adhesion signaling is activated in term human myometrial tissue in response to stretch, strongly indicating the presence of integrin-matrix binding. This proposal will build on results from the K99 research to identify specific integrins involved in myometrial contractions and focal adhesion signaling. We will determine if loss of beta 1 integrin in the mouse uterine myometrium decreases myometrial contractility in response to stretch in vitro, alters downstream signaling pathways, or results in post-term labor. Finally, the switch from a quiescient myometrial phenotype to a contractile state during pregnancy very likely involves the integration of multiple signaling networks generated from both hormonal and mechanical signals. We will identify and quantitate the global phosphoproteome of pregnant human myometrial cells in response to stretch.

Title: Integrin Regulation of Stretch-Activated Myometrial Signaling During Pregnancy and Labor (8/1/11-7/31/13)
P.I.: Heather Burkin
Description of Project: During pregnancy the onset of labor is dependent on activation of the uterine myometrium from the quiescent to the contractile state. The initiation of uterine contractions requires the activation of both endocrine and stretch‐induced signaling pathways. Because integrins have been shown to play pivotal roles in smooth muscle contractility, I hypothesize at least one integrin heterodimer will be essential to myometrial contractility. This research will determine which integrin subunits are present and/or upregulated in term pregnant human myometrium and if individual integrin subunits regulate stretch‐induced contraction in human uterine tissue. I will also test the hypothesis that enhanced integrin‐ERK activation in the uterus contributes to preterm labor. Defining the integrin‐ mediated signaling pathways that regulate stretch induced activation of the uterine myometrium will have important implications for treating preterm labor.

Teaching

  1. Reproductive Pharmacology Journal Club (CMPP 794), 2012. This one-credit course focused on presenting and critically evaluating recent high profile journal articles. I supervised graduate students as they analyzed and evaluated published papers in the fields of reproductive biology and reproductive pharmacology. Course coordinators: Heather Burkin, Ph.D. and Cherie Singer, Ph.D.
  2. Molecular Pharmacology (PHAR 710) 2011-present. This three-credit course is designed for graduate students earning a Ph.D. and interested in careers in biomedical research and development in academia or industry. The course focuses on the molecular biochemistry of receptor structure, mass action considerations governing ligand-receptor binding interactions, molecular pharmacology of transduction of the receptor signal and specific considerations of receptors as pharmaceutical targets. Over 6 contact hours I cover reproductive hormones, fertility and infertility, pregnancy, hormone replacement therapy, mechanisms of contraceptive action, and environmental endocrine disruptors. Course coordinator: Iain Buxton, Pharm.D.
  3. Ethics in Scientific Research (PHAR 725) 2012-present. This two-credit course explores ethical issues associated with numerous aspects of scientific research. Since ethics represent a system or code of morals defined by a particular person, religion, group, profession, etc., the students in the course comprise a peer group and define through discussion what is considered to be ethical behavior in situations related to scientific research. Case studies are used to provide details related to specific aspects of a variety of research topics and situations. Over 2 contact hours I covered Gene Therapy and Stem Cells in Research and Medicine. I supervised and facilitated an additional 8 contact hours of this course. Course coordinator: Dean J Burkin, Ph.D.
  4. Medical Pharmacology (PHAR 601) 2013. This 9 credit course teaches 2nd year Medical students the principles, mechanisms of action, therapeutic indications, contraindications, side effects and toxic manifestations of pharmacological agents. Over 4 contact hours I cover Endocrine Pharmacology. Course coordinator: Iain Buxton, Pharm.D.
  5. Reproductive Pharmacology (PHAR 770) 2013. Dr. Singer and I have developed this new three-credit course for graduate students earning a Ph.D. and interested in careers in biomedical research and development in academia or industry. This course provides a substantive background in reproductive physiology and explores recent pharmacological developments in reproductive biology. Over 22 contact hours I will cover the hypothalamic/pituitary axis, steroid hormone biosynthesis, regulation, sites and mechanisms of action, spermatogenesis and sperm transport, oogenesis and the menstrual cycle, male and female contraception and infertility, fertilization and implantation, maternal recognition of pregnancy, placentation, gestation, genetic disorders affecting the reproductive system, and hormone replacement therapies. Course coordinators: Heather Burkin, Ph.D. and Cherie Singer, Ph.D.
