Primary Focus

Michelle Baack

Michelle Baack’s research is focused on establishing the under-recognized role of lipid disturbances in the developmental programming of disease. Disease starts long before any symptoms ever develop and is often triggered by genetic and environmental influences.

Although genes are encoded at conception, the environment can alter how genes are expressed (turned off or on). When an environmental stimulus occurs during a critical window of early development to cause life-long changes in the structure and function of the body, this is called developmental programming.

To help improve the long term outcomes of high-risk babies, Dr. Baack’s lab studies how maternal and neonatal nutrition, specifically various types of fats, can increase or decrease the risk of disease, such as obesity, diabetes, dyslipidemia, hypertension, cardiovascular and neurologic consequences.

Behind the research

To meet this objective, the Baack lab research has both a clinical and basic science platforms. Our clinical trials have focused on protecting babies who are born too early. The premature infant is born deficient in omega-3 fatty acids, which are essential for normal health, brain and retinal development. A clinical trial in the Boekelheide NICU focuses on developing new ways to overcome this deficiency with the goal to prevent significant complications of prematurity.

Additionally, Dr. Baack and the research team are working to educate mothers about the importance of a normal intake of omega-3 fats like docosahexaenoic acid (DHA) during breastfeeding. Through the Mother’s Milk DHA study, moms can learn how to assure the breast milk they give their baby is a good source of DHA.

In contrast, Dr. Baack’s basic science research focuses on decreasing fetal exposure to excess “bad” fats (saturated and mono-unsaturated fats) in order to prevent cardiovascular disease even before it begins. Infants born to mothers with diabetes or obesity during the pregnancy are at higher risk of cardiac disease later in life.

Dr. Baack’s lab created a rat model to study how this occurs. We discovered that a diet high in saturated fat, especially alongside diabetic pregnancy, causes excess fat deposition in the developing heart. Moreover, lipid deposition during early development is associated with enlargement of the cardiomyocytes, poor heart function and developmental programming of fuel metabolism, which may increase the risk of heart disease throughout a lifetime.

Dr. Baack and the team are also using this same rat model in collaboration with other labs to understand how maternal diabetes or dyslipidemia may cause abnormal brain, kidney, pancreas and lung vessel development. They hope to raise awareness about the importance of good nutrition and how to balance both “good” and “bad” fats during high-risk pregnancy and early infant development.
