The body’s ability to metabolize lipid is vital in the proper functioning of biochemical and physiological systems. Dr. Suh’s laboratory has been committed to pursue the issues of ‘why,’, ‘what’ and ‘how’ the normal and abnormal lipid metabolisms in neural (retina) and non-neural tissues (testis/sperm) function. Although the retina and testis/sperm are functionally very different organs, they share a commonality with regards to their novel lipids. Particularly, their specific fatty acid containing phospholipids, as well as tissue specific lipids, are the codes that their research is working to unravel.
Nutrition and Degenerative Eye Diseases:
Nutrients can prevent and/or improve retinal diseases such as diabetic retinopathy, macular dystrophy, and computer vision syndrome. More recently, Dr. Suh’s research has looked into translational studies using humans, which are based off her previous research in various animal models (e.g. Fat-1 mice, type-1 diabetic retinopathy rat model, elongation of very long chain fatty acid 4 (elovl4) deficient mice, and neonatal piglets). Through the usage of nutrient intervention with DHA, β-carotene enriched formulation, lutein and DHA enriched eggs, and choline (deficient/sufficient formulation), she studies various dietary aids to help prevent/mitigate eye degeneration.
Nutrition and Male Reproductive Dysfunction:
Lipids may play a critical role in male reproductive systems (spermatogenesis) in obese, diabetic, and alcohol-challenged animal models. Dr. Suh’s lab has found that docosapentaenoic acid (C22:5n-6) deficiency in testis phospholipids is closely related with abnormal testis growth and sperm production in rodent models. Male reproductive health has been decreasing in recent decades. By using various nutrition interventions (n-6 and n-3 fatty acids, zinc, and conjugated linoleic acid) and alcohol, her lab tries to find ways to maintain optimal male reproductive function.
Nutrition and Fetal Alcohol Spectrum Disorder:
In very recent years, Dr. Suh’s research has explored the impact of nutrition on the fetal brain, retina, and reproductive organ development, by assessing their effects after the developing fetus is exposed to alcohol during pregnancy. This study involves both human and animal work, which will ultimately lead to the development of nutritional strategies for preventing or mitigating the severity of fetal alcohol spectrum disorder.
Why is this work important?
Our basic knowledge on the fundamental roles of nutrition in specialized tissue function is quite limited. Thus, Dr. Suh’s overall research goals may facilitate changes to dietary guidelines, which identify the type and balance of nutrients that are beneficial to visual health, male reproductive health, and fetal alcohol spectrum disorders.
What techniques and equipment are used in this laboratory?
- Gas chromatography; Gas chromatography-mass spectrometry
- Ultra-performance liquid chromatography
- Molecular biology assays (RT-qPCR/microarray)
- Biochemical assays (protein/metabolite biomarkers)
- Specific diet formulations for feeding trials
- Various animal models
- Clinical trials
About Dr. Miyoung Suh
Dr. Miyoung Suh is an Associate Professor in the Department of Food and Human Nutritional Sciences at the University of Manitoba. She has also been trained as a Clinical Dietitian, served as the Director of the University Dietetics Program for 6 years, and has served as the Dietitians of Canada Accreditation Surveyor for the Canadian Dietetic Education Programs since 2011. Dr. Suh is a nutrition lead of the Canada Israel International Fetal Alcohol Consortium (CIIFAC), identifying nutritional status of alcohol-consuming pregnant mothers and alcohol-fed animals.
Dr. Suh’s on-going research involves studying the fundamental roles of dietary lipids in brain, retina, and testes/sperm under alcoholic, diabetic and obese conditions.
She has been awarded ‘Scientist of the Year’ by The Korean Federation of Science and Technology Societies, which is given to a Korean scientist working abroad with significant contributions in their area of research. Dr. Suh’s research in lipids and retina photoreceptors was specifically being recognized. Overall, her research outcomes provide a basis for the provision of optimal nutrition and development of diet strategies beneficial to the target clinical as well as the general population.
