Functional Genetics and Metabolism Laboratory

Dr. Kim’s research program focuses on genetic and metabolic regulation of heart development, function and disease, with emphasis on obesity, diabetes and heart failure.

First, we are interested in the molecular function and mechanism of Iroquois (Irx) transcription factors in the heart, which are not only implicated in organ development, but also in energy homeostasis regulation.

Second, we are investigating metabolism of the heart and its communications with other core metabolic tissues/organs (e.g. adipose tissue and liver).

Using genetically engineered mice as our principal models, we integrate physiology with molecular and systems biology approaches to address the fundamental questions in heart function and diseases.

The laboratory is funded by the Heart and Stroke Foundation of Canada, the Natural Sciences and Engineering Research Council of Canada, the J. P. Bickell Foundation, and the Canada Foundation for Innovation.

Focus 
  1. To understand the function and molecular mechanism of Irx3 in the ventricular conduction system programming in the developing and diseased heart
  2. To investigate transcriptional and non-transcriptional functions of Irx5 in the diseased heart
  3. To understand how the heart maintains its functions during nutritional and metabolic challenges
