Biography

Dr. Brower received his PhD in Biochemistry and Molecular Biology from the University of Oklahoma Health Sciences Center. As a graduate student he studied the regulation of gene expression in the lab of Joan and Ron Conaway. He then was then a post-doc in Alex Varshavsky's lab in the division of Biology and Biological Engineering at the California Institute of Technology. There he learned genetic engineering.

 

As a scientist at Caltech, Dr. Brower generated a number of genetically modified mouse models to study the role of protein arginylation in cellular protein breakdown. He discovered that the loss of protein arginylation in mice causes a dramatic loss of fat and resistance to diet-induced obesity. He also discovered that arginylation was important for the removal of a number of pathogenic forms of proteins known to be associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Amyotrophic Lateral Sclerosis, and frontal temporal dementia.

 

Dr. Brower is continuing this research at ²ÝÝ®´«Ã½¹ÙÍøÏÂÔØ. His laboratory is currently funded by the National Institutes of Health to examine the role of protein quality control in the toxicity of proteins associated with neurodegeneration.
