BioAssay: AID 1658

Summary Assay for the inhibition of Hepatic Lipid Droplet Formation

Medical researchers world-wide now use the term "epidemic" or "pandemic" to describe the alarming incidence of obesity in modern society, which is estimated to occur in 30% of the general US population. Perhaps, most alarming is the high incidence of obesity in children and adolescents, which indicates that medical problems associated with obesity (e.g., diabetes, metabolic syndrome, and heart more ..

Medical researchers world-wide now use the term "epidemic" or "pandemic" to describe the alarming incidence of obesity in modern society, which is estimated to occur in 30% of the general US population. Perhaps, most alarming is the high incidence of obesity in children and adolescents, which indicates that medical problems associated with obesity (e.g., diabetes, metabolic syndrome, and heart disease) will increase in the foreseeable future, as obesity often increases with age. The dominant cellular basis for obesity is increased accumulation of triglycerides in lipid droplets within the cell. The two major cell types in which lipid droplet formation leads to pathological problems are adipocytes and hepatocytes.

The overall goal of this project is to identify chemical probes for inhibiting lipid droplet formation in hepatocytes. Identification of such compounds will better our understanding of the biochemical/molecular pathways that lead to the development of fatty liver disease, and may identify lead compounds for consideration for therapeutic development.
