How this Key Event works
Fat influx to the liver is usually increased under condition like obesity. Free fatty acids (FFA) increase in blood leads to an increase of FFA uptake in the liver. Especially the long chain fatty acids (LCFAs) are translocated across the plasma membrane, reassembled to triglycerides and stored in lipid droplets causing hepatic steatosis .
How it is Measured or Detected
Methods that have been previously reviewed and approved by a recognized authority should be included in the Overview section above. All other methods, including those well established in the published literature, should be described here. Consider the following criteria when describing each method: 1. Is the assay fit for purpose? 2. Is the assay directly or indirectly (i.e. a surrogate) related to a key event relevant to the final adverse effect in question? 3. Is the assay repeatable? 4. Is the assay reproducible?
