      Background: The pathology of diabetic neuropathy involves oxidative stress on pancreatic b-cells, and is related to decreased levels of Insulin-like growth factor 1 (IGF-1). Acylated steryl b-glucoside (PR-ASG) found in pre-germiated brown rice is a bioactive substance exhibiting properties that enhance activity of homocysteine-thiolactonase (HTase), reducing oxidative stress in diabetic neuropathy. The biological importance of PR-ASG in pancreatic b-cells remains unknown.
