Translation of the knowledge of the molecular consequences of diabetes to effective therapies requires better measures of disease progression, faithful models of the molecular and cellular pathology, and application of cutting-edge technologies. Validated biomarkers and surrogate end points will allow rapid screening of clinical interventions prior to larger clinical trials, and can assess risk factors and treatment adequacy ...more »
While the mouse has many advantages, the human diabetic nephropathy phenotype has been difficult to faithfully replicate in the mouse using candidate gene approaches. Future work should focus on developing "humanized mice," in which loci associated with human diabetic complications are knock-in to the mouse. These animals could then be used to study mechanisms and therapeutics using systems biology approaches.
Non-mammalian model organisms have been underutilized to understand diabetic nephropathy pathogenesis. These simple model organism systems that permit ease of genetic manipulation, rapid throughput and precise measurement of phenotypes. Work published earlier this year (PNAS 107: 775, 2010) demonstrated that type 2 DM risk loci could be characterized in zebrafish. Interestingly, this study demonstrated this study shows ...more »
