Can biomarkers predict type 2 diabetic nephropathy

The value of currently available urine biomarkers that identify those at risk for diabetic nephropathy is increasingly called into question. The development of new urine and plasma biomarkers to predict diabetic nephropathy may shed light on disease mechanisms. Also, rational clinical trial design will be made possible by such markers.

Can we develop "humanized mice" for the study of DN?

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.

A role for the study of non-mammalian model systems in DN?

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 »

What is the role of the tubule in early DN?

The primary focus of the pathophysiology of diabetic renal disease has been on the glomerulus. Albuminuria has been shown to be a very sensitive biomarker of proximal tubule injury. Early changes in the proximal tubule may lead to secondary pathology which is typical for diabetic nephropathy. Thus the tubule may represent a therapeutic target for early diabetes.

Demyelination

Demyelination is a prominent feature of clinical neuropathy, but absent from rodent models of diabetes (barring occasional reports of fixation artifact). Some markers of Schwann cell fidelity are disrupted, but myelin remains resplendently unchanged in the face of long periods of excess glucose exposure. Do we have to resort to the usual handwaving of "absoute duration of diabetes" being an explanatory factor when the ...more »
