ALDOSE REDUCTASE ENZYME OVEREXPRESSION IN HEK-293 CELLS: POSSIBLE MODEL OF DIABETIC NEPHROPATHY STUDIES?
Diabetic nephropathy is a condition responsible for a worse prognosis for diabetic patients. Its origins are attributed to several cellular pathways, but the polyol pathway and the production of sorbitol and fructose are central pieces. Even though there is a lot of research on cellular impairment pathways, studying the diabetic kidney condition remains a difficult task due to the shortage of experimental models. This study presents a methodology that seeks to conditionally express the gene limiting the polyol pathway. Microscopy analysis confirm the tool's functionality. However, tests to detect changes in genes related to osmotic stress and morphological changes did not detect expected changes. The results obtained are not sufficient to confirm that only the overexpression of the enzyme responsible for sorbitol production causes deleterious effects in an in vitro model and new methodologies can be used to study the lineage developed in other analytes.
