Abstract
This study aimed to study protein expression in diabetic nephropathy (DN) rats and stem cell tissue repair based on nanomembrane concentration technology. Based on the polymer porous self-assembled nanomembrane technology, the content of total protein and albumin in the serum of rats in the control and experimental groups were measured. The obtained images were adopted to analyze the expression of cytoplasmic proteins and membrane proteins, and then the mechanism of stem cell tissue repair function was studied. The results showed that at 56 weeks of age, in contrast to control group, the total protein content in the serum of the experimental group evidently decreased. At 36 weeks of age, the cytoplasmic protein samples of diabetic rats in the experimental group were subjected to three two-dimensional protein electrophoresis. It was found that there were about 701 spots in each gel, and the matching rate was about 87.5%. In contrast to control group, 16 cytoplasmic proteins and 23 membrane proteins of the experimental group changed. The results of the differentially expressed protein analysis indicated that the change trends of protein spots. Based on polymer porous self-assembled nano-film technology, the expression of differential proteins in DN rats was analyzed, which would supplement new research assistance to the mechanism of DN.
