Cofilin is a actin-binding protein in eukaryotic cells. It plays a role in maintaining the steady state of the internal environment through regulating actin dynamics, which contributes to the development of various kinds of diseases. In recent 20 years, cofilin has been widely attracted due to its regulatory effect on cell phenotype, gene transcription, apoptosis and inflammation in renal tissue. Cofilin plays a regulatory role in pathological changes in proteinuria diseases such as minimal change nephropathy, focal segmental glomerulosclerosis, membranous nephropathy, and IgA nephropathy. It could be one of the diagnosis index for glomerular podocyte injury. At the same time, cofilin plays a key role in maintaining the polarity and function of proximal tubular epithelial cells and it is involved in the regulation of kidney inflammation in a variety of kidney diseases, such as renal ischemia/reperfusion injury, diabetic nephropathy, and hypertensive nephropathy reaction. In addition, cofilin plays an important role in epithelial-to-mesenchymal transition (EMT) of tumor cells and epithelial cells in various tissues, suggesting that cofilin may be involved in the regulation of peritoneal dialysis-related EMT and fibrosis. Cofilin might turn into the new diagnosis and treatment target of kidney diseases.

Acute kidney injury is a serious global health problem and determinant of morbidity and mortality. Recent advancements in the field of stem cell research raise hopes for stem cell-based regenerative approaches to treat acute kidney diseases. In this review, the authors summarized the latest research advances of the adult resident renal progenitor cells (ARPCs) on kidney repair, the role of ARPCs on tubular regeneration after acute kidney injury, the current understanding of the mechanisms related to ARPC activation and modulation, as well as the challenges that remain to be faced.

OBJECTIVETo investigate the effect of hyperglycemia induced by different doses of strepzotozocin (STZ) on the liver, kidneys and eyes in rats.

METHODSFifty SD rats were divided equally into 5 groups to receive intraperitoneal injections with a single dose of STZ (40, 50, or 60 mg/kg), 3 doses of 25 mg/kg STZ (given at the interval of 24 h), or no treatment (blank control). The dynamic change of blood glucose was observed within 72 h after the first injection. Blood glucose was then monitored every 3 days and the general conditions of the rats were recorded. In the 9th week, fasting blood samples were collected for biochemical analysis and the pancreas, kidney, liver, and eye were examined for pathologies.

RESULTSWithin 72 h after STZ injection, blood glucose first slightly increased and then decreased and again increased to maintain a high level. Death occurred in rats receiving injections with 50 and 60 mg/kg STZ on the third day. In the surviving rats in the 4 STZ-injected groups, the success rate of modeling was 70%, 89%, 100%, and 100%, respectively. Blood glucose showed an inverse correlation with the body weight of the rats. Cataract was observed in the 10th week in rats injected with 40 mg/kg STZ and in the 8th week in the other groups. In the 9th week, the rats receiving 40 mg/kg STZ showed normal insulin, C-peptide, urea, UA, Cr, ALT, AST, TP, and ALB levels, but the rats in the other groups all showed variations in these biochemical indices, which corresponded to the pathological findings in the pancreas, kidneys, and liver.

CONCLUSIONSThree STZ doses of 25 mg/kg is optimal and efficient for inducing diabetes in rats with stable hyperglycemia. Both fasting and random blood glucose tests contribute to the evaluation of the complications of diabetes. The eyes are the most sensitive to hyperglycemia, followed by the kidneys and then by the liver.
