Abstract

To explore the protective effect of liraglutide on renal damage in rats with diabetic kidney disease (DKD) through the protein kinase B-mammalian target of rapamycin (Akt-mTOR) pathway. A total of 45 specific pathogen-free male Sprague-Dawley rats were divided into healthy group (no diabetes, n=15), diabetes group (diabetes, n=15), and liraglutide group (diabetes + liraglutide intervention, n=15). The differences in the biochemical indexes, lesion degree, glomerular Nephrin expression level, and mRNA and protein expressions of Akt-mTOR in renal tissues were detected in three groups via hematoxylin-eosin (HE) staining, immunohistochemistry, Western blotting, and quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR), respectively. The albumin-to-creatinine ratio (ACR) and levels of serum creatinine (Scr), urine microalbumin (UmAlb), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) in renal tissues were the lowest in healthy group and the highest in diabetes group, while they significantly declined in liraglutide group compared with those in diabetes group. Also, there were statistically significant differences (p<0...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
