Abstract
Backgrounds: Hypertensive nephropathy (HN) is a kind of renal disease caused by essential hypertension that eventually worsens into end-stage renal disease (ESRD). HN could damage the renal tubules, induce kidney damage and renal failure, and increase the risk of stroke, heart disease or death, but there are few ideal drugs for HN treatment.
Methods: In this study, we explored the therapeutic effect of bajijiasu (a compound from Morinda officinalis how and a common traditional Chinese medicine for tonifying the kidney) on the HN rat model. Biochemical analysis, HE staining, and PAS staining were used to assess the effects of bajijiasu on HN rat model. Western blotting was used to analyze the potential mechanisms.
Results: The results of HE staining and PAS staining showed that bajijiasu could alleviate the pathological changes in HN rat models; biochemical analysis found that the concentration of Malondialdehyde (MDA), total protein (TP), albumin (ALB), microalbuminuria (MALB), blood urea nitrogen (BUN), creatinine (Cr), triglyceride (TG), and low-density lipoprotein-cholesterol (LDL-C) were significantly decreased compared with the model group after bajijiasu treatment; and bajijiasu could regulate the expression of TNF-α, IL-6, MDA, SOD1 and AGEs in HN rats; the result of western blotting demonstrated that bajijiasu could down-regulate the expression of TGFβ1, NOX4, JNK, p- JNK and up-regulate the expression PPARγ and SOD 1 in HN rats.
Conclusion: Those results demonstrated that bajijiasu could alleviate the pathological changes and physiological and biochemical symptoms of HN rat models by regulating the expression of TGFβ1, PPARγ, JNK, p-JNK, NOX4 and SOD1 but could not lower the blood pressure of HN rats. Those pieces of evidence may provide a new therapeutic method for HN treatment.
期刊介绍：
Current Molecular Pharmacology aims to publish the latest developments in cellular and molecular pharmacology with a major emphasis on the mechanism of action of novel drugs under development, innovative pharmacological technologies, cell signaling, transduction pathway analysis, genomics, proteomics, and metabonomics applications to drug action. An additional focus will be the way in which normal biological function is illuminated by knowledge of the action of drugs at the cellular and molecular level. The journal publishes full-length/mini reviews, original research articles and thematic issues on molecular pharmacology.
Current Molecular Pharmacology is an essential journal for every scientist who is involved in drug design and discovery, target identification, target validation, preclinical and clinical development of drugs therapeutically useful in human disease.
