BACKGROUND/AIMS: High mobility group box 1 (HMGB1) is an important mediator of the inflammatory response. It has been implicated in the pathogenesis of autoimmune diseases, atherosclerosis, and obesity. However, the effects of HMGB1 on diabetic nephropathy remain unclear. Here, we investigated the potential roles and mechanisms of an HMGB1 inhibitor, glycyrrhizic acid (GA), in renal injury with the streptozotocin (STZ)-induced rat model. METHODS: The diabetic rat was generated by intraperitoneal injection of STZ and then treated with the HMGB1 inhibitor GA or saline for 8 weeks...

Protocatechuic acid (PCA), a phenolic compound of anthocyanins, was reported to possess various pharmacologic properties, including anti-oxidant, anti-inflammatory, anti-apoptosis, anti-diabetic and anti-tumor activities. However, the role of PCA in diabetic nephropathy remains elusive. The present study was conducted to evaluate the effects of PCA on extracellular matrix (ECM) accumulation in high glucose (HG)-induced human mesangial cells (MCs) and explore the possible mechanism. Our results demonstrated that PCA obviously inhibited HG-induced proliferation of MCs in a dose-dependent manner...

BACKGROUND & AIM: Complement activation plays a key role in the pathogenesis of IgA nephropathy (IgAN). Several studies have reported an association between complement factor H gene rs6677604 polymorphism and susceptibility to IgAN; however, attempts at validating this relationship had yielded inconsistent results. We performed a systematic review and meta-analysis to clarify the association between rs6677604 and IgAN susceptibility, disease severity and chronic progression. METHODS: A comprehensive database search was performed to identify eligible studies...

Diabetic nephropathy (DN) is a major cause of end-stage renal disease (ESRD). Glycyrrhizic acid (GA) is an effective inhibitor of reactive oxygen species (ROS) production. We investigated the role of GA in the progression of renal injury in DN. Albumin (Alb)/creatinine (crea) levels were significantly lower, and renal histopathology was attenuated in the diabetic db/db mice that were treated with GA (15 mg/kg via intraperitoneal injection) once per day for eight weeks. These changes were associated with significantly lower levels of α-smooth muscle actin (α-SMA) and transforming growth factor β1 (TGF-β1) expression...

The human immunodeficiency virus (HIV) infection can lead to progressive decline in renal function known as HIV-associated nephropathy (HIVAN). Importantly, individuals of African ancestry are more at risk of developing HIVAN than their European descent counterparts. An in-depth search on Google Scholar, Medline and PubMed was conducted using the terms "HIVAN" and "pathology and clinical presentation", in addition to "prevalence and risk factors for HIVAN", with special emphasis on African countries for any articles published between 1990 and 2017...

Glomerulonephritis is one of the most serious manifestations of systemic lupus erythematous (SLE). Because SLE is ≥10 times more common in women, a role for estrogens in disease pathogenesis has long been suspected. Estrogen receptor α (ERα) is highly expressed in renal tissue. We asked whether ERα expression contributes to the development of immune-mediated nephropathies like in lupus nephritis. We tested the overall effects of estrogen receptors on the immune response by immunization with OVA and induction of chronic graft-versus-host disease in female ERα-knockout mice...

Background: Iodinated contrast media (CM) used in angiography and computed tomography (CT) scans is an important cause of acute kidney injury (AKI) in hospitalized patients undergoing surgery. Contrast-induced nephropathy leads to AKI soon after CM administration. The aim of the study was to determine whether the timing of contrast media exposure related to diagnostic imaging during the immediate perioperative period influences the risk of post-operative AKI. Methods: All patients aged 18 years or above who underwent diagnostic imaging within 7 days of non-cardiac surgery between 1 January 2003 and 31 December 2013 in the Tayside region of Scotland, UK were included in the analysis...

C-C motif chemokine ligand 2 (CCL2) is a small cytokine that functions in inflammation and cancer development. Bindarit, a CCL2 inhibitor, is a small anti-inflammatory molecule proven safe by phase II trials in type 2 diabetic nephropathy patients. As cancer-related inflammation is a cause of pain, we investigated whether Bindarit suppresses cancer-related inflammation and pain. We established a bone-cancer mouse model by inoculating cancer cells. After applying Bindarit, we preformed pain sensitivity tests and checked cancer development by X-ray...

Apoptosis of renal tubular epithelial cells is a key feature of the pathogenicity associated with tubulointerstitial fibrosis and other kidney diseases. One factor that regulates important cellular processes like apoptosis and cell proliferation is HRD1, an E3 ubiquitin ligase that acts by promoting ubiquitylation and degradation of its target protein. However, the detailed mechanisms by which HRD1 acts as a regulator of apoptosis in renal tubular epithelial cells have not been established. In our previous liquid chromatography-tandem mass spectrometry (LC-MS/MS) study (Mol Endocrinol...

Cardiac fibrosis with diabetic nephropathy (DN) is one of major diabetic complications. miR-21 and MMP-9 were closely associated with fibrosis diseases. Angiotensin II receptor blockers (ARB) have cardioprotective effects. However, it remains unclear whether miR-21 was involved in the mechanism of cardiac fibrosis with DN by target MMP-9 and ARB ameliorates cardiac fibrosis partly by inhibiting miR-21 expression. In this study, In Situ Hybridization(ISH), RT-PCR, cell transfection, western blotting and laser confocal telescope were used, respectively...
