This study examined the mechanism of action of amiloride, a urokinase-type plasminogen activator receptor inhibitor, in lowering proteinuria. Podocytes were resuscitated to allow for their proliferation and were observed for morphological changes. In the in vitro experiment, control, lipopolysaccharide, and lipopolysaccharide + amiloride groups were established. The expression of urokinase-type plasminogen activator receptor (uPAR) in podocytes was detected with a flow cytometer and cell motility was detected with the transwell migration assay...

OBJECTIVES: Rutin, a polyphenolic flavonoid, was reported to have beneficial effect on drug induced nephropathy. The present study aimed to introduce 5/6 nephrectomized rat model to further evaluate its renal protective effect. METHODS: Adult Wistar rats were induced to develop chronic renal failure through 5/6 nephrectomy (5/6 Nx). After that, animals were treated orally with saline, rutin at 15 and 45 mg/kg, and losartan (10 mg/kg) daily for 20 weeks; sham-operated animals were also involved as control...

SUMMARY: A 39-year-old woman was diagnosed with Systemic lupus erthymatosus (SLE) in 1993, and initially received 30 mg of prednisolone (PSL) daily as treatment. In 2012, the patient was diagnosed with pregnancy-induced hypertension (PIH) complecated with proteinurea, hypertension and pretibial edema at 24 weeks of gestation. At onset, protein urea was 1.6 g/day and she was given bed rest in the hospital with a protein-restricted and low salt diet, which led to a decrease in protein urea to approximately 1 g/day...

Subunit vaccines are typically poorly immunogenic when administered alone, and require adjuvants for robust responses. Triggering TLRs to boost antigen-specific adaptive immunity is an attractive approach to increase the potency and quality of vaccines. However, recent reports suggest that alterations in TLR expression are associated with the pathogenesis of inflammatory and autoimmune diseases. To compare genetic studies with adjuvant studies, we examined whether stimulation through a TLR agonist induces or increases the autoimmune phenotype of healthy or autoimmune mice...

Mycophenolate mofetil (MMF) has long been used to manage lupus nephritis. Despite research on its long-term efficacy, it is still warranted to conduct further investigation regarding its indications, safety and outcome. This study was intended to evaluate our proposed protocol in maintenance therapy with MMF. Twenty-four lupus nephritis patients were registered prior to their receiving 3-6 month induction therapy with monthly iv pulses of cyclophosphamide (CYC), followed by 24 month maintenance therapy using MMF and steroid...

BACKGROUND: Placental abruption is one of the leading causes of maternal mortality and morbidity. Many causes predispose an expecting mother to placental abruption, such as trauma, previous history, smoking, ethnicity and hypertension. The present study concentrated on maternal hypertension as a cause of abruption. METHODS: All subjects of this comparative study underwent a complete obstetrical clinical workup comprising history, general physical examination, abdominal and pelvic examination, and relevant investigations...

Growth-arrested rat mesangial cells (RMCs) at a G0/G1 interphase stimulated to divide in hyperglycemic medium initiate intracellular hyaluronan synthesis that induces autophagy/cyclin D3-induced formation of a monocyte-adhesive extracellular hyaluronan matrix after completing cell division. This study shows that heparin inhibits the intracellular hyaluronan synthesis and autophagy responses, but at the end of cell division it induces synthesis of a much larger extracellular monocyte-adhesive hyaluronan matrix...

Although the analysis of metallothionein (MT) by radioimmunoassay (RIA) is not a common technique, its use is preferred over other methods since it offers the advantages of sensitivity and specificity. In this paper we present data on the basal levels of MT in rat tissues and physiological fluids of female Sprague-Dawley rats. The mean basal MT concentrations of the following organs and fluids were determined by RIA to be: liver (9.8 μg/g), kidney (68 μ/g), brain (0.8 μg/g), spleen (1.0 μg/g), heart (5...

Glomerulosclerosis of any cause is characterized by loss of functional glomerular cells and deposition of excessive amounts of interstitial collagens including collagen I. We have previously reported that mesangial cell attachment to collagen I leads to upregulation of Hic-5 in vitro, which mediates mesangial cell apoptosis. Furthermore, glomerular Hic-5 expression was increased during the progression of experimental glomerulosclerosis. We hypothesized that reducing collagen I accumulation in glomerulosclerosis would in turn lower Hic-5 expression, reducing mesangial cell apoptosis, and thus maintaining glomerular integrity...

BACKGROUND: Cilnidipine (Cil) is an L/N-type calcium channel blocker (CCB) that is known to provide renal protection by decreasing the activity of the sympathetic nervous system and the renin-angiotensin system (RAS). However, very few studies have evaluated the renoprotective effects of Cil in hypertension complicated by diabetes mellitus. In this study, we compared the effects of cilnidipine and the L-type CCB, amlodipine (Aml), in combination with an angiotensin II receptor blocker (ARB) on diabetic nephropathy that developed as a result of inducing diabetes in hypertensive rats...

We previously isolated a novel tyrosine kinase receptor, Flt-1, now known as VEGF-receptor (VEGFR)-1. The VEGF-VEGFR system plays a pivotal role in not only physiological but also pathological angiogenesis. We examined the role of Flt-1 in carcinogenesis using Flt-1-signal-deficient (Flt-1 TK-/-) mice, and found that this receptor stimulates tumor growth and metastasis most likely via macrophages, making it an important potential target in the treatment of cancer. In addition to the full-length receptor, the Flt-1 gene produces a soluble protein, sFlt-1, an endogenous VEGF-inhibitor...
