Inflammation causes proliferation of intestinal smooth muscle cells (ISMC), which contributes to a thickened intestinal wall, and also to stricture formation in Crohn's disease. Proliferation of ISMC both in vitro and in vivo caused decreased expression of marker proteins, but the underlying cause is unclear. Since epigenetic change is important in other systems, we examined this in cell lines from rat colon at either low passage or after extended growth, using immunocytochemistry, immunoblotting and qPCR to evaluate phenotype...

Jian-Pi-Yi-Shen formula (JPYSF) is a Chinese herbal decoction used for treating chronic kidney disease (CKD) for over 20 years with good efficiency. However, the mechanism lacks solid evidence. In the present study, we tested the hypothesis that JPYSF may retard CKD progression via inhibition of inflammation in 5/6 nephrectomy (5/6 Nx) rat model. The 5/6 Nx rats were randomly divided into 2 groups: 5/6 Nx group and JPYSF group. Sham-operated rats served as control. JPYSF (2.06 g/kg/d) were administrated by gavage to 5/6 Nx rats daily for 6 weeks...

BACKGROUND: Subclinical inflammation induced by persistent exposure to lipopolysaccharide (LPS) is found in some clinical conditions such as obesity or diabetes. This study aimed to investigate the effect of recurrent LPS exposure on inflammatory markers, oxidative stress balance and cardiac and renal fibrosis in male rats. METHODS: Male Wistar rats were divided into control and LPS-treated. LPS (10 mg/kg/week) was injected intraperitoneally. After 4 weeks, left ventricles and kidneys were homogenized and stained with hematoxylin and eosin (H&E) and Masson trichrome for histological examination...

Given the limited efficacy and potential disadvantages of erythropoiesis-stimulating agents (ESAs) in treating anemia of chronic kidney disease (CKD), the development of better alternative therapies has become a priority. The primary purpose of this study is to investigate the effects of Angelica sinensis polysaccharide (ASP) and its underlying mechanism in the treatment of renal anemia. In the present study, we found that ASP could enhance hypoxic induction of EPO in Hep3B cells, with a mechanism that involved the stabilization of HIF-2α protein...

BACKGROUND: Treatment of spinal cord injury is dependent on neuronal survival, appropriate synaptic circuit preservation, and inflammatory environment management. In this sense, mesenchymal stem cell (MSC) therapy is a promising tool that can reduce glial reaction and provide trophic factors to lesioned neurons. METHODS: Lewis adult female rats were submitted to a unilateral ventral funiculus cut at the spinal levels L4, L5, and L6. The animals were divided into the following groups: IA (intramedullary axotomy), IA + DMEM (Dulbecco's modified Eagle's medium), IA + FS (fibrin sealant), IA + MSC (106 cells), and IA + FS + MSC (106 cells)...

Background: Acute kidney injury (AKI) is not as harmless as previously thought since it may lead to chronic kidney disease (CKD). Because most of the time ischemic AKI occurs unexpectedly, it is difficult to prevent its occurrence and there are no specific therapeutic approaches to prevent the AKI to CKD transition. We aimed to determine whether mineralocorticoid receptor blockade (MRB) in the first days after ischemia/reperfusion (IR) can prevent progression to CKD. Methods: Four groups of male Wistar rats were included: sham and three groups of bilateral renal ischemia for 45 min, one without treatment and the other two receiving spironolactone for 5 or 10 days, starting 24 h after IR...

Though the antidiabetic effect of ginsenoside compound K (CK) has been well studied, the effect of CK on diabetic nephropathy (DN) is not clear. Whether CK would have a protective effect against DN and it could exert the protective effect by inhibiting the oxidative stress, NLRP3 inflammasome and NF-κB/p38 signaling pathway were investigated in this study. Here, the HFD (high fat diet)/STZ (streptozotocin)-induced DN mice model was established to assess the CK effect in vivo. Parallel experiments uncovering the molecular mechanism by which CK prevents from DN was performed in rat glomerular mesangial cell line HBZY-1 exposed to high glucose...

Rheumatoid arthritis is a chronic inflammatory joint disease characterized by synovial proliferation and tissue destruction. Pro-inflammatory cytokines like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) play a key role in the disease process and elevate energy expenditure, which further increases the joint pain and stiffness. The present study was undertaken to explore the anti-arthritic potential of fenugreek mucilage in adjuvant induced arthritic rats. In the present study, paw volume was measured on the 7th , 14th and 21st day...

There is little understanding about dietary proteins and their potential contribution to obesity-induced inflammation. This study investigates the effect of 10 weeks of aerobic training and whey protein (WP) supplementation on visceral adipose tissue inflammation in rats fed a high fat diet (HFD). In the first phase, 40 male Wistar rats were randomly divided into two groups: 1- normal diet (n=8), 2- high-fat diet (n=32). After this period-which lasted nine weeks-in the second phase, rats fed a HFD were randomly assigned into four groups: (n=8/group): 1- sedentary, 2- WP, 3- aerobic training, and 4- WP + aerobic training...

Neuroinflammation has a definitive role in neurodegenerative diseases, such as Parkinson's and Alzheimer's disease. In addition to its pathogenic ligands, toll-like receptors (TLRs) can be activated by damaged endogenous molecules that induce inflammatory signalling pathways such as high-mobility group box 1 protein (HMGB1). Using an ex-vivo rat optic nerve (RON) model, we sought to determine the effects of lipopolysaccharides (LPS; TLR4 agonist), zymosan (TLR2 agonist) or HMGB1-with or without TLR2/4 antagonists, on the expression of glial fibrillary acidic protein (GFAP) and nuclear factor kappa B (NF-ҡβ) for signalling pathway and astrocyte reactivity, using double immunohistochemistry; as well as on the modulation of the neurotoxicity...

Cisplatin (CP) and doxorubicin (DX) can cause testicular injury by inducing oxidative/nitrosative stress, inflammation, and apoptosis, Naringenin (NG) has antioxidant, antinitrative, anti-inflammatory, and anti-apoptotic effects. This study investigated the potential ability of NG to block gonadotoxicity induced CP and DX in male rats. The rats received one injection of either CP (10 mg/kg, i.p.) or DX (15 mg/kg, i,p.), and treated with NG (50 mg/kg/day, p.o.) for 10 days beginning 6 days prior to CP and DX administration...

We aimed to investigate in the present work, using metabonomics approaches, the scalability of lung fibrosis-biomarkers, in bleomycin (BLM) model of pulmonary fibrosis in rats. Sixty male wistar rats, weighing 250±10 g, were randomly divided into three groups: a negative control group receiving normal saline treatment (G1 ), an intratracheal BLM instilled group (G2 ) and an aerosol BLM instilled group (G3 ). Rats were investigated at various times after BLM instillation. Metabolic changes observed in different biofluids have been integrated into the results of the histological examination (increase in inflammation, fibrosis score and TGF-β immunosatining) which provide a novel pathway of biomarkers in pulmonary fibrosis...

The present study aimed to investigate the effects of microRNA (miR)‑214 on neuroapoptosis induced by propofol and the possible mechanism of its anti‑apoptotic effects. Initially, it was observed that miR‑214 expression was upregulated in propofol‑induced neuroapoptosis rats. Next, propofol‑treated nerve cells were transfected with miR‑214 mimics. The results revealed that miR‑214 overexpression induced apoptosis, inhibited cell proliferation, inhibited cyclin D1 protein expression, promoted caspase‑3 activity and B‑cell lymphoma 2‑associated X protein expression, and enhanced the levels of inflammation factors in nerve cells treated with propofol...

Inflammation plays an important role in nerve defects caused by intracerebral hemorrhage. Repairing brain damage by inhibiting the macrophage-inducible C-type lectin/spleen tyrosine kinase (Mincle/Syk) signaling pathway is a potential new target for treating cerebral hemorrhage. In this study, we aimed to determine whether acupuncture through Baihui (DU20) to Qubin (GB7) is an effective treatment for intracerebral hemorrhage through the Mincle/Syk signaling pathway. An intracerebral hemorrhage rat model was established by autologous blood infusion into the caudate nucleus...
