Anger is probably one of the mostly debated basic emotions, owing to difficulties in detecting its appearance during development, its functional and affective meaning (is it a positive or a negative emotion?), especially in human beings. Behaviors accompanied by anger and rage serve many different purposes and the nuances of aggressive behaviors are often defined by the symbolic and cultural framework and social contexts. Nonetheless, recent advances in neuroscientific and developmental research, as well as clinical psychodynamic investigation, afford a new view on the role of anger in informing and guiding many aspects of human conducts...

Wound healing is one of the major complications of diabetes, and problems with wound healing in diabetics often lead to amputation and even death. AMP-activated protein kinase (AMPK) is a protein involved in intracellular metabolism. Activated AMPK can reduce visceral fat and cholesterol synthesis and even inhibit hepatic gluconeogenesis. Activation of AMPK has been widely used in the treatment of type II diabetes. We applied an AMPK activator (Adenine) to human fibroblasts and to the wounds of streptozotocin-induced diabetic mice...

The contribution of environmental factors to pancreatic islet damage in type 1 diabetes remains poorly understood. In this study, we crossed mice susceptible to type 1 diabetes, where parental male (CD8(+) T cells specific for IGRP206-214; NOD8.3) and female (NOD/ShiLt) mice were randomized to a diet either low or high in AGE content and maintained on this diet throughout pregnancy and lactation. After weaning, NOD8.3(+) female offspring were identified and maintained on the same parental feeding regimen for until day 28 of life...

REVIEW
Marcus Hollenbach
Glyoxalase-I (Glo-I) and glyoxalase-II (Glo-II) comprise the glyoxalase system and are responsible for the detoxification of methylglyoxal (MGO). MGO is formed non-enzymatically as a by-product, mainly in glycolysis, and leads to the formation of advanced glycation endproducts (AGEs). AGEs bind to their receptor, RAGE, and activate intracellular transcription factors, resulting in the production of pro-inflammatory cytokines, oxidative stress, and inflammation. This review will focus on the implication of the Glo-I/AGE/RAGE system in liver injury and hepatocellular carcinoma (HCC)...

BACKGROUND: Neutrophil extracellular traps (NETs) are released when neutrophils encounter infectious pathogens, especially during sepsis. Additionally, NETosis occurs during venous and arterial thrombosis, disseminated intravascular coagulation, and trauma. OBJECTIVE: We tested if hemodynamic forces trigger NETosis during sterile thrombosis. METHODS: NETs were imaged with Sytox-green during microfluidic perfusion of Factor XIIa-inhibited or thrombin-inhibited human whole blood over fibrillar collagen (± tissue factor)...

Chronic arsenic exposure during development is associated with alterations of chemical transmission and demyelination, which result in cognitive deficits and peripheral neuropathies. At cellular level, arsenic toxicity involves increased generation of reactive species that induce severe cellular alterations such as DNA fragmentation, apoptosis and lipid peroxidation. It has been proposed that arsenic-associated neurodegeneration could evolve to Alzheimer disease in later life.1,2 In this study, the effects of chronic exposure to inorganic arsenic (3 ppm by drinking water) in Wistar rats on the production and elimination of Amyloid-β (Aβ) were evaluated...

Blood-brain barrier (BBB) breakdown has been determined to play a critical role in the pathogenesis of Alzheimer's disease (AD). However, the underlying mechanisms of BBB disruption in AD remain unclear. Our previous study suggested that the receptor for advanced glycation end-products (RAGE) functioned as a signal transduction receptor in Aβ1-42-induced damage in endothelial cells. In our present study, we revealed that RAGE-mediated endoplasmic reticulum stress (ERS) is essential for Aβ-induced endothelial cell damage...

Diabetic nephropathy (DN) is one of the major causes of end‑stage renal failure. Grape seed proanthocyanidin extracts (GSPE) are known to act as antioxidants. The current study aimed to determine the effects of GSPE on the streptozotocin (STZ)‑induced diabetic rat model and to explore the underlying mechanism of its action. Wistar rats were induced into a diabetic state by injection of STZ and were treated with 250 mg·kg‑1·day‑1 GSPE for 24 weeks. Kidney samples were collected for observation of renal pathological changes by light microscope (periodic acid‑Schiff staining) and electron microscopy...

We evaluated whether physiological and pre-eclamptic (PE) placentae, characterized by exacerbated inflammation, presented alterations in pro-inflammatory High Mobility Group Box 1 (HMGB1) and its Receptor of Advanced Glycation End products (RAGE) expression. Moreover, we investigated, in physiological placental tissue, the ability of Low Molecular Weight Heparin (LMWH) to modify HMGB1 structural conformation thus inhibiting RAGE binding and HMGB1/RAGE axis inflammatory activity. HMGB1, RAGE, IL-6 and TNFα (HMGB1/RAGE targets) mRNA expression were assessed by Real Time PCR...

Lung cancer is one of the most common causes of death in the world. Rhizoma paridis saponins (RPS) have been found to show inhibition of pulmonary adenoma in previous research. However, the detailed mechanisms of RPS from a holistic view have not been established. In this study, Lewis pulmonary adenoma mice were successfully established to analyze the pathways involved in RPS intervening tumor formation and progression. As a result, RPS inhibited levels of cytokines or receptors such as VEGFD, VEGFR3, RAGE, IL6R, IL17BR, and CXCL16 which were regarded as the initiators induced tumor cell proliferation, adhesion, angiogenesis, and invasion...

Although inflammatory pain is a common clinical condition, its mechanisms are still unclear. Electroacupuncture (EA), a well-known method of pain management, may reduce inflammatory pain by regulating neurons, astrocytes, and inflammatory signaling pathways. Injections of complete Freund's adjuvant (CFA), which can initiate cell-mediated inflammatory pain, resulted in significant hyperalgesia, which was subsequently prevented by EA. In CFA-injected mice, a dramatic increase was observed in the expression of the following proteins in the dorsal root ganglion and spinal cord dorsal horn: the astrocytic marker GFAP, S100B, RAGE, pPKCε, COX-2, pERK, and pNFκB...

Osteoarthritis (OA) is a chronic degenerative disease that leads to joint failure, pain, and disability. Gene regulation is implicated as a driver of the imbalance between the expression of catabolic and anabolic factors that eventually leads to the degeneration of osteoarthritic cartilage. In our model, knee-joint OA was induced in male Wistar rats by intra-articular sodium monoiodoacetate (MIA) injections. Whole-genome microarrays were used to analyse the alterations in gene expression during the time-course of OA development (at 2, 14, and 28 days post-injection) in rat knee joints...

Patients recovering from sepsis have higher rates of CNS morbidities associated with long-lasting impairment of cognitive functions, including neurodegenerative diseases. However, the molecular etiology of these sepsis-induced impairments is unclear. Here, we investigated the role of the receptor for advanced glycation end products (RAGE) in neuroinflammation, neurodegeneration-associated changes, and cognitive dysfunction arising after sepsis recovery. Adult Wistar rats underwent cecal ligation and perforation (CLP), and serum and brain (hippocampus and prefrontal cortex) samples were obtained at days 1, 15, and 30 after the CLP...

The main causes of Alzheimer's disease (AD) have not determined despite extensive researches and many clinical trials, and as yet, no effective treatment has been developed. Fortunately, stem cell transplantation is emerging as potential therapeutic candidate for AD, but the success of stem cell based therapy depends on the survival of transplanted cells. Here, we generated sRAGE secreting mesenchymal stem cells (sRAGE-MSCs) and then injected theses MSCs or control MSCs with amyloid beta 1-42 (Aβ1-42) into the entorhinal cortices of male Sprague Dawley rats...

High levels of the inflammatory molecule S100B protein have been identified in sera from several perinatal inflammatory conditions involving myelin damage and associated with an adverse prognosis or the emergence of sequelea. S100B is essential for oligodendrocyte (OL) differentiation and maturation, but it remains to be established if excessive levels of released S100B upon early brain injury are deleterious in the neurodevelopmental period. Here, we investigated this possibility by evaluating how elevated S100B affects oligodendrogenesis during this period...

Advanced glycation end products (AGE) are central to the development of cardiovascular complications associated with diabetes mellitus. AGE may alter cellular function through cross-linking of cellular proteins or by activating the AGE receptor (RAGE). However, the signalling molecules involved during AGE stimulation in cardiomyocytes remain unclear. Here, we investigated the effects of AGE treatment on intracellular calcium homeostasis of isolated cardiomyocytes and studied the activation of signalling molecules involved in this process...

Advanced glycosylation end products (AGEs) accumulate in diabetic wounds. Interactions between AGEs and their receptor (RAGE) leads to dermatologic problems in diabetes. Macrophage, which plays important roles in wound healing, highly expresses RAGE. Therefore, we investigated whether RAGE-expressing macrophages might be responsible for impaired wound healing on diabetes. We used anti-RAGE antibody applied topically on diabetic wounds. After confirming that wound healing was improved in anti-RAGE antibody group compared with normal mice, our results showed that macrophages appeared insufficient in the early stage and fading away slowly in the later proliferative phase compared with the control group, which was ameliorated in anti-RAGE antibody-applied wounds...

Linguizhugan decoction (LGZG), a notable prescription in Traditional Chinese Medicine, is a classical formula for the treatment of Alzheimer's disease (AD), inflammatory injury and fluid retention. The present study aimed to investigate the neuroprotective effect of LGZG on an amyloid β (Aβ)‑induced AD rat model. Sprague‑Dawley rats were administered with Aβ1‑42 to induce AD and inflammatory responses, and subsequently with LGZG (4.8, 2.4 or 1.2 g/kg), donepezil (2 mg/kg) or distilled water for 30 consecutive days...

Autophagy serves a role in preserving cellular homeostasis. Diabetes mellitus (DM) impairs cardiac autophagy and is associated with an accumulation of cytotoxic proteins that may provoke apoptosis and damage cardiomyocytes. Histone deacetylase (HDAC) inhibitors attenuate cardiac fibrosis and inflammation, and improve cardiomyopathy resulting from DM. However, the effect of HDAC inhibition on autophagy in DM cardiomyopathy has not been investigated. The purpose of the present study was to evaluate whether HDAC inhibition modulates cardiac autophagy and to investigate the potential mechanisms in type 2 DM (T2DM) hearts...
