Therapeutic Effect of Agmatine on Neurological Disease: Focus on Ion Channels and Receptors
Neurochemical Research (2019) 44:735–750 https://doi.org/10.1007/s11064-018-02712-1 REVIEW PAPER Therapeutic Effect of Agmatine on Neurological Disease: Focus on Ion Channels and Receptors Sumit Barua1 · Jong Youl Kim1 · Jae Young Kim1 · Jae Hwan Kim4 · Jong Eun Lee1,2,3 Received: 15 October 2018 / Revised: 19 December 2018 / Accepted: 24 December 2018 / Published online: 4 January 2019 © Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract The central nervous system (CNS) is the most injury-prone part of the mammalian body. Any acute or chronic, central or peripheral neurological disorder is related to abnormal biochemical and electrical signals in the brain cells. As a result, ion channels and receptors that are abundant in the nervous system and control the electrical and biochemical environment of the CNS play a vital role in neurological disease. The N-methyl-D-aspartate receptor, 2-amino-3-(5-methyl-3-oxo-1,2-oxazol-4-yl) propanoic acid receptor, kainate receptor, acetylcholine receptor, serotonin receptor, α2-adrenoreceptor, and acid-sensing ion channels are among the major channels and receptors known to be key components of pathophysiological events in the CNS. The primary amine agmatine, a neuromodulator synthesized in the brain by decarboxylation of L-arginine, can regu- late ion channel cascades and receptors that are related to the major CNS disorders. In our previous studies, we established that agmatine was related to the regulation of cell differentiation, nitric oxide synthesis, and murine brain endothelial cell migration, relief of chronic pain, cerebral edema, and apoptotic cell death in experimental CNS disorders. -

Received: 27 March 2013; in revised form: 27 April 2013 / Accepted: 28 April 2013 / Published: 13 May 2013 Abstract: The Trk family of receptors play a wide variety of roles in physiological and disease processes in both neuronal and non-neuronal tissues. Amongst these the TrkB receptor in particular has attracted major attention due to its critical role in signalling for brain derived neurotrophic factor (BDNF), neurotrophin-3 (NT3) and neurotrophin-4 (NT4). TrkB signalling is indispensable for the survival, development and synaptic plasticity of several subtypes of neurons in the nervous system. Substantial evidence has emerged over the last decade about the involvement of aberrant TrkB signalling and its compromise in various neuropsychiatric and degenerative conditions. -

Vitamin D Receptor Promotes Healthy Microbial Metabolites
www.nature.com/scientificreports OPEN Vitamin D receptor promotes healthy microbial metabolites and microbiome Ishita Chatterjee1, Rong Lu1, Yongguo Zhang1, Jilei Zhang1, Yang Dai 2, Yinglin Xia1 ✉ & Jun Sun 1 ✉ Microbiota derived metabolites act as chemical messengers that elicit a profound impact on host physiology. Vitamin D receptor (VDR) is a key genetic factor for shaping the host microbiome. However, it remains unclear how microbial metabolites are altered in the absence of VDR. We investigated metabolites from mice with tissue-specifc deletion of VDR in intestinal epithelial cells or myeloid cells. Conditional VDR deletion severely changed metabolites specifcally produced from carbohydrate, protein, lipid, and bile acid metabolism. Eighty-four out of 765 biochemicals were signifcantly altered due to the Vdr status, and 530 signifcant changes were due to the high-fat diet intervention. The impact of diet was more prominent due to loss of VDR as indicated by the diferences in metabolites generated from energy expenditure, tri-carboxylic acid cycle, tocopherol, polyamine metabolism, and bile acids. The efect of HFD was more pronounced in female mice after VDR deletion. Interestingly, the expression levels of farnesoid X receptor in liver and intestine were signifcantly increased after intestinal epithelial VDR deletion and were further increased by the high-fat diet. Our study highlights the gender diferences, tissue specifcity, and potential gut-liver-microbiome axis mediated by VDR that might trigger downstream metabolic disorders. Metabolites are the language between microbiome and host1. To understand how host factors modulate the microbiome and consequently alter molecular and physiological processes, we need to understand the metabo- lome — the collection of interacting metabolites from the microbiome and host. -

Indeed, because the biological environment is a complex system, the traditional approach – based on knowledge about the chemical structures – cannot fully explain the nature of interactions between drugs and biological targets. Consequently, in this paper, we propose an unsupervised machine learning approach that uses the information we know about drug-target interactions to infer drug properties. -
Role of Amino Acid Metabolism in Angiogenesis T ⁎ Roxana E
Vascular Pharmacology 112 (2019) 17–23 Contents lists available at ScienceDirect Vascular Pharmacology journal homepage: www.elsevier.com/locate/vph Review Role of amino acid metabolism in angiogenesis T ⁎ Roxana E. Oberkersch, Massimo M. Santoro Department of Biology, University of Padua, Italy ABSTRACT The role of endothelial metabolism represents a crucial element governing the formation and the differentiation of blood vessels, termed angiogenesis. Besides glycolysis and fatty acid oxidation, endothelial cells rely on specific amino acids to proliferate, migrate, and survive. In this review we focus on the metabolism of those amino acids and the intermediates that hold an established function within angiogenesis and endothelial pa- thophysiology. We also discuss recent work which provides a rationale for specific amino acid-restricted diets and its beneficial effects on vascular tissues, including extending the life span and preventing the development of a variety of diseases. 1.

Agmatine Improves Spatial Memory

Endogenous agmatine increases after training in the hippocampus, howbeit the effect of exogenous agmatine on memory is not consistent yet. This work was aimed to assess the differential effect of systemic agmatine on spatial memory consolidation and retrieval. Additionally L-NAME was used to assess if nitric oxide is involved in the effect of agmatine. Methods: Male Sprague-Dawley rats (250-350 g) were trained in water maze single training session. After 24 h the memory of animals were examined in a probe trial which was consisted of a trial without platform. To assess the effect of agmatine (40 mg/kg) on memory consolidation it was administered immediately after training and to assess its effect on memory retrieval it was injected 30 min before probe trial. In order to evaluate the involvement of nitric oxide, L-NAME (3 mg/kg) was co-administered with agmatine. Results: Post-training injection (to assess consolidation phase) of agmatine improved the performance of animals in probe test, while its pre-probe administration (to assess retrieval phase) had no effect.
