Proliferation And Migration

Morus alba (white mulberry) is native to the northern part of Korea and popularly used as a traditional medicine due to its numerous health benefits against human’s disease. However, the possibility that M. alba may also affect the cardiovascular system remains unexplored. This study sought to investigate the vascular protective effects of the root bark extract of M. alba (MAE). Vascular reactivity was performed in organ baths using isolated rat thoracic aorta, while platelet derived growth factor (PDGF) induced proliferation and migration of vascular smooth muscle cells (VSMCs) were studied by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) and wound healing assay, respectively. MAE evoked a concentration dependent vasorelaxation following endothelium-dependent pathway. However, vessel relaxations in response to MAE were markedly reduced after endothelium removal; treatment of endothelial nitric oxide synthase inhibitor, guanylyl cyclase inhibitor, and nonspecific potassium channel inhibitor, however, was not altered by cyclooxygenase inhibitor. Furthermore, MAE also significantly blunted contractile response to vasoconstrictor agent, phenylephrine. Taken together, the current evidence revealed that MAE is a potent endothelium-dependent vasodilator and this effect was involved in, at least in part, nitric oxide cyclic-guanosine monophosphate (NO-cGMP) pathway in combination with potassium (K+) channel activation. Moreover, MAE inhibited proliferation and migration of VSMCs induced by PDGF. Therefore, MAE could be a promising candidate of natural medicine for preventing and controlling cardiovascular diseases linked with endothelial dysfunction.

Abstract Background Chronic pancreatitis (CP) is a persistent inflammation of the pancreas clinically presented with severe abdominal pain, progressive fibrosis, and loss of exocrine and endocrine functions. Inflammasomes, cytosolic multiprotein complexes which regulate the formation of proinflammatory cytokines, are influenced by various factors including heat shock proteins (HSPs). Morus alba L., or white mulberry root bark is a valued traditional Asian medicine with a diverse array of phytochemicals. The aim of this investigation was to define the modulatory action of methanolic extract of Morus alba root bark (MEMARB) on NLRP3 inflammasome, and HSPs in pancreas subjected to inflammatory insult. Methods Pancreatitis was induced in male albino Wistar rats by ethanol (0–36%) and cerulein (20 µg/kg b.wt., i.p.) for 5 weeks with or without MEMARB administration. Serum lipase/amylase (L/A) ratio, oxidative stress index (OSI) and reduced glutathione (GSH)/oxidized glutathione (GSSG) ratio in the pancreas were evaluated. Levels of serum HSP70 was quantified by ELISA. NF-kappa B, NLRP3-ASC, caspase-1, IL-1β, IL-18, and HSP70 gene expression was quantified by quantitative real-time polymerase chain reaction (qPCR). Results L/A ratio and oxidative stress determined in terms of OSI and GSH/GSSG ratio were elevated in pancreatitis-induced rats. The levels were restored in MEMARB co-administered animals. Serum level of HSP70 was increased in pancreatitis-induced animals and dropped significantly in MEMARB co-administrated rats. Pancreatitis-induced group showed increased expression of NF-kappa B, IL-1β, IL-18, caspase-1, NLRP3-ASC and HSP70 mRNA than in MEMARB treated group. Conclusions It can be concluded that the M. alba root extract modulates the expression of HSP70 and NLRP3-ASC which might be attributed to its pancreato-protective effect.
