Magnesium isoglycyrrhizinate ameliorates fructose-induced podocyte apoptosis through downregulation of miR-193a to increase WT1.
In this study, we found that MgIG significantly alleviated kidney dysfunction, proteinuria and podocyte injury in fructose-fed rats. It also restored fructose-induced podocyte apoptosis in rat glomeruli and cultured differentiated podocytes. Of note, high-expression of miR-193a, downregulation of Wilms' tumor protein (WT1) and RelA, as well as upregulation of C-Maf inducing protein (C-mip) were observed in these animal and cell models. The data from the transfection of miR-193a mimic, miR-193a inhibitor, WT1 siRNA or LV5-WT1 in cultured differentiated podocytes showed that fructose increased miR-193a to down-regulate WT1, ...

Magnesium isoglycyrrhizinate ameliorates radiation-induced pulmonary fibrosis by inhibiting fibroblast differentiation via the p38MAPK/Akt/Nox4 pathway
Publication date: July 2019Source: Biomedicine & Pharmacotherapy, Volume 115Author(s): Qunfang Yang, Pan Zhang, Tao Liu, Xuan Zhang, Xichun Pan, Yanyan Cen, Ya Liu, Haigang Zhang, Xiaohong ChenAbstractRadiation-induced pulmonary fibrosis (RIPF) is a severe complication in patients treated with thoracic irradiation. Until now, there are no effective therapeutic drugs for RIPF. In the present study, we attempted to evaluate the effect of Magnesium isoglycyrrhizinate (MgIG) on RIPF, and to further explore the underlying mechanisms. We found that MgIG treatment markedly improved radiation-induced lung pathological changes, red...

Magnesium isoglycyrrhizinate ameliorates radiation-induced pulmonary fibrosis by inhibiting fibroblast differentiation via the p38MAPK/Akt/Nox4 pathway.
Abstract Radiation-induced pulmonary fibrosis (RIPF) is a severe complication in patients treated with thoracic irradiation. Until now, there are no effective therapeutic drugs for RIPF. In the present study, we attempted to evaluate the effect of Magnesium isoglycyrrhizinate (MgIG) on RIPF, and to further explore the underlying mechanisms. We found that MgIG treatment markedly improved radiation-induced lung pathological changes, reduced collagen deposition, and decreased the transforming growth factor beta1 (TGF-β1) elevation induced by irradiation. In addition, MgIG treatment significantly relieved oxidative d...

Magnesium lithospermate B protects the endothelium from inflammation-induced dysfunction through activation of Nrf2 pathway.
In this study, we investigated the protective effects of MLB against inflammation-induced endothelial dysfunction in vitro and in vivo, and the underlying mechanisms. Endothelial dysfunction was induced in human dermal microvascular endothelial cells (HMEC-1) in vitro by lipopolysaccharide (LPS, 1 μg/mL). We showed that pretreatment with MLB (10-100 μM) dose-dependently inhibited LPS-induced upregulation of inflammatory cytokines ICAM1, VCAM1, and TNFα, which contributed to reduced leukocytes adhesion and attenuation of endothelial hyperpermeability in HMEC-1 cells. SD rats were injected with LPS (10 mg/kg, ip) to...

Magnesium isoglycyrrhizinate ameliorates liver fibrosis and hepatic stellate cell activation by regulating ferroptosis signaling pathway
Publication date: October 2018Source: Biomedicine & Pharmacotherapy, Volume 106Author(s): Miao Sui, Xiaofei Jiang, Jun Chen, Haiyan Yang, Yan ZhuAbstractFerroptosis is recently reported as a new mode of regulated cell death. It is triggered by disturbed redox homeostasis, overloaded iron and increased lipid peroxidation. Howerver, the role of ferroptosis in hepatic fibrosis remains obscure. In the current study, we attempted to investigate the effect of Magnesium isoglycyrrhizinate (MgIG) on ferroptosis in liver fibrosis, and to further clarify the possible mechanisms. Our data showed that MgIG treatment markedly attenuate...

Effects of Ascorbyl-2-phosphate Magnesium on Human Keratinocyte Toxicity and Pathological Changes by Sorafenib.
Abstract Hand-foot skin reaction is recognized as one of the most common adverse events related to multiple tyrosine kinase inhibitors, but an effective prevention method has not been identified. The chief aim of this study was to find a mechanism-based preventive method for the skin toxicity induced by sorafenib using vitamin C derivatives. The effects of ascorbyl-2-phosphate magnesium (P-VC-Mg) on the molecular and pathological changes induced by sorafenib were investigated in human keratinocyte HaCaT cells. The cell growth inhibition and apoptotic effects of sorafenib were attenuated by P-VC-Mg. Moreover, P-VC-...
