Emerging research has suggested that miRNAs play a significant role in oncogenesis and tumor progression by regulating multiple molecular pathways. Here, we investigated miR-300, which inhibited bladder cancer (BCa) migration by regulating the SP1/MMP9 pathway. miR-300, belonging to the DLK1-DIO3 miRNA cluster, is frequently expressed at lower levels in BCa tissue than in adjacent normal tissue due to DNA methylation. Reinforced expression of miR-300 significantly suppressed the migration of BCa cells. We carried out a...

Epsilon-toxin (ETX) is produced by types B and D strains of Clostridium perfringens, which cause fatal enterotoxaemia in sheep, goats and cattle. Previous studies showed that only a restricted number of cell lines are sensitive to ETX and ETX-induced hemolysis has not previously been reported. In this study, the hemolytic ability of ETX was examined using erythrocytes from 10 species including murine, rabbit, sheep, monkey and human. We found that ETX caused hemolysis in human...

Heavy metal ion pollution has become a serious problem. In this paper, a new type of adsorbent, reduced graphene oxide grafted by 4-sulfophenylazo groups (RGOS), was synthesized to adsorb heavy metal ions in an aqueous solution via two kinds of adsorption modes, ion exchange and coordination. The maximum adsorption capacities of the RGOS for Pb(II), Cu(II), Ni(II), Cd(II) and Cr(III) were 689, 59, 66, 267 and 191 mg/g, respectively. Adsorption equilibrium time of RGOS for...

Streptococcus suis is a highly invasive pathogen that can cause sepsis and meningitis in pigs and humans. However, we have limited understanding of the mechanisms S. suis uses to evade innate immunity. To investigate the involvement of the two-component signal transduction system of S. suis in host immune defense, we examined the expression of 15 response regulators of S. suis following stimulation with polymorphonuclear leukocytes (PMNs). We found that several response regulators were significantly up-regulated...

Our previous works have shown that tanshinone IIA inhibited maladaptive extracellular matrix remodeling in cardiac fibroblasts implicating its potential role in treating of pathologic cardiac remodeling. However, the intrinsically poor solubility and bioavailability of tanshinone IIA hindered its clinical application. Here we develop monomethoxy-poly (ethylene glycol)-poly (lactic acid)-D-α-Tocopheryl polyethylene glycol 1000 succinate (mPEG-PLA-TPGS) nanoparticle incorporating tanshinone IIA (tanshinone IIA-NPs) and study its efficacy in post-infarction left ventricular (LV) remodeling. Male C57BL/6 mice underwent left coronary...

Icariin (ICA) is a flavonoid glucoside derived from the Epimedium plant genus, which has potent regenerative properties and is used in western medicine to treat impotence. Recently, ICA has generated great interest in improving hepatic stellate cell function and cardiac rejuvenation. However, how this natural component functions in hematopoiesis remains unexplored. Here we have examined the role of ICA on hematopoietic stem cells (HSCs) using the cancer-prone disease model of Fanconi anemia (FA), an inherited...
