BACKGROUND Pentoxifylline (PTX) anti-TNF properties are known to exert hepatoprotective effects in various liver injury models. The aim of this study was to investigate whether PTX has beneficial roles in the development of methionine- and choline-deficient-(MCD-) diet-induced NAFLD SD rats in vivo and TNF-α-induced Hep3B cells in vitro. METHODS SD Rats(More)
PURPOSE We investigated the effects of quercetin on fibrotic markers and matrix metalloproteinases (MMPs) in primary cells and whole orbital tissues from Graves' orbitopathy (GO). METHODS Orbital fat tissues were harvested from GO for primary cell and tissue cultures during orbital fat decompression. To determine noncytotoxic dose and time of quercetin(More)
PURPOSE Protocatechuic aldehyde (3,4-dihydroxybenzaldehyde; PCA) is extracted from Salvia miltiorrhiza, and has been reported to possess antiproliferative, antioxidant, and antiadipogenesis properties in various in vivo and in vitro experiments. This study aimed to outline the antioxidant and suppressive effects of PCA on adipogenesis and hyaluronan(More)
PURPOSE To investigate the role of microRNA 146a (miR-146a) in the regulation of inflammation in an in vitro model of Graves' orbitopathy (GO). METHODS The level of miR-146a expression in orbital adipose tissue was compared between GO and non-GO by quantitative real-time PCR (qPCR). The effects of interleukin 1β (IL-1β) on miR-146a expression were(More)
PURPOSE Multiple causative factors complicate the pathogenesis in Graves' orbitopathy (GO). It has been suggested that oxidative stress contributes to the development and progression of GO. Therefore, we investigated the therapeutic effect of resveratrol, a potent antioxidant, upon oxidative stress levels in GO orbital fibroblasts in vitro. METHODS(More)
In the last decade, drug delivery systems using biologically active molecules for cellular uptake of therapeutic targets have been studied for application and testing in clinical trials. For instance, the transactivator of transcription (TAT) peptide, or cell-penetrating peptide, was shown to deliver a variety of cargoes, including proteins, peptides, and(More)
PURPOSE We investigated the therapeutic effect of nontoxic concentrations of tanshinone IIA (TanIIA) from Salvia miltiorrhiza in primary cultures of orbital fibroblasts from Graves' orbitopathy (GO). METHODS The effect of TanIIA on IL-1β-induced proinflammatory cytokine (IL-6, IL-8, MCP-1) expression was determined by real-time PCR. Antioxidant activity(More)
