Abstract
For the treatment and prevention of autoinflammatory diseases, it is essential to develop the drug, regulating the innate immune system. Although differentiation-inducing factor (DIF) derivatives, extracted from the cellular slime mold, Dictyostelium discoideum, exhibit immunomodulatory effects, their effects on the regulation of innate immunity in brain are unknown. In this study, we used the human cerebral microvascular endothelial cell line, hCMEC/D3, to investigate the effects of DIF derivatives on the generation of C-X-C motif chemokine (CXCL) 10 and interferon (IFN)-β induced by polyinosinic-polycytidylic acid (poly IC). DIF-3 (1-10 μM), but not DIF-1 and DIF-2, dose-dependently inhibited the biosynthesis of not only CXCL10 but also CXCL16 and C-C motif chemokine 2 induced by poly IC. DIF-3 also strongly decreased IFN-β mRNA expression and protein release from the cells induced by poly IC through the prohibition of p65, a subtype of NF-ĸB, not interferon regulatory transcription factor 3 phosphorylation. In the docking simulation study, we confirmed that DIF-3 had a high affinity to p65. These results suggest that DIF-3 regulates the innate immune system by inhibiting TLR3/IFN-β signaling axis through the NF-ĸB phosphorylation inhibition.

Hard antler extract inhibits invasion and epithelial-mesenchymal transition of triple-negative and Her-2 + breast cancer cells by attenuating nuclear factor-κB signaling.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hard antler extract (HAE) is a traditional Chinese medicine and has potent antitumor, antioxidative, anti-inflammatory, and immunomodulatory activities. Previous studies have demonstrated that HAE can inhibit human prostate cancer metastasis and murine breast cancer proliferation. However, the effect of HAE on human breast cancer cells has not been clarified. AIM OF THE STUDY To investigate the effects and underlying mechanism of HAE on self-renewal of stem-like cells and spontaneous and transforming growth factor (TGF)-β1-enhanced wound healing, invasion and epithelial-mesenchymal transition (EMT) in breast cancer cells. METHODS HAE was prepared from sika deer by sequential enzymatic digestions and the active compounds were determined by HPLC. The effects of HAE on the viability, mammosphere formation, wound healing and invasion of MDA-MB-231 and SK-BR3 cells were determined. The impact of HAE treatment on spontaneous and TGF-β1-promoted EMT and the nuclear factor (NF)-κB signaling in breast cancer cells was examined by quantitative RT-PCR and western blotting. RESULTS Treatment with HAE at varying concentrations did not change the viability of breast cancer cells. However, HAE at 0.25 or 0.5 mg/mL significantly reduced the number and size of formed mammospheres, and inhibited spontaneous and TGF-β1-enhanced wound healing, invasion and EMT in MDA-MB-231 and SK-BR3 cells in a dose-dependent manner. TGF-β1 treatment significantly decreased IκBα expression and increased NF-kBp65 phosphorylation in breast cancer cells, indicating that TGF-β1 enhanced NF-κB signaling. In contrast, HAE treatment attenuated the spontaneous and TGF-β1-enhanced NF-κB signaling in breast cancer cells. CONCLUSION Our data indicated that HAE inhibited the self-renewal of stem-like cells and spontaneous and TGF-β1-enhanced wound healing, invasion and EMT in breast cancer cells by attenuating the NF-κB signaling in vitro.

Methylphenidate clinically oral doses improved brain and heart glutathione redox status and evoked renal and cardiac tissue injury in rats. Biomed Pharmacother 2018; 100:551-63.

Abstract
Methylphenidate (MPH) is a first-line stimulant drug to treat attention deficit hyperactivity disorder (ADHD). Overdiagnosis of ADHD and MPH abuse lead to serious concerns about the possible long-term adverse consequences of MPH in healthy children and adolescents. We aimed to evaluate MPH effects in adolescent male Wistar rats (postnatal day 40) using an oral dose scheme (2 daily MPH doses 5 mg/kg in a 5% sucrose solution, 5 h apart, for 7 days) that mimics the therapeutic doses given to human adolescents. Twenty-four hours after the last MPH administration, rats were sacrificed and brain areas [cerebellum, prefrontal cortex (PFC), hippocampus, and striatum], peripheral organs (liver, heart, and kidneys), and blood were collected for biochemical and histological analysis. MPH treatment did not alter rats' body temperature or weight, neither food or water intake throughout the experiment. The ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) significantly increased in the PFC and hippocampus of MPH-treated rats, meanwhile protein carbonylation remained unchanged in the brain. In the heart, the GSH/GSSG ratio and GSH levels were significantly increased, with decreased GSSG, while histology revealed significant damage, namely interstitial edema, vascular congestion, and presence of a fibrin-like material in the interstitial space. In the kidneys, MPH treatment resulted in extensive necrotic areas with cellular disorganization and cell infiltration, and immunohistochemistry analysis revealed a marked activation of nuclear factor-ĸB. This study showed that clinically relevant oral MPH doses improve the GSH redox status in the brain and heart, but evoke heart and kidney tissue damage to adolescent rats.

Abstract
Kashin-Beck disease (KBD) is a chronic, endemic osteochondropathy. Its etiopathogenesis is still obscure until now. Epidemiological observation has shown that low selenium play a crucial role in the pathogenesis of KBD. Extracellular signal-regulated kinases (ERKs) and C-Jun N-terminal kinase (JNK), members of the mitogen-activated protein kinase (MAPK) superfamily, play an important role in cell proliferation and differentiation. Nuclear factor-ĸB (NF-ĸB), an important signaling mediator for inflammatory and immune responses, is involved in the regulation of osteoclastogenesis. In the present study, we investigated the expression of ERK and JNK signal molecular, as well as nuclear factor-ĸB in the pathogenesis of Kashin-Beck disease, evaluated the effect of selenium on ERK signal pathway. The expression levels of ERK and JNK signal pathway, as well as nuclear factor-ĸB were investigated for 218 patients and 209 controls by immunoblot analysis in whole blood. Evaluated the effect of selenium on ERK signal pathway by Na2SeO3 treatment. The protein levels of pRaf-1, pMek1/2 and pErk1/2 decreased significantly in KBD patients, p-JNK and NF-ĸB increased in KBD patients. Furthermore, Na2SeO3 treatment improved the reduction of proteins in ERK signal pathway. These findings indicated that ERK and JNK signaling pathways, as well as the expression level of NF-κB signaling molecular are important contributor to the pathogenesis of KBD. Selenium stimulates the phosphorylation of the ERK signaling pathway.
