Benjamin I Brown
Context • Diet-induced, metabolic endotoxemia is emerging as an important contributory factor to the development of a wide range of chronic diseases, including cardiometabolic, autoimmune, psychiatric, and neurodegenerative illnesses. Emerging human clinical studies have demonstrated that diet and dietary components are potent modifiers of circulating endotoxins and can be used to reduce plasma levels significantly and improve metabolic health. Objective • The aim of the current study was to explore briefly the concept of metabolic endotoxemia and its relationship to disease development, to examine the influence of diet and dietary components on circulating endotoxins, and, finally, discuss the clinical relevance of nutritional interventions for management of metabolic endotoxemia...

Berberine, an isoquinoline alkaloid, has been reported to ameliorate various autoimmune diseases including rheumatoid arthritis by oral administration. However, its mechanism remains mysterious due to an extremely low bioavailability. The fact that berberine is easy to accumulate in gut, the largest endocrine organ in the body, attracts us to explore its anti-arthritic mechanism in view of the induction of intestinal immunosuppressive neuropeptides. In this study, berberine (200 mg/kg, i.g.) was shown to ameliorate collagen-induced arthritis in rats, which was manifested by the reduction of clinical signs and joint destruction, as well as marked down-regulation of Th17 cell frequency and IL-17 level in blood...

Background: Memory-impairment was one of the common characteristics in patients with diabetes mellitus. The release of chronic inflammation mediators and insulin resistance in diabetic brain gave rise to the generation of toxic factor Aβ42 which was the marker of Alzheimer's disease. In addition, the impairment of memory in diabetes mellitus was also correlated predominantly with uptake/metabolism of glucose in medial prefrontal cortex (mPFC). Previously, anti-inflammation and hypoglycemic effects of berberine (BBr) have been described in peripheral tissues...

Xiang-Fu-Si-Wu Decoction (XFSWD) has been used to treat gynecology diseases in clinical practice for hundreds of years in China, especially for primary dysmenorrheal of QiZhi Type. In previous researches, both essential oils (XEO) and non-volatile components (NXEO) extracted from XFSWD showed significant pharmacological activities, but the influence of XEO on NXEO was unclear. The purpose of this paper was to develop a validated analytical method for simultaneous determination of ten components including Vanillic acid, Ferulic acid, Caffeic acid, Gallic acid, Paeoniflorin, Albiflorin, Tetrahydropalmatine, Protopine, Berberine and Tetrahydrocolumbamine, and to compare the pharmacokinetic parameters of these components to illustrate the influences of XEO on NXEO in normal rats...

Hypoxia may induce apoptosis and autophagy to promote cardiomyocyte injury. The present study investigated the effect of berberine, a natural extract of Rhizoma Coptidis, on hypoxia‑induced autophagy and apoptosis in the H9c2 rat myocardial cell line. Expression levels of apoptosis and autophagy markers were upregulated in H9c2 myocytes during hypoxia and cell viability was reduced. However, berberine significantly reduced hypoxia‑induced autophagy in H9c2 myocytes, as demonstrated by the ratio of microtubule‑associated proteins 1A/1B light chain 3 I/II and the expression levels of B‑cell lymphoma 2 (Bcl‑2)/adenovirus E1B 19 kDa protein‑interacting protein 3, and promoted cell viability...

Liang Chen, Xin Wang, Youping Liu, Xin Di
A novel strategy was developed for dual-target screening of bioactive components from traditional Chinese medicines (TCMs). This strategy was based on the use of low-cost microporous hollow fibers filled with target enzymes as baits to "fish out" the ligands in TCM extracts, followed by identification of the ligands dissociated from the target-ligand complexes by liquid chromatography-mass spectrometry. Ganjiang Huangqin Huanglian Renshen Decoction (GHHRD), a classical TCM prescription for diabetes treatment, was chosen as a model sample to evaluate the feasibility of the proposed strategy...

Here, we developed a new synthetic lethal strategy for further optimizing the eradication of cancer stem cells (CSCs). Briefly, we show that chronic treatment with the FDA-approved antibiotic Doxycycline effectively reduces cellular respiration, by targeting mitochondrial protein translation. The expression of four mitochondrial DNA encoded proteins (MT-ND3, MT-CO2, MT-ATP6 and MT-ATP8) is suppressed, by up to 35-fold. This high selection pressure metabolically synchronizes the surviving cancer cell sub-population towards a predominantly glycolytic phenotype, resulting in metabolic inflexibility...

BACKGROUND: While the incidence of colorectal cancer (CRC) is steadily increasing, screening for CRC with conventional approaches is not routinely performed in China. Noninvasive screening methods are attractive options to resolve this issue. Syndecan-2 (SDC2) is frequently methylated in CRC. However, the value of a stool test of methylated SDC2 for the detection of CRC is unknown. METHODS: Methylation status of SDC2 was tested in cell lines and 398 colorectal tissue samples, and further evaluated with 497 stool samples, including 196 from CRC patients, 122 from adenoma patients, and 179 from normal individuals, using real-time methylation-specific PCR (qMSP)...

Localized surface plasmon resonance (LSPR) biosensors allow label-free detection of small molecules in molecular binding events; however, they are limited by a relatively low sensitivity and narrow dynamic range. Here, we report highly sensitive small-molecule detection by LSPR peak shift exploiting the G-quadruplex (GQx) structure-binding characteristic of known GQx binders to enhance the LSPR signal of a plasmonic aptasensor. Six known GQx binders (thiazole orange, malachite green, crystal violet, zinc protoporphyrin IX, thioflavin T, and berberine) were tested for their ability to enhance the LSPR signal...

The interaction between berberine chloride and β-cyclodextrin (β-CyD) is investigated via 2D asynchronous UV-Vis spectrum. The occurrence of cross peaks around (420nm, 420nm) in 2D asynchronous spectrum reveals that specific intermolecular interaction indeed exists between berberine chloride and β-CyD. In spite of the difficulty caused by overlapping of cross peaks, we manage to confirm that the 420nm band of berberine undergoes a red-shift, and its bandwidth decreases under the interaction with β-CyD. The red-shift of the 420nm band that can be assigned to n-π* transition indicates the environment of berberine becomes more hydrophobic...
