Alcohol addiction can cause brain dysfunction and many other diseases. Recently, increasing evidences have suggested that gut microbiota plays a vital role in regulating alcohol addiction. However, the exact mechanism has not yet been elucidated. Here, our study focused on the intestinal bacteria alternations and their correlations with alcohol-induced neuropsychic behaviors. When consuming alcohol over 3-week period, animals gradually displayed anxiety/depression-like behaviors. Moreover, 16S rRNA sequencing showed significant intestinal microflora dysbiosis and distinct community composition...

Scleroderma is an inflammatory autoimmune disease which begins with inflammation due to tissue injury and advances to progressive accumulation of extracellular matrix resulting in scarring and hardening of the skin. Inflammation is a salutary response to tissue injury caused by varied factors. While inflammation is required for systematic wound healing, dysregulated chronic inflammation often leads to tissue scarring. Prominent role of inflammation in pathology and physiology makes it a double edge sword. The objective of this study was to investigate the role of Withaferin A (WFA), a steroidal lactone from Withania somnifera in a 28-day murine model of bleomycin-induced experimental scleroderma...

People are exposed to a number of environmental, occupational, and therapeutic toxic agents which may be natural or man made. These hazardous substances may manifest as direct side effects on the function of organs or indirectly induced alteration of gene expression, cancer-associated metabolic pathways, and/or alter homeostasis. Lycopene, as a one of the most potent antioxidant, is found in fruits and vegetables. High-intake of lycopene has been shown to be effective in decreasing the risk of both natural toxins including mycotoxins, bacterial toxins, and chemical toxins including heavy metals, pesticides as well as herbicides...

Bisdemethoxycurcumin (BDMC) was a natural curcuminoid with many bioactivities present in turmeric (Curcuma longa L.). However, the disposition mechanisms of BDMC via uridine 5'-diphospho-glucuronosyltransferase (UGT) metabolism still remain unclear. Therefore, we aimed to determine the potential efflux transporters for the excretion of BDMC-O-glucuronide. Herein, chemical inhibition assays (Ko143, MK571, dipyridamole, and leukotriene C4) and biological inhibition experiments including stable knocked-down of breast cancer resistance protein (BCRP), multidrug resistance-associated proteins (MRPs) transporters were both performed in a HeLa cell line stably overexpressing UGT1A1 established previously...

Oral administration of lysophosphatidic acid (LPA), a critical intercellular lipid mediator, exerts wound healing and antiulcer effects on gastrointestinal system. To evaluate effects of food-derived LPA on body homeostasis, we measured LPA levels by liquid chromatography-tandem mass spectrometry in chows, feces, plasma, liver, and visceral fat of mice fed a normal or high-fat chow supplemented with or without LPA-rich soybean phospholipids for 30 days. Reductions in daily body weight gains and visceral fat mass were mainly related to lower chow intake by mice fed the LPA-rich high-fat chow, whereas reduced body weight gains and fat mass were mainly related to decreased intestinal triacylglycerol absorption in mice fed LPA-rich chow...

Berberine, a widely used isoquinoline alkaloid in traditional Chinese medicine, has been proved to be a potential candidate in liver cancer therapy. However, the low therapeutic dose in the tumor target which is due to the poor solubility and oral bioavailability has limited its clinical application. In this study, fluorescent self-carried Berberine microrods (Ber-MRs) were prepared in gram-scale through a facile and cheap antisolvent precipitation method. Ber-MRs exhibited good optical properties, pH-responsive drug release behavior and selective and safe antitumor performance in vitro and in vivo without obvious toxicity...

Migration and metastasis of tumor cells greatly contributes to the failure of cancer treatment. Recently, the extracellular protein secreted protein acidic and rich in cysteine (SPARC) has been reported closely related to tumorigenesis. Some articles have suggested that SPARC promoted metastasis in several highly metastatic tumors. However, there are also some studies shown that SPARC acted as an antitumor factor. SPARC-induced epithelial-to-mesenchymal transition (EMT) in melanoma cells and promoted EMT in hepatocellular carcinoma...

Mutation in Cu/Zn superoxide dismutase (SOD1) at position 85 from glycine to arginine was found to be a prominent cause of aggregation characterized by an increased content of β-sheets in familial amyotrophic lateral sclerosis (fALS). Various literatures reported that natural polyphenols could act as a β-sheet breaker and therefore, treated as a potential therapeutics against various aggregated proteins involved in neurodegenerative disorders. Through computational perspective, molecular docking, quantum chemical studies, and discrete molecular dynamics were implemented to study the binding and structural effect of natural polyphenols, kaempferol, and kaempferide on mutant SOD1...

Over the last decades, the incidence of type 2 diabetes (T2D) is increasing substantially. Emerging evidences from epidemiological studies have shown the association between higher intake of soy isoflavones and reduced risk of T2D and its associated health risks. Daidzein, a soy isoflavone, has been found to have a promising therapeutic potential in managing T2D pathophysiology. Fermented soybean is the major source of daidzein; however, it can also be formed via the consumption of its glycosylated moiety, daidzin with subsequent hydrolysis by intestinal bacterial enzyme...
