Abstract:2,3,7,8-tetrachlorodibenzodioxine (TCDD) was a highly toxic contamination and detected in the environment and food. It can be bio-magnified through food chain and bio-accumulate in human bodies, then cause various adverse health effects. Autophagy was a self-regulating process that degraded proteins and organelles in cells. The disruptions of autophagy balance have been bound up with multiple diseases and metabolic processes. In this paper, we detected the effects of TCDD on autophagy in RAW 264.7 cells and traced the molecular mechanism. The results showed that TCDD dose-dependently inhibited autophagy with the range from 0 to 10nM. Further, we found that this inhibition of autophagy was due to the decrease of p-Akt/Akt and increase of p-mTOR/mTOR expression. In addition, the autophagy inhibition caused by TCDD was resumed by using reversible mTOR inhibitor (rapamycin) and a selective Akt inhibitor (LY294002). This evidence showed that Akt/mTOR signaling pathway plays an important role in the autophagy induced by TCDD in RAW 264.7 cells. Our study confirmed the autophagy injury of TCDD on RAW 264.7 macrophages and the mechanism of TCDD toxicity was supplemented at the molecular level. | |||

Abstract:In modern dairy industry, thermal processing is applied for safety concern of microbial risk during goat milk (GM) processing, which would concern the stability of milk proteins. In this paper, we studied the outcomes of thermal treatments (pasteurization, spray drying and ultra-high temperature (UHT)) commonly practiced in the milk industries on the denaturation of protein structure and physicochemical properties of GM. Confocal scanning microscopy illustrated that high heat treatments strengthened the milk fat globules size (MFGs) of GM. The results from circular dichroism and fluorescence spectroscopy presented that spray drying and UHT both treatments made significant transformations in protein structure of GM. Moreover, these treatments also decreased the total sulfhydryl concentration and zeta potential in milk proteins, while surface hydrophobicity increased significantly indicating that thermal treatment had a great impact on GM proteins. Whereas, pasteurization had the least effect on serum proteins compared to raw milk serum. This study provided a great understanding of physicochemical and structural changes of GM underlying commercial thermal treatments. | |||

Abstract:White spots are commonly found in bean-based fermented food, which will significantly lower the product quality. This study aimed to analyze the composition of white spots and further reveal the source and influencing factors of white spots in bean-based fermented food using soybean paste as study model. The results showed that white spots were mainly composed of 40.96% free tyrosine and 37.94% tyrosine-rich peptides. During soybean paste fermentation, tyrosine was found to be produced by the actions of proteolytic enzymes secreted by Aspergillus oryzae 3.042 and the excessive accumulation of tyrosine in soybean paste led to the formation of white spots. Among all influencing factors, high temperature treatment favored the formation of white spots. The existence of soy peptone and phenylalanine would postpone the precipitation of tyrosine while promote the aggregation of the tyrosine precipitation. Field Emission Scanning Electron Microscope (FESEM) analysis showed that tyrosine accumulated around the protein particles and treatment at 120 C would disrupt the structure of tyrosine-protein complex. Based on the above results, we proposed that treatment of soybean paste at temperature lower than 80 C was the current practically applicable method to control the formation of white spots in soybean paste. | |||

Abstract:No therapeutic options currently exist for nonalcoholic fatty liver disease (NAFLD). Although commonly prescribed for cardiovascular diseases, Danshen (Salvia miltiorrhiza Bunge) has been used historically in folk medicines against chronic liver diseases, but its potential in NAFLD therapy remains uncertain. Here we reported that Tanshinone IIA (TAN-IIA), a principal constituent of Danshen, effectively ameliorated experimental NAFLD via transactivation of AMP-activated protein kinase. Using a mouse model, we established that tanshinone IIA effectively attenuated high-fat-diet induced obesity, hepatomegaly and liver steatosis. Mechanistically, we found that β2-adrenergic receptor (β2-AR) was down-regulated in liver tissues of obese mice. Tanshinone IIA might function as a β2-AR agonist, increase the intracellular cAMP levels, and turn on liver kinase B1 (LKB1)-AMP-activated protein kinase (AMPK)-acetyl-CoA carboxylase 2 (ACC2) signaling axis to promote fatty acid oxidation. Collectively, tanshinone IIA might merit investigation as a potential therapeutic agent for NAFLD especially in those patients with obesity. | |||
