Background Reprogramming of aerobic glycolysis occurs with HSCs activation and is associated with regression of liver fibrosis. Trigonelline (TRG), a plant alkaloid extracted from Trigonella foenum-graecum L seeds, has a variety of pharmacological effect. Purpose The current study investigated the hepatoprotective effect and mechanism of TRG against hepatic fibrosis by regulating glycolysis. Methods Anti-hepatic fibrosis effects of TRG were detected in thioacetamide (TAA)-induced hepatic fibrosis mice. HSCs or LX-2 were stimulated with TGF-β or conditioned medium (CM) from LPS-stimulated THP-1, then incubated with TRG, phloretin (PHL), rosiglitazone (RGZ), siRNA Glut-1 or plasmid with Glut-1. Results TRG significantly reduced serum transaminase levels, liver histopathological changes, excessive collagen deposition, inflammatory response, and neutrophil recruitment in TAA-induced mice. TAA increased hepatic Glut-1, HIF-1α and key enzymes of glycolysis expressions, while TRG completely reversed this effect. TRG also obviously regulated the combination of Glut-1 and HIF-1α to affect glycolysis in activated HSCs. TRG could inhibit α-SMA, IL-6, IL1R1, and HIF-1α expressions accompanying inhibition of Glut-1, function as PHL (Glut-1 inhibitor). Glut-1 silencing weakened α-SMA, IL-6, IL1R1, and HIF-1α expressions and enhanced the effect of TRG in activated LX-2. TRG inhibited LX-2 activation caused by Glut-1 overexpression, even demonstrated in interaction between LX-2 and macrophages. Further, TRG shown that improved fibrogenesis and inflammatory response by inhibiting Glut-1 compared with PHL in vivo . Conclusion TRG could ameliorate hepatic fibrosis through inhibiting ECM excessive deposition and inflammatory response. Inhibiting Glut-1-HIF-1α axis and glycolysis was a potential therapeutic strategy for TRG ameliorating liver microenvironment, further against hepatic fibrosis.

This study evaluated the effects of hot air drying (HAD), microwave drying (MD), vacuum drying (VD), sun drying (SD) and vacuum freeze drying (VFD) on the physical properties, bioactive components, antioxidant capacity, volatile components and industrial application of coffee peel. The results showed VFD could retain the appearance color, total phenolics (19.49 mg GAE/g DW), total flavonoids (9.65 mg CE/g DW), caffeine (3.15 mg/g DW), trigonelline (2.71 mg/g DW), and antioxidant capacities of fresh sample to the greatest extent, but its operating cost was significantly higher than other treatments and total volatile components were in the minimum levels. HAD and SD exhibited the highest loss rates of total phenols and antioxidant capacities, exceeding 50%. MD offered the lowest operating cost, superior retention of bioactive components, and the richest variety and quantity of volatile compounds. Therefore, it is recommended to use MD to dehydrate the coffee peel in actual production.

The potential mechanisms about the health risks of endogenous 3-MCPD remain elusive. Here, we researched the influences of 3-MCPD on the metabolic landscape of digested goat infant formulas via integrative UHPLC-Q-Orbitrap HRMS-MS/MS-based peptidomics and metabolomics (%RSDs ≤ 7.35 %, LOQ 2.99–58.77 μg kg −1 ). Digested goat infant formulas under 3-MCPD-interference caused metabolic perturbation by down-regulating levels of peptides VGINYWLAHK (5.98–0.72 mg kg −1 ) and HLMCLSWQ (3.25–0.72 mg kg −1 ) pertained to health-promoting bioactive components, and accelerated the down-regulation of non-essential amino acids (AAs, l -tyrosine 0.88–0.39 mg kg −1 , glutamic acid 8.83–0.88 μg kg −1 , and d -aspartic acid 2.93–0.43 μg kg −1 ), semi-essential AA ( l -arginine 13.06–8.12 μg kg −1 ) and essential AAs ( l -phenylalanine 0.49–0.05 mg kg −1 ) that provide nutritional value. Peptidomics and metabolomics interactions elucidated that 3-MCPD altered the stability of α-lactalbumin and d -aspartate oxidase in a dose-dependent manner, and affected the flavor perception of goat infant formulas, leading to a decline of nutritional value of goat infant formulas.

Drying is a crucial process in the production of tea. The effects of sun drying (SD), hot air drying (HAD), microwave drying (MD), vacuum drying (VD) and freeze drying (FD) on the color, taste, bioactive, and aroma of coffee pulp tea (CPT) were evaluated systematically. The results showed that FD could better retain the original color, total phenolics (4.75 mg/mL), trigonelline (0.31 mg/mL), chlorogenic acid (0.067 mg/mL), protocatechuic acid (0.81 mg/mL), and total soluble sugars (24.33 mg/mL) of CPT, but its drying time was longer (32.56 h), and the taste and flavor were the worst. HAD and SD displayed the highest loss rates of most bioactive components, exceeding 40%. In contrast, MD can better improve the quality of CPT, giving it a better color, superior retention of bioactive components, and the most attractive taste and aroma, and decrease the drying time by 66.1% and 96.5%, respectively. Overall, MD is a promising production method for obtaining high-value-added CPT products.

Phosphorylation is a key post-translational modification regulating protein function and biological outcomes. However, the phosphorylation dynamics orchestrating mammalian oocyte development remains poorly understood. In the present study, we apply high-resolution mass spectrometry-based phosphoproteomics to obtain the first global in vivo quantification of mouse oocyte phosphorylation. Of more than 8000 phosphosites, 75% significantly oscillate and 64% exhibit marked upregulation during meiotic maturation, indicative of the dominant regulatory role. Moreover, we identify numerous novel phosphosites on oocyte proteins and a few highly conserved phosphosites in oocytes from different species. Through functional perturbations, we demonstrate that phosphorylation status of specific sites participates in modulating critical events including metabolism, translation, and RNA processing during meiosis. Finally, we combine inhibitor screening and enzyme-substrate network prediction to discover previously unexplored kinases and phosphatases that are essential for oocyte maturation. In sum, our data define landscape of the oocyte phosphoproteome, enabling in-depth mechanistic insights into developmental control of germ cells.
