    Abstract Pectin, a kind of dietary fiber, has attracted much attention owing to its beneficial effect on human health in recent years. In this study, the effects of both 'Ganzhou' navel orange peel pectin (GOP) and modified GOP (MGOP) on type 2 diabetes (T2DM) were investigated. The results indicated that GOP and MGOP intervention had positive effects on T2DM in C57BL/6 mice. After modification, pectin can be changed into low methoxy pectin (LMP) and the content of GalA can increase, which endow MGOP with significant effects on improving lipid metabolism (TC, TG, and LDL-C decreased by 30.46%, 50%, and 37.56%, respectively, and HDL-C increased by 56%) and OGTT, further reducing insulin resistance (insulin decreased by 74.35%). In addition, MGOP was superior to GOP in improving oxidative stress (GSH and GSH-Px increased by 52.05% and 29.08% respectively, and MDA decreased by 84.02%), inhibiting inflammation and promoting SCFA synthesis. 16S rRNA analysis showed that MGOP changed the composition of intestinal microbiota in diabetic mice, decreased the abundance of

    Abstract This study aimed to investigate the mechanisms of nature and modified 'Guanximiyou' pummelo peel pectin (GGP and MGGP) in alleviating T2DM through in vitro and in vivo. After modification, pectin was transformed from high methoxy pectin (HMP) to low methoxy pectin (LMP), and the content of galacturonic acid was increased. These made MGGP have stronger antioxidant capacity and better inhibition effect on corn starch digestion in vitro. In vivo experiments have shown that both GGP and MGGP inhibited the development of diabetes after 4 weeks of ingestion. However, MGGP can more effectively reduce blood glucose and regulate lipid metabolism, and has significant antioxidant capacity and the ability to promote SCFAs secretion. In addition, 16S rRNA analysis showed that MGGP changed the composition of intestinal microbiota in diabetic mice, decreased the abundance of Proteobacteria, and increased the relative abundance of Akkermansia, Lactobacillus, Oscillospirales and Ruminococcaceae. The phenotypes of the gut microbiome also changed accordingly, indicating that MGGP can inhibit the growth of pathogenic bacteria, alleviate intestinal functional metabolic disorders and reverse the potential risk of related complications. Altogether, our findings demonstrate that MGGP, as a dietary polysaccharide, may inhibit the development of diabetes by reversing the imbalance of gut microbiota.

    Abstract Objectives: This study aimed to investigate the hypoglycemic effect of highland barley β-glucan (HBG) on mice with type 2 diabetes (T2D), and determine whether the hypoglycemic effects are related to modulations of the gut microbiota.
    Methods: T2D was induced with a high-fat diet and streptozotocin in the mice. HBG was orally administered to mice with T2D for 4 wk, and biochemical indices were analyzed in the serum and liver. Fecal samples were collected and analyzed with high-throughput 16S ribosomal RNA sequencing.
    Results: Intake of HBG for 4 wk suppressed the body weight, as well as liver and heart indices, and regulated the levels of fasting blood glucose, serum insulin, blood lipid, oxidative damage, and inflammatory reaction in mice with T2D. Furthermore, HBG reversed the gut microbiota dysbiosis in mice with T2D by increasing the abundance of Lachnospiraceae_UCG-006, Streptococcaceae, and Eggerthellaceae, and by decreasing the abundance of Parasutterella.
    Conclusions: Our findings indicate that the antidiabetic abilities of HBG might be related to the improvement of gut microbiota imbalance.

    Abstract Quinalizarin (Quina) is one of the main components of many herbal medicines and has good anti‐tumor activity. However, the exact mode of cytotoxic action and signaling pathways on Quina in human esophageal cancer has not yet been confirmed. In this study, we explored the anticancer effect of Quina against human esophageal cancer HCE‐4 cells and the underlying mechanisms. The results of the Cell Counting Kit‐8 (CCK‐8) assay showed that Quina inhibited the viability of human esophageal cancer HCE‐4 cells in a dose‐dependent and time‐dependent manner. It also inhibited HCE‐4 cells proliferation and induced apoptosis by increasing the levels of Bad, caspase‐3, and PARP, decreasing the level of Bcl‐2. The results of the cell cycle analysis suggested that Quina arrested HCE‐4 cells in the G0/G1 cycle by downregulating cyclin‐dependent (CDK) 2/4, cyclin D1/E and upregulating the levels of p21 and p27. We also found that Quina activated mitogen‐activated protein kinase (MAPK) and inhibited the signal transducer and activator of transcription‐3 (STAT3) and nuclear factor kappa B (NF‐κB) signaling pathways. Furthermore, Quina significantly increased intracellular reactive oxygen species (ROS) level. The pretreatment of N‐acetyl‐L‐cysteine (NAC) blocked the apoptosis induced by Quina and inhibited the activities of MAPK, STAT3, and NF‐κB signaling pathways. These results indicate that Quina induces the apoptosis in HCE‐4 cells, which is via accumulating ROS generation and regulating MAPK, STAT3, and NF‐κB. In conclusion, this study demonstrated that Quina have good therapeutic effects on human esophageal cancer cells.

    Abstract The study investigated the protective effects of kaempferol galactoside (KG) components in mice, which were separated from Jindai soybean leaves (JDL) and mainly composed by two kaempferol galactosides. Further, KG-related metabolites in serum of mice were identified by Tof-MS. Results showed that both JDL and KG prevented the CCl4-induced increases in serum aspartate aminotransferase and serum alanine aminotransferase. Additionally, mice treated with KG had significantly decreased TBARS and TNF-alpha levels, compared to CCl4-treated mice. Serous analysis showed that kaempferol, glucuronidated kaempferol and methylated kaempferol with a glucuronic acid moiety were identified in the serum of mice fed unripe soybean leaves or kaempferol galactosides isolated from the leaves. The results indicated that kaempferol 3-O-galactoside connected to other glycosides via galactose might be hydrolyzed in the gastro-intestinal tract and/or epithelium cells to release kaempferol, followed by glucuronidation and/or methylation in the liver to contribute to a reduction in liver injury. The use of raw leaves containing kaempferol galactosides as food materials may contribute to a reduction in oxidation-related diseases.

    Abstract Anti-diabetic potential of luteolin (LU) and luteolin-7-O-glucoside (LUG) were investigated in the amount of equimolar on KK-Aʸ mice. The results showed that both of LU and LUG significantly improved blood glucose, HbA₁c, insulin, and HOMR-IR levels. Anti-inflammatory and anti-oxidative effects of the LU and LUG were also proved. Furthermore, TGs in serum and liver were significantly decreased in the LU and LUG groups, as well as the mRNA expression of fat acid expression-related genes (SREBP-1c), compared to the basal diet group (CON). When compared the effects between the LU and LUG groups, TGs of the LU group were lower than those of the LUG group, accompanied with significantly decreased FAS activity and SREBP-1c expression in liver. These results suggested that both LU and LUG had positive effects of anti-diabetes on KK-Aʸ mice, but LU more potently ameliorated diabetes than LUG, which might be attributed to the inhibitory of lipid synthesis.
