    • 摘要: Traditional Chinese preserved egg products have exhibited some anti-inflammatory effects,but their mechanisms of action remain unknown.This study aimed to investigate the anti-inflammatory effects of preserved egg white(PEW)treatment on dextran sulfate sodium(DSS)-induced colitis in mice and the underlying mechanisms.The results showed that treatment with PEW in mice with DSS-induced colitis for 14 days effectively improved the clinical signs,inhibited the secretion and gene expression of pro-inflammatory cytokines,and reduced myeloperoxidase(MPO)activity and oxidative stress levels.In addition,western blotting results showed that PEW significantly suppressed DSS-induced phosphorylation levels of nuclear factor-kappa B(NF-κB)p65 and p38 mitogen-activated protein kinase(MAPK)in colon tissues of mice with colitis.PEW also enhanced the production of short-chain fatty acids(SCFAs)and modulated gut microbiota composition in mice with DSS-induced colitis,including increasing the relative abundance of beneficial bacteria Lachnospiraceae,Ruminococcaceae and Muribaculaceae,and reducing the relative abundance of harmful bacteria Proteobacteria.Taken together,our study demonstrated that preserved egg white could alleviate DSS-induced colitis in mice through the reduction of oxidative stress,modulation of inflammatory cytokines,NF-κB,MAPK and gut microbiota composition.

    • 摘要: Objective:To explore the possible neuroprotective activities of Humulus japonicus extract against Parkinson's disease(PD)in a cellular model.Methods:PD was modeled in PC12 cells using 6-hydroxydopamine(6-OHDA).The cell activity,intracellular levels of reactive oxygen species(ROS),anti-oxidative and anti-apoptotic effects,and other related indicators and related signaling pathways were evaluated to elucidate the neuroprotective effects of Humulus japonicus extract.Results:Humulus japonicus extract exhibited anti-oxidative and anti-apoptotic effects in 6-OHDA-stimulated PC12 cells.It also reduced oxidative stress-induced ROS accumulation;upregulated antioxidant enzymes,such as glutathione,catalase,heme oxidase-1,and 8-oxguanine glycosylase 1;promoted cell survival by decreasing BAX and increasing Bcl-2 and sirtuin 1 expression via the MAPK and/or Nrf2 signaling pathways.Conclusions:Humulus japonicus extract has antioxidative and anti-apoptotic effects and could be developed as a promising candidate for preventing and treating oxidative stress-related neurodegenerative diseases.

    • 摘要: Endometrial cancer remains to be a major type of malignancy in threatening female life.Molecular insights in advancing our understanding of endometrial tumorigenesis are much needed.We here report that a less-studied protein Dihydropyrimidinase like 3(DPYSL3)is a potent tumor suppressor.DPYSL3 is uniquely regulated by wild type p53(wtp53),and its expression is at the highest level when cells carry wtp53 and are exposed to hypoxia.We reveal that wtp53 can bind DPYSL3 promoter to enhance DPYSL3 expression and in turn,the elevated DPYSL3 can restrain cancer cell proliferation and invasion in vitro and in vivo.Importantly,we observe that DPYSL3 can interfere with MAP kinase pathway,supported by a substantially reduced level of phosphorylated ERK in cells with high expression of DPYSL3.Furthermore,we identify the specific region of DPYSL3 that is responsible for its interaction with MEK and a subsequently reduced activity of ERK.In combination of molecular docking and mutagenesis analysis,we validated that the therapeutic implication of 17 A.A.s of DPYSL3,which can reduce the activity of the MAPK pathway and inhibit endometrial tumor cell growth in vitro and in vivo.Therefore,our study not only demonstrates in-depth understanding of human tumorigenesis,especially endometrial tumor,but also only provides a therapeutic potential to develop an effective tool to fight against human malignancy.

    • 摘要: 紫外线是影响人类皮肤氧化的主要外部驱动器。紫外线轻者将会导致皮肤老化、银屑病、皮肤炎症和痤疮,严重将诱导皮肤癌症。长期暴露在阳光下,透过臭氧层的紫外线辐射能穿透不同深度的皮肤层,进而引起直接和间接的生物损伤反应,包括DNA损伤和活性氧诱导的氧化应激等。蓝光是可见光中波长最小、能量最大的波段,其诱导的皮肤损伤类似于紫外线辐射。益生菌具有抗氧化、抗衰老和抗炎特性,并且能够抵抗紫外线、蓝光诱导的氧化应激,从而可以用来保护皮肤免受光损伤,相应的功能性益生菌可成为抵抗紫外线、蓝光辐射诱导皮肤损伤的辅助食物。
