The results showed water was predominantly in free status during the three stages of seed germination divided. Statistical analysis (PCA, OPLS-DA, KEGG) of 53 metabolites at different germination stages revealed the key metabolites of linoleic, flavonoid and phenylalanine biosynthesis during the seed germination. Furthermore, flavonoids biosynthesis was identified as the pathway with the largest difference significance at the second and third stages, while linoleic and phenylalanine metabolisms were screened out as the major pathways with most impact factors in the first and second and the third stage, respectively. The analysis provided valuable insights into the nutrient generation during Tartary buckwheat seeds germination.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":"33 1","pages":"692 - 708"},"PeriodicalIF":3.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44024267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Curcumin significantly inhibited the migration and invasion of HepG2 and SK-Hep-1 cells and inhibited the Wnt/β-catenin signalling pathway and reduced Bclaf1 expression in human hepatoma cells. In nude mice, intraperitoneal injection of curcumin significantly inhibited the growth of subcutaneously transplanted tumours and reduced lung metastasis of the tumour cells, downregulated the expression of Bclaf1, and inhibited the Wnt/β-catenin pathway.

A total of 29 differentially expressed miRNAs were identified in the liver after the LPS challenge. And 11 miRNAs were validated by qRT-PCR. In addition, the results of statistics of pathway enrichment showed that these miRNAs could be related to lipid metabolism response.

Inhibition of toll-like receptors 4 (TLR4) reduced the production of immunomodulators induced by HSR. Inhibition of mitogen-activated protein kinase (MAPKs), nuclear factor-κB (NF-κB) and phosphoinositide-3 kinase (PI3K) signaling attenuated the production of immunomodulators induced by HSR. Based on the results of this study, HSR was thought to activate macrophages through the production of immunomodulators and phagocytosis activation through TLR4-dependent MAPKs, NF-κB and PI3K signaling pathways.

Experimental data indicate that TAL has scavenging activity against UVB radiation-induced intracellular reactive oxygen species (ROS) compared to UVB controls. The contents of skin barrier-related factors in the groups were detected by Enzyme-linked immunosorbent assay (ELISA), then ELISA and quantitative polymerase chain reaction (qPCR) were used to detect changes in the inflammatory factors, apoptosis factors, and gene levels in the groups. Therefore, TAL stabilised the levels of inflammation, apoptosis, and skin barrier-related factors by regulating Mitogen-activated protein kinases/nuclear factor-k-gene binding (MAPK/NF-κB) signalling pathways, such as jun-amino-terminal kinase (JNK), p38, extracellular signal-regulated kinase (ERK), and NF-κB.
