Project description:To understand the complex mechanism of estrogen action, multiple assays based on different biological principles is important. Here, multiple assays based on cell, protein and transcription assays were used to evaluate estrogenic activity of soymilk extracts before and after fermentation, and four soy compounds, genistein and daidzein, and their glycosides, genistin and daidzin, respectively. The data obtained by a transcription assay, RNA-sequencing (RNA-seq), was further examined by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database analysis to understand cell functions, i.e. biological processes and metabolic pathways. Among the cell functions identified, the sets of genes for cell division/cell cycle and DNA replication/DNA repair are significantly up-regulated, whereas those for autophagy are significantly down-regulated, which explains well the enhanced activity of cell proliferation by these materials. The applications of estrogenic activity of soymilk extracts and soy flavonoids, and the contribution of fermentation, include pharmacological benefits, such as bone protection/bone regeneration, cancer chemoprevention, neuroprotection and the treatment of menopausal syndromes.
Project description:The purpose of this study is to analyze the key enzyme systems of Fermented Food Microorganisms, and trace its beneficial functional microorganisms through key enzymes. The test sample was a traditonal fermented food. To improve the accuracy and credibility of protein Information, 12 test parallels were randomly selected for the following analysis.
Project description:In this study, a metaproteomic approach was used for a detailed analysis of the structure of the microbial community, temporal changes and the functional role of the microbiota during pozol fermentation.
