Project description:Complex microbial metabolism is key to taste formation in high-quality fish sauce during fermentation. To guide quality supervising and targeted regulation, we analyzed the function of microbial flora during fermentation based on a previous metagenomic database. Most of the identified genes involved in metabolic functions showed an upward trend in abundance during fermentation. In total, 571 proteins extracted from fish sauce at different fermentation stages were identified. The proteins were mainly derived from Halanaerobium, Psychrobacter, Photobacterium, and Tetragenococcus. Functional annotation showed 15 pathways related to amino acid metabolism, including alanine, aspartate, glutamate, and histidine metabolism; lysine degradation; and arginine biosynthesis.
Project description:The myocardial tissues of the ischemic left ventricle and the peri-ischemic rim (an approximately 1 mm rim of normal-appearing tissues) were removed, and the remaining tissues that consisted of non-ischemic left ventricle were obtained for the transcriptional analysis. The total RNA was extracted from the myocardia from the sham (n = 3), myocardial ischemia model (n = 3), and a traditional Chinese medicine formula treated on myocardial ischemia (n = 3) groups. Beads that contained oligo were used to isolate the poly mRNA from the total RNA and then the rRNA was subsequently removed. The amplified library was sequenced on a HiSeq 2500 sequencing machine (Illumina, San Diego, California, USA) with a 50 bp SE strategy. Using CASAVA software, the images generated by the Illumina sequencers were converted into raw reads by base-calling.
Project description:Using high-throughput antibody microarray, through cross-sectional sample detection and verification of samples that had undergone physical changes over time, it was found that people with balanced constitution and dampness constitution in Chinese medicine showed differences in serum protein expression. The differences were expressed as the level changes of 19 proteins such as Dectin-2, Siglec-7, AIF and TACI. The research results provided the basis for the scientific expression of traditional Chinese medicine (TCM) constitution.
Project description:To identify biomarkers regulated by traditional Chinese medicine Astragalus membranaceus Fischer Bge. var. mongolicus Bge. Hsiao in colorectal cancer. We have identified several differentially expressed genes including microRNAs using Affymetrix HTA-2.0 array. In this dataset, we include the expression data obtained from colon cancer cell line HCT116 grafted into nude mice. The mice was treated either water or traditional Chinese medicine Astragalus membranaceus for 28 days. These data are used to obtain 1425 genes that are differentially expressed in response to Astragalus membranaceus treatment.
Project description:We investigated the effects of jeotgal (fermented fish sauce) on kimchi fermentation, with or without saeu-jeot and myeolchi-jeot. Bacterial community analysis showed that Leuconostoc, Weissella, Lactobacillus, and Tetragenococcus were the dominant genera; however, their succession depended on the presence of jeotgal. Leuconostoc gasicomitatum was the dominant species in kimchi without jeotgal, whereas Weissella koreensis and Lactobacillus sakei were the dominant species in kimchi with myeolchi-jeot and saeu-jeot, respectively. Metabolite analysis, using 1H NMR, showed that the amounts of amino acids and gamma-aminobutyric acid (GABA) were higher in kimchi with jeotgal. Increases in acetate, lactate, and mannitol contents depended on fructose consumption and were more rapid in kimchi with jeotgal. Moreover, the consumption of various amino acids affected the increase in kimchi LAB. Thus, the role of jeotgal in kimchi fermentation was related to enhancement of taste, the amino acid source, and the increases in levels of functional metabolites.
