Project description:Untargeted-metabolomics LC-MS/MS analysis of commercial natural products pool, analyzed with different DDA settings with the objective to find the best one.
Project description:Genomic DNA of Col-0, Van-0 and their mixture at different proportion were labeled using Bioprime randon labeling kit. A total of 16ug labelled products were hybridized to AtSNPtile1. This experiment is to test whether the log allele intensity ratio efficiently detects the allelic variation within targets.
Project description:Genomic DNA of Col-0, Van-0 and their mixture at different proportion were labeled using Bioprime randon labeling kit. A total of 16ug labelled products were hybridized to AtSNPtile1. This experiment is to test whether the log allele intensity ratio efficiently detects the allelic variation within targets. Templates include four Col genomic DNA replicates, four Van genomic DNA replicates, three Col and Van 1:1 mixture replicates, and one of each 1:2, 1:3, 1:5, 2:1, 3:1, 5:1 Col and Van mixture. Single chanel. Total 17 samples.
Project description:Natural products exhibit potential as candidates for developing multi-target agents for Alzheimer's disease treatment. The aim of this study is to utilize network-based medicine to identify novel natural products for Alzheimer's disease, and investigate their efficacy and mechanisms of action. In this study, we identified (-)-Vestitol and Salviolone as new potential natural products for treating Alzheimer's disease via an Alzheimer's disease-related pathway-gene network. Both natural products improved the cognition of APP/PS1 transgenic mice, reduced Aβ deposition, and lowered soluble toxic Aβ levels in the brain. Notably, a synergistic effect was observed when the two natural products were combined. Transcriptomic analysis and qRT-PCR experiments revealed that the synergistic mechanism of (-)-Vestitol and Salviolone combination is associated with the regulation of a broader range of AD-related pathways and genes, particularly the neuroactive ligand-receptor interaction pathway and calcium signaling pathway.
