Project description:The microarray results showed that linalool sitimulation of lipid-loaded HepG2 cells rewired the hepatic transcriptome profile, with linalool being comparable to those of fenofibrate. Total of 8,988 genes that were commonly and significantly expressed in all experimental groups, including control hepatocytes, lipid-loaded hepatocytes, and lipid-loaded hepatocyted stimulated with linalool or fenofibrate, respectively, to compare the transcriptome profile of linalool (1mM) with those of hypotriglyceridemic drug, fenofibrate (100 ?M). Lipid loading of hepatocytes notably changed hepatic transcriptome profile, where 77 % of the selected genes showed >20% changes in expression (fold change > 1.2 or fold change <0.8). However, linalool stimulation of lipid-loaded cells showed that 48 % of the selected genes had expression changes of >20%. Thus, 29 % of the selected genes became to show less than 20% changes in expression after linalool stimulation compared to the lipid-loaded condition. Fenofibrate showed 46 % of the selected gene expression changes of >20%. Thus, 31 % of the seleted genes fell into the <20% change category compared to the lipid-loaded condition after fenofibrate stimulation. Untreated control vs. lipid-loaded HepG2 cells (3 biological replicates), untreated control vs. lipid-loaded HepG2 cells treated with fenofibrate (3 biological replicates), untreated control vs. lipid-loaded HepG2 cells treated with linalool (2 biological replicates). One replicate per array

Project description:Grape volatiles include a great number of compounds, among which monoterpenes, alcohols,esters and carbonyls were found.Grape may be divided into aromatic and non-aromatic varieties. ‘Shine Muscat’ belongs to the aromatic cultivar. The most abundant free compounds detected in Muscat grape were linalool, geraniol, citronellol, nerol. Grapevine (Vitis vinifera L.) is an economically important and widely cultivated fruit crop. Grape quality is important for its market value and is largely decided by its taste and aroma.Gas-chromatograph mass-spectrometry (GC-MS) was performed to observe changes of the volatile compounds.
Project description:ChIP-seq analysis of HepG2 cells revealed that many of the target genes of LSD2 were related to lipid metabolism. We found that LSD2 is an important epigenetic regulator of hepatic lipid metabolism. Examination of LSD2/DNA interaction in HepG2 cells in normal condition.
Project description:ChIP-seq analysis of LSD2-depleted HepG2 cells revealed that many of the target genes were related to lipid metabolism. We found that LSD2 is an important epigenetic regulator of hepatic lipid metabolism. Examination of LSD2/H3K4me1 interaction in control and LSD2-knockdowned HepG2 cells.
Project description:Transcriptome analysis of LSD2-depleted HepG2 cells revealed that many of the target genes were related to lipid metabolism. We found that LSD2 is an important epigenetic regulator of hepatic lipid metabolism. We depleted LSD2 in HepG2 human hepatic cells using three different siRNAs, and then carried out an expression microarray experiment.
Project description:Plants can synthesize a wide range of terpenoids in response to various environmental cues. However, the specific regulatory mechanisms governing terpenoid biosynthesis at the cellular level remain largely elusive. Herein, we employed single-cell RNA sequencing (scRNA-seq) to comprehensively characterize the transcriptome profile of cotton leaves and established a hierarchical transcriptional network regulating cell-specific terpenoid production.
