Molecular networking-based discovery of anti-inflammatory chromene dimers from Melicope pteleifolia.

Kakumu Yuya Y Thi Nguyen Minh Tu MT Mitsunaga Tohru T

Phytochemistry 20220712

With the aid of a feature-based molecular networking strategy, five undescribed C<sub>2</sub> and C<sub>1</sub> symmetric chromene dimers, namely, melptelchromenes A-E, were isolated from the leaves of Melicope pteleifolia. Four asymmetric dimers were found to be racemates and were resolved by chiral phase HPLC analyses. Their structures, including absolute configurations, were elucidated by HRMS, NMR spectroscopy, and quantum mechanical calculations of ECD spectra and NMR chemical shifts. Melpt ...[more]

Spatial and temporal proteomic of HCMV-infected cells

Project description:Project for the study of spatial and temporal alterations in organelle proteins during HCMV infection. Two datasets are included, one for label-free quantification and one for TMT quantification. Samples were collected at 5 time points of infection (24, 48, 72, 96, and 120 hours) and subject to organelle fractionation. One non-infected sample was included for the label-free analysis, and 5 non-infected samples (one per time point) were included for the TMT dataset. The nucleus and cytosolic fractions were removed by differential centrifugation, leaving a crude organelle fraction. The crude organelle fraction was further fractionated by density gradient ultracentrifugation into sicx fractions.

Label free comparative proteome analysis of Arabidopsis lipid droplets from 6 week old leaves

Project description:Lipid droplets from 6 week old Arabidopsis leaves were purified on sucrose gradient. The abundance of the proteins in the lipid droplet fraction was established by label free and compared to soluble, membrane and plastoglobule fractions, and total leaf extract in order to identify the proteins specifically enriched in lipid droplets. Three independent biological replicates, from three independent cultures were performed. For each biological replicates, three preparations of lipid droplets (and other fractions) within each of the three independent cultures were obtained.

RNA-seq analysis of differentially expressed genes between stromal vascular fraction (SVF) from inguinal white adipose tissue (iWAT) of mice treated with medicinal herb extract (MHE) and Phosphate-buffered saline (PBS)

Project description:To assess the influences of a crude medicinal herb extract (MHE) on the immune composition and function in inguinal white adipose tissue (iWAT), we isolated iWAT stromal vascular fractions (SVFs) from control (PBS) and MHE-treated mice and performed RNA-seq analysis. iWAT SVF of mice treated with MHE was defined as the treatment group. Phosphate-buffered saline (PBS) treatment was used as the control group. Then RNA-Seq experiment was performed by OE Biotech Co., Ltd. (Shanghai, China) to analyze gene expression changes in iWAT SVF.

A modular system regulates specialized metabolite pathway branch choice in the medicinal plant Catharanthus roseus

Project description:This dataset belongs to a set of three RNA-Seq experiments that were carried out to study the regulation of monoterpenoid indole alkaloid production in the medicinal plant Catharanthus roseus. For this dataset, C. roseus stems were dissected to separate the epidermis from the lower tissues. Leaves were dissected to obtain veins and veinless leaves. As controls, undissected leaves and stems were used. Three biological replicates were analyzed per sample.
