Triterpenoid saponins in tea (Camellia sinensis) plants: biosynthetic gene expression, content variations, chemical identification and cytotoxicity
Tea saponins tea infusions anticancer activity biosynthesis gene expression tea processing
2023/4/20
Very little is known about saponins in tea and their biosynthesis in tea plants despite of theimportance. Here, we studied tea saponins and their biosynthesis genes. Saponins were promptly recovered i...
Investigating the Biosynthetic Pathways to Polyacetylenic Natural Products in Fistulina hepatica and Echinacea purpurea
Biological Chemistry Molecular Biology
2015/5/21
Polyacetylenic natural products, compounds containing multiple carbon-carbon triple bonds, have been found in a large collection of organisms. Radiochemical tracer studies have indicated that these bi...
Biosynthetic introduction of aryl bromide functionality into proteins
Aryl bromide proteins bacteria e. coli phenylalanine synthetase gene plasmid bear dihydrofolate reductase
2014/12/11
Incorporation of aryl bromide functionality into proteins was achieved via engineering the bacterial biosynthetic apparatus. A phenylalanine auxotrophic E. coli host was equipped with a phenylalanyl-t...
Effect of Age on the Auto-catalytic Ethylene Production and the Expression of Ethylene Biosynthetic Gene Dc-ACS1 in Petals of Long-life Carnations
Dianthus caryophyllus ethylene signal transduction
2011/2/24
We studied the effect of aging after the full-open stage on auto-catalytic ethylene production and the expression of genes for ethylene biosynthesis and signaling pathway following exogenous ethylene ...
Studies on Functional Analysis of Plant Starch Biosynthetic Enzymes
starch biosynthesis starch branching enzyme starch synthase subcellular localization
2008/4/20
About three centuries have already passed since Antoni van Leeuwenhoek observed the gelatinization of starch granule under a microscope in 1719. Now, many people know not only the word “starch,” but a...
The effects of matrix stiffness and RhoA on the phenotypic plasticity of smooth muscle cells in a 3-D biosynthetic hydrogel system
ECM (extracellular matrix) Hydrogel Mechanical properties Polyethylene oxide Smooth muscle cell
2010/1/7
Studies using 2-D cultures have shown that the mechanical properties of the extracellular matrix (ECM) influence cell migration, spreading,
proliferation, and differentiation; however, cellular mecha...
Biosynthetic hydrogel scaffolds made from fibrinogen and polyethylene glycol for 3D cell cultures
Scaffold Polyethylene glycol Hydrogel Mechanical properties Tissue engineering
2010/1/7
Tissue engineering scaffolds are fabricated from either biological materials, which provide biofunctional signals and interact well
with cells, or from synthetic polymers, which provide precise contr...
