Cancer chemopreventive activity of brassinin, a phytoalexin from cabbage
(1995)
Brassinin [3-(S-methyldithiocarbamoyl aminomethyl indole], a phytoalexin first identified as a constituent of cabbage, was synthesized and evaluated for cancer chemopreventive activity. Dose-dependent inhibition of ...
WR-1065, an active metabolite of the cytoprotector amifostine, affects phosphorylation of topoisomerase IIα leading to changes in enzyme activity and cell cycle progression in CHO AA8 cells
(1997)
The effects of WR-1065 (2-((aminopropyl)amino)ethanethiol) on cell cycle progression, topoisomerase (topo) IIα activity, and topo IIα phosphorylation in Chinese hamster ovary (CHO) cells have been investigated. Exposure ...
The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)
Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...
A serum-free and defined medium for the culture of mammalian postimplantation embryos
(2015)
Whole embryo culture (WEC) of postimplantation rodent embryos is widely used for the study of mammalian embryogenesis and developmental toxicity testing. Its major advantage is that it allows direct access to embryos for ...
The structure of a ferrous heme-nitro species in the binuclear heme a3/CuB center of ba3-cytochrome c oxidase as determined by resonance Raman spectroscopy
(2015)
Members of the cytochrome c oxidase family exhibit nitrite reductase activity. In this work, we have characterized a ferrous heme a3-nitro species in ba3-oxidase by resonance Raman spectroscopy. This provides the first ...
In vitro antioxidant activity and phenolic content of Cedrus brevifolia bark
(2014)
A raw extract and four extractive fractions were obtained from Cedrus brevifolia (Cyprus cedar) bark. They were all studied regarding the phenolic content and profile using spectrophotometry and HPLC-DAD-ESI-MS. The ...
Spatially and temporally regulated α6 integrin cleavage during Xenopus laevis development
(2008)
The α6 integrin is essential for early nervous system development in Xenopus laevis. We have previously reported a uPA cleaved form of integrin α6 (α6p), in invasive human prostate cancer tissue, whose presence correlates ...
In vivo imaging of quantum dots encapsulated in phospholipid micelles
(2002)
Fluorescent semiconductor nanocrystals (quantum dots) have the potential to revolutionize biological imaging, but their use has been limited by difficulties in obtaining nanocrystals that are biocompatible. To address this ...
Human pathogenic bacteria, fungi, and viruses in Drosophila
(2014)
Drosophila has been the invertebrate model organism of choice for the study of innate immune responses during the past few decades. Many Drosophila-microbe interaction studies have helped to define innate immunity pathways, ...
