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 ...
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, ...
New Insights for Ets2 Function in Trophoblast using Lentivirus-Mediated Gene Knockdown in Trophoblast Stem Cells
(2010)
Mouse trophoblast stem (TS) cells represent a unique in vitro system that provides an unlimited supply of TS cells for the study of trophoblast differentiation and TS cell self-renewal. Although the mouse transcription ...
Depletion of histone N-terminal-acetyltransferase Naa40 induces p53-independent apoptosis in colorectal cancer cells via the mitochondrial pathway
(2016)
Protein N-terminal acetylation is an abundant post-translational modification in eukaryotes implicated in various fundamental cellular and biochemical processes. This modification is catalysed by evolutionarily conserved ...
Activation of endogenous FAK via expression of its amino terminal domain in xenopus embryos
(2012)
Background: The Focal Adhesion Kinase is a well studied tyrosine kinase involved in a wide number of cellular processes including cell adhesion and migration. It has also been shown to play important roles during embryonic ...
Evidence that a metabolilte of equine estrogens, 4-hydroxyequilenin, induces cellular transformation in vitro
(2001)
Estrogen replacement therapy has been correlated with an increased risk of developing hormone-dependent cancers. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin and equilin which are components of the ...
The interplay between DSL proteins and ubiquitin ligases in Notch signaling
(2005)
Lateral inhibition is a pattern refining process that generates single neural precursors from a field of equipotent cells and is mediated via Notch signaling. Of the two Notch ligands Delta and Serrate, only the former was ...
