Dynamics of muscle fibre growth during postnatal mouse development - 2010
Rachel E. White, Anne-Sophie Biérinx, Viola F. Gnocchi, Peter S. Zammit
Abstract Background Postnatal growth in mouse is rapid, with total skeletal
muscle mass increasing several-fold in the first few weeks. Muscle growth can be
achieved by either an increase in muscle fibre number or an increase in the size
of individual myofibres, or a combination of both. Where myofibre hypertrophy
during growth requires the addition of new myonuclei, these are supplied by
muscle s... hiện toàn bộ
Assisted Reproductive Technology affects developmental kinetics, H19 Imprinting Control Region methylation and H19gene expression in individual mouse embryos
Patricia Fauque, Pierre Jouannet, Corinne Lesaffre, Marie‐Anne Ripoche, Luisa Dandolo, Daniel Vaiman, Hélène Jammes
Abstract Background In the last few years, an increase in imprinting anomalies
has been reported in children born from Assisted Reproductive Technology (ART).
Various clinical and experimental studies also suggest alterations of embryo
development after ART. Therefore, there is a need for studying early epigenetic
anomalies which could result from ART manipulations, especially on single
embryos. I... hiện toàn bộ
Two-color fluorescent in situ hybridization in the embryonic zebrafish brain using differential detection systems - 2011
Gilbert Lauter, Iris Söll, Giselbert Hauptmann
Abstract Background Whole-mount in situ hybridization (WISH) is extensively used
to characterize gene expression patterns in developing and adult brain and other
tissues. To obtain an idea whether a novel gene might be involved in
specification of a distinct brain subdivision, nucleus or neuronal lineage, it
is often useful to correlate its expression with that of a known regional or
neuronal mark... hiện toàn bộ
Expression of miR-1, miR-133a, miR-133b and miR-206 increases during development of human skeletal muscle - 2011
Andrie Koutsoulidou, Nikolaos P. Mastroyiannopoulos, Denis Furling, James B. Uney, Leonidas A. Phylactou
Abstract Background MicroRNAs (miRNAs) are small RNA molecules that
post-transcriptionally regulate gene expression and have been shown to play an
important role during development. miR-1, miR-133a, miR-133b and miR-206 are
expressed in muscle tissue and induced during muscle cell differentiation, a
process that directs myoblasts to differentiate into mature myotubes, which are
organized into myof... hiện toàn bộ
Validation of reference genes for quantitative RT-PCR studies in porcine oocytes and preimplantation embryos Tập 7 Số 1 - 2007
Ewart Kuijk, Leonie du Puy, Helena T A van Tol, Henk P. Haagsman, B. Colenbrander, Bernard A.J. Roelen
Abstract Background In the developing embryo, total RNA abundance fluctuates
caused by functional RNA degradation and zygotic genome activation. These
variations in the transcriptome in early development complicate the choice of
good reference genes for gene expression studies by quantitative real time
polymerase chain reaction. Results In order to identify stably expressed genes
for normalisation... hiện toàn bộ
Pax2 and Pax8 cooperate in mouse inner ear morphogenesis and innervation Tập 10 Số 1 - 2010
Maxime Bouchard, Dominique de Caprona, Meinrad Busslinger, Pin-Xian Xu, Bernd Fritzsch
AbstractBackgroundPax2;5;8transcription factors play diverse roles in vertebrate
and invertebrate organogenesis, including the development of the inner ear. Past
research has suggested various cochlear defects and some vestibular defects
inPax2null mice but the details of the cochlear defects and the interaction with
otherPaxfamily members in ear development remain unclear.ResultsWe show
thatPax2;... hiện toàn bộ
Transcriptional repression and DNA hypermethylation of a small set of ES cell marker genes in male germline stem cells Tập 6 Số 1 - 2006
Makoto Imamura, Kyoko Miura, Kumiko A. Iwabuchi, Tomoko Ichisaka, Masato Nakagawa, Jiyoung Lee, Mito Kanatsu-Shinohara, Takashi Shinohara, Shinya Yamanaka
AbstractBackgroundWe previously identified a set of genes called ECATs (ES
cell-associated transcripts) that are expressed at high levels in mouse ES
cells. Here, we examine the expression and DNA methylation of ECATs in somatic
cells and germ cells.ResultsIn all ECATs examined, the promoter region had low
methylation levels in ES cells, but higher levels in somatic cells. In contrast,
in spite of... hiện toàn bộ
