Hedgehog signaling patterns the outgrowth of unpaired skeletal appendages in zebrafishBMC Developmental Biology - - 2007
Yavor Hadzhiev, Zsolt Lele, Simone Schindler, Stephen W Wilson, Per Ahlberg, Uwe Strähle, Ferenc Müller
Little is known about the control of the development of vertebrate unpaired
appendages such as the caudal fin, one of the key morphological specializations
of fishes. Recent analysis of lamprey and dogshark median fins suggests the
co-option of some molecular mechanisms between paired and median in
Chondrichthyes. However, the extent to which the molecular mechanisms patterning
paired and median f... hiện toàn bộ
Penetrance of eye defects in mice heterozygous for mutation of Gli3 is enhanced by heterozygous mutation of Pax6BMC Developmental Biology - Tập 6 - Trang 1-11 - 2006
Paulette A Zaki, J Martin Collinson, Junko Toraiwa, T Ian Simpson, David J Price, Jane C Quinn
Knowledge of the consequences of heterozygous mutations of developmentally
important genes is important for understanding human genetic disorders. The Gli3
gene encodes a zinc finger transcription factor and homozygous loss-of-function
mutations of Gli3 are lethal. Humans heterozygous for mutations in this gene
suffer Greig cephalopolysyndactyly or Pallister-Hall syndromes, in which limb
defects a... hiện toàn bộ
A highly conserved regulatory element controls hematopoietic expression of GATA-2in zebrafishBMC Developmental Biology - Tập 7 - Trang 1-13 - 2007
Zhongan Yang, Hong Jiang, Fang Zhao, Deepa B Shankar, Kathleen M Sakamoto, Michael Q Zhang, Shuo Lin
GATA-2 is a transcription factor required for hematopoietic stem cell survival
as well as for neuronal development in vertebrates. It has been shown that
specific expression of GATA-2 in blood progenitor cells requires distal
cis-acting regulatory elements. Identification and characterization of these
elements should help elucidating transcription regulatory mechanisms of GATA-2
expression in hema... hiện toàn bộ
Identification of genes differentially expressed during larval molting and metamorphosis of Helicoverpa armigeraBMC Developmental Biology - Tập 7 - Trang 1-16 - 2007
Du-Juan Dong, Hong-Juan He, Lian-Qin Chai, Xiao-Juan Jiang, Jin-Xing Wang, Xiao-Fan Zhao
Larval molting and metamorphosis are important physiological processes in the
life cycle of the holometabolous insect. We used suppression subtractive
hybridization (SSH) to identify genes differentially expressed during larval
molting and metamorphosis. We performed SSH between tissues from a variety of
developmental stages, including molting 5th and feeding 6th instar larvae,
metamorphically com... hiện toàn bộ
Differences among families in craniofacial shape at early life-stages of Arctic charr (Salvelinus alpinus)BMC Developmental Biology - Tập 20 - Trang 1-15 - 2020

Organismal fitness can be determined at early life-stages, but phenotypic
variation at early life-stages is rarely considered in studies on evolutionary
diversification. The trophic apparatus has been shown to contribute to sympatric
resource-mediated divergence in several taxa. However, processes underlying
diversification in trophic traits are poorly understood. Using phenotypically
variable Ice... hiện toàn bộ
Maternal Oct-4 is a potential key regulator of the developmental competence of mouse oocytesBMC Developmental Biology - Tập 8 - Trang 1-14 - 2008
Maurizio Zuccotti, Valeria Merico, Lucia Sacchi, Michele Bellone, Thore C Brink, Riccardo Bellazzi, Mario Stefanelli, Carlo Alberto Redi, Silvia Garagna, James Adjaye
The maternal contribution of transcripts and proteins supplied to the zygote is
crucial for the progression from a gametic to an embryonic control of
preimplantation development. Here we compared the transcriptional profiles of
two types of mouse MII oocytes, one which is developmentally competent (MIISN
oocyte), the other that ceases development at the 2-cell stage (MIINSN oocyte),
with the aim o... hiện toàn bộ
The lin-35/ Rb and RNAi pathways cooperate to regulate a key cell cycle transition in C. elegansBMC Developmental Biology - Tập 7 Số 1 - Trang 1-16 - 2007
Ouellet, Jimmy, Roy, Richard
The Retinoblastoma gene product (Rb) has been shown to regulate the
transcription of key genes involved in cell growth and proliferation. Consistent
with this, mutations in Rb are associated with numerous types of cancer making
it a critical tumour suppressor gene. Its function is conferred through a large
multiprotein complex that exhibits a dual function in both activation and
repression of gene... hiện toàn bộ
Inactivation of the Huntington's disease gene (Hdh) impairs anterior streak formation and early patterning of the mouse embryoBMC Developmental Biology - Tập 5 - Trang 1-12 - 2005
Juliana M Woda, Teresa Calzonetti, Paige Hilditch-Maguire, Mabel P Duyao, Ronald A Conlon, Marcy E MacDonald
Huntingtin, the HD gene encoded protein mutated by polyglutamine expansion in
Huntington's disease, is required in extraembryonic tissues for proper
gastrulation, implicating its activities in nutrition or patterning of the
developing embryo. To test these possibilities, we have used whole mount in situ
hybridization to examine embryonic patterning and morphogenesis in homozygous
