Further characterization of the PW peptide family that inhibits neuron differentiation in Hydra [0.03%]
水母中抑制神经元分化的PW多肽家族的进一步特征分析
Toshio Takahashi,Osamu Koizumi,Eisuke Hayakawa et al.
Toshio Takahashi et al.
From an evolutionary point of view, Hydra has one of the most primitive nervous systems among metazoans. Two different groups of peptides that affect neuron differentiation were identified in a systematic screening of peptide signaling mole...
The post-embryonic development of Remipedia (Crustacea)--additional results and new insights [0.03%]
无胚后节足动物remipedia(甲壳亚门)的发育成果及新见解

Stefan Koenemann et al.
The post-embryonic development of a species of the enigmatic crustacean group Remipedia is described in detail for the first time under various aspects. Applying a molecular approach, we can clearly prove the species identity of the larvae ...
A novel fusion protein that functions as an enhanced green fluorescent protein reporter and a tetracycline-controlled transcriptional activator [0.03%]

Binary expression systems are widely employed to analyze gene function in vivo using transgenic organisms. The tetracycline-off (Tet-Off) system, which is a binary expression system that uses a tetracycline-controlled transactivator protein...
Evolutionary origin and phylogenetic analysis of the novel oocyte-specific eukaryotic translation initiation factor 4E in Tetrapoda [0.03%]
四足动物卵细胞特异性变体eIF4E的起源及进化分析

The transcriptionally active, growing oocyte accumulates mRNAs essential for early stages of development, the oocyte-to-embryo transition, in a stable, dormant form. Translational repression of mRNAs in eggs of various species is conferred ...
Development of nervous systems to metamorphosis in feeding and non-feeding echinoid larvae, the transition from bilateral to radial symmetry [0.03%]
海胆幼虫在摄食和非摄食状态下从胚后发育至变态期的神经系统发展,以及由两侧对称向辐射对称转变的过程

The development of nervous system (NS) in the non-feeding vestibula larva of the sea urchin, Holopneustes purpurescens, and the feeding echinopluteus larva of Hemicentrotus pulcherrimus was examined by focusing on fate during metamorphosis....
Genomic imprinting in Drosophila has properties of both mammalian and insect imprinting [0.03%]
果蝇基因组印迹具有哺乳动物和昆虫印迹的双重特征
Matthew Anaka,Audra Lynn,Patrick McGinn et al.
Matthew Anaka et al.
Genomic imprinting is a process that marks DNA, causing a change in gene or chromosome behavior, depending on the sex of the transmitting parent. In mammals, most examples of genomic imprinting affect the transcription of individual or smal...
The Tribolium spineless ortholog specifies both larval and adult antennal identity [0.03%]
脊索类似物决定粗糙脉胞蝇幼虫和成虫触角的特征

Teresa D Shippy
The morphology of insect antennae varies widely among species, but our understanding of antennal development comes almost solely from studies of one species-the fruit fly, Drosophila melanogaster. Moreover, this knowledge applies mostly to ...
Loss of spineless function transforms the Tribolium antenna into a thoracic leg with pretarsal, tibiotarsal, and femoral identity [0.03%]
失去spineless功能将Tribolium触角转化为具有跗爪节、胫节和股节身份的胸足
Jane Patricia Toegel,Ernst A Wimmer,Nikola-Michael Prpic
Jane Patricia Toegel
The Drosophila spineless (ss) gene is regulated downstream of the appendage gene Distal-less (Dll) and is involved in leg and antenna development. Specifically, loss of ss leads to the homeotic transformation of the arista, the distalmost a...
And Lophotrochozoa makes three: Notch/Hes signaling in annelid segmentation [0.03%]
翼足动物门有三种 notch/hes信号在环节动物体节形成中的作用
Ajna S Rivera,David A Weisblat
Ajna S Rivera
Segmentation is unquestionably a major factor in the evolution of complex body plans, but how this trait itself evolved is unknown. Approaching this problem requires comparing the molecular mechanisms of segmentation in diverse segmented an...
The amphioxus genome enlightens the evolution of the thyroid hormone signaling pathway [0.03%]
无颌类动物基因组研究揭示甲状腺素信号通路的演化历史
Mathilde Paris,Frédéric Brunet,Gabriel V Markov et al.
Mathilde Paris et al.
Thyroid hormones (THs) have pleiotropic effects on vertebrate development, with amphibian metamorphosis as the most spectacular example. However, developmental functions of THs in non-vertebrate chordates are largely hypothetical and even T...
