Tomonori Deguchi et al.
G protein-coupled receptors are critical regulators of diverse developmental processes such as oocyte maturation, fertilization, gastrulation, and organogenesis. To further study the molecular mechanisms underlying these processes, we clone...

The capability of regenerating posterior segments and pygidial structures is ancestral for annelids and has been lost only a few times within this phylum. As one of the three major segmented taxa, annelids enable us to monitor reconstructio...
Embryonic development and staging of the cobweb spider Parasteatoda tepidariorum C. L. Koch, 1841 (syn.: Achaearanea tepidariorum; Araneomorphae; Theridiidae) [0.03%]
束网蜘蛛Parasteatoda tepidariorum C. L. Koch, 1841（又名Achaearanea tepidariorum；Araneomorphae；Theridiidae）的胚胎发育及分期

Beate Mittmann
The cobweb spider Parasteatoda tepidariorum (C. L. Koch, 1841; syn.: Achaearanea tepidariorum) has become an important study organism in developmental biology and evolution as well as in genetics. Besides Cupiennius salei, it has become a c...
Phylogenetic analysis and expression patterns of p16 and p19 in Paracentrotus lividus embryos [0.03%]
波西特罗努斯胚胎中p16和p19的系统发育分析及表达模式研究
Caterina Costa,Konstantinos Karakostis,Francesca Zito et al.
Caterina Costa et al.
P16 and P19 are two small acidic proteins involved in the formation of the biomineralized skeleton of sea urchin embryos and adults. Here, we describe the cloning and the embryonic temporal and spatial expression profiles of p16 and p19 mRN...
Super-induction of Dicer-2 expression by alien double-stranded RNAs: an evolutionary ancient response to viral infection? [0.03%]
外源性双链RNA可超强诱导Dicer-2的表达：对病毒感染的古老反应？
Jesus Lozano,Eva Gomez-Orte,How-Jing Lee et al.
Jesus Lozano et al.
Dicer-2 is a ribonuclease involved in the insect RNAi pathway. On attempting to knockdown Dicer-2 expression in the insect Blattella germanica by RNAi, we found that treatment with Dicer-2 dsRNA upregulated the targeted mRNA. This unexpecte...
Cellular and molecular processes leading to embryo formation in sponges: evidences for high conservation of processes throughout animal evolution [0.03%]
海绵胚胎形成过程中细胞和分子层面的机制研究：动物进化历史上保守过程的证据

Alexander V Ereskovsky
The emergence of multicellularity is regarded as one of the major evolutionary events of life. This transition unicellularity/pluricellularity was acquired independently several times (King 2004). The acquisition of multicellularity implies...
Islet1-expressing cardiac progenitor cells: a comparison across species [0.03%]
物种间的比较：表达胰岛素基因1的 cardiac 干细胞
Petra Pandur,Ioan Ovidiu Sirbu,Susanne J Kühl et al.
Petra Pandur et al.
Adult mammalian cardiac stem cells express the LIM-homeodomain transcription factor Islet1 (Isl1). They are considered remnants of Isl1-positive embryonic cardiac progenitor cells. During amniote heart development, Isl1-positive progenitor ...
Rananos expression pattern during oogenesis and early embryonic development in Rhynchosciara americana [0.03%]
Rhynchosciara美洲鼻甲虫卵发生和早期胚胎发育过程中Rananos的表达模式

Paula Rezende-Teixeira
The Dipteran Rhynchosciara americana, a native Brazilian insect that has become a valuable model system for developmental biology research because it provides an interesting opportunity to study a different type of insect oogenesis. Sequenc...
28S rDNA haplotypes of males are distinct from those of androgenetic hermaphrodites in the clam Corbicula leana [0.03%]
青棱蛤Corbicula leana雄性28S rDNA单倍型与雌雄同体的安德氏雄性单倍型不同
Akira Komaru,Shoji Houki,Mitsuya Yamada et al.
Akira Komaru et al.
The clam Corbicula leana exists in two forms, hermaphrodites and males. Our previous study on mitochondrial DNA suggested that the male nuclear DNA might have derived from hermaphrodite C. leana relatively recently. To clarify the origin of...
Coming apart at the seams: morphological evidence for pregnathal head capsule borders in adult Tribolium castaneum [0.03%]
来之不易的证据：成年红谷象头部囊状边界的形态学依据

Cephalization and seamless fusion of the anterior body segments during development obscure the segmental boundaries of the insect head. Most of the visible seams are thought to reflect cuticular infolding for structural reinforcement rather...
