Lineage-specific head development in the coffin-headed cricket Loxoblemmus equestris links the final molt with novel trait evolution [0.03%]
具棺头锥冠猛蚁甲的头部特化发育在最终蜕皮中与新型性状演化相联系
Mizuho Yoneda,Shinichi Morita,Teruyuki Niimi et al.
Mizuho Yoneda et al.
Background: Lineage-specific adult structures form through modifications of pre-existing juvenile body parts during postembryonic development in insects. It remains unclear how these novel traits originate from ancestral ...
Retinoic acid regulates the proliferation, differentiation, and cell death of limb skeletal progenitors, contributing to establish the size and identity of the digits [0.03%]
视黄酸通过调节肢骨祖细胞的增殖、分化和细胞死亡来参与决定手指/趾节数目及大小
Cristina Duarte-Olivenza,Goretti Moran,Juan M Hurle et al.
Cristina Duarte-Olivenza et al.
Background: The development of the digits (fingers/toes) provides an excellent model for analyzing the molecular regulation of skeletal morphogenesis in vertebrates. Digits develop in the autopod as radial chondrogenic co...
The expression of Pax6 and retinal determination genes in the eyeless arachnid A. longisetosus reveals vestigial eye primordia [0.03%]
无眼节足动物A. longisetosus眼睛Pax6和视网膜决定基因的表达揭示了残余眼始基的存在
Isabella Joyce,Austen A Barnett
Isabella Joyce
Background: Evidence suggests that Pax6 genes are necessary for the specification of eyes in a variety of metazoans, including mandibulate arthropods. In these arthropods, Pax6 genes usually interact with a conserved set ...
A subset of conserved phagocytic genes are likely used for the intracellular theft of cnidarian stinging organelles in nudibranch gastropods [0.03%]
一套保守的吞噬基因亚集可能被裸鳃亚纲腹足动物用于刺胞动物刺细胞的胞内窃取作用中
Jessica A Goodheart,Rose Fiorenza,Robin Rio et al.
Jessica A Goodheart et al.
Background: Phagocytosis is a universal physiological process in eukaryotes with many important biological functions. In nudibranch gastropods, a novel form of phagocytosis called nematocyst sequestration is specialized f...

The third iteration of the Cnidarian Model Systems Meeting (Cnidofest) was held August 14-17th, 2024 at Lehigh University in Bethlehem, PA. The meeting featured presentations from laboratories representing 11 countries, covering a broad ran...
The Notch pathway in Metazoa: a comparative analysis across cnidarians and beyond [0.03%]
notch信号通路的进化：基于珊瑚类动物的比较分析
Alena Lövy,Jiří Kyslík,Amparo Picard-Sánchez et al.
Alena Lövy et al.
The Notch signalling pathway is a conserved regulator of cellular processes, including differentiation, proliferation, and apoptosis, across Metazoa. While its roles in bilaterians are well-characterized, the evolutionary history and functi...
Antero-posterior patterning in the brittle star Amphipholis squamata and the evolution of echinoderm body plans [0.03%]
日 كو鱼的前后图案和echinoderm身体计划的进化
L Formery,P Peluso,D R Rank et al.
L Formery et al.
Although the adult pentaradial body plan of echinoderms evolved from a bilateral ancestor, identifying axial homologies between the morphologically divergent echinoderms and their bilaterian relatives has been an enduring problem in zoology...
Microinjection, gene knockdown, and CRISPR-mediated gene knock-in in the hard coral, Astrangia poculata [0.03%]
微注射、基因敲低和CRISPR介导的基因敲入实验在石珊瑚Astrangia poculata中的应用
Jacob F Warner,Ryan Besemer,Alicia Schickle et al.
Jacob F Warner et al.
Cnidarians have become valuable models for understanding many aspects of developmental biology including the evolution of body plan diversity, novel cell type specification, and regeneration. Most of our understanding of gene function durin...
The application of irreversible genomic states to define and trace ancient cell type homologies [0.03%]
不可逆基因组状态的应用以定义和追溯古老的细胞类型同源性
Oleg Simakov,Günter P Wagner
Oleg Simakov
Homology, or relationship among characters by common descent, has been notoriously difficult to assess for many morphological features, and cell types in particular. The ontogenetic origin of morphological traits means that the only physica...
