EvoDevo, 2016 Background Kinorhynchs are ecdysozoan animals with a phylogenetic position close to priapulids and loriciferans. To understand the nature of segmentation within Kinorhyncha and to infer a probable ancestry of segmentation within the last common ancestor ...

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.Heparanase 1 (HPSE1) and Heparanase 2 (HPSE2) exhibit opposing expression patterns and functions in pathological contexts, such as cancer. Here, we describe their specific expression in immune cells and their implications in skin diseases. Although they are structurally similar and considered to be ‘cousins’, we found no common ancestor and that HPSE2 ...

An Ancient Anterior Patterning System Promotes Caudal Repression and Head Formation in Ecdysozoa [PDF]
Current Biology, 2009 Posterior expression of Caudal is required for early embryonic development in nematodes, arthropods, and vertebrates. In Drosophila, ectopic Caudal in anterior cells can induce head defects, and in Caenorhabditis the absence of Caudal in anterior embryonic cells is required for proper development. Anterior Caudal repression in these species is achieved

Molecular Characterization and Functional Analysis of a Putative Octopamine/Tyramine Receptor during the Developmental Stages of the Pacific Oyster, Crassostrea gigas. [PDF]
PLoS ONE, 2016 Octopamine (OA) and its precursor, tyramine (TA), participate in invertebrate development such as growth, maturation, and reproduction by activating their corresponding G protein-coupled receptors (GPCRs).

Molecular determinants archetypical to the phylum Nematoda [PDF]
, 2009 Background Nematoda diverged from other animals between 600–1,200 million years ago and has become one of the most diverse animal phyla on earth. Most nematodes are free-living animals, but many are parasites of plants and animals including humans ...

Cladistics, Volume 41, Issue 3, Page 283-303, June 2025.Abstract Using a new character matrix composed of revised matrices of previous analyses and new morphological findings, the phylogeny of Malacostraca (Pancrustacea) is analysed anew with 207 characters for 35 terminal taxa across all recognized orders. Particular emphasis was placed on methodological versatility, including different degrees of implied ...
