Nitric oxide signaling in ctenophores

Frontiers in Neuroscience, 2023
Nitric oxide (NO) is one of the most ancient and versatile signal molecules across all domains of life. NO signaling might also play an essential role in the origin of animal organization.

Flow cytometry methods for targeted isolation of ctenophore cells

Frontiers in Marine Science, 2023
Cell suspension fluidics, such as flow cytometry (FCS) and fluorescence-activated cell sorting (FACS), facilitates the identification and precise separation of individual cells based on phenotype.

Assessing the Value of a Citizen Science Approach for Ctenophore Identification

Frontiers in Marine Science, 2021
During the era of biodiversity loss, a complete species census and understanding where the different species occur is of high priority. Even though this knowledge has increased tremendously, mainly with expanded use of integrated taxonomic identification,

Sponges, ctenophores, and the statistical significance of syntenies. [PDF]

Mol Biol Evol
Shared fusions between ancestral chromosomal linkage groups have previously been used to support phylogenetic groupings, notably sponges with cnidarians and bilaterians to the exclusion of ctenophores, rendering ctenophores the sister group to all other animals.

Morphological and dietary changes encoded in the genome of Beroe ovata, a ctenophore-eating ctenophore. [PDF]

NAR Genom Bioinform
Abstract As the sister group to all other animals, ctenophores (comb jellies) are important for understanding the emergence and diversification of numerous animal traits. Efforts to explore the evolutionary processes that promoted diversification within Ctenophora are hindered by undersampling genomic diversity within this clade.

Independent specialisation of myosin II paralogues in muscle vs. non-muscle functions during early animal evolution: a ctenophore perspective

BMC Evolutionary Biology, 2012
Background Myosin II (or Myosin Heavy Chain II, MHCII) is a family of molecular motors involved in the contractile activity of animal muscle cells but also in various other cellular processes in non-muscle cells.

Par protein localization during the early development of Mnemiopsis leidyi suggests different modes of epithelial organization in the metazoa

eLife, 2020
In bilaterians and cnidarians, epithelial cell-polarity is regulated by the interactions between Par proteins, Wnt/PCP signaling pathway, and cell-cell adhesion. Par proteins are highly conserved across Metazoa, including ctenophores.

REGULARITIES OF LONG-TERM AND INTERSEASONAL DYNAMICS OF THE CTENOPHORE MNEMIOPSIS LEIDYI POPULATION IN THE CASPIAN SEA

Юг России: экология, развитие, 2014
Results of long-term (2001-2011) monitoring investigations into the distribution of invader Mnemiopsis leidyi population in all major sea areas through the whole year (January-November) are presented. The scenario of invader Mnemiopsis leidyi development

A sticky thicket of glue cells: A comparative morphometric analysis of colloblasts in 20 species of comb jelly (phylum Ctenophora)

Ciencias Marinas, 2020
Ctenophores in the class Tentaculata are distinct from Cnidarians in that they use sticky, not stinging, tentacles to capture and subdue their prey.
