New insights on crinoid (Echinodermata; Crinoidea) bioluminescence

open access: yesFrontiers in Marine Science, 2023
Bioluminescence in echinoderms has been known since the early 19th century. Of the four luminous classes known, Crinoidea is the least studied, with only five bioluminescent species reported.

Structure and function of echinoderm telomerase RNA [PDF]

open access: yes, 2015
: Telomerase is a ribonucleoprotein (RNP) enzyme that requires an integral telomerase RNA (TR) subunit, in addition to the catalytic telomerase reverse transcriptase (TERT), for enzymatic function.

Cellular, Hormonal, and Behavioral Responses of the Holothuroid Cucumaria frondosa to Environmental Stressors

open access: yesFrontiers in Marine Science, 2021
Holothuroids (sea cucumbers) are one of the most ubiquitous groups of benthic animals found across diverse marine ecosystems. As echinoderms, they also occupy an important place in the evolutionary hierarchy, sitting close to vertebrates in the ...

Echinoderm TIMP Sequences [PDF]

open access: yes, 2015
The file contains sequences that belong to the TIMP gene family (tissue inhibitors of metalloproteinases). Different alignments represent the results of successive culling procedures to remove possible non-homologues.

Echinoderm Nervous System [PDF]

open access: yes, 2018
The nervous system of echinoderms has been studied for well over a century. Nonetheless, the information available is disparate, with in-depth descriptions for the nervous component of some groups or of particular organs while scant data is available for

Characterization of NGFFYamide Signaling in Starfish Reveals Roles in Regulation of Feeding Behavior and Locomotory Systems

open access: yesFrontiers in Endocrinology, 2018
Neuropeptides in deuterostomian invertebrates that have an Asn-Gly motif (NG peptides) have been identified as orthologs of vertebrate neuropeptide-S (NPS)-type peptides and protostomian crustacean cardioactive peptide (CCAP)-type neuropeptides.
