anemone flaccida/proline

1. L-proline, by itself or in animal tissue extracts, inhibits the response of the sea anemone Anthopleura elegantissima to the alarm phermone, anthopeurine. 2. The effect of proline is mediated by a receptor that is specific for the structure and configuration of the part of the L-proline molecule

<p>Natural triterpenoid saponins isolated from Anemone flaccida Fr. Schmidt have exhibited anti-cancer properties and exerted remarkable inhibitory effects on tumor growth. Herein, we investigated the potential mechanism involved in the suppression of hepatocellular

Sea anemone venoms have long been recognized as a rich source of peptides with interesting pharmacological and structural properties, but they still contain many uncharacterized bioactive compounds. Here we report the discovery, three-dimensional structure, activity, tissue localization, and

Hair bundles located on tentacles of sea anemones are morphodynamic mechanoreceptors employed to regulate discharge of nematocysts into swimming prey. Activation of chemoreceptors for N-acetylated sugars is known to induce anemone hair bundles to elongate while shifting discharge to lower

Adjustable hair bundle mechanoreceptors located on anemone tentacles detect movements of nearby, swimming prey. The hair bundles are formed by numerous actin-based stereocilia that converge onto a single, central kinocilium. Interestingly, morphological and functional changes to the hair bundles are

Nematocysts from the anemones Aiptasia pallida and Pachycerianthus torreyi were investigated. SDS-polyacrylamide electrophoresis of solubilized Aiptasia nematocysts revealed one major protein band (mol. wt 31,800) and several minor components. Coelectrophoresed whole venom contained numerous protein

A full-length cDNA of cytolysin (Src I) was isolated from the tentacle of Sagartia rosea (a representative species in China) by reverse transcription polymerase chain reaction. The cDNA with an open reading frame of 648 bp encodes a precursor protein of 216 amino acids, which contains a
