Disease relevance of Hydrozoa

• We have isolated the serum response factor (SRF) homologue from two hydrozoans, the freshwater polyp Hydra vulgaris and the marine colonial Hydractinia echinata; we have termed the Hydra gene HvSRF and the Hydractinia gene HeSRF [1].
• Multiple stages of Liriope tetraphylla caused paresthesias leading to chafing and excoriations in swimmers along the Southern Uruguayan and Northern Argentinean Atlantic coasts [2].

High impact information on Hydrozoa

• Cnox-2 is a HOM/HOX homeobox gene that we have identified in the simple metazoan Hydra vulgaris (Cnidaria: Hydrozoa) [3].
• Cloning and analysis of the L17 ribosomal protein cDNA from Podocoryne carnea (Coelenterata, Hydrozoa) [4].
• Sars (Coelenterata, Cnidaria, Hydrozoa) stains a fibrillar component of the Podocoryne ECMs in immunohistochemical preparations [5].
• Here we report the isolation of two orthologs of one such gene, nanos (nos), in the cnidarian Podocoryne carnea, a species with representative zoological features among the hydrozoans [6].
• Here we report the identification and characterization of glycine receptors in the freshwater polyp Hydra vulgaris (Cnidaria, Hydrozoa) by biochemical and behavioural studies [7].

Anatomical context of Hydrozoa

• The purpose of this study was to characterize the mode of action of the venom from Portuguese man-of-war (Physalia physalis) on the skeletal muscle vascular bed of dogs anesthetized with sodium pentobarbital (35 mg/kg) [8].
• Mast cell histamine release induced by Portuguese man-of-war (Physalia) venom [9].

Associations of Hydrozoa with chemical compounds

• A fatal case of Physalia physalis (Portuguese man-o'-war) envenomation occurred on the Florida Atlantic coast in 1987 [10].
• Portuguese Man-of-war venom markedly increases calcium (45Ca2+) influx into primary, cultured, embryonic chick heart cells [11].
• Possible involvement of arachidonic acid and eicosanoids in metamorphic events in Hydractinia echinata (Coelenterata; Hydrozoa) [12].
• The effect of verapamil on the cardiotoxic activity of Portuguese man-o'war (Physalia physalis) and sea nettle (Chrysaora quinquecirrha) venoms [13].
• 2. Histochemical, analytic chemical and physiological evidences clearly indicate that dopamine is used as an intercellular messenger in hydrozoans [14].

Gene context of Hydrozoa

• The sera of patients envenomated by the sea nettle (Chrysaora quinquecirrha) or the Portuguese man-o'war (Physalia physalis) were investigated for immune specific and cross-reacting antibodies [15].
• Intraspecific tissue incompatibilities in the metagenetical Podocoryne carnea M. Sars (Cnidaria, Hydrozoa) [16].
