THE EXTRACELLULAR RELEASE OF ECHINOCHROME [PDF]

Journal of General Physiology, 1946
A study was made of the diffusion of the red pigment echinochrome from the eggs of the sea urchin, Arbacia punctulata, into sea water. Unfertilized eggs retained their pigment, over periods of hours. Outward diffusion of pigment from unfertilized eggs normally is entirely negligible, or does not occur at all.

Flaviviridae Viruses and Oxidative Stress: Implications for Viral Pathogenesis

Oxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Oxidative stress is induced once the balance of generation and neutralization of reactive oxygen species (ROS) is broken in the cell, and it plays crucial roles in a variety of natural and diseased processes. Infections of Flaviviridae viruses trigger oxidative stress, which affects both the cellular metabolism and the life cycle of the viruses ...

Pharmacological activity echinochrome a singly and consisting of baa "timarin" [PDF]

Biomeditsinskaya Khimiya, 2012
Pharmacological activity of echinochrome A (EchA) alone and in the biologically active additives (BAA) "Timarin", administered per os has been investigated on volunteers. EchA decreased serum glutatione (GSH) and increased catalase activity 1 h after treatment; catalase activity normalized, while GSH exceeded the initial level 3 h after the treatment ...

Perturbation of gut bacteria induces a coordinated cellular immune response in the purple sea urchin larva

Immunology &Cell Biology, Volume 94, Issue 9, Page 861-874, October 2016., 2016
The purple sea urchin (Strongylocentrotus purpuratus) genome sequence contains a complex repertoire of genes encoding innate immune recognition proteins and homologs of important vertebrate immune regulatory factors. To characterize how this immune system is deployed within an experimentally tractable, intact animal, we investigate the immune ...

The Immune Response of Acanthaster planci to Oxbile Injections and Antibiotic Treatment

Journal of Marine Sciences, Volume 2014, Issue 1, 2014., 2014
Bile salts have been recently identified as a rapid and effective method for killing A. planci. However the mechanistic basis of this new control method is poorly understood. This study explored the immune response(s) of A. planci and/or pathogenesis resulting from the injection of bile salts. To account for the possible role of pathogenesis in causing
