Algatoxin produces cell death

30.08.2007
The prevalence of algatoxin in the marine environment appears to be increasing.

If ingested, for example in seafood, these toxins can lead to discomfort or even illness. The algatoxin yessotoxin (YTX), which is found in both mussels and scallops in Norway, may be a potential disease risk factor in the consumption of seafood. “We don’t know the long-term effects of YTX on people”, says Mónica Suárez Korsnes of the Norwegian School of Veterinary Science (NVH).

Suárez Korsnes has studied the effects of YTX on muscle cell lines from mice and rats.

“We know that an injection of YTX into the abdomen of animals damages heart muscle. To date, YTX intoxication has never been recorded in people, however, we suspect that long-term exposure to this toxin may lead to damage in humans”, says Suárez Korsnes.

The aim of this research is to establish a basic understanding of the ways in which YTX affects cells in the body. Suárez Korsnes has, in her doctoral work, shown that exposure to YTX can initiate a type of programmed cell death, called apoptosis.

“Apoptosis is a method that the body uses to rid itself of unwanted cells. Some toxins, for example YTX, seem to disrupt this natural mechanism and thereby damage organisms”, explains Suárez Korsnes.

Quality control of seafood

An understanding of how algatoxin can affect organisms is important for the quality control of seafood and for responsible management of marine resources. An increased knowledge of algatoxin may contribute to better surveillance of the food chain and to measures that better protect consumers, producers and exporters of seafood.

More algatoxin than before

During the last few decades, the incidence of algatoxin blooms in the ocean has become more frequent. The reasons for this may include spreading of different types of algae to new seas in the ballast water in ships. Other causes may include increased supply of nutrients from land runoff, and also from the air and rain.

Climatic changes, changes in ocean currents and ecological changes may also explain the increasing prevalence of algatoxin.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
