Nodularin Exposure Induces SOD1 Phosphorylation and Disrupts SOD1 Co-localization with Actin Filaments [PDF]
Toxins, 2012 Apoptotic cell death is induced in primary hepatocytes by the Ser/Thr protein phosphatase inhibiting cyanobacterial toxin nodularin after only minutes of exposure. Nodularin-induced apoptosis involves a rapid development of reactive oxygen species (ROS),

Production of the cyanotoxin nodularin—A multifactorial approach [PDF]
Harmful Algae, 2010 Abstract Summer blooms in the Baltic Sea are dominated by the diazotrophic cyanobacteria Nodularia spumigena and Aphanizomenon sp. During the blooms, N. spumigena is concentrated to the water surface and exposed to high irradiances of both photosynthetic active radiation (PAR, 400–700 nm) and ultraviolet radiation (UVR, 280–400 nm), in addition, this

Deposit-feeders accumulate the cyanobacterial toxin nodularin [PDF]
Harmful Algae, 2011 Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production.

Stability of cyanotoxins, microcystin-LR, microcystin-RR and nodularin in seawater and BG-11 medium of different salinity [PDF]
Oceanologia, 2001 Microcystins and nodularin are potent hepatotoxins produced by fresh and seawater cyanobacteria. The persistence of three hepatotoxins - microcystin-LR, microcystin-RR and nodularin - was investigated in sterile BG-11 medium of different salinity and in ...
