Nodularin and cylindrospermopsin: a review of their effects on fish

, 2015
Nodularin (NOD) and cylindrospermopsin (CYN) are hepatotoxic cyanotoxins that are present in numerous ecosystems where bloom episodes occur. In this review, the different effects of both of these cyanotoxins on the different ontogenic stages of various fish species were summarised to clarify the state-of-the-art scientific knowledge on this topic.

Expression of the tumor necrosis factor alpha gene and early response genes by nodularin, a liver tumor promoter, in primary cultured rat hepatocytes. [PDF]

, 1997
Nodularin is a new liver carcinogen possessing a potent tumor-promoting activity in rat liver, mediated through inhibition of protein phosphatases 1 and 2A, and a weak initiating activity. Since we previously reported evidence that nodularin up-regulated

MlrA, an Essential Enzyme for Microcystins and Nodularin on First Step Biodegradation in Microcystin-Degrading Bacteria [PDF]

Microcystin-degrading bacteria first degrade microcystins by microcystinase A (MlrA) to cleave the cyclic structure of microcystins at the Adda-Arg site of microcystin-LR, microcystin-RR, and microcystin-YR, but the cleavage of the other microcystins was

Probable Microcystin Toxicosis in a Red-Gartered Coot (Fulica armillata) from a Protected Coastal Wetland in Central Chile—A Sentinel for Toxic Cyanobacterial Bloom?

Veterinary Sciences
Cyanobacterial harmful algal blooms are an increasing concern for wildlife health, particularly in eutrophic wetlands, yet well-documented avian cases supported by environmental, pathological, and toxicological evidence remain scarce.
