First occurrence of cylindrospermopsin in freshwater in France
Environmental Toxicology, 2008AbstractEleven waterbodies in Western France dominated by cyanobacteria of the genera Aphanizomenon and Anabaena were analyzed in September 2006 for microcystins (MC) and cylindrospermopsin (CYN). CYN was detected for the first time in France in four of them in the presence of Aphanizomenon flos‐aquae and in the presence of Anabaena planctonica in the ...

HPLC-PDA detection of cylindrospermopsin—opportunities and limits
Water Research, 2002The cyanobacterial hepatotoxic alkaloid cylindrospermopsin (CYL) is of increased concern to public health due to the spreading of its main producer, Cylindrospermopsis raciborskii, around the globe. Here we present results of an evaluation of the possibility to analyse environmental samples for their content of CYL based on HPLC with photo diode array ...

TiO2 photocatalytic degradation and detoxification of cylindrospermopsin
Journal of Photochemistry and Photobiology A: Chemistry, 2015Abstract Cylindrospermopsin (CYN), a problematic potent cyanotoxin, is produced during harmful algal blooms and its presence in fresh water lakes and rivers is a threat to human health. UV TiO2 photocatalysis leads to the rapid degradation of CYN following pseudo-first-order kinetics.

Cylindrospermopsin induced transcriptional responses in human hepatoma HepG2 cells
Toxicology in Vitro, 2013The newly emerging cyanotoxin cylindrospermopsin (CYN) is showing genotoxic effects in a range of test systems. However, the knowledge on the mechanisms involved is limited. To get insight into the cellular responses to CYN a toxicogenomic analysis of selected genes commonly affected by genotoxic stress was performed on HepG2 cells exposed to a non ...

Cylindrospermopsin decreases the oxidative burst capacity of human neutrophils
Toxicon, 2014Cylindrospermopsin (CYN), a cyanobacterial toxin, presents a risk to human health due to its relatively high chemical stability, a global spread of its producers and its occurrence in drinking-water reservoirs. Despite a broad interest in its toxicity to eukaryotes, little is known about the potential effects of CYN on the human immune system. Here, we

Natural Photodegradation of the Cyanobacterial Toxins Microcystin and Cylindrospermopsin
Environmental Science & Technology, 2010Microcystins (MC) and cylindrospermopsin (CYN) are potent toxins produced by diverse cyanobacterial genera found in waterbodies throughout the world. In the present study, and in order to achieve a better understanding of the fate of cyanobacterial toxins in the environment, we assessed the photodegradation of MC and CYN along the water column and by ...

Renal tubular damage caused by cylindrospermopsin (cyanotoxin) in mice
Toxicology Letters, 2018Cylindrospermopsin (CYN) is a cyanotoxin and a hydrophilic alkaloid of 415 Da. The principal effect of CYN is the inhibition of protein synthesis, and it can damage various organs. Studies have demonstrated that the kidney is the most affected organ.

Cyanobacterial (blue‐green algal) toxins in water supplies: Cylindrospermopsins
Environmental Toxicology, 2006AbstractThe toxic alkaloid cylindrospermopsin is produced by a range of cyanobacterial species worldwide. It was first identified in the species Cylindrospermopsis raciborskii from tropical waters, and has since been isolated from four other genera in locations ranging from Israel to Japan.

Cylindrospermopsin transformation by manganese-oxidizing bacteria
2021Cylindrospermopsin ist ein hoch persistentes Alkaloid-Toxin, das von Cyanobakterien produziert wird und besonders hepatotoxisch wirkt. Über den mikrobiellen Abbau von Cylindrospermopsin ist nur wenig bekannt und für die wenigen bekannten CYN-abbauende mikrobiellen Isolate und Gemeinschaften konnten bisher keine Transformationsprodukte identifiziert ...
