Influence of Two Depuration Periods on the Activity and Transcription of Antioxidant Enzymes in Tilapia Exposed to Repeated Doses of Cylindrospermopsin under Laboratory Conditions

Toxins, 2014
The cyanobacterial toxin Cylindrospermopsin (CYN), a potent protein synthesis inhibitor, is increasingly being found in freshwater bodies infested by cyanobacterial blooms worldwide.

Total Synthesis of Isotopically-Labeled Cylindrospermopsin Cyanotoxins [PDF]

, 2017
Cyanobacteria, also known as blue-green algae, are prokaryotic organisms that inhabit freshwater and brackish lakes. They produce toxic secondary metabolites known as cyanotoxins, the increased occurrence of which is believed to be a result of ...

Toxicity and uptake mechanism of cylindrospermopsin and lophyrotomin in primary rat hepatocytes

, 2002
The toxicities and uptake mechanisms of two hepatotoxins, namely cylindrospermopsin and lophyrotomin, were investigated on primary rat hepatocytes by using microcystin-LR (a well-known hepatotoxin produced by cyanobacteria) as a comparison.

In silico and in vitro evaluation of potential agonistic and antagonistic estrogenic and androgenic activities of pure cyanotoxins, microcystin-LR and cylindrospermopsin.

Ecotoxicology and Environmental Safety
The potential endocrine disruption activity of cyanotoxins, particularly their effects on estrogen and androgen receptors (ER, AR), remains poorly understood. In the present study, the potential agonistic/antagonistic estrogenic and androgenic activities

Multiplex PCR assay for Cylindrospermopsis raciborskii and cylindrospermopsin-producing cyanobacteria

, 2003
Water bodies are routinely monitored for the presence of potentially toxic cyanobacteria; however, the methodology for confirming toxicity is currently complex and expensive.

New Method for Simultaneous Determination of Microcystins and Cylindrospermopsin in Vegetable Matrices by SPE-UPLC-MS/MS

Toxins, 2018
Cyanotoxins are a large group of noxious metabolites with different chemical structure and mechanisms of action, with a worldwide distribution, producing effects in animals, humans, and crop plants.

Influence of Glycine and Arginine on Cylindrospermopsin Production and aoa Gene Expression in Aphanizomenon ovalisporum

Toxins, 2017
Arginine (Arg) and glycine (Gly) seem to be the only substrates accepted by the amidinotransferase that catalyze the first step of the synthesis pathway of the cyanotoxin cylindrospermopsin (CYN), leading to guanidinoacetate (GAA).

The ecological effects of the cyanobacterial toxin cylindrospermopsin

, 2007
The occurrence of nuisance growths or blooms of cyanobacteria in reservoirs and other waterbodies poses a potential risk to the quality of water as many species are capable of producing secondary metabolites that may be toxic or impart unpleasant taste ...

Validation of a Method for Cylindrospermopsin Determination in Vegetables: Application to Real Samples Such as Lettuce (Lactuca sativa L.)

Toxins, 2018
Reports on the occurrence of the cyanobacterial toxin cylindrospermopsin (CYN) have increased worldwide because of CYN toxic effects in humans and animals.
