Gastrointestinal toxicity induced by microcystins

World Journal of Clinical Cases, 2018
Microcystins (MCs) are produced by certain bloom-forming cyanobacteria that can induce toxicity in various organs, including renal toxicity, reproductive toxicity, cardiotoxicity, and immunosuppressive effects. It has been a significant global environmental issue due to its harm to the aquatic environment and human health.

Nitrogen limitation, toxin synthesis potential, and toxicity of cyanobacterial populations in Lake Okeechobee and the St. Lucie River Estuary, Florida, during the 2016 state of emergency event.

PLoS ONE, 2018
Lake Okeechobee, FL, USA, has been subjected to intensifying cyanobacterial blooms that can spread to the adjacent St. Lucie River and Estuary via natural and anthropogenically-induced flooding events.

Evidence for a novel marine harmful algal bloom: cyanotoxin (microcystin) transfer from land to sea otters.

PLoS ONE, 2010
"Super-blooms" of cyanobacteria that produce potent and environmentally persistent biotoxins (microcystins) are an emerging global health issue in freshwater habitats.

An overview of the toxic effect of potential human carcinogen Microcystin-LR on testis

Toxicology Reports, 2015
The worldwide occurrence of cyanobacterial blooms due to water eutrophication evokes extreme concerns. These blooms produce cyanotoxins which are hazardous to living organisms.

Methods for rapid extraction of microcystin-LR and microcystin-RR

浙江大学学报. 农业与生命科学版, 2005
Simple analysis methods using microwave and boiling waterbath to solve the problem for microcystin-LR (MCLR) and microcystin-RR (MCRR) extraction from cyanobacteria cells were studied as a substitute for the traditional solvent extraction methods. Standards were used to confirm the feasibility and efficiency of both methods.

Microcystins with Modified Adda⁵-Residues from a Heterologous Microcystin Expression System

ACS Omega
Microcystins are hepatotoxic cyclic heptapeptides produced by some cyanobacterial species and usually contain the unusual β-amino acid 3S-amino-9S-methoxy-2S,6,8S-trimethyl-10-phenyl-4E,6E-decadienoic acid (Adda) at position-5. The full microcystin gene cluster from Microcystis aeruginosa PCC 7806 has been expressed in Escherichia coli.

γ-Lindane Increases Microcystin Synthesis in Microcystis aeruginosa PCC7806

Marine Drugs, 2015
HCH factories, and the waste dumpsites associated to its production, have become a global environmental concern, and their runoff could pollute ground and surface waters with high levels of the pollutant.

The use of a benign fast-growing cyanobacterial species to control microcystin synthesis from Microcystis aeruginosa

Frontiers in Microbiology
IntroductionMicrocystis aeruginosa (M. aeruginosa), one of the most abundant blue-green algae in aquatic environments, produces microcystin by causing harmful algal blooms (HABs).

Evaluation of a point-of-use device used for autoantibody analysis and its potential for following microcystin leucine-arginine exposure

Frontiers in Sensors
Introduction: Globally, the need for measuring exposure to algal toxins has become urgent due to ever-increasing reports of contamination in sea and freshwater, in shellfish and fish stocks and in aerosols.Methods: To address this issue, we evaluated the

Evidence for positive selection acting on microcystin synthetase adenylation domains in three cyanobacterial genera

BMC Evolutionary Biology, 2008
Background Cyanobacteria produce a wealth of secondary metabolites, including the group of small cyclic heptapeptide hepatotoxins that constitutes the microcystin family.
